Protection Against Email-borne Threats
|
The Barracuda Spam Firewall provides comprehensive protection against the most current email-borne threats that can cripple your network if left unprotected. With a proprietary ten-layer defense system, the Barracuda Spam Firewall optimizes performance of your email server while utilizing the following protections:
- Anti-spam The algorithms and methods used by the Barracuda Spam Firewall are the most comprehensive and most advanced in the industry at detecting and filtering spam resulting with the lowest rate of false positives.
- Anti-virus By utilizing dual layer virus blocking, decompression of archives and file type blocking, the anti-virus engine in the Barracuda Spam Firewall provides complete virus protection.
- 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.
- 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.
- Anti-spyware (attachments only) - All attachments are scanned and any spyware executables are detected and eliminated immediately.
- Denial of Service Protection Rate controls are utilized to stop denial of service attacks as well as dictionary based spam attacks. These rate control systems are integrated and automatic in the Barracuda Spam Firewall.
