With an SSL certificate, the data exchange between the web browser and the web server is encrypted and thus protected from access by third parties.
Securing your website with an SSL certificate will show your visitors that the data transmitted through your website is secure. Especially if login data, payment information such as credit card numbers or other sensitive data are transmitted, you should definitely use an SSL certificate.
Your web pages are accessible via http(s):// instead of http:// which is also marked as secure connection in the browser.
We offer you free SSL Certificates from Let's Encrypt or Business certificates from our partner GeoTrust.
