Advanced threat protection using DNS
Cisco OpenDNS uses a novel approach to protecting your network from threats. Every time your computer goes online it uses DNS to turn web addresses into IP addresses. Much like the white pages used to provide a phone number based on a name, DNS servers allow your computer to find what it is looking for online. By using Cisco OpenDNS as your DNS server(s) you allow them to block access to sites that are a threat to your computer. Additionally, they categorize sites based on content and optionally give you the choice to restrict access to sites that are not appropriate in a business environment.
