Re: The most simple way is not mentioned here?
Everything you need on the fileservers? - sure if you're just editing documents, how about the myriad of servers, networks and applications that many of us need to access daily that are blocked (quite rightly) over VPN access?
If I use my company laptop from home I'm severely limited, RDP to that laptop sat on the company network from my home machine over VPN, which is definitely as secure as my work machine, and all functionality is available to me.
