Features Comparison
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.
