TL;DR: Quantum-safe migration is already a live planning problem because data with long confidentiality lifetimes may be harvested now and decrypted later, and the article argues that inventorying cryptographic assets, mapping protocol use, and aligning vendors and standards are now prerequisite steps, according to SSH Communications Security. The real challenge is governance: PQC migration exposes where infrastructure, firmware, and embedded encryption assumptions outlast the controls meant to manage them.
Editorial analysis by NHI Mgmt Group, based on content published by SSH Communications Security: “From Urgency to Action: Why Post-Quantum Cryptography Can’t Wait”.
Key questions
A: Start with the links that carry long-lived sensitive data and high-value administrative traffic, then use hybrid cryptography where classical and post-quantum methods can coexist.
Q: Why do embedded systems make PQC migration harder?
A: Embedded systems are difficult because their encryption may be hard-coded into firmware or hardware, leaving no simple patch path.
Q: When should security teams prioritise PQC work over other cryptographic projects?
A: Prioritise PQC when the organisation holds data that must stay confidential for years or decades, or when critical systems depend on encryption that cannot be easily upgraded.
Practitioner guidance
- Build a cryptographic asset inventory Catalogue where encryption is used across applications, protocols, certificates, devices and firmware so migration scope is visible before any algorithm change is planned.
- Map hard-coded and embedded dependencies Identify hardware-level encryption, embedded firmware and fixed libraries that cannot be upgraded in place, then separate them from software-only remediation paths.
- Review vendor PQC roadmaps Check whether critical suppliers, managed platforms and appliance vendors have credible post-quantum plans, because their readiness becomes part of your own control timeline.
Bottom line: Post-quantum migration is not only a cryptography upgrade. It is a governance exercise in finding every place where identity, trust and encryption intersect.

Cryptographic migration is an asset-governance problem before it is an algorithm problem: organisations fail when they treat PQC as a standards swap instead of a discovery exercise. Encryption exists in protocols, code, embedded devices and vendor systems, which means the real control boundary is inventory and dependency mapping. The practitioner conclusion is simple: if you cannot locate the cryptographic estate, you cannot govern the migration.
A question worth separating out:
Q: What are the signs that an organisation is not ready for quantum-safe encryption migration?
A: A common warning sign is that the organisation cannot say where encryption is used, which assets depend on it, or which systems would break if algorithms changed. Another indicator is the absence of a migration roadmap, test plan, or maintenance cycle for cryptographic updates. If discovery is incomplete, readiness is still mostly aspirational.
