Episode Details
Welcome to the #CyberChats Summer 2025 Series!
In this episode of #CyberChats, we sit down with Greg Sisson, COO of CI-Discern and former CISO for the U.S. Department of Energy, for an engaging conversation on navigating a cybersecurity career across government and industry.
Greg shares lessons from nearly 40 years in public service before transitioning into the private sector with EY and eventually launching his own firm. Greg breaks down what it really means to lead in cybersecurity—whether you’re in uniform, in government, or in the boardroom. We dive into the differences between working in public vs. private cybersecurity, the lessons learned from both, and how young professionals can find their footing in a field that never stops evolving.
