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

"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."

"The scalability of this product is very good."

"The solution has tightened our security."

"OWASP is quite matured in identifying the vulnerabilities."

"We use the solution for security testing."

"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."

"It scans while you navigate, then you can save the requests performed and work with them later."

"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."

More OWASP Zap pros

"The solution has a pretty simple setup."

"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."

"With the Extender Tab, if you know how to code then you can create a plugin and add it to Burp."

"It offers very good accuracy. You can trust the results."

"It's good testing software."

"It was easy to learn."

"The most valuable feature is Burp Collaborator."

"It is useful for scanning and tracing activities."

More PortSwigger Burp Suite Professional pros

Cons

"The solution is unable to customize reports."

"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."

"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 beneficial to enhance the algorithm to provide better summaries of automatic scanning results."

"OWASP should work on reducing false positives by using AI and ML algorithms."

"It needs more robust reporting tools."

"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."

"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."

More OWASP Zap cons

"The technical support team's response time is mostly delayed and should be improved."

"You can have many false positives in Burp Suite. It depends on the scale of the penetration testing."

"The scanner and crawler need to be improved."

"It should provide a better way to integrate with Jenkins so that DAST (dynamic application security testing) can be automated."

"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."

"The solution’s pricing could be improved."

"It would be good if the solution could give us more details about what exactly is defective."

More PortSwigger Burp Suite Professional cons

Pricing and Cost Advice

"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."

"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."

"It is open source, and we can scan freely."

"The tool is open source."

"This solution is open source and free."

"This app is completely free and open source. So there is no question about any pricing."

More OWASP Zap pricing and cost advice

"We are using the community version, which is free."

"We pay a yearly licensing fee for the solution, which is neither cheap nor expensive."

"The yearly cost is about $300."

"This is a value for money product."

"We have one license. The price is very nominal."

"PortSwigger Burp Suite Professional is an expensive solution."

"This solution requires a license. It is expensive but you receive a lot of functionality for the price."

"It is expensive for us in Brazil because the currency exchange rate from a dollar to a Brazilian Real is quite steep."

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.
