Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
Google Cloud Armor
- You need: GCP-native applications, organizations using Google Cloud, applications needing reCAPTCHA integration, multi-cloud with GCP component
- You're using: Google Cloud Load Balancer (HTTP/S, TCP/SSL Proxy), Cloud CDN, Cloud Run, GKE
HAProxy Enterprise WAF
- You need: High-traffic applications already using HAProxy for load balancing, organizations wanting integrated WAF and load balancing without separate appliances, teams that prioritize low latency and accuracy over rule customization, enterprises running multi-cloud or hybrid deployments
- You're using: Linux (RHEL, Ubuntu, Debian, CentOS, Amazon Linux), Docker, Kubernetes, AWS, Azure, GCP, FreeBSD, virtual appliance
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
