Composio introduces Firewall to check AI agent actions and information returned through Composio

Composio introduced Firewall on Oct. 22, 2026. Karan Vaidya says it checks agent actions and information returned through Composio, with each action evaluated using Jev and custom small language models. He says the tool is intended to enforce user and developer boundaries and protect against prompt injection. Composio shows an example of a blocked email result, not an independent test of its protection.
