We are looking at incorporating a new company into our domain. They use a different content filtering tool (for the moment ;-). What is the best way to implement Proxy Chaining (we use on premise appliances) with a cloud hosted solution.
MWG has next hop proxy events which can be setup in the rules to forward traffic. The rule might look like something below.
If you're using a cloud proxy, I would wonder how they are authenticating as that might be an issue if they require more complex methods. If they're simply identifying you based on your public IP, then you shouldnt have any issues forwarding traffic.
