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.

Quotes from Members

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

Pros

"It updates repositories and libraries quickly."
"The solution has tightened our security."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"Automatic updates and pull request analysis."
"Simple to use, good user interface."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."
"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."
"The tool provides complimentary services. It allows you to add a lot of extensions, and you can get extensions quite often. It is quite a flexible application."
"The suite testing models are very good. It's very secure."
"PortSwigger Burp Suite does not hamper the node of the server, and it does not shut down the server if it is running."
"I have found the best features to be the performance and there are a lot of additional plugins available."
"For pentesting scenarios, this is the number one tool. It can capture the request, and there are so many functions that are very good for that. For example, a black box satellite host."
"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."
"Enables automation of different tasks such as authorization testing."
"It offers flexibility, macros, and features to reduce the effort required for authenticated sessions."
 

Cons

"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"Deployment is somewhat complicated."
"It doesn't run on absolutely every operating system."
"Lacks resources where users can internally access a learning module from the tool."
"OWASP should work on reducing false positives by using AI and ML algorithms."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."
"The price could be better. The rest is fine."
"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."
"The Auto Scanning features should be updated more frequently and should include the latest attack vectors."
"The use of system memory is an area that can be improved because it uses a lot."
"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."
"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."
"The biggest improvement that I would like to see from PortSwigger that today many people see as an issue in their testing. There might be a feature which might be desired."
"The scanner and crawler need to be improved."
 

Pricing and Cost Advice

"The solution’s pricing is high."
"This solution is open source and free."
"This is an open-source solution and can be used free of charge."
"OWASP Zap is free to use."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"It is highly recommended as it is an open source tool."
"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
"This app is completely free and open source. So there is no question about any pricing."
"It has a yearly license. I am satisfied with its price."
"Licensing costs are about $450/year for one use. For larger organizations, they're able to test against multiple applications while simultaneously others might have multiple versions of applications which needs to be tested which is why we have the enterprise edition."
"This is a value for money product."
"I rate the pricing a four out of ten."
"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."
"There are different licenses available that include a free version."
"We are using the community version, which is free."
"At $400 or $500 per license paid annually, it is a very cheap tool."

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.

Yes OWASP ZAP is a good option as it's an open source so always preferred but Burp Suite Pro  will give you more options, its one of the best tool to have for pentesters so defo worth it.
