Patch management is one of the most consistently underestimated security controls — not because businesses don't patch at all, but because "regularly" usually means inconsistently, with no defined timeline and no way to verify it actually happened.

The gap in practice. Most SMBs have automatic updates enabled on workstations and assume that's sufficient. But critical infrastructure — servers, network appliances, firewalls, and third-party applications — often sits outside that automatic update cycle entirely, and nobody owns the responsibility of checking it.

Why attackers exploit this specifically. Once a vulnerability is publicly disclosed, exploitation attempts typically begin within days, sometimes hours. Attackers actively scan for unpatched systems specifically because they know the gap between disclosure and actual patching, in most organizations, is measured in weeks or months — not days.

What "regularly" should actually mean: A defined SLA by severity — for example, critical vulnerabilities patched within 72 hours, high severity within two weeks — applied consistently across every device and system, not just workstations.

Recommended actions:

• Define a written patch SLA by severity level, covering servers and network equipment, not just endpoints
• Maintain an inventory of every device and application that needs patch tracking — you can't patch what you don't know you have
• Verify patches were actually applied, not just scheduled
• Prioritize internet-facing systems and anything handling sensitive data first
