DigiCert Additional CA

Add certificate authority capacity where governance matters most. DigiCert Additional CA is designed for organizations that need to extend private PKI operations without collapsing multiple trust domains into a single issuing path. It supports cleaner separation of duties, more precise policy enforcement, and better alignment between certificate issuance and application ownership. For infrastructure teams running multiple business units, environments, or compliance boundaries, an additional CA can reduce operational friction. It gives you room to segment issuance by use case, control certificate profiles more tightly, and preserve administrative clarity as demand grows. That matters when internal TLS, device identity, and application authentication all depend on predictable certificate lifecycle management. This is the kind of licensing that supports mature PKI design: deliberate, auditable, and easier to scale than ad hoc expansion. Use it when a single CA no longer fits the structure of your environment, but you still need consistent policy, trusted issuance, and enterprise-grade control.
