Cybersecurity & AI Security Keynote Speaker; 20-Year Navy Veteran & Retired Chief Petty Officer; CEO of SEMAIS; Author of "Cybersecurity Leadership: How to Develop a Successful Mentality and Win"; Host of the "Chief of Cybersecurity®" Podcast
Dewayne Hart Biography
Dewayne Hart is a cybersecurity strategist, keynote speaker, and author who spent 20 years in the U.S. Navy before bringing that operational discipline to enterprise and government security. He retired as a Chief Petty Officer after maintaining computer and weapons defense systems aboard the USS Kearsarge, USS Constellation, USS Enterprise, and USS Spruance. Those years taught him the lesson at the center of his work today: security holds when leaders prepare before the pressure arrives.
In 2014, Hart founded Secure Managed Instructional Systems, LLC (SEMAIS), a cybersecurity advisory and workforce development firm focused on cyber readiness and governance, risk, and compliance (GRC). His security work spans the Department of Veterans Affairs, the U.S. Army, Duke Energy, PwC, Kaiser Permanente, and Wells Fargo, leading risk mitigation, compliance frameworks, and vulnerability assessments at scale. He holds CISSP, CEH, CGRC, and CNDA certifications and a master's degree in information assurance. His current practice includes vulnerability management and attack surface and exposure management.
As a speaker, Hart helps executives, boards, and security teams move from passive protection to active readiness. He has presented at the National Cyber Summit, InCyber Forum, GovTechCon, the GDS Group Security North America Summit, the Techno Security & Digital Forensics Conference, EC-Council Cyber Talks, and AFCEA Atlanta. His topics range from AI security and ransomware defense to building cybersecurity teams that stay. His methodology, ""putting on a Hacker's Hat,"" trains leaders to anticipate adversarial tactics instead of reacting to them.
Hart is the author of "The Cybersecurity Mindset: A Virtual and Transformational Thinking Mode" (2022) and "Cybersecurity Leadership: How to Develop a Successful Mentality and Win" (2025). He hosts the Chief of Cybersecurity® podcast and YouTube channel, writes the Cyber Talk newsletter on LinkedIn, and is a former Forbes Technology Council contributor.
Based in Atlanta, Hart works with corporations, government agencies, and associations nationwide. His conviction is simple: cybersecurity is a leadership challenge first and a technology challenge second."
Dewayne Hart Speaking Topics
-
AI Under Attack: How Executives Can Govern, Defend, and Win the AI Arms Race
AI is your most productive tool and your adversary’s most productive weapon—and most organizations govern the first while ignoring the second. Dewayne Hart shows leaders where the exposure actually sits: the AI tools already running without approval, the data those tools absorb and leak, and the adversarial techniques that turn a trusted model into an open attack surface.
Walk out able to:
- Recognize where unapproved AI is already operating inside your own environment.
- Ask governance questions that surface risk before you approve a deployment.
- See how adversarial AI and deepfakes undercut the controls you already trust.
Best for: C-Suite, Board, Technology
-
Mission Ready: How to Transform Build, Retain, and Lead Elite Cybersecurity Teams
The cyber talent crisis is not a pipeline problem—it is a leadership problem. Organizations chase identical candidates, then lose them inside two years to burnout and stalled growth. Drawing on 20 years building mission-critical teams in the U.S. Navy, Dewayne Hart introduces the Mission-First Retention Framework: operational purpose, skill alignment, and leadership accountability.
Walk out able to:
- Evaluate non-traditional candidates on capability instead of credentials alone.
- Identify what drives burnout and which conditions leadership actually controls.
- Give your people a reason to stay that compensation alone can never buy them.
Best for: CISOs, HR Leaders, Security Managers, Workforce Development Conferences
