Protecting Agents with Cisco AI Defense and Google Agent Development Kit

Agents are powerful because they do more than answer questions. They call tools, retrieve context, and act across multiple steps. That is what makes frameworks like Google’s Agent Development Kit (ADK) so useful, and it is also what changes the security problem. Cisco AI Defense provides runtime protection for AI agents. With this integration, AI Defense now plugs into Google’s ADK and carries the same runtime controls from local development to Agent Runtime on Gemini Enterprise Agent Platform.

Google’s ADK is used to build tool-using agents. Agent Runtime is the managed runtime to deploy them. This integration makes it easy to keep Cisco AI Defense runtime protection attached in both places.

The security problem changes with agents

The real risk is not just that an agent produces a bad answer. The bigger issue is that untrusted prompt content can influence tool behavior, and tool output can send sensitive data back into the model. Once agents start interacting with…
