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

"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 product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."
"I have found this solution has more plugins than other competitors which is a benefit. You are able to attach different plugins to the security scan to add features. For example, you can check to see if there are any payment systems that exist on a server, or username and password brute force analysis."
"I personally love its capability to automatically and accurately detect vulnerabilities. So, I would say it is the Burp scanner that is THE most powerful, valuable, and an awesome feature."
"The extension that it provides with the community version for the skills mapping is excellent."
"Enables automation of different tasks such as authorization testing."
"The feature that we have found most valuable is that it comes with pre-set configurations. They have a set of predefined options where you can pick one and start scanning. We also have the option of creating our own configurations, like how often do the applications need to be scanned."
"There is no other tool like it. I like the intuitiveness and the plugins that are available."
"The most valuable feature is the application security. It also has a reasonable price."
"It helps in API testing, where manual intervention was previously necessary for each payload."
 

Cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."
"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."
"We wish that the Spider feature would appear in the same shape that it does in previous versions."
"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."
"As with most automated security tools, too many false positives."
"The one feature that I would like to see in Burp is active scanning of REST based web services. A lot of organizations are providing APIs to access their services to support different business models like SaaS. Scanning these APIs is still a challenge for many security product companies."
"We'd like to have more integration potential across all versions of the product."
"I am from Brazil. The currency exchange rate from a dollar to a Brazilian Real is quite steep. It is almost six to one. It would be good if it can be sold in the local currency, and its price is cheaper for us."
"I would like to see a more optimized solution, as it currently uses a lot of CPU power and memory."
"The scanner and crawler need to be improved."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"There are different licenses available that include a free version."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."
"The platform's pricing is reasonable."
"For a country such as Sri Lanka, the pricing is not reasonable."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"We have one license. The price is very nominal."
"PortSwigger is reasonably-priced. It's fair."
