TAS

What TAS does

TAS (Telefonbau Arthur Schwabe GmbH & Co. KG) is a German, family-owned manufacturer and systems integrator of security and communication technology headquartered in Mönchengladbach. Founded in 1924, the company develops, produces, and services alarm transmission equipment (TAS-Link IV and TAS-Link III), security routers (SIRO-Port with BSI-hardened OS), alarm servers (ARUTEL and the cloud-hosted ARUTEL-Portal), and integrated alarm/building management platforms (TARSOS, WinGuard-based PSIM). Its portfolio covers fire alarm, intrusion and panic alarm, video surveillance with analytics, access control, voice alarm/conference (KOMMUTEL, ULE 614), patient call systems, and personal emergency response, all delivered with VdS, BHE, DIN EN ISO 9001, DIN 14675, TISAX, and related German/European certifications.\n\nThe business operates as a vertical-focused enterprise security provider, with primary segments in financial services, gas stations, retail, and military/government, plus secondary exposure to stadiums, data centers, and critical infrastructure. Go-to-market is direct enterprise sales supported by a nationwide field service technician network, with dedicated account managers per vertical and branch offices (e.g., Niederlassung NordOst). Revenue is generated through a mix of proprietary hardware sales, project-based system integration, and a growing subscription/managed-services tail anchored by the TAS Secure Platform, the ARUTEL-Portal cloud, and the TAS Service Center hotline/remote-maintenance offering.\n\nTAS functions as a certified German integrator-of-record across multi-vendor estates — partnerships with Axis, Milestone, Avigilon, SimonsVoss, Esser/Honeywell, Hekatron, Advancis (WinGuard), Klüh Security, and others — and pairs this with proprietary, in-house-designed transmission and alarm infrastructure. Its first disclosed international expansion was a 2025 partnership with Egyptian industrial solutions provider Diverse Supplies to enter North Africa, complemented by R&D initiatives (KIRaPol.5G radar-based public-space surveillance, Wärmewende Nordwest building-monitoring platform) that hint at platform extension beyond pure security into 5G perimeter detection and energy-sector building management.
