Windows

Windows is moving toward a more secure authentication model by phasing out New Technology LAN Manager (NTLM) in favor of stronger, Kerberos‑based alternatives. This transition is taking a three-phased approach, leading toward disabling NTLM by default in upcoming Windows releases. With each phase come new capabilities so that your organization has the tools, visibility, and compatibility support needed. When will this happen: NTLM has been deprecated since June 2024. Today, enhanced auditing is available as part of Phase 1 toward NTLM disablement. In the second half of 2026, new tools will be available to Windows Server 2025 and Windows 11, version 24H2 and later: IAKerb, Local KDC, upgrade to negotiate Kerberos. With the next version of Windows Server and its corresponding client version, NTLM will be disabled by default. Additional support for handling NTLM-only cases will be built in.
