Mark Lueken
Chief Information Officer · Cybersecurity Leader · Entrepreneur
Twenty-plus years leading IT and cybersecurity teams in the Illinois Army National Guard. Founder of three businesses across cybersecurity, land investment, and short-term rentals.
Strategy. Security. Service.
I'm Mark Lueken, Chief Information Officer for the Illinois Army National Guard. I've spent over twenty years building IT and cybersecurity capability for organizations that can't afford to fail — from data centers in Springfield to distributed teams in Afghanistan.
I lead a red team of more than one hundred cybersecurity professionals at the annual Cyber Shield exercise, advise leadership on enterprise security and risk, and have directed the migration of major infrastructure to Azure Government Cloud. Outside the Guard, I run three businesses focused on bringing the same standards of precision and integrity to the private sector.
By the numbers
Customers migrated to Azure Cloud under my leadership
Volunteer hackers led in offensive cyber operations during Cyber Shield
Army Meritorious Service Medals awarded for IT leadership excellence
Three businesses, one standard
Each company applies the same principles: precision, persistence, and protection of what matters most.
