We use bounded, read-only checks against public sources.

External reliability evidence before an incident becomes a ticket.

Sentryx observes public DNS, HTTPS behavior, TLS certificates, mail-security records, and resolving internet-facing services. The report turns those signals into a concise outside-in hypothesis with clear evidence, limitations, and next actions.
