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.

Dedicated browser and repeater have improved my proxy testing and manual vulnerability checks
I'm hoping perhaps for something to make it easier, such as to define things where if a message or a response is such and such, automatically make a request that is such and such. Perhaps something like this because otherwise, nowadays we have to do it manually. Perhaps they can automate it a bit more. Perhaps they could add some automation to things, to see what we do manually, which it has the tools to do manually, and perhaps enable with a click of a button to do things automatically. I'm not too sure which, but I'm sure they can from a product management point of view, do things that we need to do two, three, or four steps manually regarding specific testing. For instance, we want to check something specific if it's this or if it's that. Perhaps to define it once and have it more automatic, perhaps.

Quotes from Members

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

Pros

"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"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."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"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, and because of that, we can eliminate a lot of unwanted test cases so we can execute the tests and complete them very quickly."
"Simple and straightforward GUI."
"If you compare it to more expensive tools like WebInspect or IBM AppScan, you'll realize that, at a very low cost, Burp Suite can provide good results."
"I am impressed with the tool's detailed analysis for penetration testing. AppScan can give only visibility, but it can't do the PT part. But the PortSwigger Burp Application can do both, and it gives much more visibility on the PT rating."
"The tool provides complimentary services. It allows you to add a lot of extensions, and you can get extensions quite often. It is quite a flexible application."
"This solution has done a lot to improve our organization, allowing us to be proactive and solve issues before our external auditors find them."
"The solution has a great user interface."
"I have found the best features to be the performance and there are a lot of additional plugins available."
"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."
"This is a very nice tool and anybody can use it, from beginner to expert level."
 

Cons

"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"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."
"The professional edition of Burp Suite provides some automated pen-testing scripts to detect application vulnerabilities, like SQL injection, XSS, etc. However, this component is not extremely useful."
"The interface for the automatic scan can be improved because it is easy for technical users, but the business users have trouble with it."
"Spidering large websites can use a lot of memory and might result in a crash on systems with lower RAM."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"There should be a heads up display like the one available in OWASP Zap."
"The solution doesn't offer very good scalability."
"Even though I started working with PortSwigger Burp Suite Professional, I think I may have run the Scanner once, but I prefer to run ZAP because I'm more used to it and I think it checks many more vulnerabilities."
"In general, there's not much to complain about but the stability of the tool is not good enough."
