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.

  • 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.

Sophos Firewall (XGS)

  • Reverse-Proxy WAF

    Apache-based reverse proxy that protects published web servers against SQL injection, cross-site scripting, directory traversal, and other common web attacks.

  • Form Hardening

    Signs and validates form fields to prevent manipulation of submitted web forms.

  • URL Hardening

    Restricts accessible URLs based on the learned structure of the protected application.

  • Cookie Signing

    Cryptographically signs cookies to detect and block tampering.

  • Reverse-Proxy Authentication

    Adds basic or form-based authentication policies in front of published web servers via WAF rules.

  • Antivirus Scanning

    Scans uploads and traffic to protected web servers for malware as part of Web Server Protection.
