Post-Quantum Cryptography (PQC) Migration Consulting

Prepare your organization for the quantum era. ThunderShield assesses your cryptographic infrastructure, identifies harvest-now-decrypt-later exposure, and plans a phased PQC migration to NIST ML-KEM and ML-DSA standards — before quantum threats become real.

PQC Migration Process

NIST-aligned post-quantum cryptography migration planning and implementation process

  1. Current-state inventory：Enumerate all cryptographic algorithms in use across systems, applications, and protocols to build a complete cryptographic asset register
  2. Risk assessment：Evaluate quantum threat risk by data sensitivity, longevity, and exposure surface to identify high-priority migration targets
  3. Migration planning：Develop a phased migration roadmap, selecting NIST-compliant PQC algorithms and hybrid transition approaches suitable for each system
  4. Implementation：Support technical teams in implementing PQC algorithms and integrating them into existing PKI, TLS, signature, and key management workflows
  5. Validation testing：Perform functional and security validation of migrated cryptographic components to confirm correct PQC implementation and interoperability

Frequently Asked Questions

What is Post-Quantum Cryptography (PQC)?

PQC refers to cryptographic algorithms designed to resist quantum computer attacks. NIST finalized ML-KEM and ML-DSA standards in 2024, and organizations should plan migration now to future-proof their data security.

Why do organizations need to plan PQC migration now?

Quantum computing is advancing faster than expected, and adversaries can already harvest encrypted data today to decrypt it once quantum computers mature (the 'harvest now, decrypt later' threat). Organizations protecting long-lived sensitive data should begin assessment and planning immediately.

How long does PQC migration take?

It depends on organization size and cryptographic complexity. A cryptographic asset inventory and risk assessment typically takes a few weeks, while full migration planning and implementation may span months to years. Starting early allows a phased, manageable approach.
