Simplifies vulnerability discovery and has high quality support
There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Quotes from Members

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

Pros

"You can run it against multiple targets."
"Fuzzer and Java APIs help a lot with our custom needs."
"They offer free access to some other tools."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"The best feature is the Zap HUD (Heads Up Display) because the customers can use the website normally. If we scan websites with automatic scanning, and the website has a web application firewall, it's very difficult."
"One valuable feature of OWASP Zap is that it is simple to use."
"The most valuable feature of PortSwigger Burp Suite Professional is the advanced features, user-friendly interface, and integration with other tools."
"In my area of expertise, I feel like it has almost everything I could possibly require at this moment."
"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 most valuable feature of Burp Suite Professional is its ability to schedule tasks for scanning websites, which helps in performing regular checks of IP addresses."
"Some of the extensions, available using Burp Extender, are also very good and we have found issues by using them."
"The solution has a great user interface."
"One useful function is the ability to send requests to the repeater without making actual requests through the browser, allowing me to modify requests easily."
"It helps in API testing, where manual intervention was previously necessary for each payload."
 

Cons

"OWASP should work on reducing false positives by using AI and ML algorithms."
"The reporting feature could be more descriptive."
"Deployment is somewhat complicated."
"If there was an easier to understand exactly what has been checked and what has not been checked, it would make this solution better. We have to trust that it has checked all known vulnerabilities but it's a bit hard to see after the scanning."
"I would like to see a version of “repeater” within OWASP ZAP, a tool capable of sending from one to 1000 of the same requests, but with preselected modified fields, changing from a predetermined word ​list, or manually created."
"OWASP Zap needs to extend to mobile application testing."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"There could be an improvement in the API security testing. There is another tool called Postman and if we had a built-in portal similar to Postman which captures the API, we would be able to generate the API traffic. Right now we need a Postman tool and the Burp Suite for performing API tests. It would be a huge benefit to be able to do it in a single UI."
"The Burp Collaborator needs improvement. There also needs to be improved integration."
"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."
"PortSwigger Burp Suite Professional could improve the static code review."
"If your application uses multi-factor authentication, registration management cannot be automated."
"The number of false positives need to be reduced on the solution."
"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."
"You can have many false positives in Burp Suite. It depends on the scale of the penetration testing."
 

Pricing and Cost Advice

"It is highly recommended as it is an open source tool."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"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."
"It is open source, and we can scan freely."
"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 is an open-source solution and can be used free of charge."
"The solution’s pricing is high."
"The tool is open source."
"Burp Suite is affordable."
"It is a cheap solution, but it may not be cheaper than other solutions."
"This is a value for money product."
"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."
"There is no setup cost and the cost of licensing is affordable."

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.
