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.
Anuradha.Kapoor Kapoor - PeerSpot reviewer
Offers efficient scanning of entire websites but presence of false positive bugs, leading to time-consuming efforts in distinguishing real bugs from false alarms
We have found that so many times, false positive bugs are there, and then we spend a lot of time basically separating them from real bugs. So that's the reason we are looking for some other tool. So we were in discussion with Acunetix. Therefore, the false positive rate is, like, something that we would like to improve. What we are looking for is if this false positive rate goes down because we were OWASP Zap tool users, which was free anyway. But 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. So then we thought, okay, why not we go with the tool? Even if it is not very expensive. But still, every year, we have to renew the license. And we got this tool. Again, we found that in this tool also, even if it is less, there are still a lot of false positive bugs out there. So we again have to spend so much time. So we hired a security tester, who was basically using Acunetix in his previous company for almost three years, and then you said that in that scanning is very slow. The scanning is also slow. Like, sometimes the site scan takes eight hours, six to eight hours. Yeah. And whereas in Acunetix, it took three to four hours. And plus, there are no false positives. I'm not saying none but there's very little. But here, the rate sometimes is very high. These are the two features I think we would like to improve further.

Quotes from Members

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

Pros

"They offer free access to some other tools."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"OWASP is quite matured in identifying the vulnerabilities."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"The product discovers more vulnerabilities compared to other tools."
"It updates repositories and libraries quickly."
"It can be used effectively for internal auditing."
"The HUD is a good feature that provides on-site testing and saves a lot of time."
""The product is very good just the way it is; It has everything already well established and functions great. I can't see any way for this current version to be improved.""
"The automated scan is what I find most useful because a lot of customers will need it. Not every domain will be looking for complete security, they just need a stamp on the security key. For these kinds of customers, the scan works really well."
"The suite testing models are very good. It's very secure."
"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 solution scans web applications and supports APIs, which are the main features I really like."
"It offers flexibility, macros, and features to reduce the effort required for authenticated sessions."
"It's good testing software."
"It helps in API testing, where manual intervention was previously necessary for each payload."
 

Cons

"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"There are too many false positives."
"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."
"The port scanner is a little too slow.​"
"It would be nice to have a solid SQL injection engine built into Zap."
"OWASP Zap needs to extend to mobile application testing."
"It needs more robust reporting tools."
"Sometimes the solution can run a little slow."
"Improvement should be done as per the requirements of customers."
"If we're running a huge number of scans regularly, it slows down the tool."
"The price could be better. The rest is fine."
"Scanning APIs using PortSwigger Burp Suite Professional takes a lot of time."
"It would be beneficial to have privileged access management as a part of Burp Suite Professional."
"It should provide a better way to integrate with Jenkins so that DAST (dynamic application security testing) can be automated."
"The technical support team's response time is mostly delayed and should be improved."
 

Pricing and Cost Advice

"We have used the freeware version. I believe Zap only has freeware."
"OWASP Zap is free to use."
"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."
"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."
"It is highly recommended as it is an open source tool."
"This is an open-source solution and can be used free of charge."
"The tool is open source."
"The solution used to be expensive. However, they have reduced the price to approximately $400.00 which is reasonable."
"There are different licenses available that include a free version."
"For a country such as Sri Lanka, the pricing is not reasonable."
"Pricing is not very high. It was around $200."
"This solution requires a license. It is expensive but you receive a lot of functionality for the price."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"Burp Suite is affordable."
"It's a lower priced tool that we can rely on with good standard mechanisms."

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.
