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.

Quotes from Members

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

Pros

"Simple and easy to learn and master."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"The product discovers more vulnerabilities compared to other tools."
"The ZAP scan and code crawler are valuable features."
"The HUD, Heads Up Display, is a good feature; it provides on-site testing and saves a lot of time."
"The scalability of this product is very good."
"Simple to use, good user interface."
"The API is exceptional."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
"It does a scan that performs about 100 checks on web applications and produces a clear report on all of the vulnerabilities that are found."
"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"The solution is highly stable, rated at ten out of ten."
"What I like most about AppSpider is that it's easy to use and its automated scan gives me all the details I need to know when it comes to vulnerabilities and their solutions."
"Customer service has been quite good."
 

Cons

"The forced browse has been incorporated into the program and it is resource-intensive."
"It needs more robust reporting tools that can be in an editable form."
"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."
"The port scanner is a little too slow.​"
"It doesn't run on absolutely every operating system."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"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."
"We're currently moving away from OWASP to PortSwigger Burp Suite Professional; it's more user-friendly with a better interface."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"The performance of the solution could improve. When I compare the speed it is slower than others on the market. There are some tricks we use to help speed up the solution."
"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"The dashboard and interface are crucial and they need some improvement."
"It needs better integration with mobile applications."
"The product needs to be able to scale for large companies, like ours. We have millions of IP addresses that need to be scanned, and the scalability is not great."
"Support response times are slow and can be improved."
"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."
 

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'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."
"OWASP Zap is free to use."
"It is open source, and we can scan freely."
"We have used the freeware version. I believe Zap only has freeware."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
"The price is pretty fair."
"The licensing cost depends on the number of users."
"The price of Rapid7 AppSpider cost 9,000 annually but there is limited usage. Large companies are able to negotiate a better price or a better deal for the usage with the vendor."
