Cisco plans to buy security-as-a-service provider OpenDNS
Cisco Systems plans to pay $635 million in cash to buy OpenDNS, a company that leverages the Domain Name System (DNS) to provide security services including Web filtering, threat intelligence and malware and phishing protection.
The DNS is a core Internet protocol. It’s used to translate Web addresses that are easy for people to remember, like website names, into numerical IP (Internet Protocol) addresses that computers need to communicate with each other.
OpenDNS customers configure their computers or networks to use the company’s DNS resolution servers instead of the ones provided by their ISPs and this allows OpenDNS to provide additional services.
