As enterprises adopt AI agents, security risks like prompt injection, data exfiltration, and agent impersonation are rising fast. Traditional security tools weren’t built to handle these new, autonomous systems. That’s where Model Context Protocol (MCP) and Agent-to-Agent Protocol (A2A) step in.
While MCP and A2A don’t solve security challenges alone, they act as strategic control points where advanced security tools can plug in. MCP governs how AI agents securely access enterprise systems, while A2A manages secure agent-to-agent collaboration and identity verification.
Through real-world threat examples—like a malicious prompt hiding inside a support ticket or a fake agent trying to access internal tools—this post shows how MCP and A2A work together as part of a layered, defense-in-depth strategy.
Companies like Natoma are leading the way by building specialized security solutions that integrate with these protocols—offering identity governance, behavior analysis, and real-time protection for AI-driven operations.
In short: MCP and A2A are your foundation, but it’s the added layers that truly secure your AI ecosystem.
