Sucuri Security is a website security provider that delivers cloud-based protection, monitoring, and incident response for websites and web applications.
- Website application firewall (WAF) and Distributed Denial of Service (DDoS) protection for websites and web applications (web security)
- Malware scanning, detection, and cleanup services for compromised sites (website security)
- Security monitoring, integrity checks, and alerting for web properties (security monitoring)
- Performance optimization via global content delivery and caching for protected sites (content delivery and optimization)
- Security hardening guidance and incident response services for ongoing website protection (security operations)
More About Sucuri Security
Sucuri Security focuses on protecting websites and web applications through a cloud-based security stack that is positioned between end users and the origin web server. Enterprise and institutional customers typically deploy Sucuri by pointing Domain Name System (DNS) records to Sucuri’s network, which then inspects and filters HTTP/HTTPS traffic before forwarding permitted requests to the origin. This architecture allows organizations to add security controls, performance optimization, and monitoring without redesigning application code or changing hosting providers.
A core offering is its website application firewall (web security), which is designed to mitigate attacks such as Structured Query Language (SQL) injection, Cross-Site Scripting (XSS), XML-RPC abuse, brute-force login attempts, and DDoS events at the Hypertext Transfer Protocol (HTTP) layer. The Web Application Firewall (WAF) uses rule-based filtering, virtual patching, and IP reputation to inspect requests. TLS/SSL termination is handled at Sucuri’s edge, with support for HTTPS enforcement and certificate provisioning, which enables encrypted traffic between clients and the Sucuri edge, and optionally between Sucuri and the origin server.
Sucuri also provides malware scanning and cleanup services (website security). These include remote scanners that check public-facing content for known malicious signatures, blacklisting indicators, and anomalies, as well as server-side scanning for organizations that provide access. When a compromise is detected, Sucuri’s incident response team performs malware removal, backdoor detection, database cleanup, and search engine blacklist review. This service is often used by enterprises running content management systems such as WordPress, Joomla, or Drupal, where plugin or theme vulnerabilities can be exploited.
Security monitoring and integrity checks (security monitoring) are part of the ongoing service. Sucuri tracks changes to core files, monitors DNS records, Secure Socket Layer (SSL) certificate status, and uptime, and generates alerts when configuration or availability issues occur. This monitoring is intended to complement existing Security Information and Event Management (SIEM) or logging tools by focusing on website-specific indicators and can be integrated into broader Security Operations (SecOps) workflows.
Sucuri includes performance optimization and content delivery (content delivery and optimization) by caching static content on a distributed network of data centers and applying content acceleration techniques such as compression and HTTP/2 support, where available. This positions the service in a category similar to content delivery networks (CDNs) that combine WAF, DDoS mitigation, and caching, although Sucuri is focused on website security use cases rather than general-purpose application delivery.
For directory and taxonomy purposes, Sucuri Security fits into categories such as WAF services, website malware detection and response, DDoS protection for websites, website security monitoring, and performance optimization with integrated Content Delivery Network (CDN) capabilities. Its offerings are used by organizations that want to protect public-facing websites, blogs, e-commerce platforms, and marketing sites without running their own WAF infrastructure or building custom malware detection pipelines.
