Network Security

Umbrella’s advanced threat protection is fueled by predictive security intelligence from OpenDNS Security Labs’ Big Data analytics.

Umbrella protects you from malware by blocking known and predicted malicious domains and IPs from resolving at the DNS layer. Unlike pure proxy solutions, Umbrella is a cloud-delivered, DNS-based security platform that proactively stops infections and attacks over any Web or non-Web port, protocol or app.

When we see a DNS request for a known or predicted botnet controller, we block the domain from resolving and notify you of which network and specific device is infected.
