Custom SSL Certificate and SSL Key were imported to SWG (Symantec Web Gateway) in Administration > Configuration > Proxy under SSL Deep Inspection Settings. When click on "Export" button next to Export SSL Certificate, it still exports the default certificate. Is this an expected behavior or is it supposed to export custom certificate?
SWG is working as designed. The "Export" button is designed to export the default certificate.
Custom SSL certificate needs to be installed on all protected PC for SSL Deep Inspection to work properly.
