1. Discovery

In the Discovery phase, organisations identify all cryptographic assets across applications, servers, cloud platforms, and network devices. This includes locating certificates, keys, algorithms, communication protocols, and any system relying on classical encryption. The goal is to build a complete inventory of crypto dependencies so PQC planning becomes accurate and actionable.

2. Analysis

During the Analysis phase, each discovered asset is assessed against emerging quantum threats. Organisations gain visibility into which algorithms are quantum-vulnerable, which systems rely on long-lived data confidentiality, and where PQC migration will have the greatest impact. This stage forms the baseline risk posture for your quantum-readiness roadmap.

3. Remediate

The Remediation phase focuses on developing and implementing practical mitigation strategies. This includes upgrading algorithms, shortening certificate lifetimes, improving key management, adopting PQC-safe standards, and planning migration to NIST-approved quantum-resistant cryptography. The aim is to reduce exposure while maintaining system stability.

4. Monitor

In the Monitoring phase, organisations continuously track progress of their PQC migration. Certificate renewals, algorithm replacements, compliance status, crypto-inventory changes, and new vulnerabilities are automatically observed. This ensures quantum readiness does not deteriorate over time — especially as systems evolve.

5. Continuous Improvement

Quantum readiness is never a one-time project. As standards mature and threats evolve, organisations refine their cryptographic strategy and optimise their PQC rollout. Continuous Improvement ensures long-term resilience by keeping cryptographic assets updated, aligned to new PQC standards, and ready for future quantum-resilient protocols.
