# Patch Management

Patch management is the cycle of finding which software needs an update, testing the fix, deploying it, and confirming it took. The hard part is rarely installing a patch. It is keeping an accurate inventory of what runs where, validating that an update will not break a dependent system, and pushing it across a fleet quickly without disrupting production. Many teams stage rollouts, patching low-risk systems first and watching for regressions before touching critical ones.

It matters because most breaches abuse a flaw that already had a fix. Log4Shell (CVE-2021-44228) stayed exploitable in many environments for months after the patch shipped, because organizations could not find every affected service. The window between disclosure and a working exploit keeps shrinking, so slow patching is its own exposure.

Patch management is the remediation arm of [vulnerability management](/glossary/vulnerability-management). It closes the issues that [vulnerability scanning](/glossary/vulnerability-scanning) finds, tracks the relevant [CVE](/glossary/cve) entries, and feeds [exposure management](/glossary/exposure-management) by reducing the count of fixable weaknesses on the surface.

In a Trickest workflow you scan exposed services for outdated versions, match them to published advisories, and re-run after a patch window to confirm the fix landed, so unpatched hosts surface instead of slipping through a manual checklist.
