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

"The solution is scalable."
"It can be used effectively for internal auditing."
"Simple and easy to learn and master."
"Automatic updates and pull request analysis."
"The solution has tightened our security and that of our clients who depend on it."
"The ZAP scan and code crawler are valuable features."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"OWASP is quite matured in identifying the vulnerabilities."
"The most valuable feature is the reporting, which is compliant with international standards."
"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."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
"One of the most valuable features of AppSpider is its broad range of authentication identification, which is a key reason for its utilization."
"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."
"It scans all the components developed within a web application."
"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."
"The initial deployment is very straightforward and simple. The product is stable if configured properly."
 

Cons

"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."
"For scalability, I would rate OWASP Zap between four to five out of ten."
"ZAP's integration with cloud-based CICD pipelines could be better. The scan should run through the entire pipeline."
"There isn't too much information about it online."
"It doesn't run on absolutely every operating system."
"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 solution is somewhat unreliable because after we get the finding, we have to manually verify each of its findings to see whether it's a false positive or a true finding, and it takes time."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"There are some glitches with stability, and it is an area for improvement."
"The tech support is responsive but issues remain unresolved."
"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."
"For Japanese customers, localization is needed. The product should offer a GUI in Japanese and provide Japanese reports for end-users."
"This price of this solution is a little bit expensive."
"Integration could be better. For example, while doing the scanning, using the recording username and passwords, there are issues."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."
 

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."
"The tool is open source."
"This is an open-source solution and can be used free of charge."
"The tool is open-source."
"It is open source, and we can scan freely."
"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."
"This solution is open source and free."
"OWASP Zap is free to use."
"AppSpider is closed-source software and you need to acquire a license in order to use it."
"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."
"The price is pretty fair."
"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."
