Quantum-Safe Isn’t Enough: Why Post-Quantum Cryptography Must Be Part of Defence in Depth
Post-quantum cryptography (PQC) will play an important role in protecting organisations against future cybersecurity risks associated with quantum computing. However, replacing vulnerable cryptographic algorithms alone will not make an organisation secure. PQC introduces cryptographic approaches designed to resist attacks from quantum computers. It does not determine who should access sensitive information, prevent malware, or stop authorised accounts from misusing data.…
