Microsoft DirectAccess Formally Deprecated

Today, Microsoft has announced the formal deprecation of DirectAccess. Microsoft DirectAccess is a widely deployed enterprise secure remote access solution that provides seamless, transparent, always-on remote network connectivity for managed (domain-joined) Windows clients. First introduced in Windows Server 2008 R2, it’s been a popular solution with many advantages over ordinary VPN technologies of the past.

Windows Server 2012

DirectAccess was almost entirely rewritten in Windows Server 2012. Many of the features and enhancements offered for DirectAccess with the Unified Access Gateway (UAG – a separate product with additional costs) were built into the operating system directly. In addition, Microsoft introduced integrated load balancing and geographic redundancy features.

Demise of DirectAccess

DirectAccess relies heavily on classic on-premises technologies like Active Directory. All DirectAccess servers and clients must be joined to a domain. In addition, all DirectAccess clients must be running the Enterprise edition of Windows. With organizations rapidly adopting cloud services such as Azure and Entra ID, Microsoft began to develop an alternative solution that better integrated with the cloud. That solution is Always On VPN. With that, Microsoft stopped developing DirectAccess after the release of Windows Server 2012 R2. No new features or capabilities have been added to DirectAccess since that time.

Deprecation

We’ve been speculating about the end of life for DirectAccess for quite some time now. However, this formal deprecation announcement from Microsoft is official. It is the end of the road for this technology. To be clear, though, DirectAccess is available today in Windows Server 2022 and Windows 11. DirectAccess will be included in the upcoming release of Windows Server 2025. However, formal deprecation from Microsoft means they will remove DirectAccess components from the next release of the operating system.

What Happens Now?

Organizations should begin formal planning efforts to migrate away from DirectAccess. Here are a few popular solutions to consider.

Always On VPN

Always On VPN is the direct replacement for DirectAccess. It was designed to provide feature parity for DirectAccess, with seamless, transparent, always-on remote network connectivity. However, Always On VPN better integrates with Entra ID and supports conditional access. It does not require domain-joined devices or servers and works well with cloud-native endpoints. Always On VPN is a good choice for organizations that employ hybrid Entra-joined devices.

Entra Private Access

Entra Private Access, part of the Entra Global Secure Access suite, is an identity-centric zero-trust network access (ZTNA) solution from Microsoft. It is in public preview now and has some compelling advantages over traditional VPNs. However, Entra Private Access is not feature complete today. In addition, it is best suited to cloud-native (Entra-joined only) endpoints.

Absolute Secure Access

Absolute Secure Access (formerly NetMotion Mobility) is a premium enterprise remote access solution with many advanced options. It is by far the best solution on the market today. Absolute Secure Access is a software solution that supports zero-trust configuration and includes many features to improve and enhance security, performance, and visibility. In addition, it provides cross-platform support, including Windows, macOS, iOS, and Android operating systems.

5 Things DirectAccess Administrators Should Know About Always On VPN

5 Things DirectAccess Administrators Should Know About Always On VPNWindows 10 Always On VPN hands-on training classes now forming. Details here.

As I’ve written about previously, Microsoft is no longer investing in DirectAccess going forward. There will be no new features or functionality added to the product in the future. Microsoft is now investing in Always On VPN in Windows 10, with new features being released with each semi-annual update of the operating system. But as Microsoft continues to make the push toward Always On VPN over DirectAccess, many administrators have asked about the ramifications of this shift in focus for enterprise remote access. Here are a few points to consider.

It’s the same thing, only different.

Always On VPN provides the same seamless, transparent, always on experience as DirectAccess. Under the covers, the mechanics of how that’s accomplished changes a bit, but fundamentally the user experience is exactly the same. Once a user logs on to their device, a VPN connection is established automatically and the user will have secure remote access to corporate resources.

The connection is still secure.

Where DirectAccess uses IPsec and Connection Security Rules (CSRs) to establish its secure tunnels, Always On VPN uses traditional client-based VPN protocols such as IKEv2, SSTP, L2TP, and PPTP. Both DirectAccess and Always On VPN use certificates for authentication. However, where DirectAccess uses machine certificates to authenticate the computer, Always On VPN leverages user certificates to authenticate the user.

(Note: Machine certificates will be required for Always On VPN when using the optional device tunnel configuration. I will publish more details about this configuration option in a future article.)

Provisioning and managing clients is different.

The administrative experience for Always On VPN is much different than it is with DirectAccess. Where DirectAccess made use of Active Directory and group policy for managing client and server settings, Always On VPN clients must be provisioned using a Mobile Device Management (MDM) solution such as Microsoft Intune, or any third-party MDM platform. Optionally, Always On VPN clients can be provisioned using Microsoft System Center Configuration Manager (SCCM), or manually using PowerShell.

Security is enhanced.

Always On VPN has the potential to provide much more security and protection than DirectAccess. Always On VPN supports traffic filtering, allowing administrators to restrict remote client communication by IP address, protocol, port, or application. By contrast, DirectAccess allows full access to the internal network after user logon with no native capability to restrict access. In addition, Always On VPN supports integration with Azure Active Directory, which enables conditional access and multifactor authentication scenarios.

It’s built for the future.

Always On VPN also provides support for modern authentication mechanisms like Windows Hello for Business. In addition, Windows Information Protection (WIP) integration is supported to provide essential protection for enterprise data.

Summary

Microsoft set the bar pretty high with DirectAccess. Users love the seamless and transparent access it provides, and administrators reap the benefit of improved systems management for field based devices. Always On VPN provides those same benefits, with additional improvements in security and protection.
