IntelliScan optimizes performance by examining file headers using true file type recognition and scanning only file types known to potentially harbor malicious code. True file type recognition helps identify malicious code that can be disguised by using a harmless file extension type. The following are just a couple of the benefits IntelliScan offers to administrators:
Performance optimization: Server system resources allotted to scan will be minimal. Using IntelliScan will not interfere with other crucial applications running on the server.
Time saving: Since IntelliScan uses true file type identification, the scan time for running IntelliScan is significantly less than the time required for all attachment files. This means that only files with a greater risk of being infected are scanned. This time difference is noticeable when you use IntelliScan with Manual scan.
