Kastle

What Kastle does

Kastle Systems, founded in the early 1970s and headquartered in Falls Church, Virginia, is a privately held managed security services provider specializing in physical security for commercial real estate, multifamily residential, office enterprises, education, and government facilities in the United States (with international operations in Australia). The company delivers security as an integrated subscription service rather than as discrete product sales — designing, installing, monitoring, and maintaining access control, video surveillance, visitor management, and parking systems on a single cloud-based platform unified through the myKastle management portal.

The underlying technology stack combines cloud-based access control with mobile credentials (KastlePresence for commercial tenants, KastleResident for multifamily), AI-powered cloud video surveillance (KastleVideo, Kastle Video Search, Kastle VideoGuarding remote monitoring), video intercom (KastleVideocom), visitor management (KastleVisitor), parking (KastlePark), and business intelligence (myCompass, Kastle Insights). Kastle is a founding member of the Aliro 1.0 interoperability standard and was the first to deploy Aliro-certified mobile credentials across Apple Wallet, Google Wallet, and Samsung Wallet simultaneously. AI capabilities include patented video processing algorithms, facial recognition, license plate recognition, anomaly detection, and predictive occupancy analytics built on data from 60,000 cameras, 350 million monthly detections, and 1.8 million global users.

Kastle's business model is a managed-services subscription with monthly recurring fees covering design, installation, 24/7 monitoring, maintenance, and software updates; pricing is quote-based and varies by site count and service scope. The company reports average client relationships exceeding 10 years, serves 10,000+ sites and 60,000+ businesses across 47 states, and operates 20 US regional offices plus three Australian offices for localized delivery. Distribution combines direct enterprise field sales — recently restructured by a CRO hired from Motorola Solutions — with deep integrations into building management platforms (CBRE Host, RealPage), identity providers (Okta, Active Directory), and the five largest global elevator manufacturers. Customers span commercial real estate owners and operators (Brookfield, CBRE, Hines, Cushman & Wakefield, JBG SMITH), law firms (49 of the AmLaw 100), multifamily operators (AvalonBay, Kimco, Bozzuto), private equity (Blackstone, Carlyle), government (FISMA-compliant deployments), and education. The company reports multiple consecutive years of profitable growth and ranks in the Top 10 of the 2025 SDM 100.
