The Jamf PKI Proxy is a command-line application that manages communication between Jamf Pro and Venafi Trust Protection Platform (TPP). Venafi TPP typically runs on a server in a more protected segment of the organization's internal network. The Jamf PKI Proxy acts as a proxy between Jamf Pro and Venafi TPP. This ensures secure communication to Venafi TPP for issuing and revoking certificates without enabling direct access to Venafi TPP from the Internet. The Jamf PKI Proxy utilizes Mutual Transport Layer Security (mTLS) between Jamf Pro and the Jamf PKI Proxy.
