Arqit Encryption Intelligence is a commercial cryptographic inventory & crypto-agility solution by Arqit. PQShield UltraPQ-Suite is a commercial post-quantum cryptography solution by PQShield. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about the one we picked.
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.
