F5 BIG-IP Advanced WAF

• Behavioral Analytics

  Machine learning builds dynamic security policies by analyzing live application traffic patterns. The WAF automatically adapts to application changes and learns normal behavior, flagging anomalies without manual rule updates. Significantly reduces false positives compared to static rule-based WAFs.

• Proactive Bot Defense

  Multi-layered bot detection using JavaScript challenge, device fingerprinting, and behavioral analysis. Identifies automated attacks, web scraping, account takeover attempts, and credential stuffing bots. Client-side telemetry detects sophisticated bots that bypass simple CAPTCHA challenges.

• Credential Protection and DataSafe

  DataSafe encrypts sensitive HTML form fields in real-time within the browser, protecting credentials from man-in-the-browser malware. Leaked credential check compares login attempts against known breached databases. Together with bot defense, this provides the strongest credential protection of any WAF on the market.

• API Security

  Import OpenAPI/Swagger specifications to automatically generate API security policies. Enforces schema validation, parameter types, rate limits, and protocol rules for REST, GraphQL, and gRPC APIs. Automatic API discovery identifies shadow APIs.

• L7 DDoS Mitigation

  Application-layer DDoS detection using stress-based analysis, transaction tracking, and behavioral anomaly detection. Automatically mitigates attacks while preserving legitimate user access. Heavy URL detection identifies resource-intensive endpoints being targeted.

• iRules Scripting Engine

  Tcl-based scripting language providing complete programmable control over traffic management and security decisions. Can inspect, modify, redirect, or drop traffic based on any combination of headers, payload content, cookies, or application state. Unmatched flexibility for complex application architectures.

• AI-Powered WAF Risk Scoring (2026)

  Integrates with F5 Distributed Cloud Web App Scanning to automatically convert vulnerability scan findings into virtual patches. Security teams can identify threats and deploy protections without manual rule creation.

• Post-Quantum Cryptography (2026)

  BIG-IP v21.1 introduces support for post-quantum encryption algorithms, preparing applications for the transition to quantum-resistant cryptography as recommended by NIST.

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.
