RD (Rogue Detection) Sensor is a part of ESET Remote Administrator designed to find computers on your network. It provides a convenient way of adding new computers to ESET Remote Administrator without the need to find and add them manually. Every computer found on your network is displayed in the Web Console and added to the default All group. From here, you can take further actions with individual client computers.
RD Sensor is a passive listener that detects computers that are present on the network and sends information about them to the ERA Server. The ERA Server evaluates whether the PCs found on the network are unknown or already managed.
