Proving Security in the Era of AI
AI is changing the speed, scale and stakes of cybersecurity. Security teams need to move beyond finding problems and reporting activities. They need to identify the exposures that matter most, prioritize what is actually exploitable, and prove that remediation reduced the risk.
Join us at the Proactive Security Summit where we bring together executive perspectives, practitioner insight, research and focused conversations to help modern organizations build a more proactive security program in the era of AI.

Agenda
OPENING KEYNOTE
The Proof Point: Proving Security in the Era of AI
Security leaders are being asked to show more than how much activity their teams completed. They need to demonstrate which exposures matter, what changed, and whether risk actually went down. This opening session frames the shift from assumptions to evidence and introduces a practical way to move from exposure to action to proof.

CLOSING FIRESIDE CHAT
The Board is Asking: How Do You Prove Security Works?
Security leaders need a clearer way to answer the questions that matter most to executives and boards: What is our real exposure? What are we doing about it? How do we know it worked? This closing conversation looks at the evidence, metrics, and operating practices that can turn security progress into a credible leadership story.
