Sucuri Web Application Firewall (WAF) by Sucuri protects websites from hacks and attacks. It filters out hack attempts, bad bots, and malicious packets, defending websites and servers from various threats. Sucuri Web Application Firewall scrutinizes and controls HTTP traffic flow between the internet and the application, working as a reverse-proxy to shield servers by requiring information to pass through it before accessing the server. It uses heuristic and signature-based techniques to detect and mitigate threats, including HTTP/2 rapid reset, CVE-2023-44487, and DDoS attacks. The WAF supports load balancing and server failover configurations, stops unknown vulnerability exploitation attempts, and uses a globally distributed Anycast Network for secure content delivery to handle large traffic spikes. It is built for all platforms and custom sites, automatically blocking fake traffic and DDoS attacks without interfering with legitimate traffic. Sucuri Web Application Firewall also includes features like virtual patching, heuristic correlation engine, smart caching options, and CMS & hosting compatibility. It provides role-based account access to the Sucuri dashboard interface and allows customization of alerts and notifications for Slack. The WAF is HTTPS & PCI compliant and offers advanced DDoS mitigation, CDN speed enhancements, high availability/load balancing, brute force protection, and emergency response SLAs.
