Arbor Networks

Arbor Networks (acquired by Netscout) is the absolute, unquestioned, terrifyingly entrenched grandfather of the "Carrier-Grade DDoS" market. If you are a Tier 1 Global Internet Backbone Provider (like AT&T or Verizon), you do not use cloud proxies. You use Arbor. Arbor is mathematically engineered into the absolute core fabric of the global internet, providing the foundational mathematical visibility required to keep the internet physically functioning during nation-state cyber warfare. Its signature feature is "The ATLAS Global Threat Intelligence System." Because Arbor is deployed inside 90% of the world's Tier 1 ISPs, it mathematically sees roughly 30% of all internet traffic on Earth. Arbor mathematically anonymizes and aggregates this data into ATLAS. If a massive new IoT botnet boots up in China, ATLAS mathematically detects the anomaly across the global backbone instantly, and automatically pushes the mathematical countermeasures to every Arbor deployment globally. It heavily dominates "Sightline (Formerly Peakflow) Architecture." Arbor Sightline mathematically ingests NetFlow data directly from the ISP's massive core routers. It mathematically profiles the entire country's traffic. When an attack occurs, Sightline mathematically detects it, calculates the exact BGP Flowspec mitigation rule, and automatically programs the core routers to drop the traffic, neutralizing 500 Gbps attacks entirely on-premise without ever sending traffic to a cloud scrubbing center.
