The Sucuri Website Firewall is designed to protect web applications from various types of malicious traffic and attacks. Technically, it operates as a cloud-based Web Application Firewall (WAF) that acts as a reverse proxy, intercepting and inspecting all incoming HTTP/HTTPS requests before they reach your server.
The architecture of the Sucuri Firewall is built on a global Anycast network, which provides high availability, redundancy, and failover capabilities. This setup ensures that traffic is routed through the nearest node, enhancing performance and reducing latency. To activate the firewall, you need to change your DNS A records to point to Sucuri's firewall IP addresses, allowing all traffic to be filtered through their network before reaching your server.
Key operational considerations include the need to limit access to your hosting server to prevent bypassing the firewall by attackers who might know your hosting IP address. Additionally, the firewall integrates with various CDN providers and offers virtual patching and hardening to protect against known vulnerabilities, even if your site's software is not up-to-date.
From a technical standpoint, the Sucuri Firewall uses a combination of blocklisting and heuristic techniques to identify and block malicious requests. It also includes features like DDoS protection, brute force protection, and bot blocking. The firewall automatically enables SSL certificates for end-to-end encryption, with the option to upload custom SSL certificates on higher plans. Performance optimization is another key aspect, with the firewall reducing server load by up to 80% through its integrated CDN and caching mechanisms.
