Security Without Compromise
Five security disciplines. One methodology. Every engagement staffed by senior offensive engineers - winners of 30+ international competitions - directing rigorous manual review and frontier AI models as force multipliers. 300+ engagements across $120B+ in protected digital assets. Zero client exploits.

Two Independent Teams. Rigorous Review. Frontier AI. Every Engagement.
Our team members are winners of 30+ international competitions, responsible for discovering critical vulnerabilities in industry-leading projects, and trusted to secure over $120 billion in digital assets.
Every engineer does rigorous manual review and directs frontier AI models as a force multiplier - extending code coverage, generating adversarial test cases, and reasoning about complex systems at a depth and pace that manual-only or automated-only approaches cannot match. Hexens deploy two such teams to every engagement in parallel. Findings are cross-verified, ensuring depth, breadth, and reassessing the blind spots.

Tailored Scoping Led by Senior Experts
Your engagement begins with a strategy session led by the same security researchers who will oversee the audit. We align on your system design, threat model, and specific risk profile - not a generic checklist.
[03.]
Beyond Scope, Beyond Standard.
Hexens deliver more than expected. Post-remediation retesting is always included, and we routinely identify critical out-of-scope issues - the result of a holistic approach where engineers understand your full architecture, not just the files in scope.
