The Barracuda Spam & Virus Firewall is an integrated hardware and software solution designed to protect email servers from spam, virus, spoofing, phishing and spyware attacks. It leverages 12 comprehensive defense layers to provide industry-leading defense capabilities for any email server within large corporate or small business environments. It is compatible with all email servers.
Barracuda is one of the leading and most widely used spam filtering appliance. It eliminates spam and virus intrusions while safeguarding an organization’s reputation through content inspection based on policy for both inbound and outbound email. Outbound filtering also prevents confidential or sensitive information from being purposely or inadvertently leaked outside the organization.
The standard deployment configuration of the Barracuda Spam Firewall consists of a single email server and a single Spam Firewall appliance. Simply connect the Barracuda Spam Firewall to your network by assigning it a new IP address and changing your MX record to point to the Barracuda Spam Firewall (see figure below). Alternatively, you may also give your email server a new IP address and give the old IP address to the Barracuda Spam Firewall. Other configurations include one Barracuda unit and multiple email servers and multiple domains. For automatic scalability, redundancy and fault tolerance, you may cluster multiple Barracuda Spam Firewalls.
