Secure IoT Gateway

When it comes to Industry 4.0 and IoT, the communication of the local devices among each other using local or wide area networks can be associated with a high level of complexity. Especially securing the network connections of IoT is difficult. The Secure IoT Gateway simplifies the complexity of securing the connection of devices to a network, coming with a Network Cockpit Application for configuring and monitoring the system.

The Secure IoT Gateway is made up of a synergy of components

The Secure IoT Gateway is a special case among the use cases of the LEGaTO project, as its general objective is not energy efficiency but to simplify the complexity of communication of local devices to a network. Therefore, it supports other use cases to achieve their goals by reducing the complexity of security for them.

Particularly, the Secure IoT Gateway supports the Smart Home use-case by adding an extra security layer.


In order to test the system in a real-world environment, the Secure IoT Gateway was installed into the KogniHome research flat in Bielefeld. KogniHome is a project that develops and showcases new smart home technologies that allow technology-assisted living for all age generations and people with disabilities.

The Secure IoT Gateway can make use of almost any hardware, but runs very efficiently on the LEGaTO Microserver Platform. Software wise, open source tools are used to create the secure tunnels and firewalls.
