The systems that matter most are the ones nobody will touch
- Challenge
- You have high-value assets and a hard deadline to upgrade them to PQC. Rip and replace will not get you there on time or on budget, and some of your most critical systems cannot be upgraded at all.
- QuProtect
- QuProtect changes the cryptography without changing the systems. Software only, no new hardware, and nothing you already run gets replaced. Compatible with legacy systems and in air-gapped environments.
- Challenge
- Discovery-only tools left you with an overwhelmingly long (or underwhelmingly short) list of assets, with no path to prioritization or remediation.
- QuProtect
- QuProtect discovers and secures data-in-transit, because source code tells you what an application might negotiate and the network tells you what it did negotiate. It prioritizes policy violations by severity, and remediates them in the same platform.
- Challenge
- You spend a fortune upgrading your cryptography, and in a few years, with rapidly advancing AI and quantum technologies, you have to do it all again.
- QuProtect
- Lightweight sensors and encryptors form a service mesh, controlled by a central orchestrator. The next algorithm change becomes a simple configuration change, not a years-long migration.
How it works
Three pillars under one Orchestrator. Discovery feeds remediation, and remediation is what the reporting proves.
-
Discovery
QuProtect Recon
Find where legacy cryptography is still in use, on live network traffic, ranked by exposure rather than by count.
Cryptographic discovery and inventory
-
Remediation
QuProtect Resilience
Change what those systems negotiate, by policy, without code changes.
Crypto-agility and remediation
-
Compliance
QuProtect Reporting
Produce the audit-ready CycloneDX CBOM your auditor asks for.
CBOM and compliance
Prioritize by policy
-
An administrator sets a policy in the Orchestrator: which algorithm, and where it applies.
-
The Orchestrator distributes that policy to every encryptor in scope.
-
Encryptors renegotiate connections on the new algorithm while traffic keeps flowing.
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.
Validated in production
Live post-quantum sessions over legacy satellite links, on endpoints that could not be modified. CNSA 2.0 readiness proven to auditors in one quarter, starting with no inventory. Three customers have published the detail.

Banco Sabadell
Banco Sabadell validated post-quantum TLS on customer-facing infrastructure in four months, and the SEC cited the pilot as an industry benchmark.

Global Telco TLS Migration
A Tier-1 operator deployed post-quantum TLS across existing infrastructure without rewriting legacy applications, against years of cryptographic debt.

-
Oil & Gas Critical Infrastructure
A multi-national oil company validated post-quantum encryption for exploration data in a production-equivalent environment, covering geological surveys that stay commercially sensitive for 20 years and SCADA systems with no application-level migration path. The pilot won production approval and a multi-year rollout budget.
Read the case study
“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.”
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.
