DigiCert Private Root CA

Establish the trust foundation for private PKI with DigiCert Private Root CA. This service is designed to serve as the root authority for internal certificate hierarchies, giving enterprise security teams a controlled starting point for issuing and governing private certificates. A private root CA is essential when internal systems must remain outside public trust chains while still requiring strong identity and encrypted communication. With a dedicated root, organizations can define certificate policy from the top of the hierarchy, align subordinate issuance to internal requirements, and maintain a clear separation between public and private trust domains. DigiCert Private Root CA is a strong fit for environments that demand strict governance, including regulated industries, segmented networks, and hybrid estates with large numbers of internal workloads. It supports the operational discipline needed to manage certificate trust over time, helping teams preserve consistency across applications, devices, and services that depend on private identity. For infrastructure leaders, the value is control: a root authority that supports long-term PKI structure, policy consistency, and enterprise-grade trust management for internal systems.
