Fluency is a cryptographic infrastructure company.

We build platforms that keep critical systems operating during network outages, power failures, cloud disruptions, and adversarial attacks, where continuity isn't optional.

Our core technology, the Virtual Secure Element (VSE), replaces hardware trust anchors (HSMs, TEEs, secure elements) with a fully software-defined cryptographic engine: post-quantum resilient, infrastructure-free, and deployable on any device - from drones and satellites to edge nodes and mobile platforms.

We serve governments, critical infrastructure operators, national security actors, and major financial institutions. Our partners and appointments include the European Central Bank, Mastercard, and U.S. Government agencies. Fluency is a member of the Bank of England AI Consortium.
