Security Guards in Denver

What sets SecureOne apart from other Colorado security companies

A downtown Denver office tower, a distribution center off the interstate and a new apartment community in the suburbs do not need the same guard on the same schedule. That is the starting point for every Colorado account we take on. Before we quote, we visit the property, ask what has gone wrong there before, and write post orders around how the site actually runs day to day.

In Colorado, the officers on your property are SecureOne officers, hired, trained and supervised by us rather than handed off to a partner company. We staff long-term contracts as well as short-term needs such as a construction phase, a store opening or a weekend event. You can read more about our Denver team on SecureOne's Colorado security services page, or see the full breakdown of each service on our Colorado security services page.

Built for Colorado Conditions

Security planned around Front Range weather, crowds and growth

Colorado sites come with conditions of their own. Snow and ice change how officers patrol parking areas and check entrances through the winter months. Stadiums, arenas and downtown districts draw heavy crowds on game days and event nights, which affects nearby garages, hotels and storefronts. Growth across the suburbs keeps adding apartment communities, retail centers and job sites that need coverage from day one.

We factor all of that into the plan, then keep supervisors checking on posts so the coverage holds up season after season.

Our Services

Colorado security guard services, from one post to many sites

Pick a single service or combine several. In many cases a patrol or a camera trailer can cover hours that would otherwise need a full-time officer, and we will say so when it fits.

Unarmed Security Officers

The backbone of most Denver accounts: lobby and front desk coverage, access control, visitor check-in and courteous help for tenants, guests and staff.

Officer coverage ›

Armed Security Officers

For sites that handle cash or high-value goods, or where past incidents point to a higher level of risk.

When armed makes sense ›

Mobile Patrol

Scheduled or random checks, lock-ups, unlocks and alarm response for properties that do not need an officer on site all night.

How patrols work ›

Remote Camera Monitoring

Solar-powered mobile camera trailers with 24/7 remote monitoring, a good fit for open lots and active job sites.

Camera trailers ›

Event Security

Armed and unarmed officers for game nights, concerts, openings and one-day events, planned with you in advance.

Event coverage ›

Off-Duty Police

Licensed off-duty and recently retired police officers when a property or event calls for a sworn presence.

Industries

Who we protect in Denver and across Colorado

Commercial real estate and offices

Property managers count on our officers for lobby desks, tenant escorts, after-hours lock-up and vacant suite checks. SecureOne's commercial real estate security program is built for multi-tenant buildings and business parks.

Logistics and warehouses

Logistics security officers handle the gate and the dock, check in drivers and trailers, keep vehicle logs and walk the yard between shipments.

Hospitality and assisted living

Hotels and assisted living communities need officers who are calm and welcoming with guests and residents while still keeping an eye on entrances, parking and late-night activity.

Apartment and residential communities

Community security officers and patrols give residents a steady, professional presence, with compliance checks and clear incident reports for the management office.

Construction sites

Camera trailers and roving officers keep materials and equipment under watch after crews leave, for a single phase or the life of the project.

Retail centers

Our retail officers are a visible, friendly presence that discourages theft and vandalism. When there is a problem, they de-escalate and call the police. They do not chase people.

How We Work

What a Colorado client can expect from us

Post orders written for your site

Every client gets post orders for their own property, and officers are trained on them before they work the post alone. Our officers are First Aid and CPR certified.

Clear reporting in Vision InSites

Officers file reports, photos and patrol checks in Vision InSites, our real-time security reporting platform, so you can see what happened on each shift.

Tracked patrol vehicles

GPS Insight provides real-time vehicle tracking and in-car 360-degree cameras for patrol vehicles, and WinTeam keeps scheduling and billing accurate.

One contact, around the clock

You get a single point of contact available 24/7, backed by SecureOne's 24-hour dispatch center and supervisor inspections at no additional cost.

SecureOne is not the lowest-priced security company, and we say so up front. Clients stay because officers show up on time, supervisors stay in touch and problems get fixed quickly, which is why about 76 percent of our new clients come from referrals.
