OpenDNS provides a secure DNS offering with advanced threat protection for “any device, across any port, protocol or app.” Its predictive security model is designed to anticipate malicious activity, including botnets and phishing. Its DNSCrypt technology converts regular DNS traffic into encrypted DNS traffic to prevent eavesdropping and man-in-the-middle attacks. The service is hosted in peering data centers around the world.
Cisco said the acquisition will boost its Security Everywhere approach by adding broad visibility and threat intelligence from the OpenDNS cloud delivered platform.

- OpenDNS was founded in 2006 by David Ulevitch. Investors included Sutter Hill Ventures, Greylock Partners, and Sequoia Partners.
