DDoS Protection

Web apps can be easily disrupted by Distributed Denial of Service attacks, causing lengthy interruptions to transactions. DDoS Protection helps against massive attacks.

Keep your web app online at all times

Distributed-Denial-of-Service (DDoS) attacks can cause entire network infrastructures to go down if the attack is sufficiently strong. Swiss IT Security Deutschland implements DDoS protection with solutions by its partners Link11 and Corero. The interaction of the two solutions provides comprehensive protection against DDoS attacks.

Link11 offers reliable and comprehensive protection against DDoS attacks with multiple award-winning German filter technology. Customers that need the highest level of availability (e-commerce, banks, insurance companies, etc.) often already use Link11’s cloud-based protection solution, which switches between the attacker and the target server and keeps the customer server accessible to normal users. Corero’s solution provides for an appliance installed in the customer’s network. A patented DDoS defence algorithm recognises and filters malicious data traffic, but allows regular traffic to pass through. This is an effective defence against short, targeted DDoS attacks.
