Why select Fastly over Imperva?
Performant Network
Fastly’s network is more performant than Imperva’s. Fastly’s 500+ Tbps vs. Imperva’s 13 Tbps equates to better customer experiences and enhanced DDoS protection.
Improved Visibility
Unlike traditional WAFs, Fastly's Next-Gen WAF also leverages Signals – clear, easy-to-understand labels attached to requests. These Signals provide deep visibility into traffic behavior, helping you quickly identify, understand, and respond to potential threats.
Deploy Anywhere
Fastly’s Next-Gen WAF rapidly deploys and protects everywhere your apps operate - containers, clouds, on-premises, at the edge, and beyond - all within a single offering.
Superior Detection
Fastly Next-Gen WAF's SmartParse detection engine is able to make highly accurate, contextual classification of attack traffic, eliminating the need for the numerous, maintenance-intensive regex rulesets required by Imperva. Fastly’s approach results in fewer false positives and less tuning toil than regex.
Shift Everywhere
Built for DevSecOps, Fastly’s API-first architecture satisfies admins and developers alike - CDN and security services effortlessly integrate into existing CI/CD workflows, yielding faster innovation and deployment cycles.
Improved TCO
Users can make their changes through an intuitive Control Panel, removing reliance on costly Professional Services and customer support. And since we do not sell appliances appliances, the saving passes to the customer.

“We deployed the Next-Gen WAF behind our current WAF, and over one weekend we saw it block attacks our WAF was missing. The dashboards allowed us to easily see and track malicious activity in a way we couldn’t with our old WAF.”
