Key learnings from peers

Valuable Features

  • "The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
  • "Whatever the test suit they give, it is intelligent. It will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."
  • "We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

Room for Improvement

  • "Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
  • "It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."
  • "Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."

Pricing

  • "Licensing is a bit expensive."
