OfficeScan clients can use one of two scan methods when scanning for security risks. The scan methods are smart scan and conventional scan.
Smart Scan
Clients that use smart scan are referred to as smart scan clients in this document. Smart scan clients benefit from local scans and in-the-cloud queries provided by File Reputation Services.
Conventional Scan
Clients that do not use smart scan are called conventional scan clients. A conventional scan client stores all OfficeScan components on the client computer and scans all files locally.
