Patented, proven and certified

Maximum security and lightning-fast performance from a single source

Patented DDoS protection, comprehensive security for web applications and APIs as well as maximum content performance.

If you operate your own IT infrastructure yourself, extreme caution is required, as these are increasingly being targeted by attackers. A reliable protection solution is needed to effectively prevent attacks on applications and services in an autonomous system.

Network DDoS Protection
NetFlow DDoS Analyzer

Digital web applications are often hosted by external cloud providers, as no in-house infrastructure exists or shall not to be set up. These providers are often not ideally prepared for major attacks.

Web Application & API Protection (WAAP)

Fast content availability is a must today. Retrieving texts, images, videos or scripts should be guaranteed at any time and from anywhere – but without compromising security.

„When onboarding with Link11, we must emphasize that the contact and speed were very good and extremely helpful. We recommend Link11 to all companies that see a risk in their carriers being overloaded with DDoS attacks.“

Kai Widua,

CISO

„DDoS attacks are a real risk and it is out of the question for us to first allow any threats to occur and only then react. With Link11, we now have technologies for the best possible protection and at the same time no latency delays.“

Alexander Test,

IT Service Manager

„DDoS attacks are a real risk and it is out of the question for us to first allow any threats to occur and only then react. With Link11, we now have technologies that provide the best possible protection without any latency delays.“

Jochen Weper,

Produkt Manager

„The threat of a DDoS attack is real and we had to adapt and increase our protection bandwidths. Link11 has better algorithms for an optimized response in the event of an attack and is therefore much more reliable. Now we feel we are on the safe side.“
