Fastly Next-Gen WAF

The Fastly Next-Gen WAF (powered by Signal Sciences) is an industry-leading runtime application security and Web Application Firewall (WAF) platform engineered to protect web applications, microservices, and APIs against OWASP Top 10 vulnerabilities, zero-day attacks, and account takeover attempts. Abandoning the brittle, regex-based signature models of legacy WAFs that require constant rule tuning and frequently block legitimate customer traffic, Fastly Next-Gen WAF utilizes proprietary SmartParse threshold detection. SmartParse evaluates incoming HTTP requests in real time, analyzing the syntactic structure and context of the payload to accurately identify SQL injection, cross-site scripting (XSS), command injection, and remote code execution with virtually zero false positives. Because of its exceptional detection accuracy, more than 90% of Fastly customers run the solution in full automated blocking mode in production. The solution offers flexible deployment options, running seamlessly at the Fastly edge, within containerized Kubernetes clusters, as an Envoy/NGINX sidecar, or directly inside web application servers. With real-time telemetry streaming to SIEM and DevOps platforms, Fastly Next-Gen WAF delivers high-performance, developer-friendly application security that scales effortlessly across modern multi-cloud architectures.
