Alibaba Cloud Anti-DDoS vs Fastly DDoS Protection: Side-by-Side Comparison (2026)

Alibaba Cloud Anti-DDoS

SMB and mid-market teams in Asia-Pacific will find Alibaba Cloud Anti-DDoS worth the deployment friction because of near-source mitigation via Anycast, which drops latency-induced false negatives that plague centralized scrubbing centers. The 20+ Tbit/s capacity across global centers handles the sustained volumetric attacks that regional providers routinely fail on. If your origin infrastructure sits outside Alibaba's ecosystem or you need NIST Recover coverage beyond detection and response, the transparent deployment options become constraints rather than features.

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.
