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."

The Executive Mindset: Where Did I Go Wrong? Owning Cyber Risk Before a Breach
Why did my cybersecurity program fail? Post-mortems usually blame the tools, the team, or the vendor. The real cause often sits in the boardroom: a deferred upgrade, an unverified compliance report, a green dashboard nobody questioned. Dewayne Hart walks executives back through the decisions that created exposure long before the attack, drawing on his book Cybersecurity Leadership: How to Develop a Successful Mentality and Win. He then introduces the Big 4 Model, which aligns governance, technology, operations, and people under one security mindset so every business decision accounts for cyber risk.
Attendees will:
- Assign clear ownership under the Leadership Triangle and grant decision authority before a crisis.
- Use the Big 4 Model to test whether their security is real or assumed.
- Answer ""where did I go wrong"" before a breach forces the question.

Lateral Thinking: Stop the AI-Powered Hacker's Next Move Before They Make One
Your team closed 4,000 tickets last quarter. The attacker read none of them. Adversaries now use AI to scan exposures, chain vulnerabilities, and move laterally faster than any human team can track. Yet most security teams still count scans and closed tickets while the paths to critical systems stay open. Dewayne Hart shows how Continuous Threat Exposure Management (CTEM), backed by AI, cuts an endless patch queue down to the few attack paths that put revenue, data, and operations at risk.
Attendees will:
- Find the gateway, not the headline: trace the paths an AI-assisted attacker would take to critical assets.
- Apply the CTEM cycle and AI to rank fixes by business impact using a P1–P4 model, not raw severity scores.
- Report progress to executives as attack paths closed, not tickets processed.
Best for: CISOs, SOC and Vulnerability Management Leaders, IT Operations, Risk & GRC Teams, Industry Conferences
