  • How does Network DDoS Protection reduce false positives?

    The technology continuously learns each customer’s real traffic patterns and automatically adapts its thresholds. This allows it to detect anomalies with high precision and apply targeted mitigation at the IP, port, and protocol level, thus keeping legitimate users online without manual tuning.  

  • What makes Net DDoS Protection more accurate?

    Network DDoS Protection evaluates multiple behavioral and protocol-based signals and combines them into adaptive mitigation decisions that reflect real-world traffic conditions. Its granular filtering approach matches the shape of the attack while preserving normal user activity.  

  • How is the Network DDoS Protection deployed?

    The solution is offered as a cloud service and is optimized for high performance and efficiency. Deployment is operationally smooth and supported step by step by step by the Link11 team.   

  • What are the main use cases for Network DDoS Protection?

    Common use cases include ensuring service availability during volumetric attacks, protecting bandwidth and network devices from overload, maintaining access to APIs and web applications during network-layer floods, and safeguarding critical infrastructure (e.g.load balancers, firewalls, and routers during high-traffic) or high-risk periods.  

  • How does Network DDoS Protection provide visibility into mitigation actions?

    The technology delivers real-time transparency through detailed logs, per-IP statistics, and reason codes. Every mitigation decision is explainable, giving SOC and NOC teams full observability and faster, forensic-ready investigations.
