DigiCert Private Root CA

Build a private trust anchor for workloads that need tighter control than public PKI can provide. DigiCert Private Root CA gives your team a dedicated root authority for issuing and governing internal certificates across applications, devices, services, and infrastructure components. This model is designed for organizations that need clear separation between public and private trust, along with policy control that supports internal compliance requirements. Use it to establish a root of trust for subordinate CAs, segment certificate issuance by environment or business unit, and maintain ownership of the trust chain from the top down. For enterprise teams, the value is control. A private root CA helps reduce dependence on external trust stores, supports internal identity architectures, and creates a cleaner path for certificate governance at scale. It is a strong fit when certificate trust must stay inside the organization’s security boundary and when lifecycle decisions need to align with internal policy rather than public CA constraints.
