Reimagining Third-Party Risk in an Agentic AI World

Third-party risk is no longer a secondary concern. It has become the primary threat vector for enterprise compromise.

Q4 marked a structural inflection point: Attackers stopped targeting enterprises directly and instead exploited trusted vendors, open-source maintainers, SaaS integrations, and AI platforms – often without triggering immediate detection. The result? Silent exposure, cascading outages, regulatory fallout, and brand damage that boards are now feeling firsthand.

Traditional TPRM models – static questionnaires, annual reviews, and trust-based reporting – were not built for this reality.

Why this matters now:

  • AI accelerates risk while creating new blind spots in vendor oversight
  • Open-source ecosystems now behave like critical infrastructure
  • SaaS and API trust chains enable lateral compromise at machine speed
  • Vendor patching and remediation have become operational risk events
  • Insurance is retreating, shifting exposure back to the balance sheet

The question is no longer “Do we trust our vendors?” It’s “Do we have real-time visibility, verification, and resilience when they fail?”

In this live session, we’ll explore:

  • How agentic AI is reshaping supply chains and third-party trust assumptions
  • Why vendor criticality must be measured by blast radius, not contract size
  • What “continuous assurance” actually looks like in practice
  • How CISOs are adapting governance, identity, and incident response models now
