Request security allows you to limit requests from the Grafana server by targeting requests generated by users, such as data source metric queries and alert notifications.
This can be used to limit access to internal systems that the server Grafana runs on can access but that users of Grafana should not be able to access. This feature does not affect traffic from the Grafana users browser.
> **Note:** Available in [Grafana Enterprise]({{< relref "../enterprise" >}}) version 7.4 and later, and [Grafana Cloud Pro and Advanced]({{< ref "/docs/grafana-cloud" >}}).
