Mark has been in IT for almost 20 years. His current role as a Cyber Security Design expert at SAP involves him having an excellent understanding of SAP policies & procedures, external compliance requirements, and industry best practices and helping SAP products and services meet and exceed those benchmarks. Before joining SAP in 2018, Mark held previous positions with a CPU manufacturer where he helped launch a motherboard, a physical security company, and a Fortune 50 company. He also helped a bank achieve its first PCI compliance, and he has helped secure a research foundation. Mark has been teaching at SANS since 2017, and he holds GMON and GCIH certifications.
After getting his feet wet as ”The X Security Guy” and doing forensics for a bit, he had the opportunity to build a security operations center at a financial services company, a highly regulated environment. After running that for a few years, Mark jumped at the opportunity to build a cyber fusion center from scratch. He has had the privilege and opportunity to work with an organization over time and see what it takes to make something work long term. “You will not hear me advocate for techniques that only work on paper or aren’t reasonable long term,” he says.
Mark is really excited to be in cybersecurity, as he used to play cops ‘n’ robbers with the kids from his neighborhood when he was young. But nowadays, it’s no longer a game. “As a Cyber Defender, there are literal bad guys attacking us… international adversaries reaching into our data centers, attacking our employees, and stealing money and intellectual property from us. In Cyber Defense, we get to search for those bad guys and kick them out! I think SOC employees basically should wear capes; we are superheroes.”
Not only does Mark teach students how to control an organization’s network and protect it against cyber-attacks, in his spare time he also teaches car control and driving skills to new drivers. Alongside that, he has been volunteering through a program where he is teaching high school students. “That is where I learned how to engage with and educate students. I wanted to layer on these newfound teaching skills with my expertise and excitement in the Cyber Defense space.” Mark is also a faculty member of the SANS Technology Institute, an NSA Center of Academic Excellence in Cyber Defense and multiple winner of the National Cyber League competition.
Mark is well-known for his high energy in class. “I use my energy to partner with my students, leading them on a journey from the morning of day 1 through the afternoon of day 6. I aim to provide an open and relaxed classroom where students are engaged via high energy aural, visual and kinaesthetic methods.” Nothing makes him prouder than seeing people enter their first Cyber Defense jobs and helping them turn into professionals. “I have a former direct report who is now running a SOC at an MSSP,” he says proudly. But also getting the certifications that enable a business to launch a new product line is a highlight of his career. “And, last but not least, working with the bank to pass their first PCI audit” is an experience that remains top of mind for Mark.
In addition to his job at SAP and his work teaching for SANS, Mark has his own consultancy firm that is focused on providing quality IT services to a small number of businesses in the SMB market. “We provide additional expertise or manpower to enable them to securely use IT to better their business.” Also, Mark loves his six cats and driving on racetracks. But not at the same time though, because “that would be weird,” he laughs.
Mark is very experienced, straight to the point, and always willing to answer any questions.
The use of Taylor Swift song lyrics was fantastic. Additionally, Mr. Jeanmougin provided excellent real-world anecdotes.
Mark is clearly experienced and knowledgeable but also humble and helpful. I would recommend him as an instructor for any SANS course that he is able to teach.

In Digital Forensics, Incident Response, and other Cyber Security topics, we're frequently tasked with consuming HUGE amounts of data and finding the "interesting" parts quickly. We've had great tools to do this for decades. But, those tools we're optimized for old computing hardware. In our modern day we have setups with multiple CPU cores and flash storage. This talk will present some techniques to speed up those old techniques fully utilizing modern hardware.

Are you feeling the pressure to do more with less—juggling tool sprawl, alert fatigue, and increasingly sophisticated attacks? Security automation and AI-driven decision support can help streamline operations, enhance accuracy, and accelerate response times.
