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

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.

Best for: C-Suite, Board, Executive Leadership, Enterprise Summits, Government Leadership

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

Human in the Loop: Building Mission-Ready Cyber Teams in the Age of AI

AI now handles the entry-level work that once trained new cyber defenders, and many organizations have stopped hiring juniors. That cuts costs this year and empties the bench five years out. The talent crisis was never a pipeline problem. It is a leadership problem, and AI has raised the stakes. Drawing on 20 years building Navy teams, Dewayne Hart presents the Mission-First Retention Framework: operational purpose, skill alignment, and leadership accountability, rebuilt for teams where people and AI work side by side.

Attendees will:

  • Identify which roles AI will reshape, which it will replace, and which skills to build for both despite AI being the new commodity.
  • Hire for capability and AI fluency, not credentials alone, and teach defenders to think like attackers.
  • Discover what keeps cyber talent on the team when pay alone cannot.

Best for: CISOs, HR Leaders, Security Managers, Workforce Development Conferences, Veteran Transition Events

The Hacker's Hat Looks Good on You: One Size Fits Every Employee in the Room

Attackers do not need to break a firewall when an employee will open the door. Most awareness programs end with an annual quiz, so the same organizations fail the same phishing tests year after year. Dewayne Hart hands every person a hacker's hat and shows them their inbox, phone, and daily routine through an attacker's eyes. The hat does not make anyone a hacker; it teaches them to ask the adversary's questions, a concept from his book "The Cybersecurity Mindset: A Virtual and Transformational Thinking Mode". Employees leave as the first line of defense, not the weakest link.

Attendees will:

  • Spot AI-generated phishing, deepfakes, and pretext calls by thinking like the attacker behind them.
  • Trust their cyber senses when a call or request feels wrong, and report the warning fast.
  • Own their role in defense instead of leaving security to IT.

Best for: All-Employee Conferences, Cybersecurity Awareness Month, HR & Culture Events, Healthcare, Government, Education

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

Dewayne Hart Reviews

  • "I had the pleasure of hearing Dewayne Hart speak at GovTechCon Mission 2025, and his session was genuinely one of the highlights of the event. Dewayne has a commanding yet approachable presence that instantly draws you in. His insights on cybersecurity leadership, growth, and innovation in the government technology space were both practical and inspiring. What stood out most was his ability to connect with the audience on a personal level you could tell he speaks from real experience and genuine passion for developing others. I left his session feeling motivated and with a clearer perspective on my own professional journey. I would highly recommend Dewayne as a speaker for any event focused on cybersecurity, leadership, or professional development."
