Q-READY JOURNAL · QUANTUM SECURITY

Practical notes for quantum-ready decisions.

Clear, evidence-led guidance for security, engineering and leadership teams preparing for post-quantum migration.

THE JOURNAL

Start with the foundations, then move into the operating choices that make a quantum-safe transition manageable.

02Migration planning

Crypto-agility is the bridge to quantum-safe migration.

The safest migration plan is not a one-time algorithm swap. It is a system that can test, change and govern cryptography without disrupting the business around it.

TAKEAWAYMake cryptography replaceable before it becomes urgent to replace.
03Supplier readiness

Ask suppliers for quantum-safe evidence, not promises.

Your quantum migration plan is only as useful as the answers you can get from the providers around it. A practical supplier questionnaire turns vague roadmaps into dated, testable evidence.

TAKEAWAYA supplier roadmap becomes useful when it names the boundary, the test and the owner.
04Risk prioritisation

Turn a cryptographic inventory into a decision queue.

A list of algorithms is not yet a migration plan. The useful next step is to connect each cryptographic dependency to data lifetime, business impact, evidence and an owner who can move it forward.

TAKEAWAYAn inventory creates value when every uncertain item has a next decision, an owner and a date.
05Pilot design

A quantum-safe pilot must prove rollback.

A migration pilot is useful when it shows how a real boundary behaves under change, failure and recovery—not when it produces another broad claim that the estate is quantum safe.

TAKEAWAYA safe pilot proves the change, the limits and the way back before it proves scale.
