With more than 20 years of experience building and leading security operations at the Pentagon, the White House, the Department of Energy, and Fortune 500 enterprises, Orlando will help guide Push Security’s strategy as it redefines how organizations bring active security to the browser.

“Everywhere I’ve worked, from government to the private sector, I’ve seen the same challenge: defenders trying to protect users where they actually work,” said Orlando. “Today, that’s the browser. It’s where attackers are targeting, and where security teams need to be. Push Security is one of the first companies I’ve seen that gets this right, and that’s why I’m here.”

In his new role, Orlando will serve as a bridge between practitioners and Push’s research-driven product innovation, ensuring that Push’s platform addresses the realities of today’s enterprise environment.

“Mark embodies the defender’s mindset—he’s built teams from the ground up, taught thousands of students as a SANS instructor, and led security at the highest levels,” said Adam Bateman, CEO of Push Security. “His perspective and credibility will help us scale Push’s impact and ensure defenders can meet attackers where they are—inside the browser.”

Orlando began his career as a SOC analyst and has since built and led security teams at some of the most sensitive and high-profile organizations in the world. Before joining Push, he co-founded Bionic Cyber, where he advised enterprises on building and scaling cyber defense capabilities. He also previously served as CTO of Raytheon Cyber where he defined technical strategy for consulting services, managed services, and strategic accounts worldwide.

Orlando is currently a SANS Certified Instructor and co-author of LDR551: Building and Leading Security Operations Centers, and instructor for SEC450: SOC Analyst Training - Applied Skills for Cyber Defense Operations, and he served in the U.S. Marine Corps as an Artillery Non-Commissioned Officer. His expertise has been featured at RSA, Black Hat, DefCon, and in leading publications including The New York Times, The Washington Post, and Bloomberg. He actively shares his thoughts on the current state of cybersecurity news on his Cybersecurity Leadership Weekly substack: https://markaorlando.substack.com/.
