Built on Trust. Driven by Expertise.
Some business partnerships begin with an idea. Others begin with years of trust.
For more than two decades, Derek DeLisio and Mark Elmer built a friendship rooted in a shared passion for helping organizations solve complex security challenges. Throughout their careers, they saw the same pattern repeat itself: companies were investing heavily in security technology but often lacked the independent expertise needed to maximize its value.
Rather than focusing on selling products, they believed customers deserved a trusted advisor—someone who could evaluate their environment, connect disparate systems, optimize performance, and guide them through every stage of the security technology lifecycle.
That shared vision became Octeum.
Founded on a commitment to putting customers first, Octeum was created to help organizations make smarter security technology decisions through unbiased expertise, collaborative partnerships, and innovative solutions. From enterprise access control migrations and custom software integrations to ongoing monitoring and optimization, the company exists to simplify complex security ecosystems and empower customers to achieve their security and safety goals with confidence.
Today, that same philosophy continues to guide every engagement. Octeum remains technology-agnostic, focusing on what is right for each customer—not what is tied to a particular manufacturer or platform. The result is lasting partnerships built on trust, transparency, and measurable outcomes.
What started as a friendship has grown into a company dedicated to helping organizations build stronger, more connected, and more resilient security operations—one partnership at a time.
