From Uncertainty to Action: DigiCert Quantum Central and the Race to PQC Readiness

This IDC Market Note examines DigiCert Quantum Central, a new solution within the DigiCert ONE portfolio previewed on July 1, 2026, to help organizations begin post-quantum cryptography readiness. DigiCert, which serves more than 125,000 organizations, including 90% of the Fortune 500, built Quantum Central to give security and IT teams a practical, self-service way to discover cryptographic assets, identify quantum-vulnerable systems, prioritize remediation, and track migration progress across fragmented, multi-vendor cryptographic environments toward a clearly defined readiness road map.The note traces how Quantum Central's inventory, policy, remediation, and reporting workflow, informed directly by DigiCert's own internal migration experience, could reshape the broader PQC readiness marketplace and customer expectations around evidence-backed compliance posture. It also reviews the competitive challenges DigiCert faces in converting free preview users into paying customers as general availability approaches. It offers IDC's point of view on the solution's differentiation against established GRC, CTEM, and certificate lifecycle management vendors already active in the category."Quantum Central turns a vague mandate into a sequenced workflow," says Philip D. Harris, research director, Governance, Risk, and Compliance Solutions, IDC. "Visibility, not certainty, is the starting point."
