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

"It scans while you navigate, then you can save the requests performed and work with them later."
"The scalability of this product is very good."
"If you're a company and you've got your own websites, internally and externally, it's great."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"We use the solution for security testing."
"This solution is providing us with value and as long as it continues to do so, we'll continue to use it."
"Burp has several good features; it's cheaper than other solutions and you can scan any number of applications and it updates its database."
"The product has a good learning hub."
"It offers very good accuracy. You can trust the results."
"Once I capture the proxy, I'm able to transfer across. All the requested information is there. I can send across the request to what we call a repeater, where I get to ready the payload that I send to the application. Put in malicious content and then see if it's responding to it."
"PortSwigger Burp Suite Professional is one of the best user-friendly solutions for getting the proxy set up."
"The most valuable features are Burp Intruder and Burp Scanner."
"The most valuable feature of PortSwigger Burp Suite Professional is the dashboard, which is very informative and lets you receive all the information you need in one place, as it is clear, well-defined, and organized so that anybody without any cybersecurity experience can use it."
"The intercepting feature is the most valuable."
 

Cons

"We get too many false positives and that should definitely be improved."
"Reporting format has no output, is cluttered and very long."
"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."
"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 solution is somewhat unreliable because after we get the finding, we have to manually verify each of its findings to see whether it's a false positive or a true finding, and it takes time."
"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."
"I would recommend this product to people although I think it is very difficult to deploy and we also have issues with maintenance."
"There isn't too much information about it online."
"The Burp Collaborator needs improvement. There also needs to be improved integration."
"The biggest drawback is reporting. It's not so good. I can download them, but they're not so informative."
"Even though I started working with PortSwigger Burp Suite Professional, I think I may have run the Scanner once, but I prefer to run ZAP because I'm more used to it and I think it checks many more vulnerabilities."
"Improvement should be done as per the requirements of customers."
"The one feature that I would like to see in Burp is active scanning of REST based web services. A lot of organizations are providing APIs to access their services to support different business models like SaaS. Scanning these APIs is still a challenge for many security product companies."
"The Initial setup is a bit complex."
"For a country such as Sri Lanka, the pricing is not reasonable."
"It's not so stable. Some of the security aspects aren't so stable."
 

Pricing and Cost Advice

"This is an open-source solution and can be used free of charge."
"The tool is open source."
"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."
"This solution is open source and free."
"It is highly recommended as it is an open source tool."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"The solution’s pricing is high."
"Burp Suite is affordable."
"PortSwigger is reasonably-priced. It's fair."
"It has a yearly license. I am satisfied with its price."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."
"Pricing is not very high. It was around $200."
"The platform's pricing is reasonable."
"I rate the pricing a four out of ten."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."

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.
