GRDX provides security guard services in Loudoun County, including armed and unarmed officers, vehicle patrol and event security. Our headquarters sits in Sterling near Dulles, and every officer is licensed and verified before they are scheduled on a Loudoun post.
Why Loudoun clients call a Sterling company
Our office is in Loudoun, which means supervisors live and drive the same roads our officers patrol. Route 28, the Greenway, Route 7, and Loudoun County Parkway are daily commutes for our team, not lines on a map.
That matters when a post needs coverage at 2 a.m. or a client wants to walk a site on short notice. A field supervisor is reachable around the clock, and if an officer is not the right fit for your property, we replace that officer when you ask.
Property types we protect across the county
Loudoun mixes some of the densest technology infrastructure in the country with horse country, so the work changes from one end of the county to the other.
Data center and tech campuses
Ashburn and the Route 28 corridor hold large campus builds with gatehouses, badge checks, and long fence lines that suit fixed posts plus roving patrol.
Planned communities
Brambleton, Broadlands, One Loudoun, Lansdowne, and Brambleton-style HOAs with pools, clubhouses, and trail networks that need visible evening rounds.
Retail and mixed-use
Dulles Town Center, One Loudoun, and the shopping strips along Route 7 in Sterling and Cascades see holiday crowds and after-hours loitering.
Estates west of Leesburg
Larger private properties toward Purcellville, Middleburg, and Round Hill, where long driveways and outbuildings call for patrol and gate checks.
Security guard services we provide in Loudoun County
Most Loudoun requests fall into a handful of patterns, and the site walk tells us which one applies.
| Site | Service that usually fits |
|---|---|
| Corporate or data center campus | Armed or unarmed officers at access points, plus roving vehicle patrol |
| HOA or gated community | Scheduled vehicle patrol with GPS-verified checkpoints, pool and clubhouse coverage |
| Retail center | Uniformed officers during peak hours, special police where arrest authority helps |
| Private estate | Overnight patrol, gate checks, executive protection for travel or events |
| Construction phase | Night and weekend patrol of laydown yards and equipment |
How patrol is verified on Loudoun routes
Every patrol stop is GPS-verified, so a board member in Brambleton or a property manager in Ashburn can see when the officer arrived and left. Officers wear Class A uniform on standing posts, and the supervisor on duty answers the 24/7 line directly.
Long-distance routes in western Loudoun get planned around drive time between stops. We will tell you honestly how many checks a night a single car can make on rural roads before you sign anything.
Events and seasonal work in Loudoun
Loudoun events usually need officers for parking, entry, and crowd flow. Wineries and breweries along Route 9 and Route 15, festivals in downtown Leesburg, and corporate gatherings at One Loudoun all draw crowds that outgrow a venue's own staff.
We size event teams after learning the expected headcount, the number of gates, and whether alcohol is served.

A Loudoun engagement begins with a site walk at your property, usually led by someone from our Sterling office. After the walk you receive a written proposal covering posts, hours, patrol frequency, and the officer profile we recommend.
