title: Visual Studio Team Services - secure access to office environment only
body: <p>We use Visual Studio Team Services to manage our sourcecode and scrum.
  We have 2 developers working at 2 separate offices.</p>
  
  <p>I do not want developers logging in at home and grabbing code for their own use.</p>
  
  <p>How can i lock down the access to Visual Studio Team Services from only the offices PCs?</p>
