Jamf Pro requires a valid SSL certificate to ensure that computers and mobile devices communicate with the Jamf Pro server and not an imposter server.
For Jamf Cloud-hosted Jamf Pro instances, the SSL certificate is managed by Jamf.
If you have an on-premise environment, you must create or upload an SSL certificate for your on-premise instance of Jamf Pro. The Apache Tomcat settings in Jamf Pro allow you to create an SSL certificate from the certificate authority (CA) that is built into Jamf Pro. You can also upload the certificate keystore for an SSL certificate that was obtained from an internal CA or a trusted third-party vendor. For more information on creating an SSL certificate, see the Enabling SSL on Tomcat with a Public Certificate article.
If your environment is clustered, you must log in to the Jamf Pro web app for each Apache Tomcat node and create or upload any SSL certificates for each node.
