Post-Quantum Cryptography addresses the near-term threat that quantum computers will break RSA and ECC encryption currently protecting TLS, VPNs, and PKI — a risk NIST has responded to by finalising its first post-quantum algorithm standards in 2024. Organisations holding sensitive data with long shelf-lives — defence contractors, financial institutions, and healthcare systems — must begin cryptographic agility programmes now to avoid 'harvest now, decrypt later' exposure.
