What it does
SentryScore scans your business domain for SSL issues, email vulnerabilities (SPF/DKIM/DMARC), breach history, HTTP header gaps, and DNS hygiene — then gives you a score from 0–100 with a plain-English action plan. Built for small practices and firms that can't afford enterprise security tools. Free scan always. Full PDF report $49. Weekly monitoring $97/mo.
Find out how secure your business domain really is. Free instant scan — checks SSL, email spoofing protection (SPF/DKIM/DMARC), breach history, and security headers. Get your score in 60 seconds.
SentryScore checks SSL, email protection, breach history, and security headers — and gives you a plain-English action plan in under 60 seconds. Can someone send emails pretending to be you? Check your SPF, DKIM, and DMARC records instantly — with plain-English fix steps. 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. Checks SPF, DKIM, and DMARC records. Without these, anyone can impersonate your domain in phishing emails. Checks HaveIBeenPwned for known data breaches tied to your domain. Know before your clients…from sentryscore.com
