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

"The product discovers more vulnerabilities compared to other tools."
"OWASP is quite matured in identifying the vulnerabilities."
"One valuable feature of OWASP Zap is that it is simple to use."
"The interface is easy to use."
"The scalability of this product is very good."
"OWASP is quite matured in identifying the vulnerabilities."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."
"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."
"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."
"We use the solution for vulnerability assessment in respect of the application and the sites."
"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."
"The solution has a great user interface."
"The extension that it provides with the community version for the skills mapping is excellent."
"I have found the best features to be the performance and there are a lot of additional plugins available."
"There is no other tool like it. I like the intuitiveness and the plugins that are available."
 

Cons

"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"OWASP Zap needs to extend to mobile application testing."
"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."
"The forced browse has been incorporated into the program and it is resource-intensive."
"Sometimes, we get some false positives."
"There are too many false positives."
"It needs more robust reporting tools."
"The price could be better. The rest is fine."
"If your application uses multi-factor authentication, registration management cannot be automated."
"The solution lacks sufficient stability."
"It would be beneficial to have privileged access management as a part of Burp Suite Professional."
"The technical support team's response time is mostly delayed and should be improved."
"The solution is not easy to set it up. You need a lot of knowledge."
"Improvement should be done as per the requirements of customers."
"A lot of our interns find it difficult to get used to PortSwigger Burp's environment."
 

Pricing and Cost Advice

"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."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"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."
"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 app is completely free and open source. So there is no question about any pricing."
"The solution’s pricing is high."
"Licensing costs are about $450/year for one use. For larger organizations, they're able to test against multiple applications while simultaneously others might have multiple versions of applications which needs to be tested which is why we have the enterprise edition."
"For a country such as Sri Lanka, the pricing is not reasonable."
"There are different licenses available that include a free version."
"PortSwigger Burp Suite Professional is an expensive solution."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."
"The yearly cost is about $300."

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.
