Skip certificate check for SSL connections

[fablser]

Hello

I have KSC + KES 11 in my network. 

I am using a proxy server for content filter an antivirus purpose. I would like to use KES 11 too, in order to scan ssl connections for web traffic. If my proxy warns or block a page, the user does not see nor Proxy Warn Page, nor Kaspersky page. He simply see a generic browser error (see screnshot).

I suppose that this happens because my proxy uses a self-signed certificate. Is there any way to set KES/KSC policies to skip certificate check?

Thanks
