For high-security applications, you can configure connectors to run remotely behind firewalls, instead of hosting them in Managed Fusion. Also, some connectors support security trimming, which restricts query results based on user ID. In Managed Fusion 5.9.0 and later, connectors use graph security trimming. In Managed Fusion 5.8.1 and earlier, they use the security trimming stage.
Connectors are developed and released separately from Managed Fusion, although their functionality and compatibility is closely tied to Managed Fusion versions. Refer to the connector release notes for more information.
