Certificate risk

An expired cert blocks traffic instantly

Renewal slips happen on busy teams — the cost is immediate trust loss.

  • Expiry date not tracked
  • Mixed content or hostname mismatch
  • Missing HSTS after migration
  • Weak or missing CSP on forms
  • No alert before renewal deadline

Check now; use Pro for weekly monitoring and email before expiry.

What you get

Security signals in the report

Enter your URL to instantly check your SSL certificate status, expiration date, and security header configuration. Our security scan also checks HSTS, CSP, X-Frame-Options, and other critical headers.

  • Certificate validity and expiry
  • Hostname match on the live cert
  • HSTS, CSP, X-Frame-Options where present
  • Referrer-Policy and Permissions-Policy hints
  • Cross-checks with SecurityHeaders.io when available
  • Plain-language fix notes for your host or developer
How we check TLS

Live certificate + header pass

We read the leaf certificate from our edge check and combine it with response headers.

  1. Step 1

    Submit your HTTPS URL

    Run the scan at /tools/ — HTTP URLs are evaluated for redirect and cert coverage.

  2. Step 2

    Read the live certificate

    Expiry, issuer, and hostname match are checked on the current deployment.

  3. Step 3

    Review security headers

    HSTS, CSP, and related headers are scored with remediation hints.

  4. Step 4

    Set up monitoring

    Pro users get weekly reruns and alerts when grades drop or expiry nears.

Website review

“The review was clear and practical: issue, impact, and what to fix first for trust and inquiries. We stopped debating and had a plan we could act on.”

Website fixes

“We already knew what was wrong. YourWebsiteCare implemented homepage, mobile, and booking-path fixes in a scoped round — no full rebuild, just the changes that mattered.”

Ongoing care

“We support clients but needed a named owner for one site between projects. Monthly updates, checks, and small improvements keep the site credible without hiring full-time web staff.”
