Network File Copy (NFC) provides a file-type-aware FTP service for vSphere components. ESXi uses NFC for operations such as copying and moving data between datastores by default. You can disable and reenable SSL certificate validation for NFC operations.

About this task

When SSL over NFC is enabled, connections between vSphere components over NFC are secure. This connection can help prevent man-in-the-middle attacks within a datacenter.

Because using NFC over SSL causes some performance degradation, you might consider disabling this advanced setting in some development environments.
