DigiCert Private Root CA

Build a private trust foundation that fits your security model. DigiCert Private Root CA provides the root authority needed to issue and manage certificates within a private PKI, giving organizations direct control over trust policy and certificate hierarchy. This matters when internal systems, devices, and applications need certificates that are not tied to public trust chains. A private root lets teams define how trust is established, how subordinate authorities are organized, and how internal certificate issuance aligns with enterprise requirements. For infrastructure and security leaders, the value is control. Private root infrastructure supports segmentation, internal identity, and policy-driven trust decisions across environments where public CAs are not appropriate. It is especially relevant for regulated networks, internal services, and device ecosystems that require a dedicated trust anchor. Choose DigiCert Private Root CA when your organization needs a durable PKI foundation that supports internal certificate issuance with clear governance and long-term trust management.
