Every Colorado contract starts the same way: a free consultation and a walk of the property. We listen to what you are seeing, then recommend the lightest mix of services that actually covers the risk. In Colorado, your officers and supervisors work for SecureOne, not a partner company.
Unarmed and armed security guards in Denver
Most Denver properties run on unarmed officers. A good unarmed officer knows the tenants and regular visitors, keeps the access points under control and handles a problem calmly before it grows. We place armed officers where the risk supports it, for example at sites that handle cash or high-value inventory, or where earlier incidents involved weapons. We will give you a straight answer on which your site needs.
We hire people with prior military, law enforcement or security experience, then train them on your post orders before they work the site alone. A field supervisor stays with each new officer until they are ready, and every officer is First Aid and CPR certified.
Mobile patrol across the Denver metro

When a full-time post is more than a property needs, a mobile patrol officer can make scheduled or random checks, lock and unlock buildings, check doors, lots and fence lines, and respond to alarms. In winter, patrol routes take snow and ice into account at entrances and parking areas. Patrol vehicles carry GPS Insight tracking and in-car 360-degree cameras, and the patrol report lands in your inbox every day.
Mobile camera trailers and remote monitoring
Our solar-powered camera trailers bring 24/7 remote monitoring to open lots, construction sites and real estate that has no power on site. Each unit offers live monitoring, motion-activated alerts, pan-tilt-zoom cameras and talk-down audio through an onboard speaker, with a backup power system built in.
Event and short-term security
Game days, concerts, grand openings and one-off events all bring crowds, parking pressure and late nights. We staff armed and unarmed officers on short notice and plan the coverage with you ahead of time. In 2019 alone, SecureOne provided more than 80,000 manhours of short-term and event security.
Off-duty police officers
For properties and events that call for a sworn presence, SecureOne's law enforcement team is made up of licensed off-duty and recently retired police officers in good standing. Each one is background checked, trained in SecureOne's force policies and certified in CPR, AED and First Aid.
Colorado industries we protect
Office buildings and commercial property
Lobby desks, visitor management, tenant escorts, after-hours lock-up and vacant suite inspections for downtown towers and suburban business parks.
Logistics, warehouses and industrial sites

Gate and dock control, driver and trailer check-in, vehicle logs and yard patrols for distribution centers and industrial properties.
Construction
New projects across the metro face theft of tools and materials and trespassing after hours. SecureOne's construction site security pairs camera trailers with stationary or roving officers for a single phase or a full build.
Retail
Officers at shopping centers and stores focus on deterrence and customer service. As SecureOne's retail security page explains, they discourage theft, vandalism and car break-ins. If something happens, they de-escalate and call the police. They do not chase people.
Hospitality, assisted living and residential communities
Hotels, assisted living communities, apartment complexes and HOAs use posted officers and patrols for a steady, welcoming presence and clear incident reporting.
How we manage your account
One point of contact is available to you 24/7, and SecureOne's 24-hour dispatch center backs every Colorado post. Reports, photos and patrol checks go into Vision InSites, our real-time security reporting platform. Field supervisor inspections come at no additional cost, and WinTeam keeps scheduling and billing accurate. Our officers wear a tan shirt, black hat, black pants and black shoes. If you have properties outside Colorado, SecureOne can coordinate coverage across the lower 48 states, so you keep one company and one contact.
