DNS Security - your first line of defence

Cybercriminals use email or websites to steal confidential data (phishing), to spread and install malicious files (malware), and then to manipulate compromised computers (via command and control callbacks). Business DNS Security knows which addresses are dangerous and automatically blocks Internet connections that could harm your company.

Before the browser can load dangerous web content or download and install malicious files, the query is blocked and a warning is displayed. This cloud service operates as a first and very effective line of defence on the DNS level and supplements existing classic security solutions such as firewalls, virus protection and VPN.

Business DNS Security works with all types of Internet access services of Sunrise with fix IP. 

Business DNS Security will be automatically activated by Sunrise UPC for your network after you purchase the service and will protect your LAN/WLAN. You don’t need any additional hardware.

You will be able to define your own security policies on the DNS Security (Umbrella) Dashboard accessed via mybusiness portal (a proven set of standard policies is pre-defined by Sunrise). You'll also be able to download the Roaming Client Software for Windows or macOS, which you can install on devices which are leaving your LAN/WLAN environment to benefit from DNS Security while on the go. 

Via the Dashboard you will be able to monitor your Internet activity, the status of your Business DNS Security service and other relevant security information. When the Roaming Client software (Software to ensure security features outside of the protected LAN / WLAN environment) is installed, you can see the status directly in the toolbar or menu bar of your PC or Mac. 

Business DNS Security uses the cloud security services from Cisco Umbrella. You benefit from the world's leading Internet security research and analysis team, the Cisco Talos Intelligence Group, without having to setup complex configurations or installations yourself. Business DNS Security will be activated by Sunrise and your LAN/WLAN will be protected automatically. For employees outside the LAN / WLAN environment you install a simple and lightweight Roaming Client software for macOS or Windows for immediate protection at home or on the go. The intelligent DNS security identifies harmful domains, IPs and URLs and blocks them before they have a chance to attack your systems and/or network. Business DNS Security thus offers efficient protection against phishing and malware attacks regardless of your location.

The Domain Name System is a fundamental component of the Internet which links a domain name with the associated IP address. When you click on a link or enter an URL in the browser (such as, the DNS query initiates the process of connecting the respective device to the correct server.
