OneLake Guard

OneLake Guard is lightweight data observability for Microsoft Fabric. It automatically watches Delta tables in OneLake — schema drift, volume and quality anomalies, Direct Lake health — with no rule configuration and no Spark notebooks. Results land in your Lakehouse + Power BI. For $49/month, not an enterprise observability contract.

What it is

Fabric-native trust signals — simple to install, simple to use

OneLake Guard continuously checks OneLake Delta tables and writes results back into a Lakehouse you choose, with a Direct Lake Power BI report already deployed in Fabric. You stay in the environment you already know.

Install in minutes

Deploy from Azure Marketplace into your subscription. No new vendor onboarding — billing stays on the Azure account you already use.

Almost zero config

Add the service principal to the workspaces you want monitored (and Contributor on the output Lakehouse). Scans and detectors run automatically.

No new UI to learn

Fully integrated with Fabric. Review anomalies in the deployed report — you never have to leave Fabric for a separate observability console.
