Firewall

What is a SonicWALL firewall?

A SonicWALL firewall is what is known as a Unified Threat Management (UTM) device. The idea behind these devices is that they sit on the perimeter of a network and combine antivirus, antispyware, intrusion prevention and content filtering to manage the ingress of threats from the most common source - the internet. It allows only authorised access to your network and prevents unauthorised access. Authorised access if defined by access rules on the firewall by the system administrator.
