Effective vulnerability identification enhances security scans but AI-driven enhancements are needed
OWASP is only meant for two or three different types of scans. It is a tool which will scan the code for security for vulnerabilities We were able to convince the customers to really remove those rules when GitLab was able to show the results. Customers should be aware that GitLab is not just a…

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

"The application scanning feature is the most valuable feature."
"The product discovers more vulnerabilities compared to other tools."
"It scans while you navigate, then you can save the requests performed and work with them later."
"​It has improved my organization with faster security tests.​"
"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."
"OWASP is quite matured in identifying the vulnerabilities."
"Simple and easy to learn and master."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"The way they do the research and they keep their profile up to date is great. They identify vulnerabilities and update them immediately."
"The Repeater and the BApp extensions are particularly useful. Certain extensions, such as the Active Scan extensions and the Autoracer extension, are very good."
"The solution has a limited range of functions, which is good for small companies. This is because, in small companies, websites are less complex. They also have single services which makes the solution good enough for them. However, the most advantageous aspect of the solution is its affordable price."
"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."
"It is a time-saver application."
"The most valuable feature of PortSwigger Burp Suite Professional is the dashboard. It is very informative and you can receive all the information you need in one place. It's clear, well-defined, and organized. Anybody without any cybersecurity can use it."
"I rate PortSwigger Burp Suite Professional ten points out of ten."
"The most valuable features of PortSwigger Burp Suite Professional are its ease of use and its cost efficiency."
 

Cons

"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"The port scanner is a little too slow.​"
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"OWASP Zap needs to extend to mobile application testing."
"Sometimes, we get some false positives."
"The product reporting could be improved."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"The technical support team must be proactive."
"The technical support team's response time is mostly delayed and should be improved."
"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."
"One area that can be improved, when compared to alternative tools, is that they could provide different reporting options and in different formats like PDF or something like that."
"In the Professional version, we cannot link it with the CI/CD process."
"Currently, the scanning is only available in the full version of Burp, and not in the Community version."
"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."
"The solution’s pricing could be improved."
"BurpSuite has some issues regarding authentication with OAT tokens that need to be improved."

"The tool is open source."
"The solution’s pricing is high."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."

First things first both are having their own merits, however in my personal experience ZAP can replace your burpsuite for sure considering the License. Also as the latest ZAP versions are covering more advanced techniques and spidering patterns with lots of options in it, it is worth considering ZAP. However remember that burpsuite from latest versions with inbuilt chromium and it's emerging plugin support (Installable jars) you can use burp to the fullest and you can keep it as a swiss knife for your web and app pentesting. Couple of extensions in burp pro are interesting especially the race condition one. I always prefer using Burp and at instances I go with ZAP.
