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.

Pros

"You can run it against multiple targets."

"Simple and easy to learn and master."

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

"The solution is good at reporting the vulnerabilities of the application."

"It's great that we can use it with Portswigger Burp."

"We use the solution for security testing."

"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."

"The solution is quite helpful for session management and configuration."

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

"In my area of expertise, I feel like it has almost everything I could possibly require at this moment."

"The solution has a limited range of functions, which is good for small companies. This is because, in small companies, websites are less complex. They also have single services which makes the solution good enough for them. However, the most advantageous aspect of the solution is its affordable price."

"We use the solution for vulnerability assessment in respect of the application and the sites."

"The extension that it provides with the community version for the skills mapping is excellent."

More PortSwigger Burp Suite Professional pros

Cons

"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."

"OWASP Zap could benefit from a noise cancellation feature like that of Burp Suite Professional, where AI helps reduce certain non-critical findings."

"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."

"The port scanner is a little too slow."

"Reporting format has no output, is cluttered and very long."

"OWASP Zap needs to extend to mobile application testing."

"The reporting feature could be more descriptive."

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

More OWASP Zap cons

"The Burp Collaborator needs improvement. There also needs to be improved integration."

"The use of system memory is an area that can be improved because it uses a lot."

"It would be beneficial to have privileged access management as a part of Burp Suite Professional."

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

"The biggest drawback is reporting. It's not so good. I can download them, but they're not so informative."

"There needs to be better documentation provided. Currently, we need to buy books, or we need to review online some use cases from other professionals who have been using the solution to find out their experience. It is not easy to find out how to properly do a security assessment."

"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."

"Sometimes the solution can run a little slow."

More PortSwigger Burp Suite Professional cons

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.
