We've all heard the warnings that attackers are using sophisticated #agenticAI to breach organizations faster than ever. It's largely a myth. Catch Tenable CPO Eric Doerr at #HumanX as he cuts through the hype on how attackers are actually using #AI. @HumanXCo #ExposureManagement #Cybersecurity

8 years running: Tenable is ranked first in worldwide market share in the @IDC Worldwide Device Vulnerability and Exposure Management Market Shares, 2025 report. We believe that as AI-enabled attackers accelerate, our #agenticAI advancements are helping customers stay ahead.

#AI models are great at reasoning, but they don't automatically understand your unique environment. Tenable Hexa AI closes that gap with an "agentic harness," a governance layer that limits what AI can see and do, determines when a human needs to approve changes, and records every action for an audit trail. Take a look inside how we built it.
