Featured Reviews

Amit Beniwal - PeerSpot reviewer
Simplifies vulnerability discovery and has high quality support
There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.
Jos Badimo - PeerSpot reviewer
Test assurance improves compliance and products with good performance
The user interface could be improved to facilitate easier navigation. The most significant issue I encounter with the solution is the user interface. It would be beneficial if I could remain on one screen most of the time. Even if the system navigates me to another screen, it should effectively return me to the main screen.

Quotes from Members

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

Pros

"The most valuable feature is scanning the URL to drill down all the different sites."
"The solution has tightened our security."
"​It has improved my organization with faster security tests.​"
"Automatic scanning is a valuable feature and very easy to use."
"It can be used effectively for internal auditing."
"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 has evolved over the years and recently in the last year they have added, HUD (Heads Up Display)."
"OWASP is quite matured in identifying the vulnerabilities."
"The testing compliance feature is particularly impressive."
"The feature I find most valuable is the traffic generator."
"Our customers use it to check for unauthorized file transfer."
"CyberFlood's best features are its user-friendliness and scheduling function."
"CyberFlood is flexible."
"The testing compliance feature is particularly impressive."
 

Cons

"Lacks resources where users can internally access a learning module from the tool."
"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."
"The product should allow users to customize the report based on their needs."
"OWASP should work on reducing false positives by using AI and ML algorithms. They should expand their capabilities for broader coverage of business logic flaws and complex issues."
"OWASP should work on reducing false positives by using AI and ML algorithms."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"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."
"Sometimes, when you configure parameters the hardware can't run, it will get stuck at those points without telling you what happened. It would be helpful if the error reporting provided more details about why the test setting is not running. It would be nice if there were a space in the hardware module for you to add some external hardware for more rigorous testing."
"I would also like to see updates on a more frequent schedule."
"The initial setup is not straightforward and can be quite challenging."
"The solution needs more ports, more speed, and more gigabytes."
"The user interface could be improved to facilitate easier navigation."
"CyberFlood's accessibility and support for multiple browsers could be better."
 

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."
"This is an open-source solution and can be used free of charge."
"The solution’s pricing is high."
"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."
"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."
"CyberFlood is reasonably priced."
