Next-Generation Web Application Firewall (WAF)

The Signal Sciences NGWAF module provides flexible, scalable, and accurate protection for modern web applications by embedding directly into the web server itself.


Most Signal Sciences customers deploy the web protection platform as a NGWAF module directly into the web server instance. It’s easy to install into the most common and frequently used web application servers (such as NGINX, Apache, and IIS) and uses a safe, fail-open architecture to communicate with the Signal Sciences local agent. This allows for a fast, reliable, and secure asynchronous connection to the Signal Sciences cloud decision engine, ensuring that your customer traffic remains stable—no matter what.

Benefit 1

Minutes to Install

Because Signal Sciences provides easy installation packages and configuration management scripts, the NGWAF module is a frictionless install for most deployments. With a simple one-line configuration change, your security is up and running in minutes, providing your web applications, microservices, and APIs instant protection and visibility.

"Dropping in Signal Sciences was trivial and was so easy from an operations perspective!"

Benefit 2

Extremely High Performance

The Signal Sciences NGWAF module was designed from scratch to be compact, highly performant, and to provide the lowest latency for data passing to the Signal Sciences cloud decision engine. In other words—it’s fast. So fast, in fact, that Signal Sciences is used by extremely performance sensitive customers, including several of the world’s largest mobile gaming companies, precisely because of its patent-pending performance architecture.

Benefit 3

Fail-Safe Protection

The NGWAF module and agent combination are designed to work in tandem, operating as an asynchronous connection to the Signal Sciences cloud. The result is a fail-safe system that allows the decision and enforcement system to work regardless of the connection to the cloud engine. By isolating decisions from enforcement, Signal Sciences handles failures gracefully, keeping your application protected at all times.

Benefit 4

Reliable Decisions

Because the Signal Sciences WPP considers data points well beyond basic indicators, it makes exceptionally accurate decisions with a high level of confidence. The WPP looks at individual signals and how they group together into tech patterns over time. We don’t alert on any one signal, because a typical attack isn’t one request—the WPP looks at how individual signals group together and alerts on those attack patterns happening over a period of time, providing you with next-level protection.

Benefit 5

Exceptional Scalability

The Signal Sciences NGWAF module takes scalability to truly unparalleled levels by embedding directly into every application instance in your environment. As you scale your infrastructure, Signal Sciences scales with you. Our web protection platform handles spikes in traffic, business growth, and rapid infrastructure changes—there are no VMs to resize or larger appliances to deploy. Signal Sciences keeps pace naturally and automatically without any additional capacity planning overhead.
