Cisco Umbrella (formerly OpenDNS) is a cloud-based security platform that provides the first line of defense against threats on the internet. Designed for companies and other organizations, It blocks malicious internet activity before it reaches the network or device. It uses DNS to prevent connections to harmful domains and offers web filtering, firewall controls, and visibility into cloud app usage. The system relies on real-time threat intelligence from Cisco Talos and is designed to protect users wherever they are, without requiring on-site hardware. OpenDNS became part of Cisco, with its enterprise solutions rebranded as Cisco Umbrella, while its consumer services continue under the OpenDNS name.
Cisco Umbrella provides protective recursive DNS (“DNS-layer security”) that blocks lookups to malicious domains before connections are made.
