Blackwall

• BotGuard Web Protection

  Cloud-based bot detection and mitigation for individual websites. Integrates at the web server level without DNS redirect. Behavioral analysis distinguishes legitimate crawlers from malicious bots.

• GateKeeper Reverse Proxy

  Distributed reverse proxy cluster for hosting providers. Sits in front of all hosted websites, providing transparent security without per-site configuration. Scales with hosting provider infrastructure.

• HTTP/3 QUIC Support

  GateKeeper supports HTTP/3 with QUIC protocol, providing better performance on high-latency and lossy connections. Automatic protocol negotiation for browsers that support it.

• Automatic SSL Management

  GateKeeper handles TLS 1.3 certificates automatically. SSL certificates are provisioned and renewed without manual intervention, reducing operational burden for hosting providers managing thousands of domains.

• WAF with OWASP Top 10

  Rule-based WAF protecting against SQL injection, XSS, CSRF, and other OWASP Top 10 attack vectors. Rules updated by the Blackwall security team.

• Behavioral Bot Detection

  Uses behavioral analysis to classify traffic as human, good bot (search engine crawlers), or malicious bot. Goes beyond simple user-agent checking to analyze request patterns and behavior.

• Rate Limiting

  Configurable rate limiting to mitigate brute force attacks, credential stuffing, and application-level DDoS. Can be applied per IP, per endpoint, or globally.

• CDN Caching Layer

  GateKeeper includes a caching layer that absorbs traffic spikes and reduces load on origin servers. Static content is served from the proxy layer, improving response times.

• Free Monitoring Mode

  Observe bot traffic and threat patterns without blocking anything. Useful for evaluation and traffic profiling. Available for both BotGuard and GateKeeper deployments.

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.
