Your Logs, Their Cloud: Why Data Ownership Defines Modern Detection & Response

A guide to understanding sovereignty, cost, and the true price of vendor-controlled data lakes.

Security teams have been conditioned to ship their logs into vendor-controlled data lakes, but that model is breaking. It creates sovereignty risks, hides cloud spend, inflates storage without adding detection value, and locks organisations into architectures they can’t control.

This blog post explains why modern detection must evolve beyond the “Your Logs, Their Cloud” pattern. Cloud waste is rising because log volume grows quietly within cloud space organisations already pay for, while the security value it delivers stays the same. Traditional SIEM and MDR tools amplify this problem by replicating and retaining data inside their own clouds, often far outside the organization’s governance.

If you’re rethinking data ownership, cloud waste, or vendor lock-in in your managed detection and response program, this guide explains what needs to change and how to start.
