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 ZAP scan and code crawler are valuable features."
"The most valuable feature is the spidering because, being a security person, it is very important for me to know each and every section of that application, so we cannot afford to miss any single web page or any single link on a particular website."
"The stability of the solution is very good."
"The valuable features are that it's very simple to use and the user interface is very good, particularly for beginners so they can start the application easily."
"The community support that ZAP provides me, as an open source, provides me flexibility and is convenient to use."
"This is a very mature tool; it is capable of facilitating the work of many security experts, and I highly recommend it for beginners and advanced users when some other tools fail to catch traffic."
"If you're a company and you've got your own websites, internally and externally, it's great."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"PortSwigger Burp Suite Professional is superior in quite a few options."
"BurpSuite helps us to identify and fix silly mistakes that are sometimes introduced by our developers in their coding."
"Some of the extensions, available using Burp Extender, are also very good and we have found issues by using them."
"It offers flexibility, macros, and features to reduce the effort required for authenticated sessions."
"This is one of the best tools that I'm using; I found this one much better."
"It was easy to learn."
"With the Extender Tab, if you know how to code then you can create a plugin and add it to Burp."
"I find the attack model quite amazing, where I can write my scripts and load my scripts as well, which helps quite a bit."
 

Cons

"We have had stability issues a few times."
"The product should allow users to customize the report based on their needs."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."
"Too many false positives; test reports could be improved."
"The forced browse has been incorporated into the program and it is resource-intensive."
"When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking."
"It doesn't run on absolutely every operating system."
"Scanning APIs using PortSwigger Burp Suite Professional takes a lot of time."
"I would like to see the return of the spider mechanism instead of the crawling feature. Burp Suite's earlier version 1.7 had an excellent spider option, and it would be beneficial if Burp incorporated those features into the current version. The crawling techniques used in the current version are not as efficient as those used in earlier versions."
"The one feature that I would like to see in Burp is active scanning of REST based web services."
"If your application uses multi-factor authentication, registration management cannot be automated."
"Mitigating the issues and low confluence issues needs some improvement. Implementing demand with the ChatGPT under the web solution is an additional feature I would like to see in the next release."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"BurpSuite has some issues regarding authentication with OAT tokens that need to be improved."
"I need the solution to be more user-friendly. The solution needs to be user-friendly."
 

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."
"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."
"We have used the freeware version. I believe Zap only has freeware."
"This app is completely free and open source. So there is no question about any pricing."
"The tool is open source."
"The solution’s pricing is high."
"It is open source, and we can scan freely."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"There is no setup cost and the cost of licensing is affordable."
"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."
"PortSwigger Burp Suite Professional is an expensive solution."
"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."
"The solution is reasonably priced."
"The pricing of the solution is cost-effective and is best suited for small and medium-sized businesses."
"It is a cheap solution, but it may not be cheaper than other solutions."

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.
