Free website security check

A free, instant scan of your site’s HTTPS setup, SSL certificate, security headers and email authentication. Clear results in plain English, no account needed.
Website Health & Security Checker
Enter a domain and we will read what its public configuration says about HTTPS, its certificate, a few response headers and its email records. Free, with no account.
What the free security check looks at
Every finding is explained in plain English, with a clear next step for anything that needs attention.
HTTPS and redirects
Confirms your site loads over an encrypted connection and that visitors on plain http:// are sent to the secure version.
SSL/TLS certificate
Verifies the certificate against trusted authorities and flags it if it has expired or runs out within two weeks.
Security headers
Checks HSTS, Content-Security-Policy, X-Content-Type-Options, clickjacking protection and Referrer-Policy.
Email authentication
Looks up your SPF, DMARC and MX records, the DNS settings that stop other people sending email as your domain.
Free tools for the numbers, too
Quick calculators for freelancers and small businesses. They run entirely in your browser, and nothing you type is sent anywhere.
