Agent Firewall

An agent firewall applies policy to what AI agents do, not only what they say. It checks every tool call on the way out and scans what the tool sends back before the agent reads it.

Also known as: AI agent firewall, tool-call governance

Why agents need it

Agents act on their own, at machine speed. A prompt check alone misses the tool calls, and the data that comes back from tools can carry personal data into the agent’s context.

In Raidu

Tower’s Agent Firewall puts every message and every tool call through the same policy stack. It ships 473 prebuilt tool templates across 33 categories, plus your own. Policy sets are configured per agent and per organisation; a call outside the allowed set is blocked and logged, and every step of the call chain is written to the tamper-evident record in order.

Common questions

Questions about Agent Firewall.

Is the tool output checked? +
Yes, for personal data, before it reaches the agent.
Can we restrict which tools an agent can call? +
Yes. A call that does not match the allowed set is blocked and the decision is logged.
