Enabled by default. FortiNAC imports all the trusted CAs from the system’s OS (CentOS or FortiNAC-OS) to its local keystore. This allows FortiNAC to trust well-known root CAs automatically.

Once imported, the CA certificates are listed as Certificate Target “General Trusted CA” under System > Certificate Management > Trusted Certificates.

Used for trusting SSL connections with modeled network devices.
