Product security tests for switches and router sections

Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install. What I see in the documentation isn't that. Even if something doesn't malfunction, sometimes it is hard to install and execute. The product needs video documentation. This would help a lot more.

It's buggy and seems to try to do too many things, but having this on a USB drive has been valuable.

I tried to install this on numerous systems and eventually, with help, I got it running. It needs far too many dependencies installed and there's too much messing about to be of much use. Once running, it's buggy and begs the question can it be relied upon? Even within Kali it reports website time-outs, yet Zap or Burp are able to do a successful scan. I wanted this to work so much and be able to use it as an additional check of my results but have now binned it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"ROI was 100%. Since there are no product suites available that provide the level of testing available with Codenomicon, the development, quality and security assurance departments know that the investment was correct."

"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

"Simple and straightforward GUI."

"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."

"The best free software for pen testing web applications."

Cons

"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."

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."

"It requires understanding the Defensics protocol."

"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."

"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."

"Unfortunately, once you get around the seemingly strict set of pre-requisites to install it, it is incredibly buggy."

Pricing and Cost Advice

"Licensing is a bit expensive."
