Reduce Cloud Spend
Stop attacks from hitting your origin and inflating operational costs while creating reduced, more consistent cloud spend overall.
Features
Every app and API needs DDoS protection
From startups launching their first mobile app to the world’s largest e-commerce sites, every application and API on the internet is susceptible to DDoS attacks slowing their service, inflating cloud expenses, or, worse, taking them offline. With Fastly DDoS Protection, anyone can flip a switch and gain immediate protection.
-
Scalable network
Building on our powerful, global network offering 497+ Tbps as of September 30, 2025, we automatically absorb massive network layer attacks while dropping any irrelevant non-HTTP/HTTPS traffic. With the power of Fastly’s platform, we dynamically and proactively process, analyze, diagnose, and respond to DDoS attacks of all sizes so your team can uphold scalability, stability, and reliability – all with one click of a button.
-
Automatic mitigation
Enable Fastly DDoS Protection with the flip of a switch to automatically block application DDoS attacks – from everyday nuisances through never-before-seen traffic spikes – to ensure they don’t disrupt your business. When unexpected volumetric traffic events arise, Fastly’s proprietary Adaptive Threat Engine validates their legitimacy and if malicious, begins scanning a comprehensive list of characteristics to isolate and mitigate the attacks, even if they rotate IPs.
-
Versatile protection
No matter your architecture, you can deploy Fastly’s DDoS Protection to gain speedy, scalable defenses without tuning, even as you ship changes on-demand. It mitigates application DDoS attacks before they turn into incidents, without forcing engineering teams to become security experts or purchase confusing bundles. Start with dynamic, proactive protection at the click of a button, then integrate with the rest of our edge cloud platform when you’re ready.
