Attestation is a process that verifies the integrity of a device. It can check if a device has been rooted or is running unauthorized firmware. You might use this feature to ensure you are not handling private or confidential data on a device that might be compromised and be vulnerable to malware.
All Knox devices, beginning with the Galaxy Note 3, support attestation. Devices older than Galaxy Note 3 do not support attestation.
