Has supported early vulnerability detection but requires tuning to reduce false positives and scanning delays

When assessing the accuracy and efficiency of Checkmarx SAST scanning capabilities, they are currently recommending that doing the full scan is the main, correct way of scanning the repositories. However, based on the repository size we have, it sometimes takes more than 10 minutes for larger repositories, which is a downside. The accuracy of the results depends on various factors, as some of the test folders tend to give us false positives, which makes a huge impact on the vulnerabilities. Those are the major things that we have to fine-tune from our end. I would rate Checkmarx SAST around a seven, as it does have some false positives we have to work with, which are the major concerning things. The number of false positives is significant because we cannot implement policies because of this.

Quotes from Members

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

"The most important competitive advantage and benefit is the ability to identify vulnerabilities in the source code immediately without needing to complete the coding."

"The setup is usually straightforward."

"I like the ability the product has to detect vulnerabilities quickly, when it has been released in our environment, then displaying them to us."

"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."

Cons

"The on-premises version is more expensive compared to the cloud version."

"We had some issues where Checkmarx did not recognize a vulnerability."

"We had some issues where Checkmarx did not recognize a vulnerability. We had to talk with the vendor, and they had to include an improvement in the tool to resolve this issue."

"I believe that nothing in particular could be improved about Checkmarx SAST, only the turnaround time and the fact that technical account managers keep moving around, which leads to some lag in communication."

"The accuracy of the results depends on various factors, as some of the test folders tend to give us false positives, which makes a huge impact on the vulnerabilities."

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

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

"One of the challenges I have with AppSpider is that it gives you a lot of false positives, especially when compared to other solutions."

"The tech support is responsive but issues remain unresolved."

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