Verification closes the loop

Patching a vulnerability and confirming it with a scanner does not prove an attacker can no longer succeed. Only 30% of CISOs test after patching to verify risk was actually reduced. A case study of a global investment firm shows how retesting after remediation dropped attacker-achievable impacts from 251 to zero. Mature security programs shift from measuring ticket closure to proving attack paths are gone through continuous verification — validate, fix, verify, repeat.
