Cisco Principal Engineer's Fix for AI Code Security

Your AI coding agent learned from millions of lines of code, including insecure ones. That means by default, it can write vulnerable code too.

So how do you fix that?

John Groetzinger, Principal Engineer at Cisco, built CodeGuard, a security skills layer that teaches coding agents how to write and review code securely. He tested it against real scenarios.

The result:
84% success rate vs 47% baseline. Nearly 2× improvement.

In this episode we get into:
• how CodeGuard works
• why Cisco open sourced it
• the surprisingly simple method that gets agents to fix their own mistakes
