Features Comparison
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.
