Security teams on the ground across the Washington metro

Kastle has protected buildings across the Washington, DC, metro for decades. Our teams know the area's building stock, from downtown DC office towers to communities and campuses in Arlington, Alexandria, Bethesda, Tysons, and Reston. The local picture is improving: robberies across the District fell 39% in 2024 compared to 2023. A safer District helps, but the front door and garage of any one building still need watching, which is exactly what a nearby team and around-the-clock monitoring provide.

One provider, every stage

The physical security company that owns your whole system

Most security programs in Washington, DC, fail between vendors, not the hardware. One company installs, another monitors, a third maintains, and no one owns the outcome. Kastle removes those seams by owning the full lifecycle. We design, install, monitor, and maintain your system ourselves. Kastle has run this managed model for over 50 years, protecting more than 10,000 properties and 60,000+ businesses across the United States and Australia. In the District's mixed-use market, that ownership leaves no gap where accountability should be.

Site assessment and system architecture for physical security in Washington, DC

A useful security design starts from where a building is actually exposed. Kastle security architects walk your Washington, DC, facility, map entry points, sightlines, and after-hours risk, then design a system around what they find. That matters here because DC violent crime reached a 30-year low in 2024, according to the U.S. Attorney's Office for the District of Columbia, yet property-directed threats at lobbies, garages, and loading docks remain a daily concern. We design for the risks your building faces, then own what we install.

Design begins with an on-site walk of your building.
Every recommendation traced to a risk found on site.
Systems built on open architecture that scales with you.

Frequently asked questions

What does a physical security company provide?

A physical security company protects people, property, and assets from threats like unauthorized access, theft, and vandalism. In practice that means access control, video, monitoring, and visitor management working together. Kastle delivers all of it as one managed service across Washington, DC, handling design, installation, monitoring, and upkeep so your team is not coordinating separate vendors.

What is included in commercial physical security services?

Most commercial programs combine access control at entry points, video surveillance, alarm monitoring, and visitor management, plus the ongoing support that keeps it all running. The difference is who owns those pieces. With Kastle, one accountable partner runs the full set, so there is a single point of contact when anything needs attention.

Can a physical security provider create a security plan for a business?

Yes. A good plan starts with an on-site assessment, not a product list. Kastle security architects walk your Washington, DC facility, map where it is exposed, and design a system around those specific risks. Because the same partner then installs and supports what it designed, the plan holds up over time instead of drifting as vendors change.

Can physical security services be provided for temporary events?

Can physical security providers manage visitor and employee access?

Can businesses request security services for multiple locations?

Yes. A single managed platform is well suited to multi-site operations across the Washington, DC metro, from Arlington and Alexandria to Bethesda and Reston. You manage access, video, and alerts for every location through one relationship, with one partner accountable for all of them, rather than a different vendor in each building.
