Email security is a significant burden to firms and their technical staff.  Properly securing email servers requires highly technical skills, expensive software to filter email-borne threats like viruses and spam, and significant hardware overhead in server processor, memory, and disk space utilization.  These security methods also require constant and costly maintenance and updating to deal with new threats as they arise.  Spam consumes an estimated 21% of total internet bandwidth1, wasting a significant portion of your company’s costly internet connection. 

There is a better way.

Our Barracuda Spam Firewall protects your email servers with 12 defense layers:

Network Denial of Service Protection

Recipient Verification Intent Analysis
