A firewall is a protective system that lies, in essence, between your computer network and the Internet. When used correctly, a firewall prevents unauthorized use and access to your network. The job of a firewall is to carefully analyze data entering and exiting the network based on your configuration. It ignores information that comes from an unsecured, unknown or suspicious locations. A firewall plays an important role on any network as it provides a protective barrier against most forms of attack coming from the outside world.
Hardware-based firewalls protect all the computers on your network. A hardware-based firewall is easier to maintain and administer than individual software firewalls.
The ideal solution for small businesses is a hardware firewall integrated into a comprehensive security solution. In addition to a firewall, the solution should include virtual private network (VPN) support, antivirus, antispam, antispyware, content filtering, and other security technologies.
Look for an easy to use security solution that’s designed for small businesses and can grow with your security needs.
