Founded in 2006, OpenDNS, now part of Cisco, has evolved from a provider of fast, reliable DNS services used by more than 65 million active users every day into a leading network security innovator. 

In 2012, we launched our first enterprise security product, Umbrella. Today, Cisco Umbrella is a cloud security platform that provides the first line of defense against threats on the internet wherever users go. By learning from internet activity patterns, Umbrella automatically uncovers current and emerging threats. And because it’s built into the foundation of the internet and delivered from the cloud, Umbrella is the simplest security product to deploy and delivers powerful, effective protection.
