IdenQ

Post-Quantum Cybersecurity

We build cryptography that outlives the quantum threat.
Hybrid classical + post-quantum protection for the assets and identities that matter most.

IdenQ is a deep-tech security company from Spain working at the intersection of post-quantum cryptography, digital identity, and digital asset protection. Our multidisciplinary team brings together specialists in cryptography, bioengineering, security architecture, and Web2/Web3 engineering.

Our thesis is simple:

Everything encrypted today with classical algorithms can be harvested now and decrypted later, the moment a cryptographically relevant quantum computer arrives. Long-lived secrets — keys, identities, inheritances — need quantum-safe protection today, not on Q-Day.

So we build systems where hybrid encryption (classical + post-quantum), zero-knowledge proofs, and threshold access (no single party ever holds the full key) are the default, not an afterthought.

Post-quantum migration is too big a problem for closed doors. The whole industry has to re-key the internet in the next decade — and that only works in the open. As we grow, we're committing to publish and maintain open tooling in the field we work in:

• 🔎 Quantum-readiness scanning — tools that audit codebases and dependencies for quantum-vulnerable cryptography (RSA, ECDSA, static DH…) and map a migration path to PQC.
• 🧩 Hybrid-crypto building blocks — practical, well-documented reference implementations for combining classical and post-quantum schemes (KEMs, signatures, envelope formats) without foot-guns.
• 🕵️ Zero-knowledge identity patterns — proving who you are without revealing what you are: ZK-based verification flows for sensitive identity data.
• 📚 Knowledge base — engineer-friendly guides on PQC standards (FIPS 203/204/205), harvest-now-decrypt-later threat modeling, and crypto-agility, in English and Spanish.

Our open source principles:

• Security by transparency — cryptography you can't inspect is cryptography you can't trust.
• Standards first — we build on NIST PQC standards and open formats, not proprietary lock-in.
• Docs are part of the product — every project ships with threat models and honest limitations.

Time invested in building our quantum-safe stack, tracked with WakaTime:

We're just getting started in the open — and we'd love company on the way:

• ⭐ Watch this org to catch our first public releases.
• 🐛 Open issues on any public repo — bug reports, threat-model questions, and "have you considered…" are all welcome.
• 🔬 Security researchers: found something? Tell us privately first at idenq.io and we'll credit you — responsible disclosure always.
• 💬 Talk PQC with us — if you're migrating a system to post-quantum crypto and hit a wall, open a discussion. Sharing the scar tissue is the point.
