Words from the team

The Security R&D team got established at SonarSource with the acquisition of RIPS Technologies. RIPS was known as a technology leader in static application security testing and for its in-depth web security research. At SonarSource, we are continuing these efforts to provide best-in-class technology and research with joint forces and knowledge.

What we do

Sonar was started by a team of developers that wanted to change the way code is built in an agile development process. The company was created to develop the open-source tool SonarQube, which is now the standard in code quality management with over 350,000 instances deployed today. Every day we are focused on solving developers’ next big problem.
