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

"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."
"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."
"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."
"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."
"I rate PortSwigger Burp Suite Professional ten points out of ten."
"The most valuable feature of PortSwigger Burp Suite Professional is the Burp Intruder tool."
"We found PortSwigger to be the best match for our business."
"This is a very nice tool and anybody can use it, from beginner to expert level."
"The solution is stable."
"This is a standard tool in this industry and anybody who is doing application security testing should be aware of it."
"I highly recommend it because everybody in Web Applications Security is using it."
"PortSwigger Burp Suite Professional has an intercept tab that helps us to scan our APIs, set the response, and request errors."
 

Cons

"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."
"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."
"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."
"Scanning needs to be improved in enterprise and professional versions."
"The technical support team's response time is mostly delayed and should be improved."
"One area that can be improved, when compared to alternative tools, is that they could provide different reporting options and in different formats like PDF or something like that."
"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."
"There is room for improvement in composition and improvements could be made."
"In the Professional version, we cannot link it with the CI/CD process."
"The price could be better. The rest is fine."
"The initial setup is a bit complex."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"PortSwigger Burp Suite Professional is expensive compared to other tools."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."
"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."
"This is a value for money product."
"At $400 or $500 per license paid annually, it is a very cheap tool."
"It's a lower priced tool that we can rely on with good standard mechanisms."
"For a country such as Sri Lanka, the pricing is not reasonable."
