After nearly three decades in law enforcement and corporate security, I’m proud to share my professional biography—a reflection of a career dedicated to safety, leadership, and service. From high-stakes investigations to executive protection and training the next generation of security professionals, my journey has been driven by a passion for safeguarding people and organizations. Here is my biography.

Mark A. Porter is a seasoned national security and intelligence executive with more than three decades of experience protecting people, infrastructure, and institutions at the highest levels of government and the private sector. From directing global operations with the U.S. Secret Service and shaping counterterrorism policy at the White House to leading Ohio’s homeland security strategy, Porter has consistently delivered visionary leadership, strategic insight, and trusted crisis management. His deep knowledge of public safety, cybersecurity, and threat assessment—paired with his ability to build cross-sector coalitions—positions him as a transformative asset to any board or advisory role.
