OpenDNS is a phishing protection system that defends against identity theft.
The Internet is a magical, wonderful invention, and one that has made our world a better place. Unfortunately, there are still a few kinks to work out when it comes to our security. Fraudulent websites that masquerade as something they're not have the ability to swipe all of our essential, and most private, information, requiring us to seek out some sort of protection.
With the use of PhishTank, OpenDNS is able to "take the guesswork out of spotting  dangerous links." Even if a link manages to get by us, the system will prevent it from loading, ensuring that all of our most personal information is kept completely and totally safe.
