An SSL certificate protects the traffic between your website and its visitors by encrypting the data transfer. With all of Nordweb's hosting plans you get a free Let's Encrypt SSL certificate.
The Enhance control panel installs the SSL certificate automatically when you add a domain to your website. The certificate is also renewed automatically before it expires.
Make sure all traffic is directed to the HTTPS version:

ERR_TOO_MANY_REDIRECTS, the site redirects itself in circles »
