Ok, we just did a test by adding L3 FW rule to deny tcp/443 to *.teamviewer and it works but in this way it will only block Teamviewer and not some other tools that are working in the same way. Dificult to imagine that a solution like Meraki cannot block specific apps of threats.

This is what we do, the port tcp/443 is open for any destinations and we are only allowing domains on the webfiltering but some tools that are not allowed like teamviewer are bybassing the webfiltering.

Hello, We are having a security breach in our environment, we are using SD-WAN solution based on MX. We have a L3 FW rule that permit TCP/80 and TCP/443 for web surfing and we are limiting websites by configuring whitelist. We are discovered that some non-HTTPS trafic can pass through the MX bypassing the web filtering probably because the web filtering is acting only for HTTP/HTTPS. We are now trying to find a way to block those trafic and only allow HTTP/HTTPS protocols. Is there a way to achieve this ? Thanks
