PortSwigger

Burp AT: agentic AI that thinks like a pentester, with the tools of a pentester. A professional pentest takes more than a capable model. Burp AT brings agentic AI to human-led pentesting, natively inside Burp Suite. Agents pursue the tasks you give them using Burp’s battle-hardened tools, project context, and purpose-built skills developed with PortSwigger Research.

Harmonic Security

Learn how enterprises are really using GenAI (and why policies alone aren’t enough to keep data safe). I recently spoke with Alastair Paterson, CEO and co-founder of Harmonic Security. In this video, we explored real examples of risky AI use, discussed why traditional DLP tools often fall short, and showcased Harmonic’s enables real-time, context-aware protection without slowing teams down. If security teams are going to embrace AI adoption, these are exactly the kind of controls they need.
