ESoft's ThreatWall 200 1U appliance stopped 67 of the test malware instances, and it imposed a latency of 18 msec to 25 msec as it forwarded nonexecutable Internet messages to clients.

For executable files, the ThreatWall 200 needed 110 msec to 190 msec to analyze packets for potential malware. The device looks for definition updates automatically every 30 minutes, a frequency that can be changed to daily. The eSoft appliance blocked phone-home attempts, and unlike the other appliances, it scans FTP, SMTP and POP3 traffic in addition to HTTP as it looks for malware.

The ThreatWall 200 uses file signatures, URLs and IP addresses to recognize malware. For each spyware event, it records date, time, source IP address, destination IP address, spyware ID (name), network domain and type of malware. The ThreatWall 200 uses SNMP to integrate with a network-management system.
