DigiCert Additional CA

Add certificate authority capacity where internal trust needs outgrow a single CA. DigiCert Additional CA is designed for organizations running private PKI that need to issue certificates across more teams, more applications, or more segmented environments while keeping policy and governance under control. This type of licensing is typically used when a base private CA deployment needs additional authority instances to support scale, separation of duties, or distinct certificate policies. That matters in enterprise environments where different business units, security domains, or infrastructure tiers must maintain separate issuance rules without losing administrative consistency. For procurement and architecture teams, the value is straightforward: more control over certificate lifecycle operations, less pressure on a single CA, and a cleaner path to expanding trust services as the environment grows. It is a better fit than generic certificate add-ons when the requirement is specifically about extending private CA capacity inside an established DigiCert PKI strategy. Use it to support internal applications, device identity, and infrastructure certificates where trust must remain private and policy-driven. The result is a more scalable certificate foundation for teams that cannot afford weak governance or fragmented issuance practices.
