Critical Security Alert: CISA Orders Federal Agencies to Replace Outdated Edge Devices
The Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent directive ordering federal agencies to identify and upgrade unsupported edge devices across their networks. This binding operational directive comes in response to what CISA describes as “widespread exploitation campaigns by advanced threat actors” specifically targeting end-of-support network devices. Federal agencies now face strict deadlines to inventory, update, and ultimately replace vulnerable equipment that could serve as entry points for nation-state hackers and other sophisticated adversaries. With the cybersecurity landscape constantly evolving, experts at SecureEdge Solutions recommend organizations take immediate action to protect their network perimeters before malicious actors can exploit these known vulnerabilities.
This directive reflects growing concern about outdated infrastructure components that no longer receive security patches or vendor support, creating significant gaps in federal network defenses. “The risk to federal information systems running EOS edge devices is substantial and constant, resulting in a significant threat to federal property,” the directive states. CISA’s mandate establishes a clear timeline for remediation activities, with initial inventory requirements beginning immediately and complete replacement of vulnerable devices required within 18 months.
What Are Edge Devices and Why They’re Vulnerable
Edge devices represent the boundary between an organization’s internal network and external networks, typically serving as the first line of defense against cyber threats. These critical infrastructure components include devices like routers, firewalls, switches, load balancers, and wireless access points – essentially any hardware that manages, processes, or routes network traffic at the perimeter. When vendors end support for these devices, they stop developing security patches for newly discovered vulnerabilities, creating permanent security gaps that sophisticated attackers can exploit.
The danger posed by unsupported edge devices is particularly severe because of their position in network architecture. These devices often have direct exposure to the internet, making them prime targets for initial compromise attempts. Once breached, they can provide attackers with a foothold to move laterally through networks, exfiltrate sensitive data, or deploy additional malicious payloads. Without regular security updates, even known vulnerabilities remain unpatched indefinitely, giving attackers ample opportunity to develop and refine exploitation techniques.
Common Edge Devices in Federal Networks
Federal agencies typically employ a wide range of edge devices to manage their complex network environments. These include enterprise-grade routers from manufacturers like Cisco, Juniper, and Palo Alto Networks that direct traffic between networks. Next-generation firewalls that provide deep packet inspection and threat prevention capabilities are also common, alongside load balancers that distribute network traffic across multiple servers to ensure availability and performance. Many agencies also rely on specialized security appliances like web application firewalls, intrusion prevention systems, and SSL/TLS inspection devices to protect their web-facing resources.
Wireless infrastructure components such as wireless controllers and access points also qualify as edge devices under the CISA directive when they provide connectivity between internal networks and external devices. Legacy VPN concentrators, often deployed during rapid remote work transitions, are particularly problematic as many older models have reached end-of-support status while remaining in active service. Network switches at demarcation points between trusted and untrusted networks round out the typical edge device ecosystem found in federal environments.
End-of-Support Vulnerabilities Hackers Exploit
Unsupported edge devices harbor numerous vulnerabilities that sophisticated threat actors actively target. Firmware flaws in these devices often remain unpatched indefinitely, creating permanent security gaps that attackers can reliably exploit. Deprecated encryption protocols and weak authentication mechanisms in older devices fail to meet modern security standards, potentially allowing attackers to intercept sensitive communications or gain unauthorized access. Hard-coded credentials and backdoor accounts, occasionally discovered years after a product’s release, become permanent vulnerabilities when vendors no longer issue security fixes.
Buffer overflow and command injection vulnerabilities in device management interfaces present particularly attractive targets, as they often allow attackers to execute arbitrary code with elevated privileges. Denial-of-service vulnerabilities in traffic processing components can be exploited to disrupt agency operations or as a distraction during more sophisticated attacks. Perhaps most concerning, default configurations and known misconfigurations of legacy devices are well-documented in attacker playbooks, allowing less sophisticated actors to successfully compromise federal networks using widely available exploitation techniques.
The “EOS Edge Device List” – CISA’s New Resource
To support agencies in identifying vulnerable infrastructure, CISA has developed a specialized “EOS Edge Device List” as part of this directive. This preliminary repository contains detailed information about devices that are already past their end-of-support date or will soon reach that status. The list includes device types, vendors, specific model numbers, and critical end-of-support dates that agencies must reference during their inventory processes. CISA officials have indicated this list will not be made public, likely to avoid providing a targeting roadmap for potential attackers.
Agencies must use this resource as the foundation for their compliance efforts, cross-referencing their existing inventory against CISA’s list to identify at-risk devices. The directive requires agencies to report their findings back to CISA using a standardized template, creating a government-wide view of vulnerable edge infrastructure. As agencies work through remediation, this centralized tracking mechanism will help CISA monitor progress and identify sectors or device categories that may require additional support or resources.
The EOS Edge Device List will be continuously updated as vendors announce new end-of-support dates or as CISA identifies additional vulnerable device categories. This dynamic approach acknowledges the constant evolution of the threat landscape and provides agencies with an ongoing reference point for vulnerability management. By maintaining this centralized repository, CISA aims to eliminate information gaps that might otherwise allow vulnerable devices to remain in production environments.
CISA’s Binding Operational Directive Timeline
CISA’s directive establishes a stringent timeline for agencies to address unsupported edge device vulnerabilities across federal networks. The phased approach balances the urgency of the threat with practical considerations for resource allocation and operational continuity. Agencies must take immediate action to begin identifying vulnerable devices, with critical deadlines spaced over an 18-month period to ensure complete remediation of the identified security gaps. This structured timeline recognizes that wholesale replacement of network infrastructure requires careful planning and execution to avoid disruption to essential government services.
The directive’s requirements are non-negotiable for federal agencies, representing one of the most aggressive cybersecurity mandates in recent years. CISA’s authority to issue binding operational directives stems from the Federal Information Security Modernization Act (FISMA), giving these requirements the force of law for federal executive branch departments and agencies. While state and local governments aren’t directly bound by these requirements, security experts strongly recommend they follow the same timeline and procedures to protect their own networks from similar threats.
Many agencies will need to accelerate planned refresh cycles and reprioritize IT modernization budgets to meet these aggressive timelines. The directive acknowledges this challenge by including provisions for temporary exemptions in cases where immediate replacement would compromise critical mission functions. However, these exceptions require formal documentation and additional compensating controls to mitigate the risks until replacement becomes feasible.
Immediate Actions Required
From the moment the directive was issued, federal agencies are required to begin updating all edge devices that can be patched to vendor-supported software and firmware versions. This immediate requirement focuses on addressing the “low-hanging fruit” – devices that are still supported but running outdated software. Agencies must also immediately review their network security architecture to implement additional protections for any devices that cannot be immediately updated or replaced. These compensating controls might include enhanced network segmentation, more restrictive access controls, or deployment of additional monitoring capabilities to detect suspicious activity involving vulnerable devices.
3-Month Identification Deadline
Within three months of the directive’s issuance, agencies must complete a comprehensive inventory of all edge devices within their environments. This inventory must specifically identify any devices that are already past their end-of-support date or will reach that status within the next twelve months. The complete inventory must be submitted to CISA using a standardized template, allowing for government-wide visibility into vulnerable infrastructure components. This discovery phase is critical, as many agencies may lack complete visibility into all edge devices operating within their extended network environments, particularly in remote locations or specialized operational technology networks.
12-Month Replacement Planning
By the twelve-month mark, agencies must develop detailed remediation plans for all identified end-of-support devices. These plans must include specific timelines, resource requirements, and technical approaches for replacing vulnerable infrastructure. Agencies must begin actively removing and replacing devices listed in the CISA EOS Edge Device List with vendor-supported alternatives capable of receiving security updates. This phase requires close coordination with procurement teams to ensure replacement hardware is available when needed, particularly important given ongoing supply chain challenges affecting technology hardware.
18-Month Final Implementation
The directive sets an eighteen-month deadline for agencies to complete the decommissioning of all end-of-support edge devices from federal networks. By this final deadline, agencies must have replaced all vulnerable infrastructure with vendor-supported alternatives or received formal exceptions for specific devices that cannot be replaced due to mission-critical requirements. This final phase represents the completion of a massive infrastructure modernization effort across the federal government, significantly reducing the attack surface presented by outdated and vulnerable network components.
Threat Intelligence: Nation-State Actors Target Outdated Devices
CISA’s directive comes in direct response to substantial evidence that sophisticated threat actors, particularly nation-state sponsored groups, are systematically targeting unsupported edge devices as preferred attack vectors. Intelligence agencies have observed a significant increase in reconnaissance activities specifically scanning for vulnerable edge devices across federal networks. These targeted campaigns often begin with detailed fingerprinting to identify specific device models, firmware versions, and potential vulnerabilities before launching tailored exploitation attempts. The attackers demonstrate impressive patience, sometimes maintaining access to compromised devices for months before expanding their foothold into protected networks.
The technical sophistication of these attacks has increased dramatically, with adversaries developing custom exploitation tools specifically designed to compromise particular models of outdated edge devices. Security researchers have documented multiple zero-day vulnerabilities being exploited in the wild before they were publicly disclosed, suggesting some threat actors maintain dedicated research teams focused on discovering new vulnerabilities in common edge device platforms. These capabilities were previously associated only with the most advanced threat actors, but are now observed across a wider range of adversary groups.
Intelligence reports indicate that multiple foreign intelligence services have established specialized units dedicated to compromising network infrastructure components as a primary method of gaining persistent access to target organizations. These units methodically catalog vulnerable devices, develop exploitation techniques, and maintain databases of potential targets sorted by strategic priority. The systematic nature of these operations represents a significant shift from opportunistic attacks to strategic campaigns designed to establish persistent access to high-value networks.
Attack Pattern Analysis: Edge Device Exploitation
• Initial Access: Exploitation of public-facing edge device vulnerabilities
• Persistence: Installation of modified firmware with backdoor capabilities
• Defense Evasion: Targeting devices not covered by standard EDR solutions
• Command & Control: Encrypted tunneling through compromised edge devices
• Lateral Movement: Use of edge device access to breach internal networks
The consequences of these compromises extend far beyond the initial breach. Attackers who gain control of edge devices can intercept and manipulate network traffic, potentially accessing sensitive information or disrupting critical operations. In multiple documented cases, compromised edge devices have been used to establish persistent access that remained undetected for extended periods, allowing attackers to gradually expand their access and exfiltrate large volumes of sensitive data. The strategic value of these devices makes them particularly attractive targets for sophisticated threat actors with long-term intelligence gathering objectives.
Current Exploitation Campaigns
Recent Federal Network Incidents Linked to Edge Device Vulnerabilities
• Multiple agencies reported unauthorized access via legacy VPN concentrators
• Compromised load balancers used to inject malicious code into web applications
• Outdated wireless controllers exploited to establish persistent network access
• Legacy firewall devices modified to allow covert data exfiltration channels
• Router compromise enabling traffic interception and man-in-the-middle attacks
CISA’s incident response teams have documented multiple cases where unsupported edge devices served as the initial entry point for sophisticated attacks against federal networks. In several instances, attackers exploited vulnerabilities in edge devices that had been public knowledge for years but remained unpatched due to lack of vendor support. These incidents typically involved careful reconnaissance to identify vulnerable devices, followed by targeted exploitation attempts using both public and private exploit code. Once access was established, attackers demonstrated sophisticated post-exploitation techniques to maintain persistence and expand their access to protected resources.
Particularly concerning are cases where attackers modified device firmware to include backdoor capabilities, effectively creating permanent access that survived routine maintenance procedures. These modifications were often subtle enough to avoid detection through standard monitoring practices, allowing attackers to maintain access for extended periods. In some cases, compromised devices were used to intercept and decrypt sensitive network traffic, potentially exposing authentication credentials and other sensitive information to unauthorized access.
Recent months have seen a significant increase in both the volume and sophistication of these attacks, with multiple federal agencies reporting similar patterns of attempted exploitation targeting their edge infrastructure. This trend suggests a coordinated campaign by one or more advanced threat actors specifically focusing on these vulnerable components as preferred entry points to federal networks. The timing and technical similarities between these attempts suggest they may be part of a broader strategic operation rather than isolated incidents.
D-Link Router Vulnerabilities
Recent security research has highlighted D-Link routers as particularly vulnerable targets in the current threat landscape. Many older D-Link models have reached end-of-support status yet remain widely deployed across government networks, especially in remote locations and satellite offices. Security researchers have documented multiple critical vulnerabilities in these devices, including authentication bypass flaws, command injection vulnerabilities, and hard-coded credentials that allow complete device takeover. These vulnerabilities are well-documented in attacker communities and exploit code is readily available through various channels.
The consequences of these D-Link vulnerabilities were demonstrated in a recent incident where attackers compromised multiple agency networks through outdated D-Link VPN routers at branch offices. The attackers exploited known vulnerabilities to establish persistent access, then used these compromised devices as launching points for further network intrusion. This attack pattern perfectly illustrates why CISA has prioritized the replacement of such devices in its directive, as even a single vulnerable edge device can compromise an otherwise well-defended network.
Chinese State-Sponsored Espionage Concerns
Intelligence agencies have specifically identified Chinese state-sponsored threat actors as particularly active in targeting unsupported edge devices. Groups like APT41, Volt Typhoon, and other Chinese Ministry of State Security (MSS) affiliated teams have demonstrated sophisticated capabilities for compromising network infrastructure components. These groups maintain extensive catalogs of vulnerabilities in common edge devices and have developed specialized tools for exploiting these weaknesses at scale. Their targeting patterns suggest a strategic focus on establishing persistent access to government networks through these often-overlooked infrastructure components.
The technical sophistication of these operations has increased dramatically in recent years, with Chinese threat actors developing custom implants specifically designed for particular edge device models. These malicious firmware modifications are often designed to survive factory resets and standard troubleshooting procedures, creating persistent access that can be extremely difficult to detect and remove. The strategic patience demonstrated by these actors is particularly concerning, with some compromises remaining undetected for months or even years while attackers slowly gather intelligence and expand their access within targeted networks.
How to Comply with the CISA Mandate
Effective compliance with CISA’s directive requires a structured approach to discovering, assessing, and remediating vulnerable edge devices across agency networks. Organizations must begin by establishing a dedicated project team with clear authority and responsibility for implementing the directive’s requirements. This team should include representatives from network operations, cybersecurity, procurement, and mission-critical application owners to ensure all perspectives are considered. Executive sponsorship is essential, as this initiative will require significant resources and may impact operational capabilities during the transition period.
Agencies should develop a detailed project plan that maps to CISA’s timeline while accounting for their specific organizational constraints. This plan should include clear milestones for each phase of the directive, specific roles and responsibilities for implementation teams, and detailed documentation requirements to demonstrate compliance. Resource planning is particularly critical, as many agencies will need to accelerate planned refresh cycles and reprioritize budgets to fund the required replacements. Early engagement with procurement teams can help identify potential supply chain challenges and develop strategies to secure necessary hardware within the required timeframes.
Identify All Edge Devices in Your Network
The first critical step in compliance is conducting a comprehensive inventory of all edge devices operating within agency networks. This discovery process should leverage multiple data sources including network management systems, configuration management databases, asset management tools, and physical site surveys. Automated scanning tools can help identify devices that may not be properly documented in existing inventory systems, particularly in remote locations or specialized operational technology networks. For complex environments, consider engaging specialized contractors with expertise in network discovery and documentation to ensure complete visibility.
Agencies with distributed or global footprints should implement a phased discovery approach, prioritizing internet-facing and mission-critical networks before expanding to lower-risk environments. The inventory process should capture detailed information about each device including make, model, firmware version, configuration details, and current operational role. This information will be essential for cross-referencing against CISA’s EOS Edge Device List and determining appropriate remediation strategies. Document all inventory findings in a centralized repository that can be easily updated as the project progresses and shared with CISA as required.
Determine Support Status and Patch Levels
Once inventory is complete, agencies must assess each device’s support status by referencing vendor documentation, support contracts, and CISA’s EOS Edge Device List. Determine whether each device is currently supported, approaching end-of-support, or already unsupported and document these findings for each inventory item. For devices that remain supported, assess current firmware/software versions against vendor recommendations to identify any that require immediate updates to address known vulnerabilities. Document all findings in a central repository that tracks each device’s current status, required actions, and compliance timeline.
For devices approaching end-of-support but not yet expired, develop a timeline showing when vendor support will end and how this aligns with CISA’s remediation deadlines. Contact vendors directly to confirm exact support end dates and whether any extended support options might be available for critical devices. This assessment phase should result in a prioritized list of devices requiring replacement, with clear timelines for when each device must be decommissioned to maintain compliance with the directive’s requirements.
Develop Migration Strategy for Unsupported Equipment
Based on the inventory and assessment results, develop comprehensive migration strategies for replacing unsupported edge devices. These strategies should account for the technical complexity of each replacement, potential impacts on dependent systems, and operational considerations to minimize service disruptions. Group similar devices together to develop standardized replacement procedures that can be efficiently implemented across multiple locations. Identify whether direct replacement with newer models is possible or if architectural changes will be required to accommodate modern alternatives with different capabilities or requirements.
- For simple replacements, develop standardized procedures for like-for-like migrations with minimal configuration changes
- For complex replacements requiring architectural changes, develop detailed design documents showing both current and target states
- Identify any dependencies that might impact the replacement timeline, such as circuit upgrades or physical infrastructure changes
- Develop detailed testing plans to validate replacement devices meet functional and security requirements
- Create rollback procedures for each replacement to mitigate risk in case of unexpected issues
Document Exceptions for Mission-Critical Systems
CISA’s directive recognizes that some unsupported devices may be essential components of mission-critical systems that cannot be immediately replaced without significant operational impact. In these exceptional cases, agencies must document formal exception requests with detailed justification and risk mitigation plans. These exception requests must clearly explain why immediate replacement is not feasible, provide a specific timeline for eventual replacement, and detail the compensating controls that will be implemented to protect the vulnerable device until replacement can occur. All exception requests require senior leadership approval and must be submitted to CISA for review.
Compensating controls for excepted devices should include enhanced network segmentation to isolate the vulnerable device, additional monitoring capabilities to detect potential compromise, and strict access controls to limit exposure. Document these controls in detail and implement regular testing to verify their effectiveness. Even with approved exceptions, agencies should continue actively working toward replacement solutions to minimize the duration of this elevated risk posture. Consider creative approaches such as parallel deployments that allow mission functions to gradually transition to new infrastructure without abrupt cutover events.
Implement Continuous Monitoring
Throughout the compliance process, agencies must implement enhanced monitoring for all edge devices, particularly those identified as vulnerable or awaiting replacement. This monitoring should include both automated and manual components designed to quickly detect potential compromise or suspicious activity. Configure network monitoring tools to alert on unusual traffic patterns, unexpected configuration changes, or connection attempts from suspicious sources. Implement regular vulnerability scanning specifically targeting edge devices to identify new vulnerabilities as they emerge.
Establish a dedicated security operations team responsible for monitoring alerts related to edge device security and responding to potential incidents. This team should have clear escalation procedures and response playbooks specifically designed for edge device compromise scenarios. Document all monitoring activities and findings as part of the overall compliance effort, providing clear evidence that vulnerable devices are being appropriately protected during the transition period. This monitoring capability will remain valuable even after all replacements are complete, as it provides an early warning system for potential security issues affecting the new infrastructure.
Securing Your Agency Network Beyond Compliance
While CISA’s directive focuses specifically on replacing unsupported edge devices, truly effective network security requires a more comprehensive approach. Forward-thinking security leaders should use this mandate as an opportunity to implement broader security improvements that address not just current vulnerabilities but also establish sustainable practices for maintaining robust network security posture over time. This more holistic approach can transform a compliance-driven project into a strategic security enhancement initiative with long-term benefits for the organization’s overall risk management capabilities.
Defense-in-Depth Strategies
Implement a multi-layered defense strategy that protects networks even if edge devices are compromised. This should include network segmentation using internal firewalls and micro-segmentation techniques to contain potential breaches and limit lateral movement. Deploy advanced threat detection technologies including network traffic analysis (NTA) tools that can identify suspicious patterns even in encrypted traffic streams. Implement zero trust architecture principles that require continuous verification rather than assuming devices within the perimeter are trustworthy.
Enhance endpoint protection beyond traditional antivirus with modern endpoint detection and response (EDR) solutions that can identify suspicious behaviors and contain threats before they spread. Implement comprehensive logging and security information and event management (SIEM) solutions to centralize security data and enable rapid detection of potential compromise. Regular penetration testing should specifically target edge infrastructure to identify vulnerabilities before attackers can exploit them. This defense-in-depth approach ensures that security doesn’t depend entirely on the integrity of perimeter devices.
Vendor Management Best Practices
Develop systematic approaches to tracking vendor support lifecycles for all critical infrastructure components, not just current edge devices. Establish a centralized database tracking support end dates for all network components, with automated alerting for devices approaching end-of-support milestones. Implement formal policies requiring security reviews before procurement of new network equipment, ensuring only devices with appropriate security capabilities and support commitments enter the environment. Consider requiring vendors to contractually commit to minimum support periods and vulnerability disclosure practices as part of procurement agreements.
Create formal vendor management processes that include regular security assessment of critical technology providers. This should include verification of their security development practices, vulnerability management processes, and responsiveness to security issues. Establish direct relationships with vendor security teams to ensure rapid communication about emerging threats and vulnerabilities. Consider joining industry information sharing groups specific to network infrastructure security to gain early awareness of emerging vulnerabilities and mitigation strategies before they become public knowledge.
Lifecycle Planning for Network Equipment
Implement formal technology lifecycle management processes that anticipate replacement needs before devices reach end-of-support status. This proactive approach should include regular technology refresh planning integrated with budgeting cycles to ensure funding is available when replacements become necessary. Develop standardized architectures and approved product lists that simplify future migrations by limiting technological diversity and ensuring new acquisitions align with strategic security capabilities. Consider establishing rolling refresh programs that replace portions of the infrastructure each year rather than facing wholesale replacement requirements.
Document detailed network architecture and configuration information in a centralized system to simplify future migrations and ensure complete visibility into the environment. Implement automation for configuration management and deployment to ensure consistent security controls across all infrastructure components. Establish formal change management processes that include security review requirements for all infrastructure modifications. This lifecycle approach transforms reactive security patching into strategic technology management, significantly reducing future vulnerability windows.

Frequently Asked Questions
CISA’s directive has generated numerous questions as agencies begin their compliance efforts. The following answers address the most common concerns based on current guidance and best practices for implementation.
What exactly qualifies as an “edge device” under the CISA directive?
Under the CISA directive, an edge device is defined as any network infrastructure component that operates at the boundary between an organization’s internal network and external networks or untrusted zones. This includes devices that route traffic between networks, provide security functions, or enable external connectivity. Specific examples include routers, firewalls, VPN concentrators, load balancers, proxy servers, security gateways, wireless controllers, and similar devices that process or manage network traffic at organizational boundaries. The directive specifically focuses on hardware devices rather than software-based virtual appliances, though virtual instances running on end-of-support hardware would still fall within scope.
Do agencies need special permission for devices they can’t immediately upgrade?
Yes, agencies must request formal exceptions for any unsupported devices that cannot be replaced within the mandated timeline. These exception requests must include detailed justification explaining why immediate replacement is not feasible, specific timelines for when replacement will occur, and comprehensive descriptions of compensating controls that will be implemented to mitigate risk in the interim. All exception requests require approval from the agency’s Chief Information Officer or equivalent senior official and must be submitted to CISA using standardized templates provided as part of the directive. CISA will review these requests and may require additional compensating controls before granting exceptions.
How will CISA monitor agency compliance with this directive?
CISA will track compliance through multiple mechanisms including required progress reports submitted by agencies at each major deadline. Agencies must provide complete device inventories, remediation plans, and status updates using standardized templates that allow for government-wide analysis of progress and risk. Additionally, CISA will leverage data from Continuous Diagnostics and Mitigation (CDM) program sensors and federal network monitoring systems to independently verify the presence or absence of vulnerable devices. CISA may also conduct targeted assessments or red team exercises to validate compliance and effectiveness of security controls, particularly for high-value networks or agencies with significant numbers of exception requests.
What penalties might agencies face for non-compliance?
CISA’s binding operational directives carry the force of law for federal executive branch agencies, making compliance mandatory rather than optional. While the directive itself doesn’t specify explicit penalties for non-compliance, agencies that fail to meet requirements may face various consequences. These could include increased oversight from Congress, negative findings in FISMA compliance assessments, budget implications, or public identification in CISA’s annual compliance reports. More significantly, non-compliant agencies face substantially increased cybersecurity risk, potentially leading to breaches that could trigger more severe consequences including leadership accountability reviews and potential administrative actions.
Additionally, agencies with poor compliance records may face restrictions on their authority to independently operate information systems, requiring additional approvals for technology deployments or changes. In extreme cases of non-compliance affecting critical infrastructure or national security systems, agency leaders could be called to testify before congressional oversight committees regarding their failure to address known security vulnerabilities. Most importantly, agencies that fail to comply face significantly elevated risk of compromise that could impact their ability to deliver essential government services.
Are contractors and third-party vendors subject to the same requirements?
The directive applies to all information systems owned or operated by or on behalf of federal agencies, including those managed by contractors, cloud service providers, and other third parties. Agency contracts with service providers must include requirements for compliance with all applicable federal security directives, including this one. Agencies are responsible for ensuring their contractors identify and remediate unsupported edge devices according to the same timelines and requirements that apply to agency-operated systems. This includes systems operated in contractor facilities or cloud environments that process federal information.
Agencies should immediately review existing contracts to confirm they include appropriate requirements for compliance with federal security directives. Where necessary, contracting officers should issue formal modifications or clarifications to ensure vendors understand their obligations under this directive. Agencies should require vendors to provide detailed inventories of edge devices supporting federal information systems and verification that these devices receive appropriate security updates. For new acquisitions, agencies should explicitly include compliance requirements in statements of work and evaluate vendor proposals based in part on their ability to maintain properly supported infrastructure.
The comprehensive security of federal networks requires a unified approach across all operating environments, regardless of who manages the underlying infrastructure. By extending these requirements to contractors and service providers, CISA ensures that sophisticated attackers cannot simply shift their focus from agency-operated systems to third-party environments supporting the same mission functions. This holistic approach reflects the reality that modern government operations depend on a complex ecosystem of internal and external service providers, all of which must maintain appropriate security standards to protect federal information.
