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.

This alignment with the present severity score and CVSS score could be improved.

"OWASP is quite matured in identifying the vulnerabilities."

More OWASP Zap pros

"The most valuable feature is the ability to write our custom rules."

Cons

"There are too many false positives."

"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."

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

"The documentation needs to be improved because I had to learn everything from watching YouTube videos."

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

"The documentation is lacking and out-of-date, it really needs more love."

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."

More OWASP Zap cons

"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."

Pricing and Cost Advice

"The tool is open-source."

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

"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."

"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."

"The tool is open source."

"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
