AI Broke Your Security Model.

We Built a New One.

Gray Swan is the adversarial evaluation solution trusted by leading frontier labs to assess their flagship models. That same intelligence powers the platform protecting enterprise AI agents in production.

Offense informs defense.

Every attack we run sharpens what we stop. Every attack we stop is one we've already run.

ADVERSARIAL RED-TEAMING

Find what breaks before someone else does.

Shade is the adversarial red-teaming solution built by the team that reliably breaks the latest models. Powered by LLM-based adversarial agents and available as automated software, Shade runs the attacks that work today against your model, your guardrails, and your deployment context. You see exactly where you're exposed, and exactly what to do about it.

Runtime Defense

Stop the attacks that actually work.

Cygnal is the runtime protection and monitoring solution trained on the attacks discovered through our security research team and global red-teaming network. It classifies and blocks adversarial inputs and unsafe outputs in production, with the lowest bypass rate against current-generation attacks — because it's tested against them every time the frontier moves.

They test for yesterday.
We test for tomorrow.

Most AI security validates against known attacks. Gray Swan tests against attacks discovered by 15,000+ adversarial researchers — most of which haven’t been published yet.

We discover threats first

Arena competitions reveal emerging attacks before they appear in public databases.

We test like real adversaries

Red-teamers have generated over three million attack attempts that drive our methods.

We defend what you actually deploy

Policies and scans adapt to your agent’s tools, data, and workflows rather than generic checklists.

Trusted at the Frontier

Our research has directly informed the safety evaluations of some of the most advanced AI models in the world.
