DigiCert Private Root CA

Anchor your private certificate infrastructure with a dedicated root CA designed for enterprise trust domains. DigiCert Private Root CA gives security and infrastructure teams a controlled foundation for issuing and governing internal certificates across applications, devices, and services that should not depend on public trust chains. Use it to define your own certificate policy, maintain separation between internal and external trust, and support lifecycle decisions that align with your security architecture. For organizations running segmented networks, regulated environments, or large-scale internal services, a private root reduces dependency on third-party issuance models and keeps trust decisions inside your control. This is the right choice when certificate governance matters as much as certificate delivery. It supports the architectural discipline required for private PKI: clear trust boundaries, predictable issuance, and a root of trust built for enterprise administration rather than consumer convenience. For teams standardizing identity across infrastructure, applications, and connected systems, it provides the control plane behind every internal certificate chain.
