ModSecurity Open Source WAF

• OWASP Core Rule Set

  Comprehensive, community-maintained rule set providing protection against OWASP Top 10 and more.

• Custom Rules

  Powerful SecRule language for creating custom detection logic based on any request/response attribute.

• Real-Time Request Analysis

  Inspect and analyze every HTTP transaction with access to full request and response data.

• Audit Logging

  Detailed logging of security events for forensics, compliance, and monitoring.

• Virtual Patching

  Create temporary rules to protect against vulnerabilities while permanent fixes are developed.

• Data Loss Prevention

  Inspect response bodies to prevent sensitive data leakage.

Monarx

• Real-time Filesystem Monitoring

  Monitors file system operations at the server level in real-time. Inspects files as they are being written, catching malware regardless of the delivery vector (HTTP, FTP, SSH, plugin updates).

• Pre-write Malware Blocking

  Blocks malware before it is written to disk, not after. This prevents the malware from ever executing, eliminating the window of compromise that exists with scan-and-clean approaches.

• Vector-agnostic Detection

  Detects malware regardless of how it arrives, whether through web exploits, compromised FTP credentials, malicious plugin updates, or supply chain attacks. Traditional WAFs only see HTTP traffic and miss other vectors.

• Shared Hosting Protection

  Protects all websites on a shared hosting server with a single deployment. No per-site configuration required. Particularly valuable for shared hosting environments where hundreds of sites share the same server.

• Malware Analytics Dashboard

  Dashboard showing malware detection events, trends, and affected accounts. Hosting providers can identify compromised accounts and take targeted action.

• Automatic Signature Updates

  Malware signatures are updated automatically as new threats are identified. The Monarx team maintains and updates the signature database without requiring manual intervention from hosting providers.

• Low Performance Overhead

  Designed to run on production hosting servers without noticeable performance impact. Filesystem-level inspection is lightweight compared to full traffic inspection by traditional WAFs.

• API Integration

  API for integrating Monarx data into hosting provider management systems, ticketing workflows, and customer dashboards. Enables automated responses to malware detection events.
