Operator, Author, and Recognized Thought Leader

Cyber Security Expert

What makes someone a credible cyber security expert in 2026 is narrower than it used to be. The field has drifted with commentary from people who left operational roles a decade ago. The work on this page is different: active executive advisory at Netsync, a Top 5 global Thinkers360 ranking, three published books, 150+ tabletop exercises, and 100+ keynotes on the industry's flagship stages.

Keynote Topics

Expert Witness and Media Commentary

Expert witness engagements in cybersecurity litigation, regulatory matters, and insurance disputes. Media commentary for broadcast, print, and industry outlets on breaches, emerging threats, and policy developments. Availability is limited and subject to conflict review.

Best for: Litigation teams, regulatory counsel, journalists

Duration: Engagement-based

Executive Advisory and Keynote Speaking

Dual-track engagement model: standing advisory for a small roster of enterprise clients, and keynote speaking for events that want a practitioner rather than a commentator. The two reinforce each other, and every keynote is better for the advisory work happening that same week.

Best for: Enterprise C-Suite, conferences, flagship industry events

Duration: Variable

Published Research and Thought Leadership

Three published books, an active newsletter, and contributions to industry publications on AI governance, ransomware economics, and board-level cyber risk. Available for co-authored research projects and foreword contributions.

Best for: Publishers, research programs, industry analysts

Duration: Project-based

I don't give speeches. I share what I've learned running security programs, building AI systems, and advising boards — so your audience leaves with something real.

What Audiences Say

Feedback From Event Hosts and C-Suites

“

Mark stands apart. His credibility isn’t rooted in a title from years ago — it’s built through the work he’s doing every day in the field. When he speaks about our technology, enterprise buyers pay attention because they know his perspective is grounded in real-world experience.

Shira Rubinoff

CEO, The Cybersphere Group

“

Mark delivers more than a presentation — he delivers operational insight from the front lines. Instead of theory, he shares what is actually working in real environments. Our audience of CISOs and security leaders left with practical strategies they could begin implementing immediately.

Frequently Asked Questions

What qualifies someone as a cyber security expert?
A useful working standard is the combination of current operational exposure, independent peer recognition, a published body of work, and demonstrated communication ability with non-technical audiences. Credentials without current work age quickly in this field.
Do you take expert witness engagements?
Selectively. Cases involving ransomware response, breach response adequacy, cyber insurance disputes, and board-level governance are the most common. Each engagement is screened for conflicts against existing advisory clients.
Are you available for media interviews?
Yes, with lead time where possible. Frequent topics include major incident commentary, AI governance, ransomware economics, SEC cyber disclosure rules, and emerging board-level cyber risk issues. Broadcast, print, and podcast formats all work.
How do you stay current as an expert?
Daily client work at Netsync is the single biggest input. Every week involves real C-Suite conversations about active threats, new deployments, and live incidents. That beats any amount of secondary research for staying calibrated to the current environment.
