What is Cribl Guard background detection?

Mar 10, 2026

Security and compliance teams need to know exactly what sensitive data is flowing through their environments and where it’s going. ​​Because surprise PII is no one’s favorite kind of surprise.

Meanwhile, upstream teams are shipping new apps, changing schemas, adding fields, and generally moving fast.

However, you can only manage and protect the data you currently know of and expect.

But sensitive data has a habit of showing up where no one expected it…

That’s why in Cribl Stream 4.17, we’re introducing background detection, an AI-powered capability in Cribl Guard that continuously analyzes data flowing through Pipelines to uncover previously unknown sensitive data before it causes an issue.
