Survey Methodology and Scope
Oxford Economics partnered with Splunk to conduct the second edition of the CISO report, surveying 650 Chief Information Security Officers between July and August 2025. The respondents represented a diverse mix of industries, company sizes, and geographic regions, ensuring a broad view of current security leadership challenges. The study aimed to capture how the CISO role is evolving in response to emerging technologies, particularly artificial intelligence, and to identify the strategies CISOs employ to align security initiatives with broader business objectives. By focusing on senior security leaders, the report provides insight into the strategic, operational, and personal pressures shaping modern cybersecurity management.
Expanding Responsibilities of the CISO
Findings reveal that the CISO’s mandate is expanding at a pace that many leaders struggle to keep up with. Beyond overseeing firewalls, intrusion detection, and incident response, CISOs now own AI governance—ensuring that machine‑learning models are developed, deployed, and monitored securely. They also bear responsibility for securing the software development lifecycle, integrating security controls into DevOps pipelines, and managing third‑party risk. Additionally, the report notes a growing trend of personal liability for security incidents, with CISOs facing potential legal and financial repercussions when breaches occur. This widening scope demands a blend of technical depth, regulatory knowledge, and leadership acumen.
AI Governance as a Core Duty
Artificial intelligence has moved from an experimental tool to a core component of enterprise operations, and CISOs are at the forefront of managing its risks. The survey shows that a majority of respondents now lead AI ethics committees, establish model‑validation frameworks, and monitor for adversarial attacks such as data poisoning or model extraction. AI‑generated deep‑fake phishing campaigns present a new social‑engineering threat that traditional email filters struggle to detect, prompting CISOs to invest in advanced detection technologies and employee awareness programs. By embedding security considerations into AI model lifecycles, CISOs aim to harness productivity gains while mitigating the unique vulnerabilities that intelligent systems introduce.
Secure Software Development and DevSecOps
The report highlights that secure software development has become a non‑negotiable component of the CISO portfolio. Leaders are advocating for the adoption of DevSecOps practices, where security testing is integrated early and continuously throughout the development process. This shift reduces the cost and complexity of fixing vulnerabilities post‑release and aligns with the broader trend of delivering software at speed without compromising safety. CISOs are also pushing for standardized secure‑coding guidelines, automated dependency scanning, and runtime protection measures to defend against self‑mutating malware that can evade traditional signature‑based defenses.
Mounting Personal Liability and Accountability
An emerging concern identified in the survey is the increasing personal liability that CISOs face following security incidents. Regulatory bodies in several jurisdictions are beginning to hold individuals accountable for failures to implement reasonable security controls, and executive contracts now often include clauses linking compensation to security performance. This reality pushes CISOs to adopt rigorous documentation practices, maintain up-to‑date risk registers, and ensure that board-level reporting is transparent and evidence‑based. The heightened stakes underscore the need for CISOs to balance technical expertise with legal awareness and proactive risk mitigation.
Threat Landscape: Sophistication and Evolution
Even as their responsibilities grow, CISOs confront a threat landscape that is becoming more sophisticated and harder to predict. Attackers are leveraging AI to craft convincing deep‑fake videos and audio for social‑engineering schemes, while malware developers are creating self‑mutating strains that alter their code to evade detection. These advances necessitate a move beyond reactive defenses toward adaptive, intelligence‑driven security operations. CISOs reported investing in threat‑hunting teams, behavioral analytics, and AI‑powered security information and event management (SIEM) systems to stay ahead of adversaries who can now automate and scale their attacks at unprecedented rates.
Shifting from Defense to Proactive Strategy
Despite the daunting threat environment, the report finds that CISOs are not merely playing defense. A significant proportion are prioritizing proactive initiatives such as red‑team exercises, continuous penetration testing, and the establishment of security champions programs across business units. By fostering a culture where security is everyone’s responsibility, CISOs aim to reduce the attack surface and improve organizational resilience. This shift reflects a broader recognition that security must be embedded in business processes rather than bolted on as an afterthought.
Investing in Talent Over Technology
A striking trend uncovered by the survey is the preference for investing in skilled personnel rather than solely acquiring new security tools. CISOs cited the scarcity of qualified cybersecurity professionals as a top barrier, yet they recognize that technology alone cannot compensate for gaps in expertise. Consequently, many are allocating budgets to upskilling existing staff, hiring diverse talent pools, and partnering with academic institutions to build pipelines of future experts. This people‑centric approach is viewed as essential for managing complex threats like AI‑generated attacks and for sustaining long‑term security maturity.
Forging Joint Accountability with C‑Suite Peers
To address the expanding scope of their role, CISOs are increasingly seeking joint accountability with other C‑suite executives. The report notes that leaders are forming cross‑functional risk committees that include the CEO, CFO, COO, and Chief Legal Officer, ensuring that security considerations are woven into strategic decisions such as mergers and acquisitions, product launches, and digital transformation initiatives. By sharing ownership of risk, CISOs can secure the necessary resources and executive sponsorship to implement comprehensive security programs that align with business goals.
Translating Technical Risk into Business Language
A critical skill highlighted in the survey is the ability of CISOs to translate technical risk into language that resonates with the board and other non‑technical stakeholders. Leaders are adopting risk‑quantification frameworks, presenting potential financial impacts of breach scenarios, and linking security investments to key performance indicators such as system uptime, customer trust, and regulatory compliance. This business‑oriented communication helps CISOs secure budget approvals, demonstrate ROI, and position security as an enabler of innovation rather than a hindrance.
Proving ROI and Bridging the Knowledge Gap
The report underscores the ongoing effort by CISOs to prove the return on investment of security spend. By leveraging metrics such as mean time to detect (MTTD), mean time to respond (MTTR), and reduction in incident frequency, CISOs can illustrate how security improvements directly affect operational efficiency and cost savings. Additionally, they are actively working to bridge the cybersecurity knowledge gap with leadership through regular briefings, tabletop exercises, and tailored training sessions that demystify technical concepts and emphasize strategic implications.
From Cost Center to Driver of Business Resilience
Finally, the findings reveal a paradigm shift: security is increasingly viewed not as a cost center but as a genuine driver of business resilience. Organizations that integrate security into their core strategy report faster recovery from incidents, higher customer confidence, and greater agility in adopting new technologies such as AI and cloud services. By aligning security initiatives with business outcomes—such as protecting brand reputation, ensuring continuity of operations, and enabling secure innovation—CISOs are helping their firms thrive in an era where digital risk is inseparable from business success.
Conclusion
The 2025 CISO report paints a picture of a role in flux, shaped by the rapid advancement of AI, the intensifying threat landscape, and the rising expectations of executives and regulators. While CISOs grapple with expanded duties—including AI governance, secure software development, and personal accountability—they are responding with strategic investments in talent, collaborative risk management, and business‑focused communication.
