What Link11 Network DDoS Protection is
Link11 Network DDoS Protection is a cloud service for mitigating volumetric attacks on network Layers 3 and 4. Its always-on system learns traffic behavior and adjusts thresholds in real time. Filtering can target IP addresses, ports, and protocols, while the listed response blocks known attack vectors instantly and mitigates unknown vectors in under three seconds. Coverage includes IPv4 and IPv6 without separate policies, with unlimited attack mitigations in the listed configuration. Security teams receive real-time logs, per-IP statistics, and reason codes describing mitigation actions. Link11 describes the service as fully managed, including proactive monitoring and response, with expert support available 24/7. It is intended to protect bandwidth, network devices, APIs, web applications, and critical infrastructure from overload.
