Some remote applications like Remote desktop application (Anydesk and TeamViewer), Download managers, etc. get automatically block if HTTPS inspection is enabled. You don't require any policy or configuration for blocking purpose.
Prerequisites
Remote applications like Anydesk and Teamviewer should block automatically if HTTPS inspection is enabled. No need to configure any policy for blocking purpose.
Note: It has been observed that Remote applications like Anydesk and Teamviewer get access to internet if not blocked by firewall. To control these types of Remote applications via SafeSquid proxy (Secure web gateway) you should first block it on the firewall.
Configuration on Remote applications
Set proxy settings on Anydesk application.
If authentication is enabled you have to specify Username and Password on Anydesk application.
Anydesk should not take auto proxy settings: If you set proxy in IE browser or chrome browser and you select "Try to detect the proxy server" option on anydesk, it should not take proxy automatically. You must have to configure proxy on anydesk application.
After doing above configuration you should restrict
Restrict Ammy admin
Restrict Team viewer
Restrict Webex
Restrict Splashtop
Restrict Anydesk
Note: To block single application from above list please refer link Restrict Anydesk
How to create policy without Application Signature
If application is not categorized under default Application Signatures, find User-agent using SafeSquid's extended logs or any other traffic capturing tool.
Add that User-agent or hostname of websites under Custom Setting > Request Types section.
Bind that created user group and Request Type in Access Profile section and specify the action as per the requirement.
