You need an SSL certificate if you are handling any sensitive customer data. Ecommerce sites, which usually handle credit card payments, definitely need an SSL certificate. A site that allows for personal or private communication — email, messaging, file storage — needs a certificate.
Even if you don’t have a specific requirement for an SSL security certificate, you may want to get one anyway. At SiteStop all our hosting package include SSL certificate for you to use. HTTPS promotes safer browsing generally and web giant Google agrees with this.
