Webiness Anti-Spam Service Details
Powerful, Complete Solution
The Barracuda Spam Firewall is used by small organizations with as few as 10 employees and large organizations with as many as 200,000 employees. A single Barracuda Spam Firewall handles up to 25,000 active email users and 15 million email messages per day. Multiple units can be clustered together for even greater capacity and high availability.
The Barracuda Spam Firewall protects our email server with ten defense layers:
- Denial of service and security protection
- IP block list
- Rate control
- Virus check with archive decompression
- Barracuda virus check
- User-specified rules
- Spam fingerprint check
- Intention 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 off-loading 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.
