Over 100 enterprise IT professionals rated our web application and API protection solution for its ability to:

  • Block attacks with virtually zero false positives
  • Integrate with a diverse array of DevOps and security platforms
  • Provide visibility within a unified management console
  • Run in full blocking mode—which 90% of our customers do

"False Positive was my biggest concern when implementing the WAF, but I have received zero complaints from users, which I think is excellent. We can easily protect our services without the need for complex rule tuning that is often required with other companies' products. I can also recommend the easy to understand Web UI and the ease of installation."
