AWS Shield vs NETSCOUT Arbor Cloud DDoS Protection Services: Side-by-Side Comparison (2026)

Short answer

Teams already deep in AWS who need Layer 3/4 DDoS protection without adding vendors should start with AWS Shield Standard, which covers all customers automatically at no cost. The free tier blocks the majority of common volumetric attacks; Shield Advanced adds behavioral analysis and AWS WAF integration for $3,000 annually, meaningful only if you're absorbing sustained multi-Gbps floods regularly. This is not a replacement for application-layer DDoS mitigation or a choice for organizations running multi-cloud infrastructure where you need consistency across providers. 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.
