DigiCert Private Root CA

Establish the trust anchor your internal PKI depends on. DigiCert Private Root CA provides the root authority for private certificate hierarchies, giving infrastructure and security teams a controlled foundation for issuing certificates across internal applications, devices, and users. This matters when public trust is not the goal and governance is. A private root CA helps you define your own trust boundaries, enforce certificate policy from the top of the hierarchy, and support internal identity systems without relying on external certificate authorities. It is a strong fit for organizations that need clear separation between public and private trust domains. For enterprise environments, the value is control. A private root CA supports structured certificate operations, cleaner lifecycle management, and a more deliberate security model for regulated, segmented, or hybrid infrastructures. DigiCert’s private CA approach is designed for teams that need dependable trust infrastructure and the discipline to manage it at scale.
