Is Finance sector PQC Quantum Proof? Cyber Program & PQC
Verdict
Financial institutions should treat PQC as multi-year operational risk: inventory, third parties, market infrastructure dependencies, and board reporting. Not quantum-proof until classical public-key dependencies are migrated or accepted with residual risk.
Overview
Banks and fintechs already run strong control frameworks; add crypto inventory and HNDL for customer and market data.
