An SSL certificate is a digital certificate verifying your identity. Without an SSL certificate, your visitors will get a warning message from their web browser. With shared SSL you use your hosting company's SSL certificate, however, with private SSL you must purchase your own SSL Certificate. SSL essentially allows data to be passed between our server and other computers in a secure encrypted format. You can purchase an SSL from Midphase at https://chi.midphase.com or by contacting our Sales team.
