Benefits

Smarter, easier security

The Fastly Next-Gen Web Application Firewall (WAF) takes a fundamentally different approach to application security, enabling increased protection without tuning, deployment anywhere you need, and industry-leading time-to-value.

Defeat advanced threats

Get protection that goes beyond OWASP Top 10 injection-style web attacks. Gain coverage against advanced threats, including account takeover (ATO) via credential stuffing, malicious bots, API abuse, and more — all in one solution.

Visibility for faster remediation

Reporting and alerting feedback loops provide Layer 7 visibility across your entire app and API footprint. Integrations with your DevOps and security toolchains encourage the sharing and correlation of data and help simplify automation, both decreasing security risks and speeding up CI/CD.

Protection everywhere your apps operate

Fastly offers the most flexibly deployed WAF on the market and can protect your apps and APIs wherever they are with one integrated solution offering the same level of visibility and actionable insights and alerts.

Features

What sets Fastly apart

Traditional WAFs rely on regex pattern-matching rules that are difficult to manage and require constant tuning to avoid false positives that block legitimate traffic. Fastly’s Next-Gen WAF effectively detects and blocks malicious traffic without tuning, so your AppSec teams can focus on bigger problems.

Contextual detection

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.

Preemptive security

NLX is a trusted IP reputation feed based on anonymized, confirmed malicious activity collected from tens of thousands of our customers’ distributed software agents. It uniquely recognizes attack patterns across our customer network, then alerts upon and preemptively defends your web apps and APIs.

Flexible Deployment

Designed for maximum deployment flexibility, our hybrid SaaS WAF installs via an agent-module software pair or via edge or cloud-based options that require no software installation. Unlike traditional web application firewalls, our next-gen WAF deploys quickly, in hours — not weeks or months — so you’re protected faster.

Threat Coverage

The modern WAAP solution

Fastly’s industry-leading web application and API protection (WAAP) solution provides real-time visibility and highly effective security for:

OWASP Top 10

Protect against both classic OWASP Top 10 attacks and advanced web attacks.

API Protection

Stop API abuse by monitoring for unexpected values and parameters submitted by endpoints and blocking unauthorized requests. Fastly can detect and block attacks in SOAP, REST, gRPC, WebSockets, and GraphQL APIs. Learn more about our GraphQL Inspection.

Bot Protection

Prevent bad bots from performing malicious actions against your websites and APIs by identifying and mitigating them before they can negatively impact your bottom line or your user experience.

Account Takeover

Block account takeover (ATO) attacks by inspecting web requests and correlating anomalous activity with malicious intent.

DDoS

Prevent malicious automated traffic that aims to overwhelm or abuse your apps so they are unavailable. When defined traffic thresholds for key application functions are met we automatically block the abusive traffic.

Rate Limiting

Stop malicious and anomalous high-volume web requests, reduce web server and API utilization, and let legitimate traffic through to application and API endpoints with our advanced rate limiting features.
