More About Link11
Link11 focuses on protecting the availability and performance of digital services through cloud-based security offerings centered on DDoS mitigation (network and application security). Its services are designed for enterprises, online businesses, critical infrastructure operators, and service providers that rely on continuous uptime of websites, APIs, DNS, and networked applications. Link11 operates scrubbing infrastructures that inspect and filter traffic before it reaches customer environments, aiming to block volumetric, protocol, and application-layer attacks while allowing legitimate traffic.
The company’s core offerings map to categories such as network DDoS protection (network security), web and application DDoS protection (application security), and managed availability services (managed security services). Customers typically connect to Link11 via Border Gateway Protocol (BGP) rerouting, DNS redirection, or integration with upstream carriers and hosting providers. In a BGP-based architecture, attack traffic is rerouted to Link11’s scrubbing centers where traffic is analyzed and cleaned using rule-based filters, heuristics, and automated detection algorithms before being forwarded to the protected network. For web and application workloads, Link11 can be positioned in front of origin servers through DNS-based redirection, functioning as a protective layer for HTTP/HTTPS and related protocols.
From a technology perspective, Link11’s platform is associated with automated traffic analysis, anomaly detection, and multi-layer filtering techniques across network (L3/L4) and application (L7) layers. The services are designed to work with common internet protocols including Transmission Control Protocol (TCP), User Datagram Protocol (UDP), HTTP/S, and DNS. Enterprises often integrate Link11 into existing network edge architectures that include firewalls, load balancers, and content delivery infrastructures. The goal is to provide an additional external shield that absorbs and filters malicious traffic upstream so internal security and network components remain operational under load.
In the enterprise and service-provider marketplace, Link11 is categorized within cloud-delivered DDoS mitigation (network and application security) and availability-focused Managed Security Services (MSS). It is used by organizations that need SLA-backed protection for online revenue channels, customer portals, and latency-sensitive digital services. Carriers and hosting providers can use Link11 to offer white-label or integrated protection services to their downstream customers, inserting Link11’s scrubbing and mitigation capabilities into their own connectivity or hosting portfolios. For directory and taxonomy purposes, Link11 aligns with categories such as DDoS protection, network traffic scrubbing, application-layer attack mitigation, and managed SecOps for availability and uptime.
