Post-Quantum Transition

Post-quantum transition is a governance programme.

The post-quantum transition is not only about selecting new algorithms. It is about knowing where cryptography is used, which systems and business services depend on it, who owns the change, what must happen first and how progress will be evidenced.

CipherWyze helps organisations turn post-quantum transition from a technical scramble into a governed programme of work.

Late starts compress the execution window and increase delivery risk.

The transition window

The issue is readiness, not only algorithms.

No regulator has yet told your organisation to run a post-quantum programme. Every one of them has already told you to manage ICT risk and to evidence how. That obligation exists today, it does not expire, and post-quantum transition is the largest cryptographic change most organisations will have to evidence against it.

The immediate problem is usually not algorithm replacement. The immediate problem is readiness:

  • What cryptography is in use?
  • Which assets are exposed?
  • Which systems support long-lived data?
  • Which suppliers and vendors are involved?
  • Which business services are dependent on affected cryptography?
  • Which teams own remediation?
  • What evidence will satisfy boards, auditors, regulators and customers?

Without those answers, late migration becomes compressed, expensive and operationally risky.

On the standards themselves: the three core post-quantum standards were issued in August 2024. The stateless hash-based signature standard has not yet been published, and NIST's transition guidance remains an initial public draft. National guidance published to date sets recommended migration targets rather than statutory deadlines. Accurate as at August 2026.

Inventory first

No organisation can govern what it cannot see.

A practical PQC programme starts with cryptographic inventory and CBOM-informed visibility across:

Algorithms
Certificates
Protocols
Keys
Libraries
Applications
Infrastructure
Key stores and HSMs
Long-lived data
Business service dependencies

Inventory is necessary, but not sufficient. Organisations also need ownership, prioritisation, remediation planning and evidence. That is where cryptographic governance becomes essential.

Enterprise coordination

Post-quantum transition affects more than security teams.

Post-quantum transition can touch every layer of the enterprise technology estate. This is why the transition must be governed as an enterprise programme, not managed as isolated technical projects.

PKI and certificates
TLS and network protocols
APIs and services
Identity and access systems
Software delivery pipelines
Cloud infrastructure
Embedded systems
Suppliers and partners
Payment and financial messaging ecosystems
Long-lived archives and sensitive data
Board and regulator questions

The questions will be about governance and evidence.

CipherWyze helps create the operating record needed to answer these questions with defensible evidence.

  • Have you assessed your exposure?
  • Do you know where cryptography is used?
  • Have you identified critical systems and long-lived data?
  • Have you engaged suppliers?
  • Is there a roadmap?
  • Who owns remediation?
  • How are decisions being documented?
  • What evidence shows progress?
  • How are risks reported to executives?
How Navigator supports PQC transition

From awareness to governed transition.

  • Establish cryptographic visibility
  • Identify scope and ownership
  • Prioritise transition activity
  • Track system and business-service dependencies
  • Align work to standards and policy changes
  • Manage remediation actions
  • Capture evidence
  • Report progress to executives, auditors and regulators

Navigator does not replace expert cryptographic judgement. It provides the governance system of record that makes expert judgement actionable, accountable and reportable.

Move from awareness to action

Start before urgency becomes disruption.
