Cisco Buying Online Security Firm OpenDNS for $635 Million Cash

Cisco plans to buy OpenDNS, a San Francisco-based Internet security company, for $635 million in cash, assumed equity and retention-based incentives, to "add broad visibility and threat intelligence," Cisco said in a news release Tuesday. The purchase was spurred by Cisco's desire to "reduce the time to detect and respond to threats, and mitigate risk of a security breach" by combining its security capabilities with OpenDNS' "broad visibility, unique predictive threat intelligence and cloud platform," Cisco said. The buyer said it expects to complete the deal in Q1.
