Building a Shield of Defensibility: How CISOs Can Protect Their Careers and Organizations

In today’s fast-evolving regulatory landscape, Chief Information Security Officers (CISOs) are under immense pressure. With increasing legal scrutiny, evolving SEC regulations, and rising personal liability concerns, CISOs must take proactive steps to safeguard both their organizations and their careers.

In a recent InformationWeek article, I discuss how CISOs can build a shield of defensibility to demonstrate due diligence, ensure regulatory compliance, and create a defensible position that mitigates both organizational and personal risks. Below is a short summary of the recommended approach.

The Three-Layered Shield of Defensibility

A shield of defensibility is built on three key layers.

1. Establishing a System of Record – A comprehensive management system of record ensures that all cybersecurity decisions, actions, and assessments are meticulously documented. This record serves as a critical audit trail—demonstrating compliance, accountability, and strategic decision-making.
2. Demonstrating a Duty of Care – CISOs must align their cybersecurity programs with recognized industry frameworks, such as NIST CSF or ISO 27001, while also conducting regular risk assessments, vulnerability scans, and control testing. These proactive measures help demonstrate that security teams are fulfilling their duty of care and adhering to regulatory requirements.
3. Communicating Cyber Risks in Business Terms – Cybersecurity is no longer just a technical issue—it’s a business imperative. Effective CISOs communicate cyber risks in a way that resonates with executives and board members, linking cybersecurity initiatives to business goals. Real-world cyber resilience exercises can help illustrate the tangible impact of cyber risks on operations and financial stability.

CISOs are increasingly held accountable for cybersecurity incidents, making it essential to build a strong defensive foundation. By implementing these three layers—a system of record, a structured cybersecurity program, and a strong communication strategy—CISOs can protect themselves and their organizations from regulatory and legal risks.
