Bertrum Carroll

Nevada announced the hire of Bertrum Carroll, a retired Army lieutenant colonel, as its new chief information security officer on March 30, 2026. Carroll most recently spent eight and a half years at the workers' compensation insurer Employers, where he was CISO and a vice president.

He replaces Bob Dehnhardt, who retired in May 2025, several months before a ransomware attack disrupted many of the state's operations. Nevada went without a permanent security chief through that incident; Carroll inherits the recovery.

The Governor’s Technology Office says Carroll has joined its Office of Information Security and Cyber Defense in the State Chief Information Security Officer post. According to the release, Carroll said that in his first days his priority is listening, learning and building on what already works.

The state says Carroll has more than a decade of executive cybersecurity experience, including a vice president and CISO role overseeing compliance, risk management and security strategy. StateScoop reports that Carroll spent 27 years in the Army and held private-sector IT jobs at Rockwell Automation and General Electric. The release says he holds the ISO 42001 Auditor, ISO 27001 Lead Auditor, CIPP/US, CISA, CISM and CISSP credentials and is a Certified Internal Controls Architect. He has a bachelor’s degree in computer science, a graduate certificate in cybersecurity and master’s degrees in administration and electrical engineering, the state says.

Employers said when it appointed him that Carroll, based in its Reno office, would lead its strategic security program and provide operational support for security infrastructure. Employers also said he had 30 years in information security roles and had previously been director of global information security operations at SC Johnson. Employers Holdings, Inc. says it is a holding company whose subsidiaries specialize in insurance and services for small and select businesses in low-to-medium hazard industries.

StateScoop reports that the attack affected services at 60 state agencies, among them Public Safety, Motor Vehicles, and Health and Human Services.
