## Our take

What our shortlists say about the one we picked.

### [ZeroTier Quantum](https://cybersectools.com/tools/zerotier-quantum)

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.
