What type of SSL do I Need?

Choosing the right SSL based on your security needs

Selecting the right SSL Certificate depends on a variety of factors including security level, trust level, and visibility to the web visitor. All pages that require a visitor to enter login details or private information like credit card details require some level of SSL encryption, and many website owners choose to encrypt their entire site. 

Encrypting every page and domain is recommended for a few reasons. One, your site visitors will know that their browsing activity is encrypted, and another is that encrypting every page now helps your pages rank better in Google’s search engine algorithm. 

Let us help you find the right certificate

To help you chose what type of SSL Certificate you need, start by selecting your use case:
