DigiCert Private Root CA

Anchor your internal trust model with a private root CA built for enterprise certificate governance. DigiCert Private Root CA gives security and infrastructure teams a controlled foundation for issuing and managing certificates across internal applications, devices, and services. It is designed for organizations that need to define their own trust hierarchy, enforce certificate policy, and keep sensitive identity operations inside a private PKI boundary. This model is well suited for environments where public trust is not enough: internal web services, device authentication, service-to-service encryption, and regulated workloads that require tighter control over certificate issuance. By centralizing root authority, teams can standardize trust decisions, reduce operational drift, and maintain clearer separation between public-facing and internal identity infrastructure. For enterprises with complex estates, a private root CA also supports long-term governance. It helps establish a durable trust anchor for subordinate issuing CAs and downstream certificate workflows, making it easier to align security policy with operational requirements. The result is a cleaner PKI architecture with stronger control over who can issue what, where trust is established, and how certificate policy is enforced.
