Cloudflare WAF is a popular choice in the cybersecurity landscape, but it isn’t a one-size-fits-all solution. In 2025, organizations are seeking WAFs that offer greater flexibility, deeper customization, Kubernetes-native support, and tighter integration with DevSecOps workflows.
Whether you’re aiming to move beyond Cloudflare’s limitations or looking for an alternative better aligned with your architecture, here are the Top 10 Cloudflare WAF Alternatives to consider—starting with a game-changer in the field: Prophaze WAF.
