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

"They offer free access to some other tools."

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

"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."

"The most valuable feature is scanning the URL to drill down all the different sites."

"Stability-wise, I rate the solution a nine out of ten. I think it's stable enough. I don't see any crashes within the application, so its stability is high."

"Simple and easy to learn and master."

"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."

More OWASP Zap pros

"The solution helped us discover vulnerabilities in our applications."

"The initial setup is simple."

"The feature that we have found most valuable is that it comes with pre-set configurations. They have a set of predefined options where you can pick one and start scanning. We also have the option of creating our own configurations, like how often do the applications need to be scanned."

"There is no other tool like it. I like the intuitiveness and the plugins that are available."

"I have found this solution has more plugins than other competitors which is a benefit. You are able to attach different plugins to the security scan to add features. For example, you can check to see if there are any payment systems that exist on a server, or username and password brute force analysis."

"It's good testing software."

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

"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."

More PortSwigger Burp Suite Professional pros

Cons

"It needs more robust reporting tools."

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

"It would be nice to have a solid SQL injection engine built into Zap."

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

"The reporting feature could be more descriptive."

"The documentation is lacking and out-of-date, it really needs more love."

"There's very little documentation that comes with OWASP Zap."

"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

"There is a lot to this product, and it would be good if when you purchase the tool, they can provide us with a more extensive user manual."

"In the Professional version, we cannot link it with the CI/CD process."

"There is not much automation in the tool."

"BurpSuite has some issues regarding authentication with OAT tokens that need to be improved."

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

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

"Even though I started working with PortSwigger Burp Suite Professional, I think I may have run the Scanner once, but I prefer to run ZAP because I'm more used to it and I think it checks many more vulnerabilities."

"Integration is a big problem."

More PortSwigger Burp Suite Professional cons

Pricing and Cost Advice

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

"It is highly recommended as it is an open source tool."

"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."

"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 solution is open source and free."

"We have used the freeware version. I believe Zap only has freeware."

More OWASP Zap pricing and cost advice

"It's a lower priced tool that we can rely on with good standard mechanisms."

"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."

"The solution used to be expensive. However, they have reduced the price to approximately $400.00 which is reasonable."

"This is a value for money product."

"PortSwigger Burp Suite Professional is expensive compared to other tools."

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.
