Our Story

Security was built for the world before AI. We're building the one that comes after.

AI is now an actor inside every enterprise. Zaun secures both sides of it: the AI your team adopts, and the operations that defend you at machine speed.

§ A2The next era

A new era of security, sector-creating by design.

Zaun is built on a simple bet: security gets better when it fits the environment it's protecting, and when the people running it have time to think.

So we listen to your data in place. We write detection logic and runbooks for your exact stack, in plain English, reviewed by the engineers who own the response. We keep humans in the loop because automation without judgment is how things go wrong.

We want the incentives to line up with yours. Our job is to make your program quieter, sharper, and easier to trust. Programs like this take time to build. The detections get more specific. The response gets cleaner. Trust grows from there.

01

Coverage that scales

Every system, every identity, every agent. Listened to in place, with no ingest tax and no centralization tax.

02

Authored by AI, read by humans

Detection logic and runbooks written for your exact stack, then reviewed in plain English by the engineers who own the response.

03

Faster than the threat

Adversaries automate, so we automate alongside them. Detection compresses from quarters to weeks, and response from hours to minutes.
