HeaderScope
Full assessment — $99

Is your business website quietly exposed?

Free instant check of your site's TLS certificate, security headers, email spoofing protection and DNS. Get grades from A+ to F, see how each gap actually gets exploited — and plain-English fixes for everything we find.

Email & DNS checks always cover the whole domain.
Scanning… checking certificate, TLS and headers, plus email authentication (SPF/DMARC/DKIM) and DNS.

What the free scan checks

One free scan, three jobs: a security headers checker, an SSL/TLS certificate test, and an email spoofing test (SPF, DMARC, DKIM). Every finding is explained the way an attacker sees it — and how to fix it.

Website & TLS

  • Certificate validity & expiry
  • TLS version & encryption strength
  • HSTS, Content-Security-Policy
  • Clickjacking & MIME-sniffing headers
  • Cookie security flags
  • Legacy TLS 1.0/1.1 still enabled
  • AI crawler posture (robots.txt)

Email spoofing

  • SPF — who may send as you
  • DMARC — what happens to fakes
  • DKIM — signed mail, key strength
  • MTA-STS & TLS reporting
  • A plain verdict: can you be spoofed?

Domain & DNS

  • DNSSEC — signed DNS answers
  • CAA — who may issue your certificates
  • Domain expiry — don't lose your name
  • Registrar & mail provider identified

Free scan vs. the $99 Full Assessment

The free scan reads your public configuration. The assessment goes hunting — and a consultant reviews every word before it reaches you.

Need the gaps actually closed?

Headers and TLS are about 5% of a real assessment. I run full security reviews for small businesses — attack surface, auth, cloud config, and a fix-it plan your team can actually follow.

Closing the gaps — implementation, hardening, monitoring — is retainer work, scoped after the assessment.

Questions

Is the free scan safe to run on my website?

Yes. It is read-only: it looks at your public certificate, response headers and DNS records — the same things any browser sees. No logins, no passwords, no attack payloads, nothing is changed or stored beyond the result you see.

What does the $99 full assessment add?

Checks the free scan does not run: exposed sensitive files (.env, .git), your full subdomain attack surface from public certificate records with live-host analysis, mail-server spam blocklists, mail-server encryption and certificate checks, your AI security surface, and dangling DNS records an attacker could claim. You also get a priority fix plan and a report that is personally reviewed by a cybersecurity consultant before it is emailed to you.

How fast do I get the $99 report?

The deep scan runs as soon as payment clears, and the reviewed report is delivered by email within one business day.

Will you fix the problems you find?

The report gives you (or your IT person) a plain-English fix for every finding, in priority order. Hands-on remediation — implementation, hardening and monitoring — is available as consulting retainer work.

Why this matters for a small business

Missing headers invite attacks

Security headers tell browsers how to protect your visitors. Without a Content-Security-Policy and clickjacking protection, your site can be used to attack the customers who trust it — and most small-business sites are missing at least one.

Spoofed email is how invoices get faked

If your SPF, DMARC and DKIM records are weak, anyone can send email that looks exactly like it came from you — a fake invoice with "new bank details" is the classic. One DMARC record at full enforcement stops it cold.

It also affects your real mail

Gmail and Outlook trust domains with proper email authentication. Fixing these records means your real quotes, invoices and password resets are less likely to land in your customers' spam folders.
