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

"OWASP is quite matured in identifying the vulnerabilities."
"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."
"The application scanning feature is the most valuable feature."
"The solution is good at reporting the vulnerabilities of the application."
"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."
"Fuzzer and Java APIs help a lot with our custom needs."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"The HUD is a good feature that provides on-site testing and saves a lot of time."
"I personally love its capability to automatically and accurately detect vulnerabilities. So, I would say it is the Burp scanner that is THE most powerful, valuable, and an awesome feature."
"I have found the best features to be the performance and there are a lot of additional plugins available."
"It offers very good accuracy. You can trust the results."
"The extension that it provides with the community version for the skills mapping is excellent."
"The solution helped us discover vulnerabilities in our applications."
"PortSwigger Burp Suite Professional is one of the best user-friendly solutions for getting the proxy set up."
"The solution scans web applications and supports APIs, which are the main features I really like."
"I am impressed with the tool's detailed analysis for penetration testing. AppScan can give only visibility, but it can't do the PT part. But the PortSwigger Burp Application can do both, and it gives much more visibility on the PT rating."
 

Cons

"For scalability, I would rate OWASP Zap between four to five out of ten."
"The product reporting could be improved."
"I'd like to see a kind of feature where we can just track what our last vulnerability was and how it has improved or not. More reports that can have some kind of base-lining, I think that would be a good feature too. I'm not sure whether it can be achieved and implement but I think that would really help."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"It needs more robust reporting tools."
"It would be nice to have a solid SQL injection engine built into Zap."
"The port scanner is a little too slow.​"
"Integration is a big problem."
"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."
"The Initial setup is a bit complex."
"The price could be better. The rest is fine."
"BurpSuite has some issues regarding authentication with OAT tokens that need to be improved."
"As with most automated security tools, too many false positives."
"If we're running a huge number of scans regularly, it slows down the tool."
"The solution doesn't offer very good scalability."
 

Pricing and Cost Advice

"OWASP Zap is free to use."
"It is highly recommended as it is an open source tool."
"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."
"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'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."
"We have used the freeware version. I believe Zap only has freeware."
"The solution’s pricing is high."
"Our licensing cost is approximately $400 USD per year."
"They should reduce the license cost a little bit. It is $400 per user, and it would be better if they could reduce the licensing fee."
"It's a lower priced tool that we can rely on with good standard mechanisms."
"PortSwigger Burp Suite Professional is expensive compared to other tools."
"There is no setup cost and the cost of licensing is affordable."
"It is a cheap solution, but it may not be cheaper than other solutions."
"We have one license. The price is very nominal."
"At $400 or $500 per license paid annually, it is a very cheap tool."

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.
