Easy access via API's with zero coding required (only need Java). I have nothing negative in this software at all yet! The pricing model makes sense also as it includes some basic features like vlans/vpn which are included free by default if you go above 100Gbps speeds but require licensing otherwise. This was our solution when we had problems finding solutions within Cisco hardware products due too high costs associated wth them not being flexible enough nor configurable through their own GUI tools / CLI etc., especially since they were tied into ASR 1000 series boxes where there wasn't much flexibility anyway compared say eith Juniper SRX-OS400 switches or other non cisco devices suchas Qfx24xxsensorsetups.. I like best about this software its ease in use (its easy) it runs fast compared with other softwares out there as well you don't have any issues when using their product at all! Nothing i dislike but if u want something simple then give them some consideration because they are doing work good enoughtly!! I think we should try another one just before going back again. We need more options now days especially where speed matters most.
