Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
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
SonicWall Web Application Firewall
- You need: Organizations already using SonicWall network firewalls, on-premise deployments requiring hardware WAF, mid-market companies needing PCI DSS compliance
- You're using: Hardware appliance, Virtual appliance (VMware, Hyper-V, AWS, Azure)
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
