Citadel Security is proud to announce a strategic partnership with Code 4 Security Services, a Colorado-based security provider known for its service-first culture, strong local leadership, and disciplined operational standards.
The partnership strengthens Citadel’s presence in Colorado and expands its ability to deliver structured, scalable security programs across commercial, industrial, healthcare, government, residential, construction, and event environments.
Founded on professionalism, accountability, and respect, Code 4 Security has earned the trust of clients throughout the communities it serves. The organization has built a reputation for responsive leadership, consistent site-level execution, and a hands-on approach to client service.
Under the partnership, Chris Villalpando, former CEO of Code 4 Security Services, will transition into the role of Chief Revenue Officer at Citadel Security. In this position, Chris will help guide strategic growth initiatives while ensuring strong alignment between teams and continuity for clients.
“This partnership is built on shared values,” said Justin Hale, CEO of Citadel Security . “Code 4 has established a strong reputation in Colorado through disciplined execution and local leadership. Our goal is to preserve that foundation while strengthening the operational systems, training support, and compliance infrastructure behind it. Together, we are building a stronger platform for long-term, sustainable growth.”
For clients, day-to-day service structures and local leadership remain in place. What changes is the depth of support behind the scenes. By combining Code 4’s local management and client relationships with Citadel’s regional resources and structured operational systems, the partnership creates expanded capabilities without sacrificing responsiveness or accountability.
Chris Villalpando emphasized the alignment between the two organizations. “Citadel and Code 4 share a commitment to professionalism and disciplined operations,” said Villalpando. “This partnership allows us to maintain the service standards our clients expect while gaining additional resources to support training, compliance, and scalable growth. I’m excited to step into this new role and help ensure a smooth transition while positioning the combined organization for continued success.”
Citadel Security, a veteran-owned company founded in 2007, has grown into one of the largest disabled-veteran-owned security firms in the country. The company protects billions of dollars in assets across multiple states and sectors, supported by a leadership team rooted in military and law enforcement experience.
The partnership with Code 4 Security Services reflects Citadel’s continued focus on disciplined expansion, operational excellence, and long-term client relationships.
As both teams move forward together, the shared priority remains clear: deliver structured, accountable security programs led by strong local leadership and supported by scalable operational infrastructure.
