# File Integrity Operator overview {#fio-overview}

The File Integrity Operator continually runs file integrity checks on the cluster nodes. It deploys a DaemonSet that initializes and runs privileged Advanced Intrusion Detection Environment (AIDE) containers on each node, providing a log of files that have been modified since the initial run of the DaemonSet pods.

> [!NOTE]
> File Integrity Operator is not supported on HCP clusters.
