Why is the Barracuda better?
What separates the Barracuda device from other anti-spam techniques is Barracuda Central. This is a 24/7 security operations center that has engineers who continuously monitor the Internet for the latest spam definitions, viruses and other email-borne threats. Automatic updates are sent hourly to your Barracuda device. The updates help protect your company's security by staying ahead of the spammers as they come out with new ways of getting through your security.
The automatic update service, Energize Update, is renewed on an annual basis.

Installation
There is no software to install and only a change to your MX record to incorporate the unit into your network. The unit is compatible with all email servers and can fit into nearly any corporate or small business environment. A single unit can handle up to 30,000 active email users. Multiple units can be clustered together for even greater capacity.
The minimum install requires you to...
- Assign the unit a new unique IP address
- Provide the address of your current email server
- Connect it to your network
- Change your domain MX record to point to the new IP address
- Provide initial training of at least 200 spam vs non-spam emails

Management
You can select from a variety of statistical reports that can be automatically emailed. The unit is designed to be virtually maintenance free. You can subscribe to an optional Instant Replacement program which provides for next day replacement.
Configuration is done through a Web-based interface that is built into the system. Even though the screens and options are comprehensive and allow for a large amount of customization, customization is rarely required because the unit comes with default settings and self-tuning parameters that cover 95% of your needs.

How it Works
Each email is comprehensively evaluated using two main classes of sophisticated algorithms and techniques...
- Connection Management
- Emails are filtered through five defense layers to verify authenticity of envelope information
- Any inappropriate incoming mail connections are dropped even before receiving the message
- The majority of spam emails are caught at this point, which greatly reduces the amount of network traffic on your Internet connection
- Mail Scanning
- Any emails that survive the connection verification process must then undergo a thorough mail scanning process that involves an additional seven defense layers of message analysis.
