A severity score alone does not determine business priority. Combine asset criticality, exposure, exploitation evidence and existing controls. CISA KEV informs prioritization of exploited vulnerabilities; US federal deadlines do not automatically apply to every organization. This pack extends the scanning guide into finding management.

Map the process
