Features Comparison
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.
Reblaze (Link11) Web Security
-
Private Cloud Deployment
Dedicated virtual private cloud per customer eliminates multi-tenant security concerns and enhances data privacy.
-
Machine Learning Detection
ML-powered traffic analysis automatically identifies and blocks malicious requests while allowing legitimate traffic.
-
Bot Management
Advanced bot detection distinguishing between legitimate users, good bots (search engines), and malicious automation.
-
DDoS Protection
Integrated Link11 DDoS mitigation with global scrubbing network for volumetric and application-layer attacks.
-
API Security
Protection for REST and GraphQL APIs with schema validation and anomaly detection.
-
Managed SOC
24/7 Security Operations Center monitoring with expert incident response and threat hunting.
