If you have ever built a LEGO set, then you have a general idea of how telemetry works. Telemetry starts with individual data points, just like your LEGO build starts with a box of bricks. In complex IT environments, your security telemetry is spread across different technologies and monitoring tools, just like in a large build your LEGO bricks come separated into smaller, individually numbered bags. In both cases, the individual bricks or data points aren’t special.

Security teams often struggle to keep up with rapidly evolving threats, especially when they have to manually manage detection rules. Without automation or version control, it's difficult to maintain consistency across environments, track changes, or deploy updates quickly. Datadog Cloud SIEM supports detection as code, a structured approach to authoring, testing, deploying, and managing detection rules using code and infrastructure-as-code tools like Terraform.
