A firewall for the agentic era.

For fifty years, software behaved the way it was written to behave. We governed it at build time — code review, access controls, change management — because its behavior was fixed before it ever ran. Agents break that assumption. They generate their behavior at runtime, choosing which tool to call and with what arguments in the moment. When software writes itself as it runs, the layer that governs it has to run there too.

That layer barely exists yet. The industry is racing to build everything else around agents, and the security tooling is consolidating fast: Lakera went to Check Point, Prompt Security to SentinelOne, Aim Security to Cato Networks, Protect AI to Palo Alto Networks, Promptfoo to OpenAI, all in roughly twelve months. Strathon’s bet is that this one layer has to be open-source. It is the component that decides what your agent is allowed to do — and trusting a black box you cannot inspect to make that decision is the same mistake as trusting the agent itself. So Strathon is a firewall you run yourself, read every line of, and never lose access to.

The product is a firewall that sits between your agent and its tools, evaluates every call against policies you control, and blocks the dangerous ones before they execute, in under a millisecond, inside your agent process. It works with any framework, and self-hosting is free forever.
