days, rendering traditional monthly or quarterly patching cycles dangerously inadequate. Organizations that rely on fixed patching schedules are effectively handing attackers a guaranteed head start. This matters because high-severity vulnerabilities are the primary entry point for ransomware groups and state-linked threat actors targeting critical infrastructure.
