Link11 Web DDoS Protection

The patent pending Link11 DDoS protection for websites is a unique piece of technology. Attacks are blocked and filtered using Artificial Intelligence so you can keep your focus on everything that keeps your business running. One of the toughest authorities worldwide - the German Federal Office for Information Security (BSI) - officially confirmed the effectiveness of the DDoS protection solution and identified Link11 as a qualified DDoS-mitigation-provider.

DDoS Protection for Webservices

Web DDoS Protection

DNS Forwarding can already be realized with one existing IP address. All you have to do is to edit the DNS A-Record entries and within a short period the whole data transfer is routed over the Link11 filter center and the DDoS Protection is immediately activated. This way, applications based on a domain name can be protected against DDoS attacks over layers 3-7 in real-time.

Intelligent Threat Detection

Fingerprint Technology

Every user leaves a digital fingerprint in the internet. This print can be created out of hundreds of traceable attributes. The Fingerprint Identification developed by Link11 analyzes the behavior of browsers and computers and creates an anonymous digital DNA that is temporarily saved for further reference within the database of the cloud protection. This assures that customers can safely reach their destination.

Powerful Protection

Self-learning AI Shield

Every attack mitigated by Link11 is saved within a sequence database. The Self-learning AI that is part of the DDoS protection analyzes every attack sequence and compares these with existing data. Every company that is connected to Link11 benefits from this technology because it is capable of reacting even faster when similar incidents occur.

Strategically placed

Global Filter Locations

A large filter network of worldwide and handpicked scrubbing locations in Frankfurt, Zurich, Amsterdam, London, Miami, Los Angeles, Singapore and soon Hong Kong, guarantees global protection, performance and availability in case of a DDoS attack. Attacks reaching bandwidths of hundreds of Gbps are no threat to the Link11 Protection Cloud.

Control and Visibility right from your Desk

Link11 WebGUI

Link11 offers its customers a web-based, graphical user interface to monitor the server functions. The interface provides insight into the real-time traffic analysis, shows blocked DDoS attacks, server availability and provides metrics on current server response times. Graphical Timelines can be displayed and analyzed as desired. In addition, the nature of the attacks and the respective places of origin are clearly presented. In addition to user management (with individual read or write rights), the WebGUI makes it possible, for example, to block entire countries with the geo-blocking function.

Diagnostic Dashboard

The Diagnostic Dashboard offers general DDoS information and hints on current threats. In addition, a DDoS warning system and DDoS traffic indicator offer a quick overview on the current security status. In the settings area, the granularity of the intelligent DDoS prevention can be set and customized blocking can be used to adjust settings for authorized and unauthorized access.

Customizable Control

The customizable control can be used to set up permanent authorized access for systems that deviate too far from that of a normal user. For example, desirable Dashboard view of the Link11 Dashboard automated scripts such as crawlers can be identified, ensuring compatibility with standard search engines, desirable advertising bots and administrators.


Our reporting makes it possible to generate individual and routine reports in a management overview. The reports can be transmitted on a regular and automatic basis. Any settings made by administrators in the user interface can be traced and edited ad hoc.

Alert Function

An alert-function is able to send SMS alerts about current threats. The prevention list states the reason for each prevented connection, the origin and the duration of the connection. The prevented connections can also be authorized to access the server on their next attempt.
