Ixia has one flaw, which is that they do not print the license code on the paper licenses that are shipped to the customers. This impacts technical support because once you have to contact the vendor, they begin asking for that number. It's something that should be upfront, part of the order processing, and readily available. Also, when we do the installation or our partner does it, then when we need to start calling people, the number is not available. It's not something that can be easily addressed over the phone because it is long, with a lot of letters in it. There are features available in the Threat Simulator that are not available in the main product.
