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.

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

"Simple and straightforward GUI."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"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."
"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."
"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."
"It was easy to learn."
"Some of the extensions, available using Burp Extender, are also very good and we have found issues by using them."
"The free version is one of the best proxy tools for manual testing."
"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."
"PortSwigger Burp Suite Professional has an intercept tab that helps us to scan our APIs, set the response, and request errors."
"The Repeater and the BApp extensions are particularly useful. Certain extensions, such as the Active Scan extensions and the Autoracer extension, are very good."
"It offers very good accuracy. You can trust the results."
"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."
 

Cons

"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."
"You can't implement proprietary ciphering algorithms, nor can you modify protocol models if you need to test customized public protocols."
"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."
"There could be an improvement in the API security testing. There is another tool called Postman and if we had a built-in portal similar to Postman which captures the API, we would be able to generate the API traffic. Right now we need a Postman tool and the Burp Suite for performing API tests. It would be a huge benefit to be able to do it in a single UI."
"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."
"One thing that is not up to the mark in PortSwigger is web application testing. I found some issues with its performance and reporting. They should work on these and give us a better outcome."
"The solution’s pricing could be improved."
"The Burp Collaborator needs improvement. There also needs to be improved integration."
"There needs to be better documentation provided."
"The technical support team's response time is mostly delayed and should be improved."
"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."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"We are using the community version, which is free."
"We have one license. The price is very nominal."
"The pricing of the solution is reasonable. We only need to pay for the annual subscription. I rate the pricing five out of ten."
"There is no setup cost and the cost of licensing is affordable."
"They should reduce the license cost a little bit. It is $400 per user, and it would be better if they could reduce the licensing fee."
"I rate the pricing a four out of ten."
"For a country such as Sri Lanka, the pricing is not reasonable."
