DigiCert Private Root CA

Build a private trust hierarchy around a dedicated root CA designed for enterprise certificate governance. DigiCert Private Root CA gives infrastructure and security teams a controlled anchor for issuing and managing internal certificates across users, devices, applications, and services. It supports the operational model required for private PKI, where trust boundaries, issuance policy, and lifecycle control must stay inside the organization. This service is well suited for environments that need a clear separation between public trust and internal identity infrastructure. Use it to establish certificate policies, maintain administrative control over issuance, and support authentication requirements for internal systems that cannot depend on public certificate authorities. For teams managing regulated workloads, segmented networks, or large-scale device fleets, a private root CA helps keep trust decisions consistent and auditable. DigiCert’s enterprise PKI approach is built for organizations that need dependable certificate governance at scale. Rather than treating certificates as isolated assets, this root CA serves as the foundation for a structured trust model that can support long-term security operations, internal compliance requirements, and repeatable certificate issuance across the environment.
