- Certes DPRM
Best for: Companies protecting sensitive data in transit
Certes DPRM covers a narrower job than the rest of this list, because it protects data in transit with quantum-safe encryption instead of finding or rebuilding your cryptography. That suits companies of any size that want sensitive traffic, including Active Directory, protected while the wider migration goes on. Its listing does not name the NIST algorithms it uses, so ask before you count it toward a NIST plan.

- Post-Quantum Quantum Safe Platform
Best for: Enterprises needing quantum-safe VPN, messaging, and identity in one suite
The modular architecture covering identity, VPN, and messaging in one platform is convenient but also means you are buying a suite rather than best-of-breed components. If you only need quantum-safe VPN, you are still buying into the broader platform. The backward compatibility with legacy infrastructure and hybrid classical and post-quantum approach means you do not have to rip and replace existing systems, which is the right design for any realistic enterprise migration.
