Hello, I have Fortigate 200D in my organization and some users are using Google Chrome VPN Extension called VPN-free.pro , Proxy is closed at application control and Proxy.HTTP aswell, Is there a custom signature i can use to block that vpn Note my proxy list is up to date.

Each version of the extension is a different (new) signature for firewall, so if you have web filter license you have better use this feature to block this kind of traffic. Also you can set a group policy for chrome at your active directory to block chrome using extensions or only this extension. A had in the past a major problem with vpn proxies and support guided me through web filter. Also you can make a ipv4 rule to block traffic to the ip 93.1170.141.132 (freevpn ip) and set this rule to be executed first.
