Our verdict on Link11 Network DDoS Protection
Link11 Network DDoS Protection is a cloud-based, fully managed service for organizations protecting business-critical infrastructure, APIs, network devices, and networks in regulated or critical sectors. It focuses on volumetric and protocol-based attacks at Layers 3 and 4, with IPv4 and IPv6 coverage, always-on mitigation, and support from Link11’s security team. The service is a strong fit for teams that want managed network protection rather than an independently operated DDoS mitigation stack.
The published plan is Network DDoS Protection, with Layer 3/4 coverage, unlimited attack mitigations, always-on mitigation, IPv4 and IPv6 coverage, and a flexible support model. Pricing uses a contact-sales model, so buyers should expect a sales-led evaluation rather than a self-serve purchase. Its standout capability is adaptive traffic analysis: AI-based mitigation, automatic threshold learning, packet-level and granular filtering, and sub-three-second mitigation on unknown vectors are designed to address changing attack patterns while limiting mitigation decisions to relevant traffic.
Operational transparency is another useful strength. Real-time transparency logs and reason codes explain mitigation actions, giving security teams visibility into how traffic is handled. The narrow network-layer focus also defines the product’s boundary: WAF protection is not included, so organizations seeking a broader application-security service should consider another option or a complementary product. Choose Link11 when always-on, managed Layer 3/4 protection and IPv4/IPv6 coverage are priorities; look elsewhere when self-service pricing or built-in web application protection matters more.
