PQShield UltraPQ-Suite is a commercial post-quantum cryptography solution by PQShield. ZeroTier Quantum is a commercial post-quantum cryptography solution by ZeroTier. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about each one.
Best for: Product makers building PQC into chips and software
PQShield is here for the build side of the move, because it gives your engineers the libraries, chip IP and firmware to ship NIST algorithms in their own products. That fits companies making devices, chips or embedded systems more than teams that need to find and replace cryptography in-house. Ask which form fits your roadmap, whether that is software, IP cores or a firmware upgrade for devices already in the field.

Best for: Distributed teams needing quantum-safe overlay networking across mixed environments
The trade-off is that ZeroTier Quantum is not a cryptographic management platform. It does not give you a CBOM, compliance reports, or a migration workflow for your existing PKI. It secures the network layer going forward. Teams that need to address the harvest-now-decrypt-later threat for data already in transit should pair this with a cryptographic inventory solution. For greenfield deployments or teams building new distributed infrastructure, ZeroTier Quantum is one of the more operationally straightforward ways to get post-quantum network security in place.
