French hybrid IT infrastructure and network monitoring platform, born from an open-source project in 2003.

Centreon is an IT infrastructure, network and application monitoring platform published by Centreon SAS, a company legally registered in Paris, France. It grew out of an open-source project started in 2003 and the company was incorporated in 2005.

The platform monitors hybrid environments spanning cloud-native and containerized workloads, legacy on-premises systems, and OT/IoT infrastructure from a single console, competing with tools like Datadog and New Relic for full-stack observability use cases. It ships in a free, GPL-licensed “Open Source” edition alongside commercial Business and MSP editions with added automation and scale.

Centreon reports hundreds of customers and hundreds of thousands of users across dozens of countries, making it one of the more established European players in infrastructure monitoring.
