Readiness assessment and migration to the standardised quantum-resistant algorithms.
Every post-quantum migration plan begins with an inventory, and most inventories stall because the team looks for algorithms instead of looking for the places algorithms are decided.
The question that sequences a post-quantum programme is not which algorithm to adopt. It is which of your data, recorded by an adversary today, would still matter when it can be decrypted.
A plan that lists algorithms and a target year is a statement of intent. A plan that survives review names sequenced workstreams, dependency owners, interim states and the decisions that are already overdue.
Combining a classical and a post-quantum key exchange is now the default for TLS. Understanding why the combination is used—and what it adds to every handshake—makes the deployment decision straightforward.
Key exchange migration is largely a configuration change. Signature migration runs into certificate sizes, fixed-width image headers, verifiers you cannot update and archives that must stay verifiable for decades.
