Is a context firewall like a WAF for AI agents?

A web application firewall (WAF) protects web apps from HTTP and application-layer attacks such as injection, XSS, and malicious requests. A context firewall protects agent workflows from a different failure: untrusted context — documents, memory, tool output, MCP responses — crossing into a privileged action. The name rhymes; the boundary is different.

TL;DR
  • A WAF guards the web app perimeter against HTTP-layer attacks.
  • A context firewall guards the agent workflow against context-to-action abuse.
  • Different layer, different threat model.
  • A WAF won't see an agent authorize a bad tool call.

Perimeter vs agent loop

A WAF inspects requests to your application. It has no view into whether an agent let a retrieved document trigger a tool call or memory write. That is the boundary a context firewall governs.

Frequently asked questions

Does a WAF protect AI agents?
Only at the web perimeter. It does not control context authority inside the agent loop, so it cannot stop untrusted context from driving a privileged agent action.
