A Legacy of IDC Innovation Since 1975
Founded in 1975 in Stora Sundby, Sweden, Westermo began with Tore Andersson’s isolated line driver, extending serial communications to 18 km - a breakthrough in early IDC. Evolving from Westermo Teleindustri, they pioneered industrial modems, introduced the ED-10 Ethernet converter in 2000, and became a rail IDC leader with Viper solutions. The 2019 Neratec acquisition bolstered their wireless portfolio, while NNN Group’s 2016 ownership fueled R&D. With 200+ employees and millions of ports deployed, Westermo’s 50-year legacy, endorsed by IEC and EN standards, cements their IDC leadership.
Positioning in the Industrial Data Communications Field
In the IDC field, Westermo is a cornerstone, enabling secure, high-speed data communications across distributed industrial networks. Their switches and routers facilitate real-time data aggregation, supporting protocols like IEC 61850 for energy applications and Profinet for manufacturing. WeOS’s cybersecurity features - network segregation, IEC 62443 compliance - protect against threats, while eSIM/eUICC routers enable dynamic, global connectivity.
Westermo positions itself as the “IDC backbone,” bridging legacy and modern systems for OT-IT convergence. In rail, their solutions power train-to-ground IDC, reducing latency to microseconds. In utilities, they enable remote SCADA, cutting maintenance costs. As IDC evolves with AI and 5G, Westermo’s rugged, protocol-agnostic solutions drive adoption, ensuring data integrity across industries.
