Cisco A2A Scanner
Open-source scanner for Agent-to-Agent protocol security vulnerabilities.
What it does
An open-source scanner from Cisco AI Defense for analysing Agent-to-Agent (A2A) protocol implementations for security vulnerabilities. Scans multi-agent communication patterns for misconfigurations and exploitable weaknesses.
Security relevance
As A2A becomes the standard protocol for multi-agent communication, scanning for vulnerabilities in these connections is critical. Checks authentication, authorisation, message integrity, and trust boundaries between agents.
When to use it
Use when deploying multi-agent systems that use A2A protocol. Requires understanding of agent communication architectures and the A2A specification. Essential for any production multi-agent deployment alongside the A2A Protocol standard.
OWASP coverage
Risks addressed — mapped to both OWASP Top 10 standards. 2 in LLM, 2 in Agentic.
