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.

"The HUD is a good feature that provides on-site testing and saves a lot of time."

"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."

"The product helps users to scan and fix vulnerabilities in the pipeline."

More OWASP Zap pros

"I rate PortSwigger Burp Suite Professional ten points out of ten."

"PortSwigger Burp Suite Professional is superior in quite a few options."

"PortSwigger Burp Suite Professional has an intercept tab that helps us to scan our APIs, set the response, and request errors."

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

"The Spider is the most useful feature. It helps to analyze the entire web application, and it finds all the passes and offers an automated identification of security issues."

"The tool provides complimentary services. It allows you to add a lot of extensions, and you can get extensions quite often. It is quite a flexible application."

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

More PortSwigger Burp Suite Professional pros

Cons

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

"It doesn't run on absolutely every operating system."

"The reporting feature could be more descriptive."

"For scalability, I would rate OWASP Zap between four to five out of ten."

"The documentation is lacking and out-of-date, it really needs more love."

"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."

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

"There are too many false positives."

More OWASP Zap cons

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

"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."

"I need the solution to be more user-friendly. The solution needs to be user-friendly."

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

"The biggest improvement that I would like to see from PortSwigger that today many people see as an issue in their testing. There might be a feature which might be desired."

"I would like to see a more optimized solution, as it currently uses a lot of CPU power and memory."

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

"If we're running a huge number of scans regularly, it slows down the tool."

More PortSwigger Burp Suite Professional cons

"The tool is open-source."

"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."

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.
