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.

Useful vulnerability reporting data, flexible, and simple implementation

I have had some stability problems but it could be the Microsoft Windows operating system. I found that closing other applications helps with stability. It is helpful to have as much memory as possible, such as eight gigabytes. The more pages being processed the more resources you need. I rate the stability of Rapid7 AppSpider a nine out of ten.

Quotes from Members

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

Pros

"The community edition updates services regularly. They add new vulnerabilities into the scanning list."

"The most valuable feature is scanning the URL to drill down all the different sites."

"The solution is good at reporting the vulnerabilities of the application."

"One valuable feature of OWASP Zap is that it is simple to use."

"The product helps users to scan and fix vulnerabilities in the pipeline."

"The best feature is the Zap HUD (Heads Up Display) because the customers can use the website normally. If we scan websites with automatic scanning, and the website has a web application firewall, it's very difficult."

"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."

"The scalability of this product is very good."

More OWASP Zap pros

"The most valuable feature of Rapid7 AppSpider is the vulnerability reporting data. Additionally, the data is reported in a convenient way rather than seeing them as a PDF. We are able to generate all the reports exactly what we want in a flexible way."

"The setup is usually straightforward."

"When it is set up properly, it can do scanning on web apps with multiple engines automatically."

"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."

"The solution is highly stable, rated at ten out of ten."

"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."

"The entire solution is interactive and has a point-and-click user experience, which makes it easy to find items or drill down on information. You don't need specialized skills to use the product."

"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."

More Rapid7 AppSpider pros

Cons

"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."

"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."

"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."

"OWASP Zap needs to extend to mobile application testing."

"The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."

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

"The port scanner is a little too slow."

More OWASP Zap cons

"This price of this solution is a little bit expensive."

"There are some glitches with stability, and it is an area for improvement."

"The solution is too slow. It could take a full day to scan. Competitors are much faster."

"Support response times are slow and can be improved."

"The enterprise interface is too simple. It should be more customizable."

"It needs better integration with mobile applications."

"Implementing Rapid7 AppSpider requires scanning and self-identification mechanisms. You can add different types of authentication to each scan."

"AppSpider has some problems with the RAM needed while scanning."

More Rapid7 AppSpider cons

Pricing and Cost Advice

"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."

"It is highly recommended as it is an open source tool."

"This solution is open source and free."

"This is an open-source solution and can be used free of charge."

"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."

More OWASP Zap pricing and cost advice

"The price is pretty fair."

"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."

"AppSpider is closed-source software and you need to acquire a license in order to use it."

"The licensing cost depends on the number of users."

"It is expensive if you want to buy the Enterprise version that is able to scan multiple applications at once."
