What Code 4 Security Services does

Code 4 Security Services is a US private physical-security provider that hires and trains personnel drawn from military, security, and law enforcement backgrounds to deliver contracted guarding services. The firm's service portfolio spans six core lines: Security Guard Services, Armed Security, Mobile Patrol Services, Event Security, Corporate Security, and Integrated Security. Target end-markets are organized into nine verticals — Commercial Properties, Industrial and Manufacturing, Financial Services, Healthcare, Government, Residential, Energy, Construction, and Events — indicating a deliberate broadening from any single-sector anchor.

The firm was founded in 2017 and operates across 101-250 employees, with an operating footprint anchored in Fort Collins, Colorado, and a registered address at 129 W Sherman Way, Nixa, Missouri. Go-to-market is direct B2B contract sales of manned security hours, with pricing not publicly disclosed. No technology products, APIs, integrations, app surfaces, patents, certifications, or funding rounds are disclosed in the available data; the offer is fundamentally labor-based.

Operationally, Code 4 has been folded into Citadel Security Group, a veteran-owned security platform established in 2007. Citadel is the named strategic operating parent, contact details have been migrated to Citadel's central channels ([email protected], 877-639-4301), and the public positioning emphasizes continuity of local service, leadership preservation, and access to Citadel's broader operational depth, training infrastructure, and investment capacity. The combined entity claims 18 years in business, 400+ clients, $3B in assets protected, and a 95%+ client retention rate at the Citadel group level, though none of these metrics is segmented to Code 4 specifically. No revenue, customer concentration data, or growth metrics are disclosed.
