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.

Though a stable tool, the UI needs improvement

Kiuwan can improve its UI a little more. The user experience can be made better. Kiuwan offers a user interface that is similar to the one offered by Windows 7 or Windows 98, which I saw when I ran the tool and tried to scan the repository to find the security issues. The product's UI has certain shortcomings, where improvements are required.

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 feature that I have found most valuable is that its number of false positives is less than the other security application platforms, its ease of use is another good feature, and it also supports most of the languages."

"We were using HPE Security Fortify to scan code for security vulnerabilities, but it can scan only after a successful compile, and if the code has dependencies or build errors the scan fails, while with Checkmarx pre-compile scanning is seamless and allows us to scan more code."

"As an InfoSec consulting company, we come across major challenging projects, and Checkmarx has made life easy by reducing manual efforts in using test cases against any vulnerability found during source code reviews while intelligently finding the latest vulnerabilities beyond the OWASP Top Ten."

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

"It can integrate very well with DAST solutions. So both of them are combined into an integrated solution for customers running application security."

"The setup is fairly easy. We didn't struggle with the process at all."

"The solution is always updating to continuously add items that create a level of safety from vulnerabilities, and they are always ahead of the game when it comes to finding any vulnerabilities within the database, so I am assured that when I am scanning my product those vulnerabilities are identified at very initial stages, giving my development team more time to react."

"We have used this product to verify the dev department's code in order to minimize security holes."

More Checkmarx One pros

"We are using this solution to increase the quality of our software and to test the vulnerabilities in our tools before the customers find them."

"I advise using Kiuwan because it's very straightforward and totally easy to understand."

"I like that I can scan the code without sending it to the Kiuwan cloud. I can do it locally on my device. When the local analyzer finishes, the results display on the dashboard in the cloud. It's essential for security purposes to be able to scan my code locally."

"I have found the security and QA in the source code to be most valuable."

"The most valuable feature of the solution stems from the fact that it is quick when processing and giving an output or generating a report."

"Customer service is excellent."

"The technical support is very good, and we have received valid answers to our questions."

"I find it immensely helpful because it's not just about generating code; it's about ensuring efficiency in the execution."

More Kiuwan pros

"We use it as a gatekeeper for our external developers to follow the rules; if they don't comply with the rules within the source code, they cannot commit."

"While annoying occasionally with its issue reports, it is actually an invaluable source of better knowledge and applying it in practice to your solutions."

"When comparing other static code analysis tools, SonarQube has fewer false-positive issues being reported. They have a lot of support for different tech stacks. It covers the entire developer community which includes Salesforce or it could be the regular Java.net project. It has actually sufficed all the needs in one tool for static code analysis."

"The SonarQube dashboard looks great."

"The most valuable features are the dashboard reports and the ease of integrating it with Jenkins."

"We advise all of our developers to have this solution in place."

"The solution offers a very good community edition."

"The most valuable features are code scanning and Quality Gates."

More SonarQube pros

Cons

"It provides us with quite a handful of false positive issues."

"Checkmarx is not good because it has too many false positive issues."

"Checkmarx could improve the REST APIs by including automation."

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

"Updating and debugging of queries is not very convenient."

"We had to lock the number of CPUs used to not crash the Checkmarx Audit."

"It provides us with quite a handful of false positive issues. If Checkmarx could reduce this number, it would be a great tool to use."

"Some were valid and some were not applicable for us based on the scenario."

More Checkmarx One cons

"The solution seems to give us a lot of false positives. This could be improved quite a bit."

"The QA developer and security could be improved."

"I would like to see better integration with the Visual Studio and Eclipse IDEs."

"The product's UI has certain shortcomings, where improvements are required."

"Perhaps more languages supported."

"For mobile development, we are not too experienced, and it is not the perfect tool because the integration with certain products is very manual."

"The development-to-delivery phase."

"Integration of the programming tools could be improved."

More Kiuwan cons

"The solution needs to improve its customization and flexibility."

"SonarQube Server (formerly SonarQube) could be improved on the reporting front. Instead of grouping, I would prefer to scan the code as part of development and then generate a report on a daily basis among different units or projects, which is currently complicated."

"There are limitations to the free version that limit development options as far as languages."

"We did have some trouble with the LDAP integration for the console."

"Ease of use/interface."

"New plug-ins should be integrated into SonarCloud to give more flexibility to the product."

"The only pain area for us is due to the fact that we purchased the 1 million lines of code license for now."

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

More SonarQube cons

Pricing and Cost Advice

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

"The solution is costly."

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

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

"It is the right price for quality delivery."

"The average deal size was usually anywhere between $120K to $175K on an annual basis, which could be divided across 12 months."

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

"We're using a commercial version of Checkmarx, and we paid for the solution for one year. The price is high and could be reduced."

More Checkmarx One pricing and cost advice

"Kiuwan is an open-source solution and free to use."

"It follows a subscription model. I think the price is somewhere in the middle."

"Nothing special. It's a very fair model."

"The price of Kiuwan is lower than that of other tools on the market."

"This solution is cheaper than other tools."

"I recommend contacting a sales person who will create the best plan payment plan for you, as we did."

"Check with your account manager."

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

"The solution is cheaper than other products."

"For the Community edition, there is no extra cost. It's totally free. The Enterprise edition, Data Center edition, and Developer edition are the paid versions."

"We are using the community version of the solution and we plan on purchasing licenses for the upgraded version soon. There is a limitation on how many lines of code can be scanned and this is why we are going to purchase a license for an increased amount."

"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."

"I am using the free version of the solution."

"We have a license with 125,000 lines of code. We did not purchase a lot of lines but it is specific to our code environment."

"We are using the open-source community version, but there are enterprise licenses available."
