41 automated scanners executing in parallel. Probing HTTP security headers, SPF/DKIM/DMARC email spoofing defense, AI crawler indexing permissions, and structured Schema.org knowledge graph depth.
Why We Built It
More software than ever is shipped by teams building rapidly with AI coding tools like Cursor, Claude, Copilot, Lovable, Bolt, and v0. That velocity is a gift, but it routinely deploys web applications with exposed API keys, missing access controls, unauthenticated endpoints, broken structured data, and absent email authentication.
Bear Systems engineered the Bear Sentinel™ Engine to close that vulnerability gap: enterprise-grade diagnostic auditing that anyone can execute in under 3 seconds, with concrete copy-paste remediations and enterprise hardening runbooks.
Authoritative Standards Alignment
The engine executes dozens of parallel non-intrusive network handshakes, DNS queries, and document parses against published global standards:
- [01]OWASP Top 10 (2021/2025) ↗ — Web application vulnerability mapping and injection detection.
- [02]RFC 7208 / 6376 / 7489 ↗ — SPF, DKIM 2048-bit, and DMARC email spoofing defense.
- [03]Google Search Central ↗ — Technical SEO, metadata bounds, and canonical integrity.
- [04]Princeton GEO (arXiv:2311.09735) ↗ — AI answer engine crawlability (GPTBot, ClaudeBot, PerplexityBot).
- [05]WCAG 2.2 Level AA (EAA 2025) ↗ — Accessibility landmarks and form label binding.
