DigiCert Private Root CA

Build a controlled trust foundation for internal applications, devices, and services with DigiCert Private Root CA. Designed for organizations that need a private certificate authority rather than public web trust, it gives security teams a dedicated root for establishing certificate hierarchies, enforcing issuance policy, and maintaining separation between internal and external trust domains. This model fits environments where certificate governance matters as much as certificate issuance. Use it to anchor subordinate CAs, support internal TLS deployments, and maintain a clear trust boundary for enterprise systems, operational technology, and private services. By keeping root authority under direct organizational control, teams can align certificate policy with security standards, audit requirements, and lifecycle processes. For infrastructure teams, the value is precision and control. A private root CA reduces dependence on public trust models, supports internal identity architectures, and provides a stable base for long-term certificate operations. It is a strong fit for enterprises that need to issue and manage certificates at scale while preserving policy consistency across business units and environments.
