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

"OWASP Zap is a good tool, one of my favorites for a long time, and I would recommend it."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"It scans while you navigate, then you can save the requests performed and work with them later."
"Fuzzer and Java APIs help a lot with our custom needs."
"The most valuable feature is scanning the URL to drill down all the different sites."
"This solution has improved my organization because it has made us feel safer doing frequent deployments for web applications. If we have something really big, we might get some professional company in to help us but if we're releasing small products, we will check it ourselves with Zap. It makes it easier and safer."
"You can run it against multiple targets."
"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 solution scans web applications and supports APIs, which are the main features I really like."
"The most valuable feature of PortSwigger Burp Suite Professional is the Burp Intruder tool."
"PortSwigger Burp Suite Professional is one of the best user-friendly solutions for getting the proxy set up."
"It helps in API testing, where manual intervention was previously necessary for each payload."
"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."
"PortSwigger Burp Suite does not hamper the node of the server, and it does not shut down the server if it is running."
"PortSwigger Burp Suite Professional is superior in quite a few options."
""The product is very good just the way it is; It has everything already well established and functions great. I can't see any way for this current version to be improved.""
 

Cons

"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"Lacks resources where users can internally access a learning module from the tool."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"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 technical support team must be proactive."
"The documentation is lacking and out-of-date, it really needs more love."
"PortSwigger Burp Suite Professional can improve by having more features in the free version for beginners to try."
"The solution’s pricing could be improved."
"Scanning needs to be improved in enterprise and professional versions."
"The one feature that I would like to see in Burp is active scanning of REST based web services. A lot of organizations are providing APIs to access their services to support different business models like SaaS. Scanning these APIs is still a challenge for many security product companies."
"The solution lacks sufficient stability."
"It would be beneficial to have privileged access management as a part of Burp Suite Professional."
"The vendor must provide documentation on how to use the new API feature."
"The price could be better. The rest is fine."
 

Pricing and Cost Advice

"OWASP Zap is free to use."
"This app is completely free and open source. So there is no question about any pricing."
"The solution’s pricing is high."
"It is open source, and we can scan freely."
"This solution is open source and free."

"For a country such as Sri Lanka, the pricing is not reasonable."
"The solution is reasonably priced."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"The solution used to be expensive. However, they have reduced the price to approximately $400.00 which is reasonable."
"It has a yearly license. I am satisfied with its price."
"The price for the solution is expensive and could be cheaper. We pay an annual license and our team has several of them."
"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."

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.
