14-Day Patching Rule

Apply qualifying vendor-approved security fixes within 14 days of vendor release. A high or critical vendor rating, CVSS v3 base score of at least 7, or a vulnerability with no vendor severity description can trigger the deadline. For example, a Tuesday update with an unclassified fix is due within 14 days even if a monthly window falls later; assess the whole bundle, release date and supported fix.

Why this term matters for the five controls

Technical-control terms map directly to the five Cyber Essentials controls: firewalls, secure configuration, user access control, malware protection, and security update management. These terms turn the self-assessment from a short answer into something the organisation can evidence.

For a passing submission, the organisation should be able to show the relevant configuration, the owner of the control, how exceptions are handled, and how the control is reviewed over time.

How Fig Group uses this term

Fig Group uses 14-Day Patching Rule as part of a practical Cyber Essentials and compliance vocabulary. The purpose is to make assessment decisions easier to verify: what the term means, where it appears in evidence, which control it supports, and which buyer or assessor question it helps answer.

If this term affects your Cyber Essentials submission, treat it as an evidence question rather than a definition question. Document the relevant owner, system, configuration, policy, or workflow so an assessor can see how the control works in your environment.
