    OpenDNS is the world’s largest Internet-wide security network. Founded in 2005, the company has evolved from a provider of fast, reliable DNS services into a leading network and mobile security innovator that protects more than two percent of the Internet’s active users every day.

    In 2012, OpenDNS launched Umbrella, a new line of cloud-delivered security services that extend the protection of core network security infrastructure to nomadic workers that roam on and off the corporate network. Umbrella delivers a secure connection from any device, preventing contact with malware, phishing, botnets and advanced attacks, regardless of application, protocol or port.

    Unlike Web filtering, firewall and Web gateway appliances and software, Umbrella is built for today’s world of ubiquitous connectivity. It is easy to deploy and manage, with no hardware to install or software maintain, no need to reconfigure networks and no new latency. Taking advantage of OpenDNS’s predictive intelligence, Umbrella uses machine learning to automate protection against threats before an organization is attacked.
