Whalebone Immunity

# The protective DNS behind DNS4EU, for your company

DNS4EU serves Europe's public sector. Whalebone Immunity is the protective DNS it is built on, and it is the route a private company takes.

## How it works

Malware needs a domain to reach whoever is running it. That is the step your firewall and your endpoint agent are not looking at, and it is the one the resolver sees.

![](https://joindns4.eu/hubfs/dns4eu/img/icon-weak-security.svg)

Over 90%

### Of attacks have to use DNS

Domains are how an attacker and their malware talk to each other. Filtering at the resolver breaks that link, and it does it before anything is installed.

![](https://joindns4.eu/hubfs/dns4eu/img/icon-time.svg)

Under 2 hours

### From decision to a protected network

Nothing to install on end devices and nothing to maintain there. On-premises, cloud or hybrid, whichever fits the network you already run.

![](https://joindns4.eu/hubfs/dns4eu/img/icon-findings.svg)

More than half

### Of trials find traffic nobody knew about

More than half also surface passwords leaked against the company domain. You see that on your own network, in your own numbers.

## Protected in no time

> It blocked malicious websites the moment our users tried to reach them. From our experience, it would take at least another day for a traditional firewall to add it to its threat database.

Both quotes are from published Whalebone Immunity case studies, linked in full below.

## Who already runs it

Banks, manufacturers and consultancies across Europe.

Banking and finance

### Where an incident is a reportable event

Banks and insurers have to show a regulator they are dealing with threats, not just that they bought a tool. DNS gives them a record of what was blocked and when.

Critical infrastructure

### Devices that leave the building

Laptops that go home, machines that cannot take an agent, and a network that cannot stop for a rollout. Protection at the resolver covers all three.

Enterprise companies

### People in several countries at once

One policy across every office and every remote worker, without asking anyone to install anything or to remember a VPN.

## In their own words

- Financial services
  
  ### Equa bank
  
  500,000+ clients
  
  A bank is one of the most regulated businesses there is, and one of the most frequently attacked. DNS gave the security team a view they did not have before.
  
  > Compromised computers that weren't under our control, brought in by external contractors. We dealt with them as well.

  ### Adastra
  
  2,000+ employees, 4 countries
  
  A consultancy handling its clients' most sensitive data, with staff scattered across the globe and no single environment to secure.
