This category covers network monitoring, infrastructure and server monitoring, log management, observability platforms and the tools that collect metrics, traces and alerts. IT and security teams use them to see availability and performance, find faults early, investigate incidents and show that services meet agreed levels.
Telemetry is sensitive in a way that is easy to overlook. Logs and traces can contain IP addresses, usernames, internal hostnames, query strings and sometimes personal data or credentials, and together they form a map of your infrastructure. A hosted service therefore receives a detailed picture of your environment, and its agents often run with broad privileges on your systems. Volume-based pricing can also push teams to drop or truncate logs, which weakens their own investigations. Check how retention, masking of sensitive fields and access by the provider's staff are handled.
When choosing a European option, look for self-hosted or EU-hosted deployment, open agents and open standards for metrics and traces, the ability to export historical data, and role-based access. Open-source stacks avoid dependence on a single vendor, though they require operating capacity. Also check how the tool itself is patched, because a monitoring platform is a high-value target.
