Cisco Spam & Virus Blocker is a powerful protection against Spam, Viruses, and Email Threats. The Cisco Spam & Virus Blocker immediately stops spam coming into your business email, requires minimal management, and is backed by SenderBase services, a network database of email security threats. This dedicated antispam, antivirus, and antiphishing security appliance is an easy-to-use solution designed specifically for small businesses. Other spam security products require time-consuming manual administration to be fully effective and can't match the accuracy of the Cisco solution.
