DigiCert Private Root CA

Create a controlled trust foundation for internal systems, devices, and applications with DigiCert Private Root CA. Designed for organizations that need to issue certificates under their own policy domain, it supports private PKI architectures where root trust must remain under direct administrative control. This model is suited to environments that separate public-facing trust from internal identity, including enterprise networks, industrial systems, partner integrations, and regulated workloads. By keeping the root CA private, teams can define issuance rules, certificate profiles, and trust distribution according to internal security requirements rather than external CA constraints. DigiCert Private Root CA is a strong fit when certificate governance matters as much as certificate issuance. It helps reduce dependency on public trust stores for internal assets, supports consistent identity management across large fleets, and gives infrastructure teams a cleaner path for lifecycle control. For organizations standardizing on private PKI, it provides the authority needed to protect internal communications, authenticate systems, and sustain trust at scale.
