One device to firewall the network. One for antispam. Another to keep malware out. One more to filter Web content. Physical hookups, licenses, service, and support for all—what a mess.

These are essentially firewalls running additional security services, such as intrusion prevention, anti-malware, antispam, and Web content filtering. Devices like this make a lot of sense for small businesses, as they provide a single management interface. Implementation means connecting just a single device to the network, and network administrators have only one vendor to deal with.
