Since this technology is no longer developed further by Microsoft, I have will blogging on the Technical implementation of “Always On VPN”. For more information on the “Always On VPN overview and requirement”, see the following link. Always On VPN aims to address several shortcomings of DirectAccess, including support for Windows 10 Professional and non-domain joined devices, as well as cloud integration with Intune and Azure Active Directory. Windows 10 Always On VPN is the replacement for Microsoft’s DirectAccess remote access technology.

This presents a challenge for deployment scenarios that require the VPN connection to be established before the user logs on. – DirectAccess is provisioned to the devices – Always On VPN is provisioned to the user.

These two technologies provide seamless, transparent, always-on remote network access for Windows clients.

Brief difference between Windows 10 Always On VPN and DirectAccess.
