Option #1. Single Domain
Single domain (or single-name) SSL certificates protect a single domain. This SSL type really works well for simple and straightforward content-based sites. These sites include B2B sites, e-commerce ones where all transactions occur on a single domain. Someone has to get an authenticated domain ownership when she/he wants to get a “Domain-validated”.
Option #2. Multi-Domain (SAN)
Multi-domain SSL certificates are also what they sound like. Multi-domain SSL certificates are also referred to as “SAN” (for Subject Alternative Names). With SAN and one multi-domain SSL certificate, it will cover a suite of sites. So, they provide flexibility for covering sites that might go away or not yet exist.
Option #3 Wildcard

With this single wildcard SSL certificate, you can simplify the mess, and it also protects the main site.
Option #4 Organization
Organization SSL certificates works to authenticate a company’s identity and information, such as the company’s primary address, and etc. You may think that this is similar to single domain. But in organization SSL certificates, you will get more content-based sites. By this, you don’t need to secure an e-commerce or payments component.

It will also show a green address bar on most modern browsers for your troubles. In Chrome, you’ll also get the company name like this Twitter example below:
Credibility is what you’re paying for here. But, the secure connection uses on your site are that different than any other reputable SSL connection.
