Enable secure development workflows while identifying opportunities for faster scans and improved AI guidance

Checkmarx One is a very strong platform, but there are several areas where it can improve to support modern DevSecOps workflows even better. For example, better real-time developer guidance is needed. The IDE plugin should offer richer AI-powered auto-fixes similar to SNYK Code or GitHub Copilot Security, as current guidance is good but not deeply contextual for large-scale enterprise codebases. This matters because it reduces developer friction and accelerates shift-left adoption. More transparency control over the correlation engines is another need. The correlation engine is powerful but not fully transparent. Users want to understand why vulnerabilities were correlated or de-prioritized, which helps AppSec teams trust the prioritization logic. Faster SAST scan and more language coverage is needed since SAST scan can still be slow for very large mono-repos and there is limited deep support for new language frameworks like Rust and Go, along with advanced coverage for serverless-specific frameworks. This matters because large organizations want sub-minute scans in CI/CD as cloud-native ecosystems evolve fast. A strong API security module is another area for enhancement. API security scanning could be improved with active testing, API discovery, full Swagger, OpenAPI, drift detection, and schema-based fuzzing. This is important as API attacks are one of the biggest AppSec risks in 2025. Checkmarx One is strong, but I see a few areas for improvement including faster SAST scanning for large mono-repos, deeper language framework support, more transparent correlation logic, and stronger API security that includes discovery and runtime context. The IDE plugin could offer more AI-assisted fixes, and the SBOM lifecycle tracking can evolve further. Enhancing integration with SIEM and SOAR would also make enterprise adoption smoother, and these improvements would help developers and AppSec teams move faster with more accuracy.

Nice interface, quick to deploy, and easy to expand

This is the first time I've used this kind of software. It was the only one we could apply to analyze with MISRA rules. At my new company, I tried to use Klocwork. I tried to use it, just once so I cannot compare it exactly with CodeSonar. I also have a plugin for my Visual Studio and I try to make it work. It's not easy, however, I don't think that we have this kind of functionality with CodeSonar. It can do some incremental analysis. However, since this feature is also available on CodeSonar, it would be a good idea to have a plugin on Visual Studio just to have a quick analysis.

Quotes from Members

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

Pros

"The most valuable features of Checkmarx are the automation and information that it provides in the reports."

"The most valuable features are the easy to understand interface, and it 's very user-friendly."

"The only thing I like is that Checkmarx does not need to compile."

"It shows in-depth code of where actual vulnerabilities are."

"We use the solution for dynamic application testing."

"It gives the proper code flow of vulnerabilities and the number of occurrences."

"The setup is very easy. There is a lot of information in the documents which makes the install not difficult at all."

"The reports are very good because they include details on the code level, and make suggestions about how to fix the problems."

More Checkmarx One pros

"The most valuable features of CodeSonar were all the categorized classes provided, and reports of future bugs which might occur in the production code. Additionally, I found the buffer overflow and underflow useful."

"The tool is very good for detecting memory leaks."

"It has been able to scale."

"There is nice functionality for code surfing and browsing."

"What I like best about CodeSonar is that it has fantastic speed, analysis and configuration times. Its detection of all runtime errors is also very good, though there were times it missed a few. The configuration of logs by CodeSonar is also very fantastic which I've not seen anywhere else. I also like the GUI interface of CodeSonar because it's very user friendly and the tool also shows very precise logs and results."

"CodeSonar’s most valuable feature is finding security threats."

"The most valuable feature of CodeSonar is the catching of dead code. It is helpful."

Cons

"The resolutions should also be provided. For example, if the user faces any problem regarding an installation due to the internal security policies of their company, there should be a resolution offered."

"I would like to see the tool’s pricing improved."

"Checkmarx One is often down when the cloud provider experiences issues. A more fail-tolerant solution needs to be created."

"There are some downtimes when Checkmarx One is being upgraded to the latest version or some improvement is there."

"One area for improvement in Checkmarx is pricing, as it's more expensive than other products."

"The cost per user is high and should be reduced."

"Its pricing model can be improved. Sometimes, it is a little complex to understand its pricing model."

"I really would like to integrate it as a service along with the SAP HANA Cloud Platform. It will then be easy to use it directly as a service."

More Checkmarx One cons

"CodeSonar could improve by having better coding rules so we did not have to use another solution, such as MISRA C."

"In a future release, the solution should upgrade itself to the current trends and differentiate between the languages. If there are any classifications that can be set for these programming languages that would be helpful rather than having everything in the generic category."

"In terms of areas for improvement, the use case for CodeSonar was good, but compared to other tools, it seems CodeSonar isn't a sound static analysis tool, and this is a major con I've seen from it. Right now, in the market, people prefer sound static analysis tools, so I would have preferred if CodeSonar was developed into a sound static analysis tool formally, in terms of its algorithms, so then you can see it extensively used in the market because at the moment, here in India, only fifty to sixty customers use CodeSonar. If the product is developed into a sound static analysis tool, it could compete with Polyspace, and from its current fifty customers, that number could go up to a hundred."

"The scanning tool for core architecture could be improved."

"There could be a shared licensing model for the users."

"It would be beneficial for the solution to include code standards and additional functionality for security."

"It was expensive."

Pricing and Cost Advice

"The pricing is competitive and provides a lower TCO (total cost of ownership) for achieving application security."

"It is an expensive solution."

"The solution is costly."

"The number of users and coverage for languages will have an impact on the cost of the license."

"We have purchased an annual license to use this solution. The price is reasonable."

"Before implementing the product I would evaluate if it is really necessary to scan so many different languages and frameworks. If not, I think there must be a cheaper solution for scanning Java-only applications (which are 90% of our applications)."

"It is a good product but a little overpriced."

"It's relatively expensive."

More Checkmarx One pricing and cost advice

"The solution's price depends on the number of licenses needed and the source code for the project."

"The application’s pricing is high compared to other tools."

"Our organization purchased a license to use the solution."

"Pricing is a bit costly."
