Complete code quality & AppSec in one unified platform.
Sonar is the AI code verification layer that closes the integrity gap — ensuring every line of code, whether written by a developer or an AI agent, meets security and quality standards before it ships.

SonarQube vs. Checkmarx
A side-by-side look at how SonarQube compares to Checkmarx across the capabilities engineering teams rely on.
Why engineering and security teams choose SonarQube
Unified platform — no tool sprawl, no stitching
Checkmarx One bundles SAST, SCA, DAST, and IaC into a single dashboard — but each module was acquired or built separately, and the "Fusion engine" correlation layer is post-processing, not native. Sonar operates from a single data model, a single quality gate framework, and a single reporting engine.
Advanced SAST that crosses boundaries
Sonar's advanced SAST performs cross-file taint analysis and dependency-aware data flow — tracking untrusted input across functions, files, and into third-party libraries without manual configuration. Sonar finds the vulnerabilities that exist at the intersection of your code and its dependencies: the ones that are hardest to spot and most expensive to miss.
Developer-first, not security-team-first
Sonar was built for developers from day one. SonarQube surfaces findings in the IDE, pull request, CLI, and pipeline — where developers actually work. Checkmarx was built for security teams and retrofitted into developer workflows. The result is friction, alert fatigue, and low developer adoption.
"We're not just keeping quality high; we're actually able to go faster because we’ve cleared a lot of that tech debt that’s been there for years. AI makes it easier to deliver velocity, but only if you provide the right context from tools like SonarQube.”
