Knowledge Base

The Sophos Email Appliance is a specialized server that is used at the gateway to scan email for viruses and spam. Email is scanned before it enters your network, and any unwanted or suspicious items can be removed before messages reach your mail server.

You can also use the appliance to scan outgoing email for viruses and spam, prevent the accidental loss of sensitive information with Data Loss Prevention (DLP), and protect sensitive data with Secure PDF Exchange (SPX).

The appliance plugs directly into your network. It provides a management console that you access from another computer, using a web browser.

The Sophos scanning software is already installed and configured on the appliance when you buy it. You can either accept the default settings or customize the configuration if required.

Online help becomes available when you power on the Appliance.
