DigiCert Private Root CA

Build a private trust foundation that stays under your control. DigiCert Private Root CA provides the root authority for internal PKI deployments, giving security teams a dedicated trust anchor for issuing and governing certificates across enterprise systems. That is essential when public trust is not appropriate for internal applications, devices, or segmented environments. A private root CA supports tighter policy control, clearer trust boundaries, and more deliberate certificate hierarchy design. It helps organizations separate internal trust from external-facing services, which can simplify governance and reduce exposure. For teams managing regulated workloads, internal services, or device identity programs, a private root CA creates the authority needed to issue certificates according to enterprise rules rather than public CA constraints. This product fits organizations that need durable control over internal trust infrastructure. It is especially relevant when certificate policy, issuance authority, and lifecycle governance must remain inside the enterprise security model. DigiCert’s private root CA approach gives PKI architects a foundation for building internal trust with the control and consistency enterprise environments demand.
