Overview

Cisco Umbrella delivers cloud-based enterprise security that protects networks, users, and devices from cyber threats. Its core products—DNS-layer security, secure web gateways, and cloud-delivered firewall—work by routing traffic through a cloud security stack where DNS queries are filtered, web traffic is inspected, and firewall policies are applied from the cloud. It differentiates itself with a DNS-first, cloud-native approach and tight integration within Cisco’s security ecosystem, providing centralized visibility for large organizations, schools, and government agencies. The goal is to simplify and strengthen enterprise network security by delivering scalable, cloud-based protection that reduces exposure to malware, phishing, and other online threats.
