Spam, malicious email and virus attacks are becoming ever more sophisticated. Your corporate email is a gateway that can allow sensitive information to be destroyed or lost as well as for attacks that can hurt your network performance and employee productivity. The Barracuda Spam Firewall scans email and incoming files using three layers of powerful virus scanning technology. The firewall connects to the Barracuda Security Cloud to for the most up-to-date protection against the latest email-borne threats. Threats do not always come from the outside. The firewall also checks for internally tainted email to prevent the spread of viruses that don’t access the email gateway. Barracuda is the industry leader in spam protection for businesses. The Barracuda Spam Firewall leverages Barracuda Central to identify email from known spammers and determine whether domains embedded within emails lead to known spam or malware sites.
