The BIOS-level signature and integrity checking has been enhanced by enforcing each FortiOS GA firmware image, AV engine file, and IPS engine file to be dually-signed by the Fortinet CA and a third-party CA. The BIOS verifies that each file matches their secure hash as indicated by their certificates. Users are warned when there is a failed integrity check, and the system may be prevented from booting depending on the severity and the BIOS security level.

Signature checking occurs when the FortiOS firmware, AV, and IPS engine files are uploaded. This allows the FortiGate to warn users of potential risks involved with uploading an unauthenticated file.

The outcome of the signature and integrity check depends on the security level configured in BIOS and the certificate authority that signed the file.
