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

"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."
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"The stability of this product is great; we tested it under multiple constraints and even on cloud services it is absolutely stable."
"The most valuable feature is Burp Collaborator."
"It helps in API testing, where manual intervention was previously necessary for each payload."
"It's good testing software."
"The extension that it provides with the community version for the skills mapping is excellent."
"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 have found the best features to be the performance and there are a lot of additional plugins available."
"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."
"I highly recommend it because everybody in Web Applications Security is using it."
 

Cons

"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"The solution isn't too stable; the fundamentals of it make it difficult to use."
"Currently, the scanning is only available in the full version of Burp, and not in the Community version."
"There is not much automation in the tool."
"The solution doesn't offer very good scalability."
"There is a certain amount of lead time for the tickets to get resolved."
"Sometimes the solution can run a little slow."
"There is room for improvement in composition and improvements could be made."
"If your application uses multi-factor authentication, registration management cannot be automated."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"We have one license. The price is very nominal."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"This is a value for money product."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"There is no setup cost and the cost of licensing is affordable."
"It is a cheap solution, but it may not be cheaper than other solutions."
"PortSwigger is reasonably-priced. It's fair."
"I rate the pricing a four out of ten."
