Why Do You Need An SSL Certificate?

Easy to Pick the Best SSL Certificate

That’s why I’m going to lay out each kind of SSL certificate and what they do so that you’ll be able to choose the best one that suits your company’s needs. Now, we’ll outline some common scenarios and the types of SSL that are ideal for that situation. Follow the buyer’s guide to get the optimum certificate.

Depend on Number of Domains

If only a single domain is to be protected, then a single domain or standard certificate has to be purchased with the trust level – DV, OV, or EV SSL of your choice. For example, either a small blog or a small website that doesn’t require people to hand over personal information, then a single-domain SSL with DV validation is ideal for you. However, your users are required to enter sensitive information, such as password or ID cards; we recommend a single-domain SSL that has either OV or EV validation level, depending on the size of your business.

If you have a single domain with multiple subdomains, a Wildcard SSL certificate is recommended to cover the unlimited subdomains under the same main domain. Subdomains can often encompass many uses, such as forums, logins, emails, and online shops. For these scenarios, Wildcard SSL certificate is wonderful. Keep in mind only DV Wildcard and OV Wildcard certificate are alternative for you.

If you have amounts of different Fully Qualified Domain Names (FQDNs), then a Multi-Domain SSL certificate is your ideal choice. Also, it is widely applied to Microsoft Exchange or Office Communications Server. Which differs from Wildcard Certificate, Multi-Domain (SAN) certificate supports all validation levels, that is, DV, OV and EV certificate.

Easy to Pick the Best SSL Certificate

Hinge on Your Business

If you master a blog, or a personal, business or news website where visitors do not enter their personal data or pay money, a DV SSL certificate that provide industry-standard encrypted security and entry-level credibility may meet your needs. Whereas, an OV SSL certificate is more suitable for those servers who deal with confidential information and show the organization identity to users. When it refers to e-commerce or financial enterprises, there’s never been a better choice for an Extended Validation certificate, to offer your customers assurance that they’re in the right place. Accordingly, more credibility leads to more conversions and orders for you!
