DigiCert Private Root CA

Build a private trust foundation that matches the way your organization operates. DigiCert Private Root CA provides the root of trust for internal certificate hierarchies, giving security and infrastructure teams tighter control over how certificates are issued and trusted inside the enterprise. This matters when public trust is not the right model. Internal applications, device fleets, operational systems, and segmented environments often require a private certificate authority that can support policy-driven issuance without exposing trust decisions to external dependencies. A private root CA helps establish that control at the top of the hierarchy. For teams running mature PKI programs, the value is in governance and consistency. A private root CA supports a cleaner trust architecture, making it easier to define certificate policies, manage subordinate authorities, and maintain a stable internal trust anchor over time. That stability is important when certificate trust underpins authentication, encryption, and device identity across critical workloads. Choose this when your environment needs a dedicated root of trust for internal PKI rather than a generic certificate service. It is the foundation for organizations that treat identity infrastructure as core infrastructure.
