Featured Reviews

Syed Hasan - PeerSpot reviewer
Partner experiences excellent technical support and seamless initial setup
In my opinion, if we are able to extract or show the report, and because everything is going towards agent tech and GenAI, it would be beneficial if it could get integrated with our code base and do the fix automatically. It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from. This would be really helpful.
Henry Mwawai - PeerSpot reviewer
Automated code reviews and good scalability with custom rule adaptability
We use Semgrep to check custom user pipelines and test their claims for any vulnerabilities. We process the code by passing it through the testing process for any operability issues before sending feedback to the developers and providing the final product. This is part of the static testing…

Quotes from Members

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

Pros

"The setup is fairly easy. We didn't struggle with the process at all."
"The SAST component was absolutely 100% stable."
"It is a stable product."
"The only thing I like is that Checkmarx does not need to compile."
"The report function is the solution's greatest asset."
"I have seen a return on investment from Checkmarx One."
"The features and technologies are very good. The flexibility and the roadmap have also been very good. They're at the forefront of delivering the additional capabilities that are required with cloud delivery, etc. Their ability to deliver what customers require and when they require is very important."
"The most valuable features of Checkmarx are the automation and information that it provides in the reports."
"The most valuable feature is the ability to write our custom rules."
 

Cons

"I would like to see the DAST solution in the future."
"When we first ran it on a big project, there wasn't enough memory on the computer. It originally ran with eight gigabytes, and now it runs with 32. The software stopped at some point, and while I don't think it said it ran out of memory, it just said "stopped" and something else. We had to go to the logs and send them to the integrator, and eventually, they found a memory issue in the logs and recommended increasing the memory. We doubled it once, and it didn't seem enough. We doubled it again, and it helped."
"Checkmarx is not good because it has too many false positive issues."
"Checkmarx could be improved with more integration with third-party software."
"C, C++, VB and T-SQL are not supported by this product. Although, C and C++ were advertised as being supported."
"Checkmarx has a slightly difficult compilation with the CI/CD pipeline."
"Creating and editing custom rules in Checkmarx is difficult because the license for the editor comes at an additional cost, and there is a steep learning curve."
"Checkmarx being Windows only is a hindrance. Another problem is: why can't I choose PostgreSQL?"
"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."
 

Pricing and Cost Advice

"The number of users and coverage for languages will have an impact on the cost of the license."
"We have a subscription license that is on a yearly basis, and it's a pretty competitive solution."
"It is not expensive, but sometimes, their pricing model or licensing model is not very clear. There are similar variables, such as projects or developers, and sometimes, it is a little bit confusing."
"I would rate the solution’s pricing an eight out of ten. The tool’s pricing is higher than others and it is for the license alone."
"I believe pricing is better compared to other commercial tools."
"It is an expensive solution."
"The average deal size was usually anywhere between $120K to $175K on an annual basis, which could be divided across 12 months."
"It is the right price for quality delivery."
