Schedule a demoWhat sets Fastly apart
Traditional web application firewalls (WAF) rely on regular expression pattern-matching rules. They’re difficult to manage and require never-ending rules tuning to eliminate false positives that can block legitimate traffic. The Fastly Next-Gen WAF leverages a fundamentally different approach, developed by Signal Sciences, that effectively detects and blocks malicious traffic without rules tuning, leaving your AppSec teams to focus on bigger problems.
Network Learning Exchange (NLX)
NLX is a trusted IP reputation feed based on anonymized, confirmed malicious activity collected from tens of thousands of our distributed software agents. It is uniquely able to recognize attack patterns across our customer network, then proactively alert upon and defend your web apps and APIs.

SmartParse
Unlike common regex-based WAFs, our next-gen WAF uses SmartParse, a highly accurate detection method, to evaluate the context of each request and how it would execute, to determine if there are malicious or anomalous payloads in requests. SmartParse enables near-zero tuning and the ability to start detecting threats immediately.
