What is WAF?

A Web Application Firewall (WAF) is a security layer that sits between your application and the internet. It filters, monitors and can block HTTP traffic to protect your site from common attacks and abuse.

Our WAF helps you keep your site protected and avoid downtime caused by malicious traffic. You can block or allow requests by country, ASN, IP or User-Agent. You get real-time or deferred processing: either check each request via API before it hits your app, or log traffic and apply rules in the background. We also offer rate limiting (throttling) by path pattern and a global rules engine updated daily with known bad actors.

Integration is simple: send request data to our API (IP, path, User-Agent, etc.) and we tell you whether to allow or block. No need to deploy agents on your servers—just HTTP calls from your existing stack.
