Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
CrowdSec Web Application Firewall
- You want to start with a free tier
- You're using: Linux, Docker, Kubernetes, FreeBSD, Windows (beta)
Shield Security
- You need: WordPress site owners wanting automated hands-off security, sites plagued by bot traffic and automated attacks, agencies using MainWP for site management
- You want to start with a free tier
- You prefer open-source solutions
- You're using: WordPress (self-hosted)
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
