Executive SummaryUpdated on Feb 8, 2026

PortSwigger Burp Suite Professional and OWASP Zap are prominent competitors in web application security testing tools. Burp Suite often has the upper hand due to its extensive features and more integrated approach, while Zap stands out for its cost-free accessibility, benefiting budget-conscious users.

Features: Burp Suite Professional offers a comprehensive suite including Proxy, Repeater, and Intruder, with robust auto-scanning and vulnerability detection. It supports customizable payloads and extensions through an active community. OWASP Zap provides features like automated scanning, a unique Heads Up Display, and manual testing capabilities, thriving as an open-source platform that benefits from extensive community-backed enhancements.

Room for Improvement: Burp Suite users seek better integration options, improved reporting functionalities, and reduced false positives, particularly in REST API testing. OWASP Zap can enhance reporting templates and provide regular feature updates, along with improved documentation and integration features to bridge the gap with Burp's functionality.

Ease of Deployment and Customer Service: Both tools primarily deploy on-premises, with Burp Suite also available in private and hybrid clouds. Burp's direct technical support is praised for its responsiveness, while Zap's community forums serve as a primary resource due to its open-source nature.

Pricing and ROI: Burp Suite Professional is recognized for its high-value features, though its licenses might be costly for smaller businesses, yet offering substantial ROI through its reliability and comprehensive capabilities. OWASP Zap, being entirely free and open-source, is invaluable for budget-restricted organizations, despite lacking some premium features found in Burp Suite.

Open source testing tool empowers manual activities and has room to improve integration and reporting features
The improvement that has to be done for APIs focuses on manual activities where the feature exists, but it is not at the same level as what Burp Suite does with intercepting and tools such as Postman, so it needs improvement. There are limitations with authentication levels, particularly with form-based and cookie-based authentication. However, overall, we are satisfied with OWASP Zap as there are no major issues, and improving the scan engine could be beneficial. 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.

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."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"It's great that we can use it with Portswigger Burp."
"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool and at the same time give a comprehensive report with great confidence to the client for helping them in their go-live decision."
"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."
"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."
"This solution is providing us with value and as long as it continues to do so, we'll continue to use it."
"The scalability of this product is very good."
More OWASP Zap pros
"This solution has helped our company in many ways."
"PortSwigger Burp Suite does not hamper the node of the server, and it does not shut down the server if it is running."
"This tool is more accurate than the other solutions that we use, and reports fewer false positives."
"PortSwigger Burp Suite Professional has improved the organization by providing the security standards of the applications across the organization."
"We found PortSwigger to be the best match for our business."
"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."
"Burp is the best web application penetration testing tool that I have ever used."
"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."
More PortSwigger Burp Suite Professional pros
 

Cons

"There's very little documentation that comes with OWASP Zap."
"It needs more robust reporting tools that can be in an editable form."
"The forced browse has been incorporated into the program and it is resource-intensive."
"While the solution can scale to a certain extent, it cannot scale a lot."
"It would be nice to have a solid SQL injection engine built into Zap."
"I prefer Burp Suite to SWASP Zap because of the extensive coverage it offers."
"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."
"The port scanner is a little too slow."
More OWASP Zap cons
"I would like to see a more optimized solution, as it currently uses a lot of CPU power and memory."
"The initial setup is a bit complex."
"I am from Brazil. The currency exchange rate from a dollar to a Brazilian Real is quite steep. It is almost six to one. It would be good if it can be sold in the local currency, and its price is cheaper for us."
"Sometimes the solution can run a little slow."
"The scanner and crawler need to be improved."
"One thing that is not up to the mark in PortSwigger is web application testing."
"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."
"Sometimes the solution can run a little slow."

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.
