Certificate Management for PCI DSS, ISO 27001, and SOC 2

Certificate management is a significant compliance concern because auditors for PCI DSS, ISO 27001, and SOC 2 commonly expect organizations to maintain a complete certificate inventory, verify that certificates are valid and trusted, document issuance and renewal procedures, and preserve records showing those procedures were followed over time. PCI DSS v4.0.1 explicitly requires valid, trusted, inventoried certificates for cardholder data in transit, while ISO 27001 and SOC 2 address certificates through broader cryptography, asset management, and access-control policies that organizations define and auditors test. Auditors typically sample both from inventory to network endpoints and from endpoints back to the inventory, making incomplete spreadsheets or recent cleanup efforts insufficient, particularly for SOC 2 Type II observation periods. Maintaining accurate evidence is difficult because certificates may originate across cloud services, Kubernetes clusters, internal CAs, appliances, and third-party systems, while shorter public TLS lifetimes increase renewal workloads. The material argues that combining issuance records, continuous network discovery, policy enforcement, access controls, expiry monitoring, and durable audit logs can provide shared evidence across frameworks, and presents Infisical Certificate Management as a tool intended to centralize these activities and support audit preparation.
