ROI

Sentiment score
5.6
Checkmarx One enhances security by automating vulnerability detection, reducing costs, and improving development efficiency through CI/CD integration.
Sentiment score
6.2
Klocwork enhances code quality and compliance, improving efficiency in defect resolution, especially in automotive sectors, despite ROI measurement challenges.
Sentiment score
6.6
SonarQube enhances code quality, reduces defects, and saves time by integrating with CI/CD, aiding compliance and security.
Overall, between the fast scanning, automation, automatic reporting, and easy detection, it has reduced manual effort enough that we did not need an extra reviewer, even as our codebase or team size grew.
Senior GenAI Engineer at a tech vendor with 10,001+ employees
Based on my interactions with the clients, I can tell that there is a return on investment because if something is not profitable and it's not helping to save costs or vulnerabilities, clients wouldn't come back to renew their license year after year.
Chief Technology Officer at 3CS Aquarah Limited
The main ROI factors include efficiency and how we meet compliance standards for various automotive requirements.
Manager, Quality, Functional Safety, Cybersecurity Embedded Processing at a manufacturing company with 10,001+ employees
It is easily integrable with the CI/CD pipeline and supports multiple projects with its extensive plugin options.
Security Analyst at Dover Corporation
I have seen a return on the investment from SonarQube Server (formerly SonarQube) because the value it adds relates to static code analysis and vulnerability assessments needed for our FDA approval process.
Sr Software Engineering Supervisor at Mozarc Medical
We see productivity increasing based on the fact that the code review is mostly automated, allowing the developer to fix the code themselves before assigning it to someone else to review, thus receiving that ROI.

Room For Improvement

Checkmarx One needs enhancements in accuracy, speed, integration, UI, support, pricing, and features for enterprise usability.
Klocwork needs improved language support, flexible reporting, better integration with Agile DevOps, and enhanced static and dynamic analysis.
SonarQube users seek enhanced security, third-party integrations, language support, UI, documentation, automation, and advanced code analysis features.
Integration into the IDE being used would be beneficial so that code does not need to be uploaded to the website and an IDE-friendly report could be generated.
Senior Software Engineer at a financial services firm with 10,001+ employees
It could suggest how the code base is written and automatically populate the source code with three different solution options to choose from.
Specialist Leader at Deloitte
If you can improve the speed optimization, it takes around 30 to 40 minutes for checking a build. If you can make it within five minutes or 10 minutes, that would be great.

Setup Cost

Checkmarx One is often costly but provides quality and security, with costs varying by team size and selected modules.
Klocwork's flexible pricing models are valued, though opinions vary on cost-effectiveness, catering to diverse organizational needs.
SonarQube offers free and paid editions, with costs varying by features; the free version suits basic needs.
For a small team under 50 developers, normal expenses come under 30 to 60K.
Senior Solution Architect | L3+ Systems & Cloud Engineer | SRE Specialist at Canada Cloud Solution
Due to the number of years I've implemented Checkmarx One, there are rebates and discounts from the OEM which makes it a lot more profitable.
Chief Technology Officer at 3CS Aquarah Limited

Klocwork was competitively priced, making it a cost-effective solution for us.
Application Development Team Lead at Miura Pay
I would rate the pricing for SonarQube Server (formerly SonarQube) as an 8, where 1 is very cheap and 10 is very expensive, because Coverity is very expensive, and while SonarQube is not cheap, it is still less expensive than Coverity.
Sr Software Engineering Supervisor at Mozarc Medical
They always offer around a two-year contract, but we always take a one-year contract because it's expensive.
Head of Software Engineering at ronaldmariah@gmail.com

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.

Experience with compliance improvements and efficiency boosts but static analysis engine shows a need for enhancement
One area for improvement is that when customers use different static analysis tools, they report more issues compared to Klocwork. The static analysis engine of Klocwork has areas that need improvement. Customers using different static analysis tools report more issues than with Klocwork, indicating that Klocwork's engine is not as superior. Klocwork should be able to analyze large codebases efficiently, supporting a desktop version for periodic small delta changes before pushing to the server.

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.
