In today’s rapidly evolving threat landscape, protecting web applications has become a priority for businesses of all sizes. Web Application Firewalls (WAFs) are critical components in safeguarding your applications against attacks such as SQL injection, cross-site scripting (XSS), and distributed denial of service (DDoS). Two popular choices in this domain are Cloudflare WAF and AWS WAF. Both offer robust features, but they cater to different use cases. This blog will compare their features, pricing, and use cases to help you decide which is the right fit for your organization.
