We provide every client with a Let's Encrypt SSL/TLS certificate. These are accepted by all major browsers. They don't come with some of the backing of paid certificates which many sites do not need. They provide the green padlock on your browser and make certain that all information between your computer and the file server is fully encrypted.
You can also use a Digicert certificate beyond the free one provided to you. We will purchase one for you at a price of $175 (per year). You can purchase more years for an even lower cost for you. Having an SSL certificate does help with the search engines move you up in credibility as well as if you would move to a full-featured website the certificate will move with you.
