What SSV Software Systems does

SSV Software Systems GmbH is a privately held German embedded systems company founded in 1981 and headquartered in Hannover, where it develops, manufactures, and markets microcomputer modules, assemblies, and systems for industrial and process automation. Its portfolio spans the sensor-to-cloud stack: a family of LTE and Ethernet gateways (IGW/9xx series) and remote maintenance gateways (RMG/941, RMG/941C), a 32-bit ARM-based System-on-Module (eDNP/8331) delivered with Debian Linux and licensable as IP, analog/digital I/O extensions (IO/5640, IO/5640-DS), security accessories (SEC/1 dongle), and software frameworks including the SSV/WebUI web interface framework and the SSV Field Data Engine for multi-protocol data collection (TCP, Modbus, OPC UA, IEC 60870-5, M-BUS, VHPready, MQTT). The company also offers a Wireless Remote Development (WRD) solution with CRA-compliant OTA updates and an AI-based embedded IDS for OT network cybersecurity.

The company's revenue model combines hardware sales (gateways, modules, starter kits, accessories), software licensing (Node-RED nodes, Embedded IDS, OPC UA/Modbus/IEC protocol implementations, firmware), and custom development services (Wireless IoT Retrofit, Smart Factory Sensor, embedded DevOps). It goes to market through direct enterprise sales via a hotline and contact form, complemented by trade show presence (embedded world, SPS, Elektronik Solution Days), webinars, and a developer community (forum, wiki, GitHub). Customers are industrial automation and machine/plant engineering firms implementing Industry 4.0, IoT connectivity, secure remote maintenance, and predictive maintenance applications; the company serves a worldwide customer base from its Hannover headquarters, is ISO 9001:2015 certified, and is co-founder of the M2M Alliance and VHPready associations and a full member of the OPC Foundation.
