II. Virus Scanning

It is estimated that 87 percent of all viruses, worms, and trojans are transmitted through e‐mail messages according to International Computer Security Association (ICSA, April 2002). Protecting companies networks from potential virus attacks is the number one priority among IT professionals.

XcellHost E‐mail Security Service includes multi‐stage virus scanning to block virtually all known virus formats. Virus definitions are updated every ten minutes, 24x7, sometimes even before the public release of new virus signatures. Oriensoft XcellHost E‐mail Security Service leverages its world‐class infrastructure to deliver reliable, secure, and virus‐free e‐mail to customers.

Virus Scanning stage of the service offers:

􀀹 An intermediate buffer that protects the corporate mail system from possible attacks.
􀀹 Thorough scanning of incoming mail to virtually eliminate all viruses.
􀀹 Up‐to‐date virus signature through rapid updates to the virus engines.

Multi‐Engine Virus Scanning

XcellHost uses two of three antivirus engines for scanning and cleaning e‐mail: Kaspersky, Symantec, and Trend Micro. The scanning engines review and clean the e‐mail before it hits the companies network, ensuring the delivery of clean bandwidth and virus‐free IP connections.

XcellHost’s continued alliances with its antivirus partners ensure early warning and effective blocking for companies, with virus updates installed every 10 minutes. Like the spam filter, XcellHost’s virus filter enables administrators to modify the virus filters much like the spam filters. By default, all incoming mail is processed through the virus filters.

XcellHost employs a layered approach to virus scanning. While many companies install and run anti‐virus software on users' desktops and gateway servers, the fast‐moving nature of viruses today requires a more rapid response than these solutions can deliver. Leveraging XcellHost's collective intelligence across the Internet, we can frequently detect and protect from new virus deployment hours before the public can be made aware of them. XcellHost canprovide immediate protection prior to the release of anti‐virus engine updates by using its powerful policy and attribute blocking capability to block specific kinds of attachments or filter e‐mail based on specific characteristics of a message.

Outbound Scanning

In addition to securing inbound e‐mail for viruses, the  XcellHost E‐mail Security Service can also scan outbound e‐mail to protect the companies whom you communicate with. Outbound scanning gives businesses the additional assurance of protecting its extended companies including customers, partners, and suppliers from potential threat of infection from e‐mail‐borne viruses.
