Hosted Filtering uses multiple antivirus engines to remove viruses from e-mail before the malware reaches corporations. Collectively, the engines offer massive virus signature libraries and strong heuristic detection to detect both known and unknown threats. Integration with Hosted Service’s e-mail security servers at the application programming interface level, help ensure fast scanning and the continuous updating of antivirus definitions.
Powered by multiple filtering engines and an around-the-clock team of anti-spam experts, Hosted Filtering virtually eliminates spam from inboxes, helping to provide bandwidth for legitimate corporate use, free precious server and storage resources, and decrease the risk of loss of sensitive information or identity theft. Captured spam is routed to the spam quarantine and can be accessed by administrators or end users at any time through an intuitive Web-based interface. An e-mail notification that lists newly quarantined spam can be configured to send to each valid e-mail address. This simplifies the end-user experience by making it simple and effective to review spam. Hosted Filtering offers the spam quarantine Web-based interface and HTML notifications in several languages.
Hosted Filtering administrators enforce policies they set up to comply with corporate policies on e-mail usage and with government regulations such as the Gramm-Leach-Bliley Act, SEC Rule 17a, NASD Rules 3010 and 3110, and the Health Insurance Portability and Accountability Act). The intuitive policy rule writer makes it easy to monitor and manage e-mail messages based on virtually any message attribute, such as originating IP, sender, recipient, message size, file attachment, or specific text in the subject or body. Wild cards and regular expressions are supported.
If the destination e-mail server becomes unavailable for any reason, Hosted Filtering helps to ensure no e-mail is lost or bounced. Hosted Filtering automatically queues e-mail for up to five days, attempting to deliver the email every 20 minutes. After the customer’s e-mail servers recover, all queued e-mail is automatically delivered in a flow-controlled fashion.
Real-Time Message Trace and Reporting
Administrators can use the powerful Message Trace tool retrieve the status of an e-mail processed by Hosted Filtering in real-time. With basic information, such as the sender, recipient, and date, administrators can retrieve information on e-mail processed within the last 30 days. If the search yields results, administrators will have access to the exact dates and times an email was processed by Hosted Filtering as well the results of the filtering (e.g., rejected, quarantined, delivered).
A comprehensive set of historical reports provide detailed statistics about customer e-mail traffic and are a valuable tool for gaining insight and into any e-mail system. Reporting on an e-mail occurs within one hour of the e-mail entering the Hosted Services network. Reports can be generated by domain or entire organization and provide filtering information on spam, viruses, policy filtering, delivered email, and the top virus or spam recipients.
