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.

It provides us with more in-depth visibility into ongoing attacks.

I rate Contrast Security Protect eight out of 10. Overall, it's a solid product, but I deduct a couple of points because of the interface and some shortcomings in the reporting. If you have a large enterprise where you're dealing with a lot of servers, then it makes sense not to use the internal MySQL database. You should use something like Oracle or Microsoft SQL, but if you don't have many transactions, the embedded MySQL database works great.

Gains control over rule customization and achieves reliable vulnerability assessment

The deployment process took me about 2 or 3 hours to deploy SonarQube Server (formerly SonarQube), although I do not remember exactly since it was done about 2 years back. Currently, about 10 of my developers are using SonarQube Server (formerly SonarQube) in my company. I do not have plans to increase the usage of SonarQube Server (formerly SonarQube) in the future as there will not be any requirement to increase. I am a senior software engineer and supervisor at Mozark Medical. My corporate email address is karthik.k.a.r.t.h.i.k.h.a.r.p.a.n.h.a.l.l.i@mozarkmedical.com. Overall, I would rate SonarQube Server (formerly SonarQube) as a 9 out of 10.

Quotes from Members

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

Pros

"The product's most valuable feature is static code and supply chain effect analysis. It provides a lot of visibility."

"The solution has good performance, it is able to compute in 10 to 15 minutes."

"In summary, this is a good application that you can use to scan every code language."

"The most valuable features of Checkmarx are its integration with multiple SCM solutions and CICD tools, its ability to scale according to user licenses, and the quick scanning process."

"The SAST component was absolutely 100% stable."

"Less false positive errors as compared to any other solution."

"The main advantage of this solution is its centralized reporting functionality, which lets us track issues, then see and report on the priorities via a web portal."

"The most valuable features of Checkmarx are the SCA module and the code-checking module. Additionally, the solutions are explanatory and helpful."

More Checkmarx One pros

"The Protect solution allows applications to continue to run, even with known vulnerabilities, but will report or block attempts to exploit the vulnerabilities."

"Contrast Security's support is great. They're willing to spend a lot of time on your problem."

"The solution has excellent real-time capabilities."

"The product gives a few false positives. We get 99 percent true positives."

"Protect provides us with more in-depth visibility into ongoing attacks."

"This product has helped us improve the quality of code within the business and ensure all new developers keep to a similar code convention per project."

"The integrations SonarQube provides with our software delivery pipeline are very seamless."

"The integration with Atlassian Jira is very useful and it works very well."

"We have seen a decrease of about 25% of issues from since we first started using it a few months ago, and my team code bases are getting better."

"It is a good deal compared to all other tools on the market."

"Using SonarQube has helped us to identify areas of technical debt to work on, resulting in better code, fewer vulnerabilities, and fewer bugs."

"This is a good solution if you are looking for good coverage, quality, and vulnerabilities to be highlighted."

"I'm not implementing the solutions. However, I've talked to the people who deploy the tools, and they are happy with how easy setting up SonarCloud is."

More SonarQube pros

Cons

"Checkmarx being Windows only is a hindrance. Another problem is: why can't I choose PostgreSQL?"

"Vulnerability details: Reduce false positive results and improve it by providing more details how I can resolve the vulnerability."

"They can support the remaining languages that are currently not supported."

"In terms of dashboarding, the solution could provide a little more flexibility in terms of creating more dashboards. It has some of its own dashboards that come out of the box. However, if I have to implement my own dashboards that are aligned to my organization's requirements, that dashboarding feature has limited capability right now."

"It would be really helpful if the level of confidence was included, with respect to identified issues."

"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."

"The stability of Checkmarx could improve. We're having issues with it, and the scan reliability is sometimes impacted so we sometimes have to restart the services to allow scans out of the queue."

"The default module that provides statistics is basic, and you need more elaborate information to do vulnerability management."

More Checkmarx One cons

"There's room for improvement in the initial setup."

"We're not using it much anymore because we had some performance issues."

"Protect's reporting GUI is very basic. To get all statuses from the APIs, we needed to write our own KPI dashboard to provide reports."

"Contrast Security Protect needs to improve integration."

"This product is good but it is not meant to be a single solution for all issues."

"There is no automation. You need to put the code there and test. You then pull the results and put them back in the development environment. There is no integration with the development environment. We would like it to be integrated with our development environment, which is basically the CI/CD pipeline or the IDE that we have."

"We had some issues with the scanner."

"The solution could improve the management reports by making them easier to understand for the technical team that needs to review them."

"SonarQube could be improved with more dynamic testing—basically, now, it's a static code analysis scan. For example, when the developer writes the code and does the corresponding unit test, he can cover functional and non-functional. So the SonarQube could be improved by helping to execute unit tests and test dynamically, using various parameters, and to help detect any vulnerabilities. Currently, it'll just give the test case and say whether it passes or fails—it won't give you any other input or dynamic testing. They could use artificial intelligence to build a feature that would help developers identify and fix issues in the early stages, which would help us deliver the product and reduce costs. Another area with room for improvement is in regard to automating things, since the process currently needs to be done manually."

"I wouldn't say that isn't fully scalable. It's damn slow. It takes a lot of time parsing an average size codebase."

"It would be better if SonarQube provided a good UI for external configuration."

"In the next release, I would like to have notifications because now, it is a bit difficult."

Pricing and Cost Advice

"The interface used to create custom rules comes at an additional cost."

"Its price is fair. It is in or around the right spot. Ultimately, if the price is wrong, customers won't commit, but they do tend to commit. It is neither too cheap nor too expensive."

"We got a special offer for a 30% reduction for three years, after our first year. I think for a real source-code scanning tool, you have to add a lot of money for Open Source Analysis, and AppSec Coach (160 Euro per user per year)."

"If you want more, you have to pay more. You have to pay for additional modules or functionalities."

"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)."

"The solution is costly."

"The solution's price is high and you pay based on the number of users."

"I believe pricing is better compared to other commercial tools."

Information not available

"The costs for this application, for the kind of job it does, are pretty decent."

"The tool's pricing is reasonable."

"There is both a free and licensed version. The free version has limitations on development languages and support."

"SonarQube is a cost-effective solution."

"The price of SonarCloud is not expensive, it goes by the lines of code. 1 million lines per code are approximately 4,000 USD per year. If you need 2 million lines of code you would double the annual cost."

"The price of this solution is more expensive than competitors. However, it works better than competitors."

"SonarQube enterprise, I am not sure of the price but from what I understand they are charging a fee. It's is not clear if it is an annual fee or a one-off."

"We are using the free, unlicensed version."
