A coverage gap is an area where expected security visibility, control, or response capability is missing or materially incomplete. It matters because security programs often fail at the edges where teams assumed a control or telemetry source existed but it did not.
What is Coverage Gap?
Coverage gaps may appear in asset inventory, logging, detection content, segmentation, identity, email filtering, cloud monitoring, or many other domains. Identifying them is essential for honest posture assessment and prioritized remediation.
What Coverage Gap Commonly Supports
Common uses include posture review, control assurance, attack-surface analysis, telemetry planning, and program gap remediation.
Coverage Gap vs. Verified Coverage
A coverage gap means important systems, risks, or behaviors are not adequately seen or controlled. Verified coverage means the team has evidence the area is addressed effectively.
Frequently Asked Questions
Why do coverage gaps happen?
Because environments change faster than documentation, ownership, and controls often keep up.
Can a small gap matter a lot?
Yes. Attackers often succeed through narrow blind spots rather than broad obvious failures.
