Profile bio

About Gary De Mercurio

Charting a course from the skies of the United States Marine Corps to the forefront of cybersecurity, my journey has been anything but conventional. As a UH-1N helicopter pilot in the Marines, I mastered the art of precision, safety, and strategic foresight, skills that later proved invaluable in the civilian sector. At Sikorsky Aircraft, I dived deep into the complexities of aerospace engineering, spearheading international quality and innovation efforts that set new benchmarks for excellence. This chapter in aerospace was not just about enhancing systems and processes but about envisioning and executing solutions that redefined standards.Shifting into cybersecurity felt like a natural progression once I recognized that true security extends beyond the physical realm. My journey, marked by critical roles in high-stakes environments, seamlessly transitioned into leading global cybersecurity initiatives. As a Global Vice President, I steered teams toward a vision where security is all-encompassing, advocating for a strategy that anticipates and neutralizes threats across digital, physical, and human dimensions. This holistic approach to security, inspired by my varied experiences, underscores my commitment to a comprehensive protection paradigm, firmly believing in the integration of cyber defenses as a crucial extension of physical security.Before embarking on this path, I served as a deputy sheriff, an experience that provided a foundational understanding of law, order, and the critical importance of community safety. This role, coupled with my studies in psychology and criminal justice, offered early insights into the complexities of human behavior and risk management. It's a chapter of my life that, while preceding my military and engineering exploits, has remained integral to my approach to security, emphasizing the necessity of vigilance, empathy, and a deep commitment to protecting others.Through every phase of my career, from law enforcement to leading cybersecurity initiatives, the common thread has been a dedication to service, innovation, and the relentless pursuit of excellence. My journey reflects a commitment to not just navigate but to anticipate and shape the future of security, driven by a passion for leadership, a rich tapestry of experiences, and an unwavering focus on making a meaningful impact.

Gary De Mercurio work experience

A career timeline built from the work history available for this profile.

Red Team | Offensive Security | Physical Security

Current

We believe that security is just that, Security, it's not simply data security. All facets need to be secure for your company to truly be doing the right thing. It's like having a three legged stool, sure you can balance on two legs, even one for a while, but eventually you'll fall. We test all three, Logical, Social Engineering and Physical. Not only do we test, but we do our best to hand you the fish at the end of the engagement and the fishing pole. Real security means teaching you how to do things better, sharing the secret sauce in hopes your company is more secure for it. Shouldn't that be what all real security companies strive to do? Try to leave things better than they found them?
