Open source testing tool empowers manual activities and has room to improve integration and reporting features

The improvement that has to be done for APIs focuses on manual activities where the feature exists, but it is not at the same level as what Burp Suite does with intercepting and tools such as Postman, so it needs improvement. There are limitations with authentication levels, particularly with form-based and cookie-based authentication. However, overall, we are satisfied with OWASP Zap as there are no major issues, and improving the scan engine could be beneficial. When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking.

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.

"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool and at the same time give a comprehensive report with great confidence to the client for helping them in their go-live decision."

"The HUD is a good feature that provides on-site testing and saves a lot of time."

"The solution is good at reporting the vulnerabilities of the application."

More OWASP Zap pros

"PortSwigger Burp Suite Professional is one of the best user-friendly solutions for getting the proxy set up."

"The way they do the research and they keep their profile up to date is great. They identify vulnerabilities and update them immediately."

"The intercepting feature is the most valuable."

"The feature that we have found most valuable is that it comes with pre-set configurations, with a set of predefined options where you can pick one and start scanning, and we also have the option of creating our own configurations, such as how often the applications need to be scanned, along with good reporting and dashboards that integrate well with other task management applications we are using."

"The documentation needs to be improved because I had to learn everything from watching YouTube videos."

"The solution is unable to customize reports."

"The reporting needs to be improved; it is very bad."

"The number of false positives need to be reduced on the solution."

"One more thing they can improve is that despite having a good architecture, it needs a lot of specification."

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.
