On Thursday, July 9th at 9 AM Pacific / 12 PM Eastern, Office Hours will host [Sunil Agrawal](https://www.linkedin.com/in/sunilcagrawal/), CISO at Glean, for a conversation on what security readiness looks like now.

We'll talk about :

- AI compresses the time required to understand a target, map the attack surface, and personalize the first move.
- The grammar, tone, and context clues that once revealed attacks are disappearing.
- Deepfake calls and synthetic media change the control plane for approvals, payments, and trust.
- Security teams will need new processes, tools, and organizational muscle to respond at the pace of model-driven attacks.

**The format.** 15 minutes online. One topic. Call-in questions live. No slides. No pre-written questions. Just a real conversation.
