Free Website Security Check
Quick public website trust check for DNS, HTTPS, email authentication, security headers, and reputation signals. Full fix plan is available by request.
Enter a public domain to see the visible trust posture. The free check is intentionally limited for safety: it does not run public port exposure scans, reveal raw IP evidence, enumerate sensitive paths, or publish exploit-style details.
Only scan domains you own or are responsible for. For deep scan and managed cleanup, request the full fix plan.
Need this for a company or multiple domains?
Request the enterprise assessment path. Hostao confirms scope first, then prepares the protected executive report, risk register, remediation queue, retest, and proof pack.
The real problem this solves
| Customer pain | Hostao answer |
|---|---|
| Reports are too technical SMBs and agencies often receive scanner output that names CVEs or headers but does not tell who should fix it or what business risk comes first. | Every finding needs a plain-English impact, fix layer, owner type, and Hostao-can-fix flag. |
| False positives waste time Generic scanners flag everything with similar severity, including context-only findings on parked domains and customer sites outside scope. | Use ownership guardrails, customer exclusions, mail-intent checks, and "context, not failure" labels. |
| No one owns remediation Security, DNS, hosting, SEO, and support ownership are split, so issues remain open even when the fix is simple. | Route each action to Cloudflare, origin hosting, app code, DNS/email, account owner, or customer approval. |
| Trust problems are not only vulnerabilities Broken TLS, weak email authentication, missing security headers, blacklist signals, and bad third-party scripts all hurt trust, deliverability, and conversion. | Show Security + Trust together: headers, SSL, email auth, DNS, reputation, scripts, and customer-facing impact. |
Choose the right path
| Path | Best for | What customer gets |
|---|---|---|
| Free / Public Later | Lead generation for one domain | Quick outside-in trust check SSL, headers, email auth, blacklist, DNS basics, limited subdomain signals |
| Internal Hostao Portfolio | Owned projects and approved domains | One queue for what Hostao should fix first Portfolio scoring, owner/fix-layer routing, customer exclusions, stale issue tracking, report readiness |
| Paid Analyst Report | SMBs, agencies, domain buyers, migration clients | Plain-English security and trust report with fix path Manual validation, business impact, fix plan, retest proof, PDF/client summary |
| Managed Security Fix | Hostao hosting/support clients | Hostao fixes what is safe to fix Cloudflare headers, email auth, SSL, DNS cleanup, app header guidance, support ticket routing |
What stays private
Common service ports and raw exposure evidence stay in the admin-only scanner.
Owner, SLA, retest, and proof workflow stays behind internal access.
Raw IPs, detailed subdomain evidence, and internal portfolio context are not shown publicly.
