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
