NETSCOUT (NASDAQ: NTCT) announced enhancements to its Arbor Edge Defense (AED) solution aimed at protecting revenue-generating and mission-critical applications from sophisticated DDoS attacks that evade or bypass content delivery network (CDN) defenses. The upgraded AED restores source-level visibility for traffic routed through shared CDN infrastructure.
According to NETSCOUT, AED now uses a high-performance TLS transparent proxy to decrypt and inspect application traffic, identify true sources from application headers, and apply service-specific, application-layer DDoS countermeasures. This is designed to block malicious traffic precisely while preserving legitimate customer access and complementing existing CDN investments.

The ADP extension, integrated with Arbor Sightline and Arbor Threat Mitigation System (TMS), uses AI/ML-powered detection, dynamic mitigation, and NETSCOUT’s ATLAS Intelligence Feed and ASERT analysts. According to NETSCOUT, it leverages real-time visibility into approximately half of global internet traffic to identify and suppress attacks at their source.
