Marcin_B,    It doesn't let you add a custom cert for the web interface, as SAE 2 and 4 won't allow you to. It as been requested, but they still haven't added that feature.    Let me know if this helps.    
Hello team, I just deployed SCG fresh install on production environment. I deployed loads of SAE VE instanced befor so I know its limitations, pros and cons. I can see that SCG VE offers LDAP integration which was not available in SAE VE. But in many deployment my customers asked me about possibility to upload Custom Web SSL certificate for SAE VE / SCG appliance. Is it possible in SCG? I can't see option to generate CSR Request and upload custom cert in SCG WebGUI. Thank you in advanced.   Best Regards Marcin.
