Spam Mitigation
Barracuda Spam Firewall
The Barracuda Spam Firewall is an integrated hardware and software solution for complete protection of your email server. It provides a powerful, easy-to-use and affordable solution to eliminating spam and viruses from your organization by providing the following protection:
- Anti-spam
- Anti-virus
- Anti-spoofing
- Anti-phishing
- Anti-spyware (Attachments)
- Denial of Service
The Barracuda Spam Firewall is compatible with all email servers and can fit into nearly any corporate or small business environment. A single Barracuda Spam Firewall handles up to 100,000 active email users. Multiple units can be clustered together for even greater capacity and high availability.
The Barracuda Spam Firewall protects your email server with twelve defense layers:
- Network Denial of Service Protection
- Rate Control
- IP Reputation Analysis
- Sender Authentication
- Recipient Verification
- Virus Scanning
- Policy (User-specified rules)
- Spam Fingerprint Check
- Intent Analysis
- Image Analysis
- Bayesian Analysis
- Rule-based Scoring
The Barracuda Spam Firewall architecture optimizes the processing of each email to maximize performance and process millions of messages per day. Unlike software solutions, the Barracuda Spam Firewall reduces the load placed on the email server by offloading both spam and virus filtering.
In addition, all Barracuda Spam Firewall models include essential outbound filtering techniques including attachment scanning, virus filtering, rate controls and encryption. These features help organizations to ensure that all outgoing email is legitimate and virus-free.
