InfraSonar is an IT infrastructure monitoring platform developed and maintained by Cesbit B.V. It watches servers, networks, certificates and cloud services, using agents (Linux, Windows, Docker, Kubernetes), probes (SNMP, VMware, MSSQL, Proxmox and others) and agentless checks. Usually an appliance running the agentcore and probes sits in the customer's environment and sends data to the cloud platform. It offers alerts, dashboards and an API.
Cesbit is a Dutch software company; no parent company or majority owner is named. According to the documentation, the platform runs on Google Cloud Platform, a US cloud provider. The privacy page states that all collected data is stored within the European Union; no specific region is given. Because the infrastructure belongs to a US company, the US CLOUD Act can be relevant even when data is stored in the EU. Sign-in uses a Google or Microsoft account. The vendor says it adheres to the GDPR and does not sell customer data. Check whether a data processing agreement is available and which dependency on US hosting you are prepared to accept.
