Post-quantum cryptography consulting

Your encryption has an expiry date.

QuanMind finds every place your organization relies on RSA and elliptic-curve cryptography, ranks what a quantum computer would break first, and moves you to NIST-standard algorithms without stopping the business.

The threat

Harvest now. Decrypt later.

Adversaries are already copying encrypted traffic and archives. They don't need a quantum computer today. They need one before your data stops mattering.

A cryptographically relevant quantum computer could break today's public-key encryption in a fraction of the time classical machines need. Anything with a long shelf life is exposed now: health records, contracts, intellectual property, state secrets, identity credentials.

Are you already late?

Medical records, mortgages and IP often need 10 to 25 years.
Large enterprises typically plan for 5 to 10 years end to end.

Cryptographic posture assessment.

You can't migrate what you can't see. Our assessment builds a complete picture of the cryptography running across your estate, finds the weak points a quantum attacker would target, and hands you concrete, prioritized actions.

It's the foundation for choosing the right post-quantum algorithms, sequencing the migration around business priorities, and putting governance in place that keeps data protected.

INVENTORY

See every key.

Automated discovery across networks, code, certificates and hardware, combined with interviews where tools can't reach.

  • TLS endpoints and certificate chains
  • Source code, libraries and binaries
  • HSMs, KMS and vendor appliances
  • Cryptographic bill of materials (CBOM)
ANALYSIS

Rank the risk.

Each asset is scored by algorithm strength, data sensitivity, shelf life and how hard it is to change.

  • Quantum-vulnerable algorithm mapping
  • Harvest-now exposure by data class
  • Third-party and supply-chain dependencies
  • Crypto-agility gaps
ACTION

Know what's next.

A prioritized plan your security, engineering and leadership teams can all act on, with quick wins up front.

  • Board-ready risk summary
  • Algorithm selection guidance
  • Sequenced remediation backlog
  • Governance and ownership model

Standards we build on

The algorithms are ready.

NIST published its first post-quantum standards in August 2024, and in June 2026 the White House turned them into deadlines. Federal agencies now have dated milestones, and contractors are next.

FIPS 203

ML-KEM

Module-lattice key encapsulation, derived from CRYSTALS-Kyber. Replaces RSA and ECDH key exchange.

Use: TLS, VPN, messaging, key wrapping
FIPS 204

ML-DSA

Module-lattice digital signatures, derived from CRYSTALS-Dilithium. The general-purpose replacement for RSA and ECDSA signing.

Use: certificates, authentication, documents
FIPS 205

SLH-DSA

Stateless hash-based signatures, derived from SPHINCS+. Conservative security that relies only on hash functions.

Use: firmware, long-lived roots of trust
2024NIST publishes FIPS 203, 204 and 205
2026EO 14412 and OMB M-26-15 set binding federal migration deadlines
2030Federal high-value systems move key establishment to PQC; TLS 1.3 required
2031Digital signatures on those systems move to PQC
2035Remaining federal systems migrated; quantum-vulnerable algorithms disallowed
