Bentley Systems develops software for designing, building and operating infrastructure, including MicroStation (CAD), OpenRoads Designer, ProjectWise and STAAD. The iTwin Platform is a cloud platform for infrastructure digital twins. For geospatial use, Bentley acquired Cesium in September 2024, the developer of the open-source library CesiumJS (Apache 2.0) for 3D globes and maps in the browser, of the streaming service Cesium ion and of the open 3D Tiles standard. Products are delivered as desktop software, cloud services and APIs.
Bentley Systems is headquartered in Exton, Pennsylvania, United States, and is listed on Nasdaq (BSY). As a US company it falls under US jurisdiction, which is relevant to the CLOUD Act. According to its developer documentation, the iTwin Platform runs in several data centers worldwide, including West Europe, North Europe and UK South; not all services are available in every data center. CesiumJS is open source, while Bentley's other products are commercial. A European organisation should confirm the required data region for each service.
