Spam Blocker Technology - At a Glance

Spam blocker technology is available in two forms: as software-only products, and as dedicated spam blocker appliances. The following is a quick overview of the differences between them, plus a brief description of the Cisco Spam and Virus Blocker.

Software-Only Spam Blocker

In some businesses, spam blocker software is installed on each computer, either as a component of an Internet security suite, or as a dedicated spam blocker application or email plug-in. The software automatically identifies and blocks spam and other threats that travel through email.

Spam blocker software is usually inexpensive, or even free. But the antispam software on each computer must be maintained and continuously updated, which can be difficult to manage. The software many also slow the computer's performance.

More importantly, antispam software typically isolates spam and harmful email only after they have been transmitted to a user's computer. This can increase the chances that users will come into contact with unwanted or even risky email. When that occurs, a user may unwittingly open a virus-infected file attachment -- and spread an infection to other computers throughout the network.

Spam Blocker Appliances

A dedicated spam blocker appliance sits on a network between the firewall and email server. It identifies and blocks spam and other threats before they reach the organization's email server or computers. As a result, the business is better protected from email threats.

An antispam appliance is a single device that simultaneously protects all computers on a network. This helps reduce operational costs and security management chores.
