About ZeroTier
ZeroTier is a software-defined networking platform that connects people, devices, and clouds. The homepage describes it as covering cloud, IoT, and distributed systems, and it lists defense, manufacturing, and government among the sectors it serves.
The homepage describes ZeroTier Quantum, a version built for regulated organizations moving to post-quantum cryptography. It states that the product implements the CNSA 2.0 algorithm suite and can be deployed fully in air-gapped environments. The homepage also says the platform can run on existing servers, routers, and devices, and that the Central management service has two versions depending on when an account was created. Performance and security claims on the homepage are the vendor's own statements, and the customer testimonials shown there have not been independently verified.
