Citrix, inadvertant security issue?

If your users use Citrix Secure Access Gateway, am I correct in thinking all they need to do is essentially use a web browser, visit a specific URL and then they will view the company’s servers and desktop session in a browser window? Is there any specific minimum requirements needed on machines that are to use the CAG?

Also, as it is a real benefit to have such a remote access solution in place, do you still have remote working policies? Am I correct in thinking if someone accesses CAG from an un-trusted machine it could have a key logger on it that could be slurping up your user’s domain credentials? How do you deal with this? Do you have approved machines they can use to access CAG or no policy? What about user’s home/personal machines? They could to have a key logger on them? Its one thing having a handy remote access solution but the last thing you want is for this to be a loophole for someone to harvest a companies domain credentials (keys to the doors as we call them).
