Some anti-spyware appliances operate as Web proxies with the ability to scan SSL-encrypted HTTP (e.g., Finjan Vital Security Web Appliance, Bluecoat SG). Some watch for standard protocol deviations, vulnerabilities and associated exploits (e.g., Aladdin eSafe Gateway). Some appliances focus on spyware (e.g., 8e6 R30CK) Enterprise Internet Filter), while others combine anti-spyware with many other network defenses (e.g., eSoft Threatwall). Finally, many anti-spyware appliances operate as in-line gateways (e.g., Facetime RTGuardian, McAfee Secure Web Gateway), but some offer out-of-band spyware detection (e.g., Mi5 Enterprise SpyGate).

* Anti-Spyware Services-Managed Security services are generally aimed at those short on IT staff, security expertise, and capital. As spyware concerns grow, new managed anti-spyware services are expected to emerge for individuals and businesses.

Windows Live OneCare illustrates this trend at the desktop. OneCare Protection Plus is a subscription-based managed security service that combines desktop anti-spyware, anti-virus, and firewall defenses. OneCare primarily targets individual consumers, but can also be used by small businesses that prefer not to configure, monitor, or maintain desktop security programs. Other vendors have also announced subscription-based desktop security services that will include antispyware, notably McAfee Falcon and Symantec Norton 360 (aka Genesis).Continued
