The suite

Two products.
One quantum-resistant stack.

FIPSign covers the two layers that matter most: what you sign and how you transmit it.

Signing & Certificates
PQ-Sign
ML-DSA-44/65/87 · NIST FIPS 204

Post-quantum signing as a service. Sign tokens, issue certificates, and verify identities — choose ML-DSA-44, ML-DSA-65, or ML-DSA-87 per project. No key management, no infrastructure. Get an API key and call /sign in minutes.

Sign any entity — users, orders, devices, documents
Private CA — issue ML-DSA-65 certificates (PQCert & X.509)
JS/TS SDK · Python SDK · MCP for Claude
Mandate — bounded authorization for agents, devices & microservices
10,000 free tokens/month — no credit card

TLS Proxy
PQ-Proxy
X25519MLKEM768 · TLS 1.3

Post-quantum TLS reverse proxy — available as a managed cloud service or self-hosted on your own server. Every connection is automatically protected with X25519MLKEM768. No code changes to your backend.

Automatic Let's Encrypt certificates per domain
Any backend — cloud, on-premise, serverless
Real client IP forwarding · connection metrics
Cloud SaaS · On-Premise self-hosted

Both products implement NIST-standardized post-quantum algorithms — finalized August 2024. No custom cryptography. No experimental algorithms. The same standards that governments and financial institutions are migrating to.

The threat

Classical security
has an expiry date.

Every signature and TLS handshake made with classical algorithms today is vulnerable to a sufficiently powerful quantum computer. The migration window is now.

⚠️
ECDSA, RSA & classical TLS are broken
JWT (RS256/ES256), OAuth tokens, standard TLS handshakes — all rely on algorithms that Shor's algorithm breaks efficiently on a quantum computer.
VULNERABLE
🎯
Harvest now, decrypt later
Nation-state actors are already recording encrypted traffic and signed data today — to forge or decrypt it once quantum computers are available. The threat is active now, not in the future.
ACTIVE THREAT
📅
Migration takes years
NIST finalized the post-quantum standards in August 2024. Companies that migrate now will have compliance locked in before the audit — those that wait will be scrambling. The window to migrate cleanly is open now.
ACT NOW
Who it's for

Built for developers.
Designed for companies.

You don't need a security team or a cryptography background. If you can make an HTTP request, you can be quantum-resistant today.

⌨️
For developers
REST API, JS/TS SDK, Python SDK, MCP for Claude. Integrate in minutes. No crypto expertise — we handle the key management, algorithm selection, and certificate infrastructure.
✓ Production in under 5 minutes
✓ No infrastructure to deploy or maintain
✓ Works with any backend — cloud, on-premise, serverless
✓ Open source SDKs — read exactly what's sent to the API
🏢
For companies
No security team required. No cryptography expertise. No sales call. If your company handles sensitive data, financial transactions, or regulated information — post-quantum protection is no longer optional.
✓ NIST FIPS 204 compliance out of the box
✓ No dedicated security team needed
✓ Protect existing backends without code changes
✓ Audit-ready — algorithm, key management, compliance handled

Start quantum-resistant
today.

No sales call. No contract. No cryptography expertise required. Pick the product you need — or use both.
