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.

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

"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"You can run it against multiple targets."
"Simple to use, good user interface."
"It updates repositories and libraries quickly."
"The product has improved our application security engagement, helps with our in-house review so we sometimes don't need an external third-party tester, and once we get it from OWASP Zap, we have an idea of the inherent vulnerabilities in the application, which is a plus to save cost and improve our application accuracy practice."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"Fuzzer and Java APIs help a lot with our custom needs."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"Currently, we're trying to import the solution to implement it to other applications for our website."
"Unearthing these issues really helps me build confidence and relationships with clients on two counts."
"This is by far the best application assessment tool I have used."
"PortSwigger Burp Suite Professional is superior in quite a few options."
"This is one of the best tools that I'm using; I found this one much better."
"The most valuable features are Burp Intruder and Burp Scanner."
"I found the best value, features and documentation in Burp."
"I have found this solution has more plugins than other competitors which is a benefit."
 

Cons

"OWASP Zap needs to extend to mobile application testing."
"We get too many false positives and that should definitely be improved."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"The port scanner is a little too slow.​"
"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."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"Lacks resources where users can internally access a learning module from the tool."
"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
"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."
"The solution is not easy to set it up. You need a lot of knowledge."
"In the Professional version, we cannot link it with the CI/CD process."
"Sometimes the solution can run a little slow."
"Even though I started working with PortSwigger Burp Suite Professional, I think I may have run the Scanner once, but I prefer to run ZAP because I'm more used to it and I think it checks many more vulnerabilities."
"There should be a heads up display like the one available in OWASP Zap."
"The Auto Scanning features should be updated more frequently and should include the latest attack vectors."
 

Pricing and Cost Advice

"The solution’s pricing is high."
"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."
"The tool is open source."
"This app is completely free and open source. So there is no question about any pricing."
"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."
"This is an open-source solution and can be used free of charge."
"The tool is open-source."
"It is open source, and we can scan freely."
"The solution is reasonably priced."
"This solution requires a license. It is expensive but you receive a lot of functionality for the price."
"We have one license. The price is very nominal."
"There are different licenses available that include a free version."
"There is no setup cost and the cost of licensing is affordable."
"Our licensing cost is approximately $400 USD per year."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"This is a value for money product."

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.
