DigiCert Private Root CA

Establish the trust anchor for your internal PKI with a private root CA designed for strict control and long-term stability. As the top of the certificate hierarchy, it defines the trust foundation that supports intermediate CAs and the issuance workflows beneath them. This architecture is essential when you need to keep the root offline, tightly restricted, or reserved for rare administrative actions. By limiting root exposure, teams can reduce risk while preserving a clear chain of trust for internal applications, devices, and services. DigiCert’s private root CA fits organizations that treat certificate governance as infrastructure, not an afterthought. It supports PKI designs where policy, auditability, and separation of duties are central to operational security. For enterprise buyers, the value is architectural durability. A private root CA is not about volume issuance; it is about establishing a controlled trust anchor that can support a disciplined certificate program over time.
