GFI MailSecurity is an email content security solution for Exchange Server (and other mail servers) that uses multiple anti-virus engines, exploit detection, an HTML threats engine, and content and attachment checking to scan incoming and outgoing email for viruses, exploits and attacks.
GFI MailSecurity provides you with the power of five anti-virus engines, which guarantees a higher detection rate and faster response to new threats. Kaspersky, McAfee, Norman, BitDefender and AVG offer the most secure combination of unique individual virus scanning capabilities and will ensure you will be protected sooner against new outbreaks by the anti-virus engine with the fastest response time. GFI MailSecurity’s Trojan & Executable Scanner detects malicious executables without need for virus updates and the Email Exploit Engine and HTML Sanitizer disable email exploits & HTML scripts. The solution also allows you to monitor the quarantine folder through RSS feeds. A free 30-day trial version can be downloaded from our website!
