ModSecurity Open Source WAF and Sucuri Website Security take fundamentally different approaches to web application security. Understanding your infrastructure and team capabilities will help determine which approach fits your needs.
Overview
ModSecurity and Sucuri represent self-hosted vs managed web security. ModSecurity is the open-source WAF engine you install and manage on your own server. Sucuri is a managed service: change your DNS, and Sucuri filters all traffic through their cloud WAF before it reaches your server.
With ModSecurity + OWASP CRS, you get unlimited customization and zero cost, but you handle rule updates, false positive tuning, server hardening, and incident response. With Sucuri, you get managed WAF rules, a CDN, DDoS protection, malware monitoring, and a team that will clean up your site if it gets hacked, starting at $199/year.
Technical teams who want full control choose ModSecurity. Website owners who want protection without the operational burden choose Sucuri.
