Router Firmware

NG Firewall Firmware Distribution

Router hardware has evolved and improved over the years, but its firmware remains stuck in the dark ages when it comes to security, network traffic visibility and control. Recognizing the inherent limitations in popular commercial routers, Untangle set about making a radical new OS for Wi-Fi routers based on its popular, broadly installed and easy-to-use NG Firewall product. NG Firewall is now available to be flashed onto the Linksys WRT1900ACS.

Cost-Effective Solutions for Small Networks

The biggest challenge facing small networks isn’t necessarily even security: it’s the lack of visibility into and control over the traffic. This is where Untangle can help. Unlike pre-installed firmware on off-the-shelf wireless routers, Untangle NG Firewall logs traffic for rich, robust reporting into every facet of what’s happening online: sites users are visiting, uninvited guests jumping on the wireless network, and the newest IP-enabled gadget phoning home. NG Firewall allows users to create rules for managing access to websites, applications, and content based on criteria like device, user, time of day, day of week and more. You can see the effect of those rules through drill-down reports that can be monitored via the 360° Dashboard, a single pane of glass view into what’s happening on the network.

Perfect for:

  • Small business
  • Branch offices
  • Retail/franchise locations
  • Home offices
Or anyone looking for cost-effective security at the gateway!
