St. Louis Security Guard Company
Licensed security officers, 24/7 remote monitoring, and emergency response for businesses across the St. Louis metro.
Expert Security Guarding in St. Louis and Missouri
Prosegur Security's St. Louis branch operates from South 4th Street downtown, a few blocks from the river. The bi-state metro is the defining feature of how we work here: officers scheduled from one office cover sites in Missouri and across the river in Metro East Illinois, which means credentialing, licensing, and post coverage have to account for two regulatory environments rather than one.
The account mix reflects what St. Louis actually builds and researches. Bioscience campuses around Cortex, BJC, and the Danforth Center need lab access control and chain-of-custody discipline. Aerospace and defense sites in Hazelwood and Berkeley run on cleared-facility protocols. Distribution centers in Earth City and along the I-70 and I-255 corridors need dock and yard coverage more than lobby presence. We staff all three, and we pair on-site officers with remote video monitoring from our operations centers when a site needs overnight or perimeter coverage without a full post.
We cover St. Louis City and County, St. Charles, Jefferson, and Franklin counties in Missouri, and Madison, St. Clair, and Monroe counties in Illinois, including Clayton, Chesterfield, Maryland Heights, Earth City, Bridgeton, Hazelwood, Kirkwood, Creve Coeur, Fenton, St. Charles, O'Fallon, Belleville, Edwardsville, Granite City, and Collinsville. Severe weather response, labor actions, and civil unrest are handled by the same local team, escalated through National Contingency Services when a site needs more officers.
Why Businesses in Missouri Trust Prosegur To Be Their Security Service Provider
Local Security Backed by Global Resources
Local insight and the strength of Prosegur's global network power our St. Louis team to deliver reliable, responsive protection across the bi-state metro.
Rapid Response When It Matters Most
With officers on site and 24/7 supervision from our downtown office on South 4th Street, we maintain constant coverage and respond swiftly to incidents across the St. Louis metro, day or night.
Data-Driven Risk Management
We offer more than security guarding. We deliver intelligence-driven programs, using data and analytics to help you identify, assess, and mitigate risks before they escalate.
Scalable Solutions for Any Industry
Bioscience and research campuses, aerospace and defense sites, distribution and logistics facilities, healthcare systems, and corporate offices across the St. Louis metro each present distinct security demands, and our programs are built to address them.
Available Security Services in St. Louis and Missouri
Prosegur delivers customized security services for businesses in St. Louis and across Missouri, offering dependable protection and 24/7 responsive local support for every site.
Licensed Security Guarding
Trained to deliver a visible presence and exceptional service, our licensed security officers protect the region's leading industries. From bioscience campuses around Cortex and the BJC and WashU medical district to aerospace and defense sites in Hazelwood and Berkeley, distribution centers in Earth City and along the I-70 corridor, and office properties in Clayton and downtown, we tailor guarding programs to your needs and risk environment.
Global Risk Services
For companies with national or international reach, our Global Risk Services team provides data-driven intelligence, from travel risk management and threat monitoring to crisis response planning and supply chain risk assessments. For St. Louis bioscience and aerospace clients, that often means protecting product, components, and personnel moving between research sites, plants, and partners.
Security Systems Installation & Integration
Our St. Louis team designs and installs security systems built for your environment, covering video surveillance, access control, and intrusion detection. Whether upgrading current systems or launching something new, we integrate the pieces so they work as one system rather than several, across single sites and multi-location portfolios.
Remote Security Monitoring
Around-the-clock Remote Security Monitoring integrates live video, access control, and intrusion detection with oversight from trained agents in our Security Operations Center. Using AI analytics and real-time feeds, we detect, validate, and address threats before they escalate. For distribution facilities and industrial sites with large yards and long perimeters, it holds coverage on ground that would otherwise need a post at every gate.
Emergency Response
Unexpected events call for swift action. Our National Contingency Services division delivers rapid-response security for emergencies, labor actions, and civil unrest. In this region that also means severe storms and tornado season, along with winter ice events, where sites lose power and access control at the same time. When a location needs more officers than a branch can surge alone, we deploy from our nationwide network.
Enterprise Cybersecurity
We deliver enterprise cybersecurity including threat monitoring, endpoint defense, vulnerability scanning, and incident response. For St. Louis bioscience, defense, and healthcare clients, that includes supporting the compliance requirements those sectors carry.

St Louis Security Services FAQ
Prosegur delivers a wide range of commercial security guard services across the St. Louis metro, serving businesses in St. Louis, Clayton, Chesterfield, Maryland Heights, Earth City, Hazelwood, St. Charles, and O'Fallon. Our offerings include uniformed officers, concierge and front desk services, access control, event security, remote monitoring, and integrated technology customized to your industry and location.
St. Louis companies choose Prosegur for professionalism, reliability, and an integrated approach to physical and remote security. Our officers are scheduled and supervised from our South 4th Street office downtown rather than a regional hub, and they are backed by technology and 24/7 support that lets a program scale without adding headcount at every post.
Yes. Our officers are licensed and registered as required in every jurisdiction where they work, and training covers emergency protocols, de-escalation, customer service, report writing, access control, and site-specific procedures. Missouri regulates private security locally rather than through a single statewide agency, so we manage licensing city by city and county by county to keep multi-site programs compliant.
Remote Security Monitoring combines live camera feeds, two-way audio intervention, and real-time response from trained agents in our Security Operations Center. For St. Louis businesses with large properties or extended perimeters, it enhances protection while reducing the cost of a guard-only staffing model.
Yes. Many St. Louis clients use a hybrid model that pairs on-site officers with remote monitoring. This layered approach increases visibility and responsiveness, and it works particularly well for distribution and logistics facilities in Earth City and along the I-70 corridor, aerospace and manufacturing sites in Hazelwood and Berkeley, corporate offices in Clayton and downtown, and retail centers across the metro.
Our St. Louis team secures bioscience, life sciences, and research campuses, aerospace and defense facilities, healthcare systems and hospital campuses, distribution centers and logistics operations, manufacturing and industrial sites, corporate offices and commercial real estate, universities and educational institutions, government and public sector properties, construction projects, retail and mixed-use developments, and residential communities and HOAs.
Our St. Louis team can usually deploy licensed security personnel within 24 to 72 hours. We handle both urgent and scheduled staffing across the metro, including Clayton, Chesterfield, Maryland Heights, Earth City, Bridgeton, Hazelwood, Kirkwood, Creve Coeur, Fenton, St. Charles, O'Fallon, and Wentzville.
