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

"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"The scalability of this product is very good."
"They offer free access to some other tools."
"The solution is very easy to use, the initial setup is straightforward, it is free due to the fact that it is open-source, the stability is very good, and the product has a strong community surrounding it to help with issues and troubleshooting."
"This solution is providing us with value and as long as it continues to do so, we'll continue to use it."
"OWASP is the best."
"The interface is easy to use."
"The API is exceptional."
"The active scanner, which does an automated search of any web vulnerabilities."
"The most valuable features are Burp Intruder and Burp Scanner."
"We use the solution for vulnerability assessment in respect of the application and the sites."
"This is one of the best tools that I'm using; I found this one much better."
"I have found this solution has more plugins than other competitors which is a benefit."
"The solution has a limited range of functions, which is good for small companies. This is because, in small companies, websites are less complex. They also have single services which makes the solution good enough for them. However, the most advantageous aspect of the solution is its affordable price."
"We are mostly using it for scanning the entire website. So, we basically create a script with the entire website and then run it for different injections."
"Burp Suite gives you a very good automated scanning tool, which gives you around sixty to seventy percent security coverage without having to use a security resource."
 

Cons

"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."
"The solution is unable to customize reports."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"It would be nice to have a solid SQL injection engine built into Zap."
"The documentation is lacking and out-of-date, it really needs more love."
"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."
"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."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"The professional edition of Burp Suite provides some automated pen-testing scripts to detect application vulnerabilities, like SQL injection, XSS, etc. However, this component is not extremely useful."
"It would be good if the solution could give us more details about what exactly is defective."
"Sometimes the solution can run a little slow."
"The technical support team's response time is mostly delayed and should be improved."
"The interface for the automatic scan can be improved because it is easy for technical users, but the business users have trouble with it."
"Scanning APIs using PortSwigger Burp Suite Professional takes a lot of time."
"The Auto Scanning features should be updated more frequently and should include the latest attack vectors."
"PortSwigger Burp Suite Professional could improve the static code review."
 

Pricing and Cost Advice

"This solution is open source and free."
"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 solution’s pricing is high."
"The tool is open-source."
"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 highly recommended as it is an open source tool."
"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."
"The platform's pricing is reasonable."
"This is a value for money product."
"We are using the community version, which is free."
"There are different licenses available that include a free version."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"We have one license. The price is very nominal."
"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."

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.
