 How to Install and Configure the Symantec Endpoint Protection (SEP) Shared Insight Cache (SIC).


The Symantec Endpoint Protection Shared Insight Cache eliminates the need to scan files in a virtualized environment that Symantec Endpoint Protection has determined are clean. When Symantec Endpoint Protection scans a file for threats and determines it is clean, the client submits information about the file to Shared Insight Cache. When another client subsequently attempts to scan the same file, the client can query Shared Insight Cache to determine if the file is clean. If the file is clean, the client can bypass virus scanning on that particular file. If the file is not clean, the client scans the file for viruses and submits those results to Shared Insight Cache.

NOTE: Shared Insight Cache is only available for the clients that perform scheduled scans and manual scans.

Shared Insight Cache runs independently of Symantec Endpoint Protection. However, you must configure Symantec Endpoint Protection Manager to specify the location of Shared Insight Cache so that your clients can communicate with Shared Insight Cache. No special license is required to install or run Shared Insight Cache.
