SSL stands for "Secure Socket Layer". It is the standard for establishing an encrypted link between the web browser and server.
An SSL certificate is important to have when accepting sales orders or other sensitive/personal information through your web site. However, not all web sites need SSL. To help decide if your site needs this level of security please read through this helpful guide.
If you find this added layer of security necessary, we'll happily install a "Let's Encrypt" certificate for you free of charge. Just drop us a line and we'll take care of the details.
