A certificate authority (CA) is a trusted entity that signs and issues the certificates required for certificate-based authentication. It is the central component of the PKI.
In Jamf Pro, you can choose to use a built-in CA, integrate with a trusted third-party CA (DigiCert, Venafi, or Active Directory Certificate Services), or configure your own PKI if you have access to an external CA that supports the Simple Certificate Enrollment Protocol (SCEP). The certificate authorities can be used to issue certificates to both computers and mobile devices.
An external CA can also be used to issue certificates to computers, but this is not enabled by default. For more information, contact your Jamf account representative.
