Application, API, Bot, ATO,
and App DDoS

Web application attacks continue to be the top source of data breaches. Modern application design and deployment has changed drastically over the past decade – and legacy WAF appliances have not adapted to these changes: based on defense technology over a decade old that relies on regular expression pattern matching, legacy WAF vendors cannot keep up with the speed of modern software DevOps development and deployment.

Installs Quickly. No Rules Tuning.

Legacy WAF appliances cannot keep up with a dynamic, ever-expanding application footprint and provide little context into why they block web requests. But Signal Sciences was designed to protect the modern applications, API and microservices no matter what architecture or infrastructure they are deployed in:
