After decades of experience in military and critical infrastructure systems, our founder Carl Hendrix set out to build something radically better. The result was P55 Nexus: a dynamic security engine that replaces static secrets with short-lived, self-validating keys.
our mission
To replace static authentication with deterministic, verifiable trust, everywhere it matters.
We build systems that verify instead of assume, adapt instead of rely, and eliminate the weaknesses attackers exploit.
With no stored secrets, no trust chains, and no reuse, DynaKey and the P55 platform represent a new approach to digital security, built for performance, integrity, and future resilience.
