DigiCert Private Root CA

Build internal trust on a controlled foundation with a private root certificate authority designed for enterprise PKI. DigiCert Private Root CA gives organizations a dedicated trust anchor for issuing and managing certificates used by internal applications, devices, and services. For teams running private PKI, the root CA is the anchor that defines trust boundaries and policy. This service is suited to environments that need to separate internal trust from public certificate infrastructure while maintaining control over certificate hierarchy and governance. It supports the operational model many enterprises require for device authentication, internal TLS, and private application trust. A private root CA is not just about issuing certificates. It is about establishing a durable trust model that can be governed over time, aligned to internal security requirements, and integrated into broader PKI operations. For organizations with strict control needs, that distinction matters. It helps justify a private trust architecture where public CA models are not appropriate.
