SPAM > Protection Against Email-borne Threats

MailScrub uses the Barracuda Spam Firewall which provides comprehensive protection against the most current email-borne threats that can cripple your network if left unprotected. With its proprietary twelve-layer defense system, the Barracuda Spam Firewall optimizes performance of your email server while utilizing the following protections:

Spam Filter Anti-spam.  Barracuda Networks Predictive Sender Profiling looks beyond the reputation of the sender and digs deeper into the spam campaign itself to identify anomalous activity.
Spam Filter Anti-virus.  By utilizing triple layer virus blocking, decompression of archives and file type blocking, the anti-virus engine in the Barracuda Spam Firewall provides complete virus protection. When new spam and virus outbreaks occur, Barracuda real-time protection will block these threats immediately.
Spam Filter Anti-spoofing.  This technology prevents the use of forged or "spoofed" sender addresses on unsolicited email. The anti-spoofing feature also allows larger organizations to specify a list of IP addresses that are allowed to have a "From" address that appears from inside the organization to support multiple sites and multiple email servers.
Spam Filter Anti-phishing.  The Barracuda Spam Firewall provides robust protection against phishing schemes which are often used to gather confidential information about an organization or its individual users.
Spam Filter Anti-spyware.  (Attachments) - All attachments are scanned and any spyware executables are detected and eliminated immediately.
Spam Filter Denial of Service Protection.  Rate controls are utilized to stop denial of service attacks as well as dictionary based spam attacks.
