SSL (today called TLS) is the security protocol that encrypts the connection between a visitor's browser and your website. When an SSL certificate is installed, your address starts with https:// and the browser shows a padlock.
- Passwords, card details and form data cannot be read by third parties.
- On sites without SSL, browsers show a Not secure warning.
- Google prefers sites that use HTTPS.
What does SSL provide?
| Feature | Description |
|---|---|
| Encryption | Data between the browser and the server cannot be read by anyone in between. |
| Authentication | The certificate shows that the site really belongs to that domain. |
| Data integrity | Data cannot be altered on the way. |
Which certificate should I choose?
- Blogs and company websites: The free Let's Encrypt certificate included with your hosting is enough.
- Online shops and membership sites: A DV certificate with warranty or an organisation-validated OV certificate is recommended.
- Many subdomains: A wildcard SSL protects them all with one certificate.
