SysEleven DDoS Guard
We’ve compiled the key information about SysEleven DDoS Guard in a factsheet.
Filter protection
SysEleven DDoS Guard gives you comprehensive protection for your network and enables targeted threat mitigation. With upstream filtering up to Layer 4, harmful data packets are filtered out early, well before they reach your network.
DNS floods
DNS flood attacks disrupt DNS resolution. This leads to reduced performance or even unavailability of your website, API, or application.
UDP floods
Attackers exploit the functions of open DNS or NTP resolvers to overwhelm a target server or network. They do this with amplified request traffic where the payload is larger than the original request.
HTTP floods
HTTP flood attacks generate large volumes of HTTP requests (e.g., GET or POST requests) from various sources. They target the application layer and result in a degradation of service quality or even a complete service outage.
Use cases
When critical infrastructure (KRITIS) fails or is disrupted, this can impact public life or the safety and health of the general public. DDoS attacks could disrupt essential services significantly. Therefore we place the highest priority on protecting this infrastructure to ensure security of supply.
Protection Against Traffic Spikes: Websites offering various products and services use DDoS Protection to safeguard their sites during periods of high traffic. By deploying DDoS Guard, legitimate user requests are distinguished from malicious traffic, enabling organizations to handle high traffic spikes without experiencing outages or delays
For SaaS providers, DDoS protection is essential to make sure that their services stay available constantly and customers stay satisfied. The consequences of a DDoS attack can range from loss of revenue to penalties for failing to meet SLAs – even losing customer trust.
Pricing
Free: All incoming traffic is scanned for suspicious activity. As soon as an attack is detected, countermeasures are automatically taken. This protection is automatically enabled for every customer at no cost. The capacity of this protection is not guaranteed on a per-customer basis, as bandwidth is shared among all customers.

FAQs
SysEleven DDoS Guard is designed to provide the best possible conditions for cost-effective and rapid mitigation in advance of DDoS attacks. We strongly recommend not waiting until an attack occurs. However, prompt deployment is possible, though it cannot offer the same level of protection as a defense that has been carefully planned in advance. We can also only guarantee the bandwidth of the traffic to be filtered up to the originally subscribed amount.
