Key Takeaways:
- Orphan accounts, also known as abandoned or unmanaged identities, pose a significant security risk to organizations due to their potential for unauthorized access and elevated privileges.
- Traditional Identity and Access Management (IAM) systems are often unable to manage non-human identities, such as service accounts, bots, and agent-AI processes, which can lead to a lack of visibility and control.
- The use of continuous identity audit and telemetry collection can help eliminate orphan accounts and provide full identity observability, reducing the risk of security breaches and compliance exposure.
- Implementing a unified audit trail, role context mapping, and continuous enforcement can help automate the process of identifying and decommissioning unused or unowned accounts.
- Orchid’s Identity Audit capability provides a foundation for continuous insight into identity usage, combining application-level telemetry with automated audit collection to ensure IAM decisions are based on evidence, not estimation.
Introduction to the Problem
The issue of orphan accounts is a growing concern for organizations, as employees, contractors, services, and systems come and go, leaving behind a trail of abandoned or unmanaged identities. These accounts, which can be found across various applications, platforms, assets, and cloud consoles, often remain active even after the original user or owner is no longer associated with the organization. The reason for this is not negligence, but rather the fragmentation of traditional Identity and Access Management (IAM) and Identity Governance and Administration (IGA) systems, which are primarily designed for human users and require manual onboarding and integration for each application.
Why Orphan Accounts are Not Tracked
The main reasons why orphan accounts are not tracked include integration bottlenecks, partial visibility, complex ownership, and the introduction of AI-agents and automation. Every application requires a unique configuration before IAM can manage it, and unmanaged and local systems are rarely prioritized. Additionally, IAM tools only see the "managed" slice of identity, leaving behind local admin accounts, service identities, and legacy systems. The complexity of ownership, due to turnover, mergers, and distributed teams, can also make it unclear who owns which application or account. Furthermore, the introduction of AI-agents and automation has introduced a new category of semi-autonomous identities that act independently from their human operators, further breaking the IAM model.
The Real-World Risk of Orphan Accounts
Orphan accounts pose a significant security risk to organizations, as they can be used by attackers to gain unauthorized access to sensitive data and systems. Several high-profile breaches, such as the Colonial Pipeline attack in 2021 and the manufacturing company hit by Akira ransomware in 2025, have highlighted the dangers of orphan accounts. In both cases, the attackers gained access through old or inactive accounts that had not been deactivated. Orphan accounts can also lead to compliance exposure, operational inefficiency, and incident response drag, as they can violate least-privilege and deprovisioning requirements, inflate license counts, and slow down forensic and remediation efforts.
The Way Forward: Continuous Identity Audit
To eliminate orphan accounts and reduce the associated risks, organizations need to implement a continuous identity audit process. This involves collecting identity telemetry directly from applications, correlating joiner/mover/leaver events, authentication logs, and usage data to confirm ownership and legitimacy, and mapping real usage insights and privilege context into identity profiles. By automating the process of identifying and decommissioning unused or unowned accounts, organizations can reduce the risk of security breaches and compliance exposure. A unified audit trail, role context mapping, and continuous enforcement are also essential components of a continuous identity audit process.
The Orchid Perspective
Orchid’s Identity Audit capability provides a foundation for continuous insight into identity usage, combining application-level telemetry with automated audit collection. This capability delivers verifiable, continuous insight into how identities, including human, non-human, and agent-AI, are actually used. By providing a central identity audit layer, Orchid’s Identity Audit capability can help organizations close the visibility gap and turn orphan accounts from hidden liabilities into measurable, managed entities. This approach ensures that IAM decisions are based on evidence, not estimation, and provides a proactive approach to managing identities and reducing the risk of security breaches.
