Quantum computing will eventually weaken widely used public-key cryptography. Standards bodies have published post-quantum algorithms, and regulators are encouraging organisations to plan their migration. For most firms, the hardest part is not the new algorithms — it is knowing where the old ones are.
Cryptography is everywhere
Certificates, libraries, protocols, hardware and third-party services all embed cryptographic choices. Much of it is invisible in day-to-day inventories.
The same discipline applies
Post-quantum migration is, in effect, a very large remediation programme. It benefits from exactly the same approach as vulnerability management:
- Discover where quantum-vulnerable cryptography is used.
- Understand context — which systems protect long-lived or sensitive data, which are exposed, which are critical.
- Prioritise by real risk, not by a blanket deadline.
- Fix with governance — tested, approved and verified changes, with evidence.
Ready for what comes next
QsecurityAI's governed engine is being extended to discover quantum-vulnerable cryptography and support migration to post-quantum standards — so the workflow you use for today's vulnerabilities is ready for tomorrow's.
