DigiCert Private Root CA

Build a private certificate authority foundation for systems that need controlled trust, not public web PKI. DigiCert Private Root CA gives enterprise security teams a dedicated root for issuing and governing certificates across internal applications, devices, and infrastructure services. Use it to define trust boundaries, enforce issuance policy, and support certificate-based authentication in environments where compliance, segmentation, or operational control matters. A private root is often the right choice for internal workloads, OT networks, partner ecosystems, and regulated deployments that require ownership of the trust chain. This service is designed for organizations that need more than basic certificate issuance. It supports a deliberate PKI architecture where root trust is kept under your control, helping reduce dependency on external trust stores and giving administrators a cleaner path for policy enforcement and lifecycle management. For teams standardizing enterprise identity and certificate operations, DigiCert Private Root CA provides the trust anchor that makes the rest of the PKI model work. It is the foundation for scalable internal trust with the governance expected in high-stakes infrastructure environments.
