About Stream Scanning
Stream scanning is based on the simple observation that network traffic travels in streams. The STM150 scan engine starts receiving and analyzing traffic as the stream enters the network. As soon as a number of bytes are available, scanning commences. The scan engine continues to scan more bytes as they become available, while at the same time another thread starts outputting the bytes that have been scanned.
This multi threaded approach, in which the receiving, scanning, and outputting processes occur concurrently, ensures that network performance remains unimpeded. The result is that the time to scan a file is up to five times faster than traditional antivirus solutions – a performance advantage that is easily noticeable to the end user.
Stream scanning also enables organizations to withstand massive spikes in traffic, as in the event of a malware outbreak.
