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

"It has improved my organization with faster security tests."

"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."

"The scalability of this product is very good."

"OWASP is quite matured in identifying the vulnerabilities."

"The stability of the solution is very good."

"OWASP is quite matured in identifying the vulnerabilities."

"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."

"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."

More OWASP Zap pros

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

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

"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."

"Some of the extensions, available using Burp Extender, are also very good and we have found issues by using them."

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

"It offers flexibility, macros, and features to reduce the effort required for authenticated sessions."

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

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

"Sometimes, we get some false positives."

"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."

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

"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."

"I would like to see a version of “repeater” within OWASP ZAP, a tool capable of sending from one to 1000 of the same requests, but with preselected modified fields, changing from a predetermined word list, or manually created."

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

More OWASP Zap cons

"The Iran market does not have after-sales support. PortSwigger Burp Suite Professional needs to provide after-sales support."

"The number of false positives need to be reduced on the solution."

"Scanning APIs using PortSwigger Burp Suite Professional takes a lot of time."

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

"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."

"The vendor must provide documentation on how to use the new API feature."

"The pricing of the solution is quite high."

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

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."

"The tool is open-source."

"The tool is open source."

"OWASP Zap is free to use."

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

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

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

"This solution is open source and free."

More OWASP Zap pricing and cost advice

"At $400 or $500 per license paid annually, it is a very cheap tool."

"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."

"For a country such as Sri Lanka, the pricing is not reasonable."

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

"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."

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

"The yearly cost is about $300."

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.
