Fastly DDoS Protection is a commercial distributed denial of service mitigation tool by Fastly. Imperva DDoS Protection is a commercial distributed denial of service mitigation tool by Imperva. Compare features, ratings, integrations, and community reviews side by side to find the best distributed denial of service mitigation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Teams protecting APIs and web applications under sustained volumetric attack need Imperva DDoS Protection for its 3-second mitigation SLA on Layer 3 and 4 floods, which eliminates the window where traffic actually reaches your infrastructure. The 13 Tbps global scrubbing capacity and Anycast routing handle the size of attacks most vendors only claim to handle. Skip this if your DDoS concern is primarily application-layer sophistication; Imperva's Layer 7 protection exists but the real competitive edge is raw speed on the attacks that actually cause downtime.
