Every second Tuesday of the month, Microsoft releases its security updates, and every second Tuesday, IT teams everywhere brace for the same routine: review what’s changed, test for breakages, and roll updates out before the window for exploitation gets too wide. For a lot of businesses without a structured process, “patch management” really means “wait for something to break, then patch reactively.”

The risk with this approach isn’t theoretical. Once a vulnerability is publicly disclosed, whether through the patch release itself or independent research, the time between disclosure and active exploitation in the wild has been shrinking for years. Attackers reverse-engineer patches to figure out exactly what was fixed, then build exploits targeting anyone who hasn’t applied the update yet. A delay of weeks, once considered reasonably safe, now leaves a meaningful window of exposure.

A proactive patch management process doesn’t mean blindly deploying every update the moment it’s released, untested patches occasionally cause their own problems. It means having a defined cadence: a testing window on a small pilot group, a defined rollout schedule for the wider estate, and clear ownership of who’s responsible for tracking what’s been applied where. Centralised patch management tooling (whether that’s Intune, WSUS, or a third-party RMM platform) makes this dramatically more manageable than manually tracking patch status across dozens or hundreds of endpoints.

The other half of the equation is visibility. It’s not enough to assume patches are being applied; you need reporting that confirms which devices are up to date and which have fallen behind, so gaps get caught before they become an incident rather than after.

None of this needs to be complicated, but it does need to be deliberate. If your current patching process is closer to “we’ll deal with it when something breaks” than a defined, monitored schedule, that’s a gap worth closing.
