Effective vulnerability identification enhances security scans but AI-driven enhancements are needed
OWASP is only meant for two or three different types of scans. It is a tool which will scan the code for security for vulnerabilities We were able to convince the customers to really remove those rules when GitLab was able to show the results. Customers should be aware that GitLab is not just a…

Quotes from Members

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

Pros

"The HUD is a good feature that provides on-site testing and saves a lot of time."
"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."
"Automatic scanning is a valuable feature and very easy to use."
"The product helps users to scan and fix vulnerabilities in the pipeline."
"It's great that we can use it with Portswigger Burp."
"The application scanning feature is the most valuable feature."
"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."
"The scalability of this product is very good."
"It scans all the components developed within a web application."
"It is really accurate and the rate of false positives is very low."
"The most valuable feature is the reporting, which is compliant with international standards."
"Rapid7 AppSpider is good at managing different applications. It uses applets and generates reports to cover the PCA/GDPR compliance requirements."
"When it is set up properly, it can do scanning on web apps with multiple engines automatically."
"I would say that it is stable, as I am not aware of any major issues."
"The setup is usually straightforward."
"AppSpider's most valuable feature is reporting - everything is stored in the local database so it can be sent to other machines."
 

Cons

"The port scanner is a little too slow.​"
"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"The documentation is lacking and out-of-date, it really needs more love."
"There isn't too much information about it online."
"As security evolves, we would like DevOps built into it. As of now, Zap does not provide this."
"OWASP Zap needs to extend to mobile application testing."
"They stopped their support for a short period. They've recently started to come back again. In the early days, support was much better."
"The forced browse has been incorporated into the program and it is resource-intensive."
"The enterprise interface is too simple. It should be more customizable."
"AppSpider has some problems with the RAM needed while scanning."
"The solution is too slow. It could take a full day to scan. Competitors are much faster."
"It needs better integration with mobile applications."
"Integration could be better."
"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."
"AppSpider could improve in the area of integration. They need to add more integration opportunities."

"This solution is open source and free."
"The tool is open-source."
"The licensing cost depends on the number of users."
