Key features of GFI MailSecurity
Virus checking using multiple virus engines
GFI MailSecurity scans email for viruses using multiple 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 McAfee and Kaspersky virus engines. Multiple virus engines give you a higher level of security since virus engines complement each other and lower the average virus response time. GFI MailSecurity also includes an auto-update facility which allows you to configure the 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 an email is quarantined, it can be reviewed by the administrator who can 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 Executable Scanner
GFI MailSecurity is able to analyze incoming executables and rate the risk-level of an executable, through its Trojan Executable Scanner. This way, potentially dangerous and unknown Trojans can be detected before they enter your network.
Automated removal of HTML scripts
The advent of HTML email has made it possible for hackers/virus writers to trigger commands by embedding them in HTML mail. GFI MailSecurity checks for script code in the email message body and removes these commands before sending the "cleaned" HTML mail to the recipient. GFI MailSecurity is the only product to protect you from potentially malicious HTML email using a GFI patented process, safeguarding you from 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 perform checks for 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 which exceed the specified file amount or file size.
