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.

Test assurance improves compliance and products with good performance
The user interface could be improved to facilitate easier navigation. The most significant issue I encounter with the solution is the user interface. It would be beneficial if I could remain on one screen most of the time. Even if the system navigates me to another screen, it should effectively return me to the main screen.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I am impressed with the tool's detailed analysis for penetration testing. AppScan can give only visibility, but it can't do the PT part. But the PortSwigger Burp Application can do both, and it gives much more visibility on the PT rating."
"Burp is the best web application penetration testing tool that I have ever used."
"The initial setup is simple."
"The solution is stable."
"The solution has a pretty simple setup."
"BurpSuite helps us to identify and fix silly mistakes that are sometimes introduced by our developers in their coding."
"This solution has done a lot to improve our organization, allowing us to be proactive and solve issues before our external auditors find them."
"I find all the features of PortSwigger Burp Suite Professional most useful, particularly the AI enhancement for results and follow-up for retests."
"CyberFlood is flexible."
"CyberFlood is bundled and basic, but it's still powerful and easy to use, and I would recommend it, especially for beginners."
"The feature I find most valuable is the traffic generator."
"Our customers use it to check for unauthorized file transfer."
"The testing compliance feature is particularly impressive."
"CyberFlood's best features are its user-friendliness and scheduling function."
"If any customer doubts their existing network security policy this is a perfect product to analyze their network security and even existing processes."
 

Cons

"BurpSuite has some issues regarding authentication with OAT tokens that need to be improved."
"I would like to see the return of the spider mechanism instead of the crawling feature. Burp Suite's earlier version 1.7 had an excellent spider option, and it would be beneficial if Burp incorporated those features into the current version. The crawling techniques used in the current version are not as efficient as those used in earlier versions."
"The solution’s pricing could be improved."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"Mitigating the issues and low confluence issues needs some improvement. Implementing demand with the ChatGPT under the web solution is an additional feature I would like to see in the next release."
"Sometimes the solution can run a little slow."
"Spidering large websites can use a lot of memory and might result in a crash on systems with lower RAM."
"We'd like to have more integration potential across all versions of the product."
"The user interface could be improved to facilitate easier navigation."
"CyberFlood's accessibility and support for multiple browsers could be better."
"The initial setup is not straightforward and can be quite challenging."
"The solution needs more ports, more speed, and more gigabytes."
"Sometimes, when you configure parameters the hardware can't run, it will get stuck at those points without telling you what happened. It would be helpful if the error reporting provided more details about why the test setting is not running. It would be nice if there were a space in the hardware module for you to add some external hardware for more rigorous testing."
"I would also like to see updates on a more frequent schedule."
 

Pricing and Cost Advice

"We are using the community version, which is free."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."
"Burp Suite is affordable."
"It's a lower priced tool that we can rely on with good standard mechanisms."
"There is no setup cost and the cost of licensing is affordable."
"The pricing of the solution is reasonable. We only need to pay for the annual subscription. I rate the pricing five out of ten."
"The platform's pricing is reasonable."
"There are different licenses available that include a free version."
"CyberFlood is reasonably priced."
