DigiCert Private Root CA

Build a private trust hierarchy that keeps certificate authority control inside your organization. DigiCert Private Root CA provides the root foundation for internal PKI programs that need strict policy control, predictable certificate issuance, and separation from public trust infrastructure. It is designed for teams that must govern identity for internal applications, devices, and services with clear ownership and auditable trust boundaries. Use it to define the root of trust for enterprise certificate operations, support internal issuance workflows, and maintain consistent policy enforcement across your environment. A private root CA is especially valuable when public trust is unnecessary or inappropriate, such as for internal endpoints, service-to-service authentication, lab environments, and controlled partner access. This model fits organizations that need more than basic certificate issuance. It supports the governance layer behind secure PKI operations, helping reduce dependency on ad hoc certificate management and giving infrastructure teams a stable trust anchor for long-term operations. For enterprises with compliance requirements, segmented networks, or large internal device populations, a private root CA creates the structure needed to manage identity with discipline and clarity.
