1.2 Key features of GFI MailSecurity Virus checking using multiple virus engines GFI MailSecurity scans email for viruses using multiple anti-virus engines. Scanning email at the gateway and at mail server level prevents viruses from entering and/or spreading within your network. Furthermore, you can avoid the embarrassment of sending infected emails to customers as GFI MailSecurity also checks outgoing mail for viruses. GFI MailSecurity includes the industrial strength Norman and BitDefender anti-virus engines that have received various awards. You also have the option to add the AVG, McAfee and Kaspersky anti-virus engines. Multiple anti-virus engines give you a higher level of security since anti-virus engines complement each other and lower the average response time to a virus outbreak. GFI MailSecurity also includes an auto-update facility that allows you to configure the anti-virus engines so that they automatically check and download any available updates without administrator intervention. Email attachment checking/filtering GFI MailSecurity's key feature is the ability to check all inbound and outbound email. It can quarantine all email with dangerous attachments, such as *.exe, *.vbs and other files. Such attachments are more likely to carry a virus, worm or email attack. Since email viruses can spread so quickly and cause immense damage, it is best to quarantine such emails before they are distributed to your email users. When GFI MailSecurity quarantines an email, the administrator can review it and then delete or approve the message. Furthermore, you might choose to quarantine mails carrying *.mp3 or *.mpg files, as these hog bandwidth and can needlessly burden a mail server's disk space. The Attachment Checking module has effectively saved thousands of companies from the LoveLetter virus. Trojan and Executable Scanner GFI MailSecurity is able to analyze incoming executables and rate the risk-level of an executable through a GFI patented process. Through the Trojan and Executable Scanner, GFI MailSecurity can detect and block potentially dangerous and unknown Trojans before they enter your network. HTML Sanitizer The advent of HTML email has made it possible for hackers/virus writers to trigger commands by embedding them in HTML mail. GFI MailSecurity scans the email body parts and any .htm/.html attachments for scripting code, and cleans up the HTML by removing all the scripting code. The HTML Sanitizer thus protects you from potentially malicious HTML email, containing HTML viruses and attacks launched via HTML email. Decompression filter The decompression filter is used to decompress and analyze compressed files (archives) attached to emails. This filter is able to check for and block password-protected archives, corrupted archives and recursive archives. Furthermore, this engine can also monitor the size and amount of the files included in an archive. You can configure this filter to quarantine or delete archives that exceed the specified file count or file size.
