DirectAccess is a 
VPN like remote access technology that is
a core component of the Windows Server 2012 R2 Remote Access role. 
DirectAccess is a unique solution that is designed to replace traditional VPN access.
It provides secure, seamless, transparent and always-on remote access to corporate networks for clients running Windows 7 Enterprise, Windows 7 Ultimate, Windows 8.1 Enterprise, and Windows 10. DirectAccess provides these advantages over most traditional
VPN solutions:
- Active Directory Domain joined client computers connect automatically rather than connections being user initiated
 - Connections seamlessly work through all firewalls
 - Supports selected server access when connected
 - Can use IPSEC authentication to corporate servers
 - Supports end to end encryption of the connection
 - Provides transparent failover to another corporate network access point or site if required
 - Supports offline domain join for clients that have never been on the corporate network
 - Allows central IT staff to manage the remote computers over the DirectAccess connection.
