DigiCert Private Root CA

Build internal trust on a root authority you control. DigiCert Private Root CA is designed for organizations that need a private PKI foundation for issuing and managing certificates across internal systems, applications, and services. For infrastructure, security, and compliance teams, a private root CA is about control, consistency, and policy enforcement. It supports certificate lifecycles that stay aligned with internal requirements instead of relying on public trust chains for every use case. That matters when you need to secure internal applications, device identities, service authentication, or segmented environments with stricter governance. This offering fits enterprise procurement models and is well suited to teams standardizing certificate issuance across multiple workloads. Compared with simpler certificate tools, a private root CA gives you the authority layer needed to define trust on your terms and maintain it across the environment.
