What ATN Beveiliging does

ATN Beveiliging is a Dutch private security services company headquartered in Nieuw-Vennep (Pesetaweg 39, 2153 PJ), operating as an integral member of the Castellum Security Collective (Castellum Security B.V., registered in Rijsenhout). The company delivers an integrated security portfolio covering seven core service lines: Brandbeveiliging (fire safety), Inbraakbeveiliging (intrusion detection), Camerabeveiliging (CCTV, including PTZ and thermal cameras), Toegangscontrole (access control with tag, pass, smartphone, and biometric recognition), Mobiele surveillance (mobile patrol), Video Toezicht Centrale (24/7 video monitoring), and Nood- en vluchtwegverlichting (emergency and escape route lighting). Its technology stack combines conventional detection hardware, dome/bullet/PTZ/thermal cameras, biometric access readers, and a central Castellum-branded alarm and video monitoring centre (PAC/VTC) where human centralists verify alarm-triggered footage in real time and dispatch response.

ATN serves Dutch business, government, education, industry, logistics, and residential customers through a consultative direct enterprise field-sales model. Each engagement starts with a risk analysis and results in a tailored security plan followed by in-house design, installation, and maintenance. The company operates exclusively in the Netherlands, with named projects spanning Rotterdam, Amsterdam, Scheveningen, Eindhoven, and national chain accounts. It is led by Algemeen Directeur Ronald Groen, and its parent group Castellum Security B.V. holds ISO 27001 certification covering information security management.

ATN makes money through a mix of one-time hardware and installation revenue and recurring subscription revenue. Commercial models include outright purchase, equipment rental (huur), full-service subscriptions covering 24/7 availability, defect repairs, software maintenance, and on-site service visits, and 12-month auto-renewing monitoring subscriptions (PAC/VTC). Mobile surveillance is offered as a recurring or scheduled patrol service. Pricing is not publicly disclosed and is set through custom quotes. Distribution is exclusively direct — field sales, phone, website contact form, plus a 24/7 storingsdienst (emergency) line — with cross-referrals flowing through the Castellum Security Collective network. The Castellum shared careers platform (recruitee.com) is used for recruiting technicians, centralists, and specialists.
