Security leaders need to explain post-quantum cryptography (PQC) in business terms, not just technical ones. This practical guide helps security, risk, and compliance teams frame potential exposure across long-term data confidentiality, digital signatures, authentication, supply chains, intellectual property, contracts, and regulatory requirements.
The guide presents a four-step plan, Discover, Assess, Plan, and Execute, to help organizations inventory cryptographic assets, categorize risk, build a multi-year migration roadmap, and begin phased implementation.
- 01
5-10 Years Plan for a Long-Term Transition
The guide states that cryptographic upgrades have historically taken 5-10 years. The timeline reinforces the need to plan early and account for dependencies, vendor readiness, and the scale of enterprise change.
- 02
Four Steps to Structure the Program
Discover cryptographic assets across applications, certificates, keys, and dependencies; assess assets by algorithm, lifetime risk, criticality, and vendor dependency; plan a multi-year roadmap; and execute through experimentation, validation, and phased rollout.
- 03
Connect Cryptographic Risk to Business Exposure
Use the guide’s board-level framing to discuss potential impacts on encrypted data, digital signatures, authentication, supply-chain partners, intellectual property, contractual obligations, and regulatory requirements without asserting a fixed date for quantum compromise or a guaranteed fine.
