A CXO BRIEFING

Claude Mythos and the
New Attacker Timeline

Watch the on-demand recording of this executive briefing featuring Proofpoint CEO Sumit Dhawan and Chief Strategy Officer Ryan Kalember, where they explore how frontier AI is reshaping the speed and economics of cyberattacks—and what CXOs must do to stay ahead.

Frontier AI models such as Anthropic’s Claude Mythos are compressing the time between vulnerability discovery and exploitation, challenging the long-held assumption that defenses can rely primarily on patching and remediation. As attackers move faster than traditional response cycles, organizations must rethink how they reduce risk across people, data, and AI.

In this session, Sumit Dhawan outlines why this shift demands attention at the leadership level, while Ryan Kalember breaks down the technology and security implications for enterprises navigating this new reality.

In this on-demand recording, you’ll learn:
  • How frontier AI is collapsing the time between vulnerability discovery and active exploitation
  • Why reducing exposure is now as critical as improving visibility and patching
  • Why protections across people, data, and AI must operate at AI speed
  • The key decisions and architectural choices CXOs should be making now
