Quantum software and post-quantum security, built to be checked
SoftQuantus is a European software company. We build QCOS, an operating layer for quantum research, and QuantumLock, a post-quantum service for signing, licensing and cryptographic inventory.
Every QCOS runtime call leaves a sealed record that anyone can recheck offline. Every offering we sell carries a lifecycle stage, so you know what is ready for production today.

What we do
Two problems, one discipline
Quantum computing and post-quantum cryptography are usually sold as separate futures. For our buyers they are one present-day question: can I trust this result, and will this signature still hold?
Quantum research that can be reproduced
QCOS runs quantum algorithms through one API, SDK, CLI and MCP server, and leaves a sealed record of every runtime call that reviewers can recheck without access to our systems.
Signatures that survive the quantum transition
QuantumLock finds quantum-vulnerable cryptography in your inventory, signs artifacts with ML-DSA alone or alongside a classical signature, and validates licences under both rules.
One way of working across both
Published formats, open verification tools and a public lifecycle for every offering.
How we work
Principles our buyers can hold us to
Evidence before claims
The figures on our verified results page state what was measured, on what, and where the evidence lives. When a result stops holding, we withdraw it in public.
Verified resultsA lifecycle on every offering
Production, available, preview, development or roadmap. The label tells you what you can rely on today.
Product lifecycleOpen standards
NIST FIPS 203, 204 and 205, CycloneDX 1.6, RFC 9162 Merkle trees and OpenAPI. Your outputs stay readable without us.

Work with SoftQuantus
Bring us the problem: a research workload that must be reproducible, or a signing and licensing estate that must outlast RSA and ECC.
