Cisco Umbrella

Cisco Umbrella, formerly known as OpenDNS, provides the first line of defence against threats on the internet by blocking requests to malicious internet destinations (Domains, IPs, URLs) using the Domain Name System (DNS) before an IP connection is established.

The service is cloud delivered with no hardware to install or software to be maintained.

The Umbrella network contains 30 data centres around the world using Anycast DNS which allows for 100% uptime.

Anycast means that a DNS request is always routed to the closest destination.

Intelligence is gathered from the 175 billion daily DNS requests into Umbrellas database.

Umbrellas database analyses statistics and makes use of machine learning to check the safety of domains, along with Umbrella security researchers and information supplemented by Cisco Talos.

Using Umbrella in a corporate network just invovles using Cisco Umbrellas DNS servers.

Cisco AnyConnect VPN client can redirect any roaming corporate devices to utilise Cisco Umbrellas DNS servers even when the VPN is turned off.

There is the availability of the Cisco Umbrella roaming client instead of the Cisco AnyConnect VPN client that provides the same DNS filtering functionality.
