When a major breach hits, the recovery effort is often shaped by a CISO who knows how to steady the organization, rebuild trust, and create long term resilience. Many security leaders have stepped into difficult moments and turned them into opportunities for deeper change. The CISOs below are often referenced in industry reports and case studies for their work in restoring security programs after serious incidents.
Chris Krebs, former CISA Director
Krebs is not a corporate CISO but has advised on several major breach responses. His work often focuses on regulatory alignment, incident recovery, and large scale operational reform.
George Kurtz, CrowdStrike
As CISO and CEO, Kurtz rebuilt CrowdStrike’s security posture after a significant incident. He pushed for proactive threat hunting and the use of AI to improve defenses.
Jen Easterly, CISA Director
Easterly has supported post-breach transformations at both national and enterprise levels. Her focus includes resilience, coordinated response, and long term governance improvements.
These leaders show how a thoughtful and disciplined approach can help organizations recover from major breaches. Their work continues to guide the industry on what effective post-breach transformation looks like.
