Expired certificates, spoofed email, exposed files and outdated libraries are how small sites get hit. Sentinal catches them before attackers do.
35+ deterministic checks on SSL, DNS, email, security headers, exposed files and known CVEs — every finding backed by evidence.
Plain-English explanations of how issues connect and what to fix first. The AI never invents findings — it only explains real ones.
Mark an issue fixed, re-scan, and Sentinal confirms it's truly resolved. A finding closes only when the check passes.
