Post-Quantum Cryptography (PQC) Inventory & Migration Consulting

ThunderShield's PQC platform scans live endpoints, packet captures, source code, and certificates to build a CycloneDX 1.6 CBOM crypto inventory, classifies quantum risk against NIST FIPS 203/204/205 and Taiwan FSC guidance, and delivers a prioritized migration plan — before harvest-now-decrypt-later attacks pay off.

PQC Migration Process

CBOM-driven post-quantum cryptography inventory and migration process aligned with NIST standards and Taiwan FSC guidance

  1. Multi-source inventory scan：Combine network endpoints, PCAP traffic, source code, and certificate/key files into one comprehensive cryptographic asset register
  2. Quantum-risk classification：Classify every finding CRITICAL, HIGH, MEDIUM, or LOW against policy standards, weighting internet-facing and harvest-now-decrypt-later-sensitive services
  3. Dual-axis prioritization：Assign P1–P4 remediation priority on a quantum-risk × migration-difficulty model, aligned with FSC migration guidance
  4. Compliance assessment & reporting：Assess against NIST FIPS 203/204/205 and Taiwan regulatory guidance, producing a Traditional-Chinese PDF report with a phased migration plan
  5. Migration support & re-scan：Support adoption of ML-KEM, ML-DSA, and hybrid transition architectures, then re-scan after migration to verify risk items are resolved

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.
