Your router handles the connection. It doesn't handle the threats riding along with it. This add-on plugs intrusion prevention and web filtering directly into your existing Cradlepoint NetCloud Essentials router, so you're not running a second appliance or hoping the default settings hold up. Three-year term. One subscription to manage. Works with E3XX, E3XXX, R19XX and IBR17XX series units. If your router's already on site and the NetCloud Essentials service is active, this is the layer you've been missing. Add it to your cart and we'll confirm compatibility against your exact unit before it ships
