DigiCert Private Root CA

Build a controlled certificate trust foundation for internal workloads, devices, and applications. DigiCert Private Root CA gives your team a dedicated root authority for private PKI, helping you define trust boundaries, enforce issuance policy, and keep certificate governance inside the enterprise. This matters when public trust is not the right model. Internal services, operational technology, partner access, and machine identities often need certificates that are trusted only within your environment. A private root CA supports that requirement while giving architects a cleaner way to separate internal trust from external-facing services. For organizations managing large certificate estates, the value is control. You can structure your PKI around your own policy, reduce dependence on external trust chains, and create a foundation that supports long-term certificate operations. DigiCert’s enterprise PKI heritage makes this a fit for teams that need more than basic issuance — they need a root authority that can anchor a governed trust model.
