What gets checked
Every check is read-only. Sentinel never fuzzes, exploits or attempts to bypass authentication on your target.
Transport & TLS
HTTPS reachability, redirect chain, HSTS strength.
Security headers
CSP, frame options, nosniff, referrer and permissions policy.
Cookies & CORS
Secure, HttpOnly, SameSite flags and cross-origin exposure.
Attack surface
Exposed .env, .git, robots, sitemap, security.txt.
Technology fingerprint
Stack, CDN and version banners leaking from responses.
AI visibility
llms.txt, structured data, GPTBot / ClaudeBot / PerplexityBot rules.
How the scores work
Your Security Score starts at 100 and drops by weighted penalties for every finding — critical issues cost the most, informational notes barely register. The same input always produces the same score, so you can track progress across scans.
Your AI Visibility Score blends citation coverage, answer-engine optimisation, generative-engine optimisation, classic SEO, entity coverage and content authority.
