DigiCert Private Root CA

Build a private trust hierarchy for internal systems with DigiCert Private Root CA. This service is designed for organizations that need a root of trust they can govern directly, with certificate issuance aligned to internal policy rather than public CA requirements. It is well suited to enterprise PKI programs where trust must be segmented by environment, business unit, or security domain. By maintaining a private root, teams can issue certificates for internal applications, infrastructure services, and managed devices while preserving strict control over trust distribution and lifecycle management. For security and infrastructure leaders, the value is precision. A private root CA supports cleaner separation between public and internal identity, helps reduce exposure tied to external trust dependencies, and gives teams a durable foundation for certificate-based authentication. It is especially relevant in regulated environments, isolated networks, and large-scale deployments where certificate governance must be consistent and auditable. DigiCert Private Root CA is built for organizations that treat PKI as core infrastructure, not a commodity service. It provides the trust anchor needed to support internal authentication, policy enforcement, and long-term certificate strategy.
