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 API is exceptional."

"The product has improved our application security engagement, helps with our in-house review so we sometimes don't need an external third-party tester, and once we get it from OWASP Zap, we have an idea of the inherent vulnerabilities in the application, which is a plus to save cost and improve our application accuracy practice."

"Automatic scanning is a valuable feature and very easy to use."

"The scalability of this product is very good."

"OWASP is quite matured in identifying the vulnerabilities."

"The solution enables a person to add the certificate and check the queries, to see if there are any that are undefined, so a person can have a list of the types of queries and can trace them."

"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."

"The ZAP scan and code crawler are valuable features."

More OWASP Zap pros

"The most valuable feature is Burp Collaborator."

"It's good testing software."

"Burp Suite gives you a very good automated scanning tool, which gives you around sixty to seventy percent security coverage without having to use a security resource."

"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."

"I have found the best features to be the performance and there are a lot of additional plugins available."

"Currently, we're trying to import the solution to implement it to other applications for our website."

"This tool is more accurate than the other solutions that we use, and reports fewer false positives."

"It was easy to learn."

More PortSwigger Burp Suite Professional pros

Cons

"The forced browse has been incorporated into the program and it is resource-intensive."

"The reporting feature could be more descriptive."

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."

"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."

"It needs more robust reporting tools."

"We have had stability issues a few times."

"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."

"Deployment is somewhat complicated."

More OWASP Zap cons

"The one feature that I would like to see in Burp is active scanning of REST based web services."

"The price could be better. The rest is fine."

"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."

"A lot of our interns find it difficult to get used to PortSwigger Burp's environment."

"The solution lacks sufficient stability."

"Scanning needs to be improved in enterprise and professional versions."

"The pricing of the solution is quite high."

"We wish that the Spider feature would appear in the same shape that it does in previous versions."

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."

"This is an open-source solution and can be used free of charge."

"The tool is open-source."

"The tool is open source."

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."

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

"The solution’s pricing is high."

"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."

More OWASP Zap pricing and cost advice

"The pricing of the solution is cost-effective and is best suited for small and medium-sized businesses."

"The solution is reasonably priced."

"PortSwigger Burp Suite Professional is an expensive solution."

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

"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."

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

"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.
