Executive SummaryUpdated on Feb 8, 2026

SonarQube and Checkmarx SAST compete in the static application security testing domain. Checkmarx SAST has the upper hand in security features, while SonarQube is favored for pricing and integration ease.

Features: SonarQube offers an open-source platform with comprehensive code quality analysis across multiple languages, excellent CI/CD integration, and SonarLint for local scanning. Checkmarx SAST provides advanced security testing capabilities, real-time code analysis, and extensive vulnerability coverage, meeting critical security needs.

Room for Improvement: SonarQube could enhance its security vulnerability identification and improve customer support options for premium users. Checkmarx SAST might benefit from reducing false positives, improving documentation for better user experience, and streamlining the complexity of its deployment.

Ease of Deployment and Customer Service: SonarQube is straightforward to deploy, ideal for teams accustomed to open-source solutions, but has limited professional support. Checkmarx SAST offers more complex deployment but comes with dedicated customer service, aiding larger enterprises with integration processes and support resources.

Pricing and ROI: SonarQube's open-source nature and lower setup costs offer immediate savings, appealing to cost-conscious teams. Although Checkmarx SAST requires a higher initial investment, it promises better long-term ROI for organizations prioritizing comprehensive security due to its superior security testing features.

Tharindu Malwenna

Senior Application Security Engineer at a newspaper with 5,001-10,000 employees

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.

Sr Software Engineering Supervisor at Mozarc Medical

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 most important feature is that Checkmarx protects our company against attacks."

"The CX1 is a unified platform that covers all components such as SAST, SCA, DAST, container scanning, and infrastructure code, which is quite beneficial because some clients need one-stop solutions for all their needs."

"The detailed reports from Checkmarx SAST help with our security process by showing details about which line is actually vulnerable, which is beneficial for the developers, and I do not have any suggestions or inputs on that area."

"This helps us a lot in identifying vulnerabilities in early stages, and the integration within the IDEs helps developers get the results into their IDE itself, making it easier for them to fix vulnerabilities."

"The most important feature is that Checkmarx protects our company against attacks."

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

"There are many options and examples available in the tool that help us fix the issues it shows us."

"The most valuable feature of SonarQube I have found to be the configuration that has allowed us to can make adjusts to the demands of the code review. It gives a specified classification regarding the skill, prioritization, and it is easy for me to review and make my code."

"SonarQube is good for checking and maintaining code quality."

"Integrate it into the developers' workbench so that they can bench check their code against what will be done in the server-based audit version."

"The solution's user interface is very user-friendly."

"Before you even compile, it can catch known vulnerability issues or patterns."

"I find SonarQube Cloud to be very user-friendly with an easy-to-use interface."

"Improve the code coverage and evaluates the technical steps and percentage of code being resolved."

Cons

"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."

"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."

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

"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."

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

"The main challenge with Checkmarx SAST is the price. The price is a challenge because Checkmarx SAST is a very big brand, and many mid-sized companies cannot afford it as they are very price-conscious."

"SonarQube could improve its static application security testing as per the industry standard."

"Currently requires multiple tools, lacking one overall tool."

"The Python code scan has so few rules that it is meaningless."

"This is a well-rounded solution, however, some features could be made available on the free version. The price of the solution could be reduced."

"I would also like SonarQube to be able to write custom scanning rules. More documentation would be helpful as well because some of our guys were struggling with the customization script."

"I need a solution that can bring together three key areas: vulnerabilities, static scanning, and misarchitecture. Currently, to achieve our expectations, we have to use more than one product, as some products excel at scanning for vulnerabilities but are poor at checking code quality."

"Expression of common vulnerabilities and exposures is not always current."

"We had some issues where the Quality Gate check sometimes gets stuck and it is unclear."
