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

"OWASP is definitely in the top three as a tool that we would probably recommend to our team, as a frequent users' tool, however, I don't believe we have any kind of a formal relationship with the company."
"The ZAP scan and code crawler are valuable features."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"Simple to use, good user interface."
"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications."
"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 scalable."
"The solution is quite helpful for session management and configuration."
"Their flagship feature would be the active scanner, which carries out an automated look up of any web vulnerabilities reflecting over to one of the main compliance standards, like OWASP, and provides an accurate security audit for their web applications."
"I find the attack model quite amazing, where I can write my scripts and load my scripts as well, which helps quite a bit. All the active scanning that it can do is also quite a lot helpful. It speeds up our vulnerability assessment and penetration testing. Right now, I am enjoying its in-browser, which also helps quite a bit. I'm always confused about setting up some proxy, but it really is the big solution we all want."
"If you compare it to more expensive tools like WebInspect or IBM AppScan, you'll realize that, at a very low cost, Burp Suite can provide good results."
"The solution has a pretty simple setup."
"You can scan any number of applications and it updates its database."
"The most valuable feature is the application security. It also has a reasonable price."
"This solution has helped our company in many ways."
 

Cons

"For scalability, I would rate OWASP Zap between four to five out of ten."
"There's very little documentation that comes with OWASP Zap."
"The forced browse has been incorporated into the program and it is resource-intensive."
"Deployment is somewhat complicated."
"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."
"I'd also like to see an improvement in test reports because we get too many false positives."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"There isn't too much information about it online."
"One area for improvement is the integrated browser, Chromium. Single Sign-On (SSO) methods like Microsoft authentication login sometimes fail and show errors. As a workaround, I have to use a different browser, such as Firefox, to log in and make Burp work."
"The one feature that I would like to see in Burp is active scanning of REST based web services."
"The Auto Scanning features should be updated more frequently and should include the latest attack vectors."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"There is not much automation in the tool."
"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."
"You can have many false positives in Burp Suite. It depends on the scale of the penetration testing."
"I would like to see a more optimized solution, as it currently uses a lot of CPU power and memory."
 

Pricing and Cost Advice

"It's free. It's good for us because we don't know what the extent of our use will be yet. It's good to start with something free and easy to use."
"We have used the freeware version. I believe Zap only has freeware."
"This solution is open source and free."
"This app is completely free and open source. So there is no question about any pricing."
"It is open source, and we can scan freely."
"The solution’s pricing is high."
"The tool is open-source."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"The pricing of the solution is cost-effective and is best suited for small and medium-sized businesses."
"It's a lower priced tool that we can rely on with good standard mechanisms."
"This solution requires a license. It is expensive but you receive a lot of functionality for the price."
"PortSwigger is reasonably-priced. It's fair."
"We have one license. The price is very nominal."
"There is no setup cost and the cost of licensing is affordable."
"They should reduce the license cost a little bit. It is $400 per user, and it would be better if they could reduce the licensing fee."
"We are using the community version, which is free."

OWASP Zap has web application scanning available with basic security vulnerabilities while Burp Suite Pro has it available with quality security vulnerabilities. Both are very comparable in terms of intercepting features, fuzzing capabilities, and encoder and decoders. Both OWASP Zap and PortSwigger Burp Suite Pro have a spide...

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.
