Remote Gateway (https://rdg.southfieldgrange.org.uk/rdweb)
This will give you the ability to run applications and a desktop remotely so this is the direct replacement for SGD. (login and run “Remote Desktop”) This is internet explorer (Windows) only.
If you want to run on mac, see this guide
For other platforms, ios etc, see the ICT Team.
If the above link does not work, then please try the following file, run this from your machine and it should allow you direct access to the Remote Gateway.
