DigiCert Private Root CA

Anchor your private certificate infrastructure with a root CA designed for controlled trust and long-term governance. DigiCert Private Root CA gives security and infrastructure teams a dedicated trust anchor for internal certificate hierarchies, helping separate enterprise-issued identities from public web PKI. Use it to define policy at the top of your private PKI, then issue through subordinate authorities that match your operational model. That structure supports tighter control over certificate lifecycle decisions, clearer separation of duties, and a cleaner path for internal applications, devices, and services that require authenticated trust without exposure to public CA dependencies. For organizations running large-scale internal environments, a private root is more than a technical component. It is the foundation for consistent trust, auditability, and certificate governance across data centers, cloud-connected workloads, and managed endpoints. DigiCert’s private CA model is built for teams that need a durable trust anchor and the operational discipline to support it.
