We use it at work when we have customers using our computers or devices remotely, so that they don't get infected by malicious software like viruses etc (malware).
The fact you can control what happens if there's an issue with their client side computer/device makes things easier for them as well us! There are some features I would love more of but nothing major really comes up from time being used - its great in helping keep my co workers safe online whilst working away without getting attacked themselves :D.
