We're redefining “zero-trust.”

When legacy identity security companies say “zero-trust,” they often really mean “trust our software, hardware, and company to be free of vulnerabilities and insider threats.”

When we say “zero-trust,” we mean it. Our platform leverages patented post-quantum cryptographic techniques to bring mathematically-provable security to complex modern applications. As long as the laws of mathematics don't fail, your security won't either.
