What is Cisco Umbrella?

Cisco Umbrella uses protective DNS to provide a cloud driven Secure Internet Gateway that protects a computer from Internet based threats, wherever it is used.  Cisco Umbrella uses the internet’s DNS infrastructure to block malicious destinations before a connection is ever established.

Umbrella’s global network processes billions of requests per day.  Using big data analytics and machine learning to analyse and learn from internet patterns, Umbrella automates protection by identifying and blocking malicious domains, IPs, and URLs before they are even used in attacks.

The proof is in the numbers

200 billion daily internet requests
100 million daily users
20,000+ business clients
30+ datacentres worldwide
3 million+ new domain names discovered daily
7 million+ malicious destinations enforced concurrently at the DNS-layer

Research from AV-TEST named Cisco Umbrella the industry leader in security efficacy

How Umbrella works

Picture
DNS & IP Layer Enforcement
Umbrella uses DNS to stop threats over all ports and protocols — even direct-to-IP connections. Stop malware before it reaches your endpoints or network.

Intelligent Proxy
Instead of proxying all web traffic, Umbrella routes requests to risky domains for deeper URL and file inspection. Effectively protecting without delay or performance impact.
​
Command & Control Callback Blocking
Even if a computer gets infected, Umbrella will still prevent connections to the attacker’s command and control servers. This effectively stops data exfiltration and execution of ransomware encryption.
 

What is protective DNS?

The Domain Name System (DNS) is a foundational component of the internet — mapping domain names to IP addresses.  When you click a link or type an address (URL) in your browser, a DNS request initiates the process of making a connection to the internet. 

With protective DNS, whenever a DNS request is made, there is an intelligent process to determine if the request is safe or potentially malicious. Safe requests are routed as usual and malicious requests are blocked.

Protective DNS is recognised by leading government cyber security bodies around the world as a being one of the most effective forms of cyber security.

UK - NCSC protective DNS mandated for use by central government departments
UK - NCSC protective DNS adopted by NHS
USA - National Security Agency (NSA) pilots protective DNS
Australia - ACSC prepares to build protective DNS for government
