SSL certificate

Hi All - Happy New Year to all Blocs users
I have created a site for a customer who has concerns that the site is not secure, ie no SSL Certificate.
As I am new to web design, I wonder if this is something that I can sort out from my end using Blocs 3, or is this something that should be sorted by the web hosting provider?
Any advice would be gratefully received and thank you in advance.

This needs to be done at a server level. Most web hosts use the free Lets Encrypt nowadays, which is a one click install in cPanel. You’ll also want to set up a 301 redirect in the htaccess so everything goes to the https:// version of the site.

Thanks Flashman - much appreciated.
