Healthcare Enterprise Replaces Cisco Vulnerability Management (Kenna) with Nucleus

A large healthcare enterprise was running a critical vulnerability management program on Cisco Vulnerability Management (Kenna) when innovation stalled and end-of-life risk became impossible to ignore. With thousands of findings piling up and manual workarounds slowing progress, the team needed a replacement that preserved continuity while fixing what Kenna could no longer support.

After migrating to Nucleus, the organization completed its initial cutover in under 30 days without disrupting day-to-day operations. More importantly, automated reprioritization immediately changed how the enterprise understood risk. It narrowed a backlog of more than 4,000 items to just nine urgent, publicly exploitable exposures, giving its teams a clear and defensible “do-now” list.

Beyond prioritization, the enterprise replaced spreadsheet-driven tracking with automation across routing, ownership, exceptions, and reporting. The result was a program that scaled across multiple affiliated entities while maintaining clear governance, accountability, and visibility.
