Vulnerability management at a large utility operator

Cybersecurity tools can identify known vulnerabilities. The harder problem is getting an organization to act on them continuously. Security operations may find the issue, infrastructure teams may own the server, and business teams may control the maintenance window. When those responsibilities and handoffs are unclear, assets can remain exposed even when everyone has done their individual job.

The program had to work inside an operating utility where uptime matters, teams carry different responsibilities, and remediation competes with other operational work. New threats also continue to appear, so a one-time cleanup would not solve the problem.

I aligned security, IT infrastructure, and business stakeholders around one shared measure: reduce the number of open vulnerabilities across the technology landscape.

I used Qualys dashboards to make the count and movement visible, helped resolve a long-standing blocker that prevented servers from being patched at scale, and clarified who was responsible for identifying, planning, and applying remediation.

I then established a recurring operating cycle: Detect, Analyze, Plan, Remediate, and Celebrate. Celebration was deliberate. Much of this work is repetitive, urgent, and easy to overlook, so recognizing progress helped sustain the operating rhythm.

The program cleared a long-standing patching blocker, reduced the accumulated server-vulnerability count, and left a recurring cross-functional remediation process. The program described here was completed in 2024.

Cybersecurity is often described as a technology problem. In practice, known risk accumulates when ownership, handoffs, and operating routines fail. Tools make risk visible; the organizational system determines whether it is removed.
