SentryScore checks SSL, email protection, breach history, and security headers — and gives you a plain-English action plan in under 60 seconds.
Every scan runs five independent checks against publicly available signals — no credentials, no installs, no agents.
Grades your certificate configuration via SSL Labs. Catches weak protocols, expired certs, and missing HSTS.
25 ptsChecks SPF, DKIM, and DMARC records. Without these, anyone can impersonate your domain in phishing emails.
25 ptsChecks HaveIBeenPwned for known data breaches tied to your domain. Know before your clients do.
20 ptsVerifies HSTS, CSP, X-Frame-Options, and other browser security controls are in place.
15 ptsChecks MX records, DNSSEC, CAA records, and other DNS hygiene signals that affect deliverability and security.
15 ptsEvery domain falls into one of four bands. Most small businesses land in At Risk or Vulnerable — often without knowing it.
SentryScore is designed for business owners who want a straight answer — not a 200-page enterprise security assessment.
A basic scan is always free. Full reports and ongoing monitoring are paid.
Yes — completely safe. SentryScore only reads publicly available information (DNS records, HTTP headers, SSL certificates). It does not send traffic to your servers beyond a single HTTP request to check headers, and it never attempts to log in or probe for vulnerabilities.
Your IT provider or registrar does. Share the report with them — the action plan tells you exactly what to ask for in plain English. Most findings take 15–30 minutes for a technician to fix.
A low score means your domain is missing standard protections, not that you've already been compromised. Think of it like finding out your front door doesn't have a deadbolt — important to know, not a reason to panic. The action plan tells you what to fix first.
SentryScore checks your publicly visible security signals — the things attackers check before targeting you. A full audit goes deeper (internal network, access controls, employee practices). This is the first step: find out where you stand from the outside.
No — SentryScore is an independent product by Guardrail Works. We have no affiliation with sentry.io or any other company named Sentry.
