DigiCert Private Root CA

Build private trust from the top down with DigiCert Private Root CA. This service provides the root authority for a private PKI, giving security and infrastructure teams a controlled foundation for issuing and governing internal certificates. It is the layer that defines trust, policy boundaries, and the structure beneath every subordinate issuance path. Use it when internal applications, devices, or services require a private trust chain that stays separate from public certificate ecosystems. A private root CA is essential for organizations that need to manage certificate policy centrally, support segmented environments, and maintain a clear hierarchy for issuance, renewal, and revocation. For enterprise teams, the benefit is architectural control. A private root CA helps standardize trust across large environments, support compliance-driven certificate governance, and reduce the operational risk that comes from unmanaged or inconsistent internal PKI design. It is the right choice when the trust anchor itself must be deliberate, durable, and under direct administrative control.
