Effective vulnerability identification enhances security scans but AI-driven enhancements are needed
OWASP is only meant for two or three different types of scans. It is a tool which will scan the code for security for vulnerabilities We were able to convince the customers to really remove those rules when GitLab was able to show the results. Customers should be aware that GitLab is not just a…

AI-driven analyses improve efficiency and reliability
I find all the features of PortSwigger Burp Suite Professional most useful, particularly the AI enhancement for results and follow-up for retests. This feature helps me follow up on my results and perform retests step-by-step. The automation in AI verifies the findings, ensuring they are correct, and performs step-by-step testing. The Intruder tool enhances testing efficiency through intercepting information and analyzing it. It helps to analyze web applications and intercept the traffic.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Fuzzer and Java APIs help a lot with our custom needs."
"The API is exceptional."
"It has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"The HUD is a good feature that provides on-site testing and saves a lot of time."
"It can be used effectively for internal auditing."
"The community edition updates services regularly. They add new vulnerabilities into the scanning list."
"The scalability of this product is very good."
"The solution is good at reporting the vulnerabilities of the application."
"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."
"The solution is quite helpful for session management and configuration."
"It's good testing software."
"The technical support from PortSwigger is excellent, managing response time and quality efficiently without any issues."
"This tool is more accurate than the other solutions that we use, and reports fewer false positives."
"BurpSuite helps us to identify and fix silly mistakes that are sometimes introduced by our developers in their coding."
"In my area of expertise, I feel like it has almost everything I could possibly require at this moment."
"With the Extender Tab, if you know how to code then you can create a plugin and add it to Burp."
 

Cons

"The port scanner is a little too slow.​"
"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."
"Lacks resources where users can internally access a learning module from the tool."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"There isn't too much information about it online."
"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."
"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."
"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."
"I need the solution to be more user-friendly. The solution needs to be user-friendly."
"Sometimes the solution can run a little slow."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"The technical support team's response time is mostly delayed and should be improved."
"Currently, the scanning is only available in the full version of Burp, and not in the Community version."
"The solution’s pricing could be improved."
"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 could improve the static code review."
 

Pricing and Cost Advice

"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
"It is open source, and we can scan freely."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."
"We have used the freeware version. I believe Zap only has freeware."
"The solution’s pricing is high."
"This solution is open source and free."
"The tool is open source."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"The solution is reasonably priced."
"This is a value for money product."
"Pricing is not very high. It was around $200."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."

"There is no setup cost and the cost of licensing is affordable."

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.

Yes OWASP ZAP is a good option as it's an open source so always preferred but Burp Suite Pro  will give you more options, its one of the best tool to have for pentesters so defo worth it.
