TL;DR: Governments are urging a shift to post-quantum cryptography, but the real prerequisite is cryptographic agility, the ability to swap algorithms with minimal disruption as standards, performance trade-offs, and regulatory requirements change, according to Keyfactor. The security case is now inseparable from identity governance, because cryptographic change touches certificates, workloads, and machine trust relationships.
Editorial analysis by NHI Mgmt Group, based on content published by Keyfactor: “Preparing for Quantum Threats: The Importance of Cryptographic Agility”.
Key questions
Q: What breaks when endpoint cryptography is not included in PQC migration?
A: Migration breaks when teams cannot see where vulnerable algorithms and long-lived trust material exist on PCs, so they cannot prioritise remediation or align it to device lifecycle events.
Q: Why does post-quantum migration matter for identity governance?
A: Because identity governance does not stop at user access.
Q: How do security teams know whether cryptographic agility is actually working?
A: Look for central policy control, asset visibility, and the ability to swap algorithms or providers without application redesign.
Practitioner guidance
- Audit embedded cryptographic dependencies Identify where algorithms are hard-coded in applications, libraries, firmware, and identity trust chains so you know what will need replacement during PQC migration.
- Map certificate and workload blast radius Trace which certificates, services, and automated workloads would break if a signing or key algorithm changed, then prioritise the highest-coupling paths first.
- Design for algorithm substitution Require cryptographic policy layers, configuration flags, or abstraction points that let you switch algorithms without redesigning products or identity workflows.
Bottom line: Post-quantum migration is constrained less by algorithm availability than by how easily organisations can change cryptography without breaking trust paths.

Cryptographic agility is the missing governance layer in PQC migration. The article shows that the hard problem is not only selecting post-quantum algorithms, but making cryptography replaceable without destabilising identity and trust services. Certificates, workload authentication, and protocol dependencies all become change surfaces when algorithms move. Practitioners should treat agility as a lifecycle control, not a one-time crypto decision.
A question worth separating out:
Q: How do organisations handle different cryptographic requirements across regions?
A: By making cryptographic policy selectable and portable, rather than embedding one global algorithm choice everywhere. That allows the same product or platform to support region-specific requirements without creating separate code paths, trust models, or identity architectures.
