What is Phio TX®?
Phio TX® is a key management system that makes today’s encryption quantum safe and enables a seamless transition to the latest Post-Quantum Cryptography (PQC) standards.
Its modular architecture enables a seamless integration into existing network infrastructure, resulting in minimal disruption to ongoing operations, no network performance degradation and no downtime due to crypto upgrades.
Why Phio TX?
- Mitigate quantum attacks: a strong symmetric key is created and travels out-of-band, independently from the encrypted data. This separation of the keys from the data protects against quantum and other attacks (HNDL, man-in-the-middle).
- No stolen keys: Ephemeral key pairs are dynamically generated in memory/deleted after use. Eliminate security risks from static, pre-shared, or private keys stored on endpoints or somewhere in the network.
- NIST Validated: Only vendor to be FIPS 203 and FIPS 140-3 validated. Utilizes NIST Entropy Source Validation for unpredictable randomness for secure data transmission, eavesdropping prevention.

Dynamically stack, switch, mix, deliver, and manage quantum-safe keys across any network media type, anywhere on the planet, with no network interruptions or downtime.
NO bumps in the wire. NO latency. NO new hardware on the critical path.
Leveraging quantum entropy, all NIST-backed PQC algorithms, and a second symmetric key delivered out-of-band, Phio TX removes single points of failure common to modern-day encryption practices while future-proofing your crypto infrastructure for the quantum era. See how Phio TX leverages the five essential characteristics of next-gen cryptographic security.
