Verify SSL/TLS certificates for any domain. Check issuer, expiration, protocol version, and overall SSL health of your website.
| Version | Status | Security |
|---|---|---|
| SSL 2.0 | ❌ Deprecated | Critically insecure |
| SSL 3.0 | ❌ Deprecated | Vulnerable (POODLE) |
| TLS 1.0 | ⚠️ Legacy | Weak (should disable) |
| TLS 1.1 | ⚠️ Legacy | Weak (should disable) |
| TLS 1.2 | ✅ Current | Secure (widely used) |
| TLS 1.3 | ✅ Latest | Most secure & fastest |
SSL/TLS certificates encrypt the connection between your website and visitors, protecting sensitive data like passwords and credit card numbers. Google also uses HTTPS as a ranking factor — sites without SSL are penalized in search results and shown as "Not Secure" in browsers.
| Type | Validation | Use Case |
|---|---|---|
| DV (Domain Validated) | Domain ownership only | Blogs, small sites |
| OV (Org Validated) | Organization verified | Business websites |
| EV (Extended Validation) | Full legal verification | E-commerce, banking |
| Wildcard | Covers subdomains | *.example.com |
