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.

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

"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."
"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."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"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."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"Simple and straightforward GUI."
"This solution provides a very good mechanism for fixing interval time; for example, we can create a schedule, and the schedule runs on time, PortSwigger Burp Suite does not hamper the node of the server and does not shut down the server if it is running, it is quite fast and easy to install as well, and it is also a budget-friendly tool."
"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."
"I highly recommend it because everybody in Web Applications Security is using it."
"The solution is quite helpful for session management and configuration."
"When we compare it to other programs that we have such as OWAP Zap, we found Burp to be more suitable."
"I find the attack model quite amazing, where I can write my scripts and load my scripts as well, which helps quite a bit. All the active scanning that it can do is also quite a lot helpful. It speeds up our vulnerability assessment and penetration testing. Right now, I am enjoying its in-browser, which also helps quite a bit. I'm always confused about setting up some proxy, but it really is the big solution we all want."
"The most valuable feature of PortSwigger Burp Suite Professional is the Burp Intruder tool."
"PortSwigger Burp Suite Professional is superior in quite a few options."
 

Cons

"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."
"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."
"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."
"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."
"If we're running a huge number of scans regularly, it slows down the tool."
"The use of system memory is an area that can be improved because it uses a lot."
"PortSwigger Burp Suite Professional could improve the static code review."
"There is a lot to this product, and it would be good if when you purchase the tool, they can provide us with a more extensive user manual."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"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."
"There is not much automation in the tool."
"Currently, the scanning is only available in the full version of Burp, and not in the Community version."
