Delivering mission-critical security solutions built on precision, integrity, and real-world experience.
SENTRYSIX was founded in 2016 by U.S. Air Force veteran and law enforcement officer Zach Rice with a vision rooted in service beyond the uniform. After years of protecting his country and community, he recognized a common challenge—many veterans leave service with unmatched skills, leadership, and dedication, yet struggle to find meaningful careers where their purpose continues.
Zach built SENTRYSIX to change that—creating a company grounded in the same discipline, integrity, and mission-first mindset forged through military and law enforcement service, while delivering next-generation security solutions to clients who demand excellence.
More than a security company, SENTRYSIX exists to create opportunity. It is a place where veterans can continue their mission, grow within a strong culture, and be part of something bigger than themselves. When you partner with SENTRYSIX, you’re not just choosing a trusted security provider—you’re helping provide careers, restore purpose, and support those who have already served our nation. Together, we’re building safer communities while ensuring the legacy of service lives on.
At SENTRYSIX, our mission is to deliver reliable, mission-critical security and defense solutions that perform when it matters most.
