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 highly recommend it because everybody in Web Applications Security is using it."
"The crawling capability is excellent."
"There is no other tool like it. I like the intuitiveness and the plugins that are available."
"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."
"The solution helped us discover vulnerabilities in our applications."
"The solution is quite helpful for session management and configuration."
"PortSwigger Burp Suite Professional is one of the best user-friendly solutions for getting the proxy set up."
"The automated scan is what I find most useful because a lot of customers will need it. Not every domain will be looking for complete security, they just need a stamp on the security key. For these kinds of customers, the scan works really well."
"Our customers use it to check for unauthorized file transfer."
"If any customer doubts their existing network security policy this is a perfect product to analyze their network security and even existing processes."
"The testing compliance feature is particularly impressive."
"CyberFlood is flexible."
"The feature I find most valuable is the traffic generator."
"CyberFlood is bundled and basic, but it's still powerful and easy to use, and I would recommend it, especially for beginners."
"CyberFlood's best features are its user-friendliness and scheduling function."
 

Cons

"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."
"The solution’s pricing could be improved."
"There were a lot of false positives there, and we used to spend a lot of time, like, for security reasons, reproducing those bugs for the development team to fix it."
"The tool is very expensive."
"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."
"The reporting needs to be improved; it is very bad."
"The solution lacks sufficient stability."
"Scanning needs to be improved in enterprise and professional versions."
"The user interface could be improved to facilitate easier navigation."
"The solution needs more ports, more speed, and more gigabytes."
"CyberFlood's accessibility and support for multiple browsers could be better."
"I would also like to see updates on a more frequent schedule."
"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."
"The initial setup is not straightforward and can be quite challenging."
 

Pricing and Cost Advice

"We are using the community version, which is free."
"PortSwigger is a bit expensive."
"Burp Suite 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."
"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."
"For a country such as Sri Lanka, the pricing is not reasonable."
"Pricing is not very high. It was around $200."
"CyberFlood is reasonably priced."
