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.

Best for: Teams wanting strong, automated OS + third-party patching
NinjaOne's patch management is a standout: reliable, automated patching for operating systems and a wide range of third-party apps, with clear reporting. Part of a polished, well-automated RMM.
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.
