We use WebVideoActiveX Control plugin on IE for our CCTV systems web portals.
Since installing Sophos Endpoint, trying to do anything on the web portals is causing massive browser lockup and can take a long time to load.
Is there anything i can do to get this back to working normally?
You can exclude the URL for the web portals in the policy and that should resolve and performance issue - being aware that you need to trust those URLs explicitly.
Web Control policy will cover this. Unless…
Web Control policy will cover this. Unless there are downloads - which would be covered by Web Protection.

It really depends on how the plugin works. Is this Windows 10? Have you tried adding a website exclusion (global settings) for 127.0.0.1? Sometimes these plugins communicate with the browser over loopback. Is this a cloud service or a local address the browser is connecting to? In the same exclusion place, you can add the IP of the intranet address. That will take web protection/control out of the equation for that site.
I highly discourage a loopback exclusion - this is a large security degradation and should only be done in rare specific circumstances.
It's pretty low risk. It would only prevent a file being served from a local "web server" process over HTTP being scanned before hitting the browser. Assuming the file being served wasn't coming from an excluded location the web server process wouldn't have been able to read the file to serve it as real-time scanning would have blocked it. Hard to say if it would help in this scenario without knowing how the software works and what the issue is,
This is for Windows 10. We have about 50 CCTV systems in the company, they are local addresses to each site.
I'll try adding one to the exclusions list, was hoping to not have to do this as there are so many, but if it's the only way then so be it.
