5 Ways to Close the 'Exploitability Gap'
SC Media, Friday, May 1st, 2026
Organizations must act on early exploitability indicators rather than waiting for formal confirmation like KEV or EPSS scores.
Vulnerability management teams face a shrinking exploitation window where attackers can exploit vulnerabilities within days or hours of disclosure. The 'exploitability gap' is the period between when meaningful signals indicate exploitability and when formal confirmation arrives-a gap that has become the critical challenge in vulnerability prioritization.
Rather than relying solely on downstream indicators like CISA's KEV catalog or EPSS scores, organizations need a layered, exploitation-informed decision model that combines early indicators such as public proof-of-concept code, remote exploitability, and weaponization evidence with internal business context. Security teams must shift from reactive prioritization to acting when vulnerabilities are 'decision-ready' rather than 'confirmation-ready' to reduce exposure before exploitation materializes.
