Antispam Filtering: The End of Junk Email

Antispam filtering helps keep your business from being inundated with irritating, time-consuming, and sometimes dangerous junk email. The following is a brief guide to understanding what antispam filtering does, the differences between software-only and hardware solutions, and what to look for in an antispam filtering appliance.

Antispam Filtering - What It Does

Antispam filtering is an essential component of any network security toolkit. It prevents unwanted email from overwhelming employee inboxes. Antispam solutions can also protect against the latest viruses, phishing attacks, and other threats that arrive through email.

The Differences Between Antispam Software and Hardware

Antispam filtering falls into two categories: software-only products and dedicated hardware appliances (which use their own internal software).

To be effective, an antispam software-only product must be installed, maintained, and continuously updated on each computer it protects. However, this can become expensive and cumbersome to manage, and can also slow down the computer. Also, if one computer's antispam protection lapses or is breached, other computers on the network can become vulnerable to a fast-spreading virus or other threat.

An antispam filtering appliance is a single hardware device that simultaneously protects all computers on a network. The device sits on a network between the firewall and email server, preventing spam and other threats from reaching the email server and user inboxes. The appliance is installed, configured, and updated, using built-in software. An antispam appliance is the easiest, most effective, and most cost-efficient way to protect multiple computers on a network.

What to Look for in a Dedicated Antispam Appliance

Ideally, you should shop for an antispam appliance that:

  • Stops spam, viruses and other malware before they get to your email servers
  • Offers easy, Web browser-based installation, so it can be installed quickly and easy, and start working immediately
  • Provides protection that continually and automatically updates itself, safeguarding your business from emerging, quickly-spreading threats
  • Is purpose-built for the needs and budgets of your business
