Offense, run the way an adversary actually runs it.
Cyrion is built by operators who spent a decade on both sides of the engagement table, running red teams and cleaning up after real breaches. We started Cyrion because point-in-time pentests could not keep pace with how fast production environments change.
Traditional penetration testing gives you a snapshot: a report, once or twice a year, describing what a small human team found in a fixed window. Attack surfaces don't sit still. New endpoints ship weekly, LLM features ship daily, and adversaries probe continuously. The gap between the last pentest and the next incident is where breaches happen.
Cyrion closes that gap with a swarm of offensive-AI agents that reason about your environment the way a skilled human red teamer would, chaining low-severity findings into demonstrable attack paths. They run continuously, at machine speed, with every exploit candidate validated in a sandbox before it's reported.
We don't sell a scanner. We sell a standing red team that never goes home.
Every finding Cyrion reports is a reproducible exploit, not a signature match, with the evidence trail auditors and engineering teams both need.
What we hold
ourselves to.
Adversarial rigor
We test the way attackers actually operate: chained, opportunistic, and unconcerned with your architecture diagrams.
Auditor-ready evidence
Every finding ships with reproduction steps, request logs and remediation guidance, not a severity score with no proof.
Autonomous, not reckless
Exploit candidates are validated against a sandbox replica before anything touches production. You control the blast radius.
Built by operators
Our team has run engagements against Fortune 500 and high-growth startups alike. We build the tool we always wished we had.
How we
got here.
Founded by a group of offensive-security engineers frustrated with scanner false-positive rates and stale annual pentests.
Shipped the first agent swarm capable of autonomous recon-to-exploit chaining against staging environments.
Extended coverage to LLM and agentic-AI surfaces as customers began shipping production AI features faster than they could review them.
Building toward SOC 2 Type II and expanding the swarm to continuous cloud-configuration testing.
The team.
A small founding group, with senior seats still open.
We're hiring across research, engineering and go-to-market.
