Next-Generation Web Application Firewall (WAF)

Cloud-Native Web Application Security

Get Active Protection Across Your Entire Web App Footprint

Your application footprint is growing more complex and varied with faster development cycles and the shift to cloud–whether private or public. Legacy rules-based web application firewalls (WAFs) won’t scale, and a next-gen approach is needed.

Our dual agent-module software installs easily and supports any application without impacting performance to protect against any attack, with integrations with many DevOps toolchain products for cross-team visibility.
