NETSCOUT Arbor Cloud DDoS Protection Services vs Fastly DDoS Protection: 2026 Comparison

NETSCOUT Arbor Cloud DDoS Protection Services

Mid-market and enterprise security teams expecting sub-60-second mitigation during active attacks should prioritize NETSCOUT Arbor Cloud DDoS Protection Services, where the hybrid deployment model keeps your on-premise traffic off the public internet while still routing under attack. The 16 global scrubbing centers with 15 Tbps capacity and sub-60-second SLA are backed by actual ATLAS threat intelligence, not generic signatures. This isn't for organizations looking to consolidate DDoS defense with their WAF or for teams that need deep application-layer visibility post-mitigation; Arbor stops the flood, but detection stops at the scrubbing center.

Fastly DDoS Protection

Teams operating high-traffic APIs and web applications will get the most from Fastly DDoS Protection because its pay-for-legitimate-traffic model removes the financial penalty for false positives that tanks ROI on other DDoS services. The 497+ Tbps absorption capacity and adaptive engine handle synchronized multi-vector attacks without manual rule tuning, which matters if your ops team is already underwater. Skip this if you need post-attack forensics and recovery orchestration; Fastly prioritizes real-time mitigation over the investigation side of the incident lifecycle.
