Patch Gap
Noun · Security & Infosec
Definitions
The period or coverage difference between when a fix is available and when all affected systems have actually been patched. Patch gaps are where many real-world compromises occur because attackers act faster than large organizations can update everything.
In plain English: The risky delay between a patch becoming available and systems actually getting updated.
Example: "The ransomware affiliate exploited the patch gap between vendor release day and the weekend maintenance window."
