Short answer: Microsoft deprecated WSUS in September 2024. It still runs today, but it is frozen, Windows-only, and a server you have to keep alive. If you are planning past the next patch cycle, the move is a cloud patch platform that covers Windows, macOS, and Linux, third-party apps, vulnerability detection, and compliance, without a server to maintain.
Is WSUS actually dead?
No, and that is the part that trips people up. Deprecated does not mean removed. Microsoft's September 2024 announcement was explicit: WSUS keeps working and stays supported for its existing functionality, but it is no longer getting new features or investment.
In practice that means WSUS is a tool you can keep using while you plan your exit, not one to build the next five years on. The risk is not that it stops on a fixed date. The risk is that it slowly falls further behind what patching actually requires now: third-party apps, multiple operating systems, vulnerability context, and compliance reporting.
What WSUS never did (and still will not)
Even at its best, WSUS only solved one slice of the problem:
- Microsoft updates only. WSUS patches Windows and Microsoft products. The third-party applications that cause most of your real-world vulnerabilities (browsers, runtimes, PDF readers, conferencing tools) were always on you.
- Windows only. No macOS, no Linux. If your fleet is mixed, WSUS was never the whole answer.
- A server to run. WSUS is infrastructure: a Windows Server, storage for the update content, a database, and the care and feeding that comes with all of it.
- No vulnerability context. WSUS tells you an update is available. It does not tell you which missing patches are actually being exploited in the wild.
- No compliance scoring. Nothing for CIS, DISA STIG, or NIST.
Deprecation just makes a long-standing gap permanent.
What to look for in a WSUS replacement
Whatever you move to, hold it to a higher bar than "deploys Windows updates":
- Third-party app patching alongside the operating system, so one tool covers the whole attack surface.
- Windows, macOS, and Linux from one place, so a mixed fleet is one workflow instead of three.
- No server to maintain. A cloud-managed agent means there is nothing to patch, back up, or rebuild.
- Automated rollouts with phased rings and approvals, so you are not babysitting every deployment.
- Vulnerability detection so you can prioritize the patches that matter, not just the ones that exist.
- Compliance scoring (CIS, DISA STIG, NIST) built in, not sold as a separate product.
How TridentStack Control replaces WSUS
TridentStack Control was built for exactly this transition. One agent handles:
- Patching for Windows, macOS, and Linux from a single cloud console, with deployment rings, approvals, and pre-staging.
- Third-party application updates alongside the operating system, so you retire WSUS and the pile of side tools at the same time.
- Vulnerability detection with CVE and known-exploited context, so you patch what is actually dangerous first.
- Compliance scoring for CIS Benchmarks (Level 1 and 2), DISA STIG, and NIST.
There is no WSUS server to maintain, because there is no server at all. And the first 200 endpoints are free forever, then 5 dollars per endpoint per month with every feature included. For a lot of teams the entire migration off WSUS lands at zero cost.

WSUS deprecation FAQ
Is WSUS deprecated?
Yes. Microsoft announced that Windows Server Update Services (WSUS) is deprecated in September 2024. It still works and remains supported for existing functionality, but Microsoft is no longer investing in new features.
Does WSUS still work after being deprecated?
Yes. Deprecated does not mean removed. WSUS still syncs and deploys Microsoft updates today. But it is frozen: no new features, no third-party app patching, no macOS or Linux support, and you still maintain the server yourself.
What is the best WSUS replacement?
The best replacement covers what WSUS never did: third-party application patching, macOS and Linux alongside Windows, vulnerability detection, and compliance scoring, all without a server to maintain. TridentStack Control does this from one cloud console, with the first 200 endpoints free.
Is there a free WSUS alternative?
Yes. TridentStack Control is free for your first 200 endpoints forever, then 5 dollars per endpoint per month, with every feature included. For most small and mid-size fleets the entire deployment is free.
Can I patch third-party apps without WSUS?
WSUS only patches Microsoft products. A modern patch management platform patches third-party applications too, alongside the operating system, so you are not running WSUS plus a separate tool for everything else.
