🛡️ Enterprise Security & Reliability

• Strict Anti-SSRF Protection: Private IP ranges (RFC 1918), link-local addresses, and cloud provider metadata servers (169.254.169.254) are permanently blocked.
• Fail-Safe Synthetic Intelligence: If a target domain has strict Cloudflare challenge or is temporarily offline, the engine falls back gracefully to deterministic intelligence rather than throwing a 500 error.
• Strict Payload & Memory Limits: Max 512 KB HTML stream and 6-second timeout guarantee lightning-fast response times.
