Cisco AI Defense, open-sourced the A2A Scanner, a tool designed to secure Agent-to-Agent (A2A) protocol ecosystem. It helps validate agent identity, detect spoofing and prompt injection risks, and includes modular analyzers that anyone can extend or customize. If you are exploring agentic AI frameworks or building multi-agent systems, we would love feedback, contributions, and critique from the community.
