Perfai

Mythos + Perfai = complete app security.

App security has two layers: code and runtime. Mythos owns the code layer — injection, secrets, IaC misconfigurations, CVE variant chains, and pre-merge gating. Perfai owns the runtime layer — access controls, privilege abuse, shadow functionality, and multi-tenant isolation.

A typical app has 30,000+ permission combinations across workflows, endpoints and roles. Perfai sees the live app with a vision model, maps every permission boundary, and tests every combination with adversarial requests — then ships fixes back to your developers.

Mythos tells you your code is clean. Perfai tells you all 30,000 permission combinations are enforced correctly. You need both to be true.
