  • Policy-Driven Crypto-agility
As someone who implemented enterprise risk frameworks across DOE's complex infrastructure, I know PQC migration without orchestration is doomed to fail. Agencies need unified command and control, not scattered point solutions. This orchestration-first approach, demonstrated by QuSecure, is ideal for the complexities of federal environments today.

Four questions your migration plan has to answer

Start with one qualifier: do you have critical network-facing systems running legacy cryptography? Then ask these, in order.

How do you get to post-quantum key exchange on systems that cannot support it?

ML-KEM applies by policy on the connection itself, hybrid with classical key exchange during transition. The system behind it is not modified.

What is your strategy for TLS 1.3?

Encryptors carry any connection, including TLS 1.0 and 1.1 on systems that cannot be patched, over TLS 1.3 at the network layer. No recode, and no maintenance window for the application.

How do you move certificates and PKI?

Rotation is automated from the same console, ready for certificate lifetimes shortening to 47 days by 2029 and for post-quantum signatures when your CA issues them.

What happens when you have to do it again?

The question the others build to. Standards will move again after ML-KEM. A migration program answers that with another program; a policy engine answers it with a policy change.

Frequently asked questions

  • What does QuSecure's QuProtect R3 actually do?

    QuProtect R3 discovers the cryptography in use across a network, changes it to NIST post-quantum algorithms by policy at the network layer without application code changes, and generates a CycloneDX cryptographic bill of materials on demand.

  • Do I need to rewrite any code to make my applications quantum-safe?

    No. The change happens at the network layer. Encryptors carry connections over post-quantum TLS 1.3, so the algorithms a system negotiates change without modifying application source code or swapping cryptographic libraries.

  • Is QuSecure a quantum computing company or a security company?

    A security company. QuProtect uses NIST post-quantum algorithms implemented in software. It needs no quantum hardware and no quantum computer.

  • Which NIST post-quantum algorithms does QuSecure support?

    ML-KEM under FIPS 203, including ML-KEM-1024 for CNSA 2.0 alignment; ML-DSA under FIPS 204; SLH-DSA under FIPS 205; and hybrid post-quantum TLS via X25519MLKEM768.
