DigiCert’s Post-Quantum Cryptography (PQC) Maturity Model guides organizations in preparing for the quantum threat, which could break current encryption. It defines four stages—Novice, Apprentice, Practitioner, and Master—based on knowledge and readiness. Progression involves understanding encryption use, adopting certificate management platforms, ensuring crypto-agility, testing hybrid RSA/PQC certificates, and securing high-value assets. The goal is full visibility, automated management, and readiness to deploy PQC without disrupting systems. Early action mitigates “harvest now, decrypt later” risks and ensures resilience as quantum technology evolves.
