The JHSecure VPN provides a secure connection to the Johns Hopkins campus network when off-campus. The VPN can be used to connect from home or a remote location to access applications, websites, files, etc. that are only available when on the Johns Hopkins campus. The VPN is not needed to access your Exchange Email, Virtual Desktop, SharePoint, or Lync.
