Best patch management tools (2026)
The best patch management software to keep operating systems and applications updated and close security gaps automatically.
Patch management is the practice of keeping operating systems and applications up to date — and it's one of the most effective security measures there is, because unpatched software is a leading way attackers get in. Good patch management automates this across your whole fleet. Most leading RMM platforms include it, which is where our picks come from.

How we chose
These picks come from our standard five-part framework — setup, features, security, support and value — weighing hands-on testing where possible, vendor documentation and aggregated, recent user feedback. See how we test. Rankings reflect overall fit for the category; the best choice for you depends on your specific needs, which each entry's "best for" line calls out.
Patch management is usually a feature of an RMM rather than a standalone purchase, so our picks reflect the RMM platforms that do patching best. If you only manage a few machines, built-in OS update tools plus good habits may be enough.
