mGuard RS2000 and RS4000 provide defense-in-depth cybersecurity with all-in-one firewall, VPN and routing capability. With new metal housing, they operate in -20 to 60 °C range. Users can save a configuration on an SD card in one mGuard and insert that card into a new mGuard to duplicate settings. Configured with an SD card, the settings will remain, even if the SD card is removed.
