Join Proofpoint CEO Sumit Dhawan and Chief Strategy Officer Ryan Kalember for an exclusive executive briefing on how frontier AI has changed the speed and economics of cyberattacks, and what CXOs must do now to stay ahead of it.

As frontier AI models such as Anthropic’s Claude Mythos compress the time between vulnerability discovery and exploitation, the assumption that defenses can rely primarily on patching and remediation no longer holds. The challenge for leaders is now broader and more urgent: how to reduce the greatest areas of risk across people, data, and AI while attackers move faster than traditional response cycles.

During this briefing, Sumit Dhawan will frame why this shift matters at the leadership level, and Ryan Kalember will discuss the technology and security implications for enterprises navigating this new reality.

You’ll learn:

  • Why frontier AI has collapsed the time between vulnerability discovery and active exploitation
  • Why reducing exposure matters as much as improving visibility and patching
  • Why protections across people, AI and data must match the speed of AI
  • The decisions and architecture choices CXOs should be making now
