Having an SSL certificate is a necessity for customers to feel secure on your site — especially if they’re inputting any data on the site. As more browsers follow Google’s lead in marking all HTTP sites as “not secure,” this is becoming an even more important issue. However, as more companies shift from HTTP to HTTPS, organizations like Let’s Encrypt have made access to free SSL certificates possible in a pursuit of making the web more secure for everyone. This includes free wildcard SSL certificates.
