Domain Health Monitor
Instantly check your domain's SSL certificate, DNS health, email authentication, security headers, and more. Get an overall health grade in seconds.
What We Check & Why It Matters
SSL Certificate
Verifies your HTTPS certificate is valid, trusted, and not expiring soon. An expired cert shows security warnings to all visitors.
DNS Health
Confirms your domain resolves correctly with A records. Without this, your site is completely unreachable.
Email Authentication
Checks for SPF and DMARC records that prevent email spoofing and improve deliverability to inboxes.
Security Headers
Scans for HSTS, X-Frame-Options, CSP and other headers that protect against XSS and clickjacking attacks.
Response Time
Measures how fast your server responds. Slow servers hurt Google rankings and cause visitors to leave.
HTTP Redirects
Confirms unencrypted HTTP traffic is redirected to HTTPS automatically — essential for SEO and security.
