Check your website security from the public internet.
Enter a domain to review public hosts, DNS, HTTPS, TLS certificates, baseline security headers, and email-security records. You receive the observed evidence, why it matters, and a practical next step.
A clear domain health report, not a vague score.
Every result is tied to a public observation. Sentryx separates confirmed evidence from items that need review and shows how each recommendation follows from the observed signal.
Domain and host discovery
Map public hosts and supported DNS signals connected to the domain, then identify monitoring candidates and names that deserve an owner review.
HTTPS and certificate health
Observe HTTPS availability, certificate expiration, issuer, hostname validity, trust chain, and TLS behavior.
Web and email-security signals
Check baseline response headers and supported email-security records such as SPF and DMARC using public information.
Public evidence with explicit limits.
The free report is an outside-in snapshot, not a penetration test, safety certification, or guarantee that a website has no vulnerabilities.
Discover supported public records and validate hosts when resolution evidence is available.
Check HTTPS, TLS certificate details, baseline response headers, and supported email-security signals.
Connect each finding to the exact public signal, confidence level, and recommended next action.
No login, exploitation, internal access, response-body storage, or port scanning in the free public report.
What this website security check means.
What does the website security check test?
The check observes public hosts, DNS records, HTTPS responses, TLS certificate details, baseline security headers, and email-security records.
Is this a penetration test?
No. It is a read-only outside-in snapshot. Sentryx does not log in, exploit systems, access private data, store response bodies, or run a port scan in the free public report.
Can I monitor a finding after the scan?
Yes. Selected hosts can become uptime, SSL certificate, HTTP, TCP, DNS, and supported change monitors.
