Former Chief Information Security Officer
Michael T. Dent is the retired Chief Information Security Officer (CISO) for Fairfax County Government, Virginia — one of the largest and most technologically advanced local governments in the United States. Over more than two decades of service, Dent built and led Fairfax County’s enterprise cybersecurity, risk, and privacy programs, safeguarding critical infrastructure, sensitive data, and digital citizen services for more than 1.2 million residents.
Appointed in 2002 as the county’s first CISO, Dent architected a comprehensive, enterprise-wide cybersecurity framework that evolved alongside rapid digital transformation and a constantly changing threat landscape. His leadership unified 60+ county agencies under consistent information security standards, policies, and risk management protocols — transforming cybersecurity from a technical function into a core pillar of county operations.
Under Dent’s direction, Fairfax County achieved and maintained:
• Zero successful ransomware or breach incidents resulting in service disruption during his tenure.
• 99.9% endpoint protection coverage across county devices and networks.
• Deployment of multi-factor authentication (MFA) countywide — years ahead of many state and federal agencies.
• Development of a 24×7 Security Operations Center (SOC) and centralized incident response capability.
• A mature data privacy and governance program aligned with national frameworks such as NIST and ISO 27001.
Dent also established Fairfax County’s annual Security Awareness Day, one of the first large-scale local government employee cybersecurity education programs in the region. Since its inception, more than 10,000 employees have participated annually in training, live simulations, and awareness sessions — dramatically improving phishing resilience and overall security posture.
Regionally, Dent served 16 consecutive terms as Chair of the Metropolitan Washington Council of Governments (MWCOG) Chief Information Security Officers Committee, guiding cybersecurity collaboration across local governments in the National Capital Region. Through his leadership, jurisdictions improved cross-boundary incident coordination, resource sharing, and emergency preparedness for cyber and critical infrastructure threats.
Before joining Fairfax County, Dent managed information security at the Virginia Department of Corrections, where he implemented statewide cybersecurity standards and compliance programs across all correctional facilities.
A U.S. Army veteran, Dent served in the 3rd U.S. Infantry Regiment (The Old Guard) — including the Presidential Escort and Honor Guard units — experiences that instilled the discipline, focus, and leadership under pressure that would later define his career in cybersecurity.
Dent’s leadership has been widely recognized in both government and industry circles. In 2025, Government Technology magazine named him among the Top 25 Doers, Dreamers & Drivers, honoring his role as a national thought leader in local government cybersecurity. His insights have been featured in publications including Government Technology, Toggle Magazine, The Cyber Guild, and GovExec.
Known for his collaborative and strategic approach, Dent has long championed the belief that cybersecurity should enable — not hinder — mission success. He is credited with helping Fairfax County become a benchmark for resilience and public-sector cyber maturity, balancing innovation with risk management and operational continuity.
Now retired from Fairfax County, Michael Dent continues to advise governments, industry partners, and regional coalitions on cybersecurity strategy, ransomware defense, and digital resilience — with a focus on protecting citizen services and critical infrastructure from emerging threats.
