See what attackers see. Free scan, real report.

Sentry grades a business domain the way an attacker would: email spoofing, DNS health, security headers, encryption, exposed files, hidden subdomains, and breached staff credentials. No login, no permission needed. I run every scan personally and send a branded report within one business day.

Who it is for

  • Auto dealers, insurance agencies, and tax preparers, which federal rules require to keep a written security program
  • Any business holding South Carolinians' personal data, which can face liability under the state breach law
  • Owners who have never seen what is publicly visible about their business
  • Anyone about to renew cyber insurance and facing a questionnaire

What is included

  • Email spoofing: SPF, DKIM, and DMARC, the most common small business attack
  • DNS and domain health: DNSSEC, CAA, registrar lock, expiry risk
  • Security headers and web encryption: HSTS, CSP, clickjacking and MIME defenses, TLS
  • Information and file exposure: config and git files, leaked versions, insecure cookies
  • Attack surface: dev and admin subdomains found in public certificate logs
  • Breached credentials: staff emails in known breaches, on verified domains

How it runs

1

Scan

You give me the domain. Sentry checks only what is publicly facing; nothing touches your systems.

2

Grade

A red, yellow, green score per lens, weighted toward email spoofing.

Report and fix

A branded one page report, then a written security program and remediation path if you want the full audit.

A, 92

This site scores an A on its own scan, with 100 on DNS, encryption, and headers. Every fix in the report is one I have made myself.

See the sample report card
Free scan, $0

Full audit from $750 with a written security program. Monitoring from $250 a month with alerts and annual re certification. Every engagement is scoped to an outcome before a number is quoted, and I take on three new engagements a quarter.

Questions

Is the scan safe to run on my business?

Yes. It reads only public records: DNS, certificates, headers, and breach databases. It never logs in, never sends traffic to your systems, and never needs permission.

What do I get with the free scan?

A branded one page report with a grade per lens and the top fixes in plain English. Most owners fix two of them the same day.

Who needs the full audit?

Businesses under federal safeguard rules, anyone renewing cyber insurance, and any owner who read the free report and wants it handled.
