SonarSource develops code quality and security analysis tools that scan source code to identify bugs, vulnerabilities, and code quality issues. The company's products analyze customer-provided content including source code, project metadata, code comments, commit messages, and integration data to generate analysis results. Their services integrate with third-party platforms such as GitHub, Bitbucket, GitLab, and Azure DevOps to enable authentication and code scanning workflows.

The company offers both cloud-based services and on-premises solutions that process code during development to help organizations identify security vulnerabilities and maintain code quality standards. Their analysis tools examine source code without requiring personal data, though they may incidentally process developer names and other information embedded in code comments or commit metadata when customers choose to scan such content.

SonarSource serves organizations across various industries, providing account management capabilities that allow companies to control user access, set permissions, and manage team usage of the platform. The company operates through direct sales as well as business partners, resellers, and distributors who help implement and deliver their services to enterprise customers. They maintain a community forum where users can share information and interact with other users of their products.
