About the Fastly Next-Gen WAF

Fastly Next-Gen WAF, powered by the former Signal Sciences technology, is a cloud-delivered Web Application and API Protection (WAAP) solution designed to defend against modern web exploits, API attacks, and automated threats (bots) without impacting performance. Unlike traditional WAFs that rely heavily on static rules and regex, Fastly's patented SmartParse engine analyzes requests based on context and behavior, significantly reducing false positives and enabling customers to operate in full blocking mode. It offers a unique module-agent architecture, where lightweight agents are deployed directly on the customer's infrastructure (web servers, application servers, containers, PaaS) to detect and block threats at the application layer, while asynchronously sending metadata to a cloud-based analytics engine for deeper insights and adaptive threat intelligence. It provides comprehensive visibility into attacks, detailed event logging, and seamless integrations with DevOps tools for automated security workflows and rapid incident response. It is known for its ability to protect high-volume, complex applications and APIs across various environments (on-premises, cloud, hybrid).
