OpenDNS makes the Internet experience safer, faster and smarter for you and everyone using your network. OpenDNS can identify and stop sites trying to phish (steal) your personal information or money. The OpenDNS phishing protection works with all operating systems and browsers, and complements any other security measures already in use, such as a firewall and anti-virus software. Most DNS servers on the Internet are slow. Your computer uses DNS every time you visit a website or send an email, so you want DNS to be blazing fast. Two things make DNS really fast: a big cache and a good network. OpenDNS has both.
