Third-Party Risk Management and Governance Challenges for CISOs

CISOs are increasingly confronted with the complexities of third-party risk management, as reliance on a vast ecosystem of external vendors and SaaS providers exposes organizations to significant operational and security risks. The challenge is compounded by the growing number of cyberattacks targeting third-party software, such as the incident involving APT29's attack on TeamViewer, which highlights the vulnerability of widely used remote access tools. Effective risk management requires not only identifying and monitoring these external dependencies but also ensuring transparency and accountability throughout the software supply chain.

In parallel, the evolving landscape of digital trust—exemplified by the shortening of TLS/SSL certificate lifespans to 47 days—demands that organizations treat certificate management as a critical business continuity function rather than a routine IT task. Governance and risk management frameworks must adapt to these operational realities, emphasizing proactive decision-making, clear accountability, and automation readiness to prevent outages and maintain resilience. CISOs must align security strategies with business objectives, ensuring that risk ownership and governance are embedded at every level of the organization.
