Why you need SSL
Browsers, like Google Chrome, Mozilla, Internet Explorer mark pages without SSL encryption as not secure. This can have a negative effect on the trustworthiness of your website. If you have an SSL certificate, your site's URL will start with the prefix "https" and a green padlock icon will be displayed in the browser bar, showing your visitors your site is secure and their data is safe. Pages that are protected with SSL receive better search engine rankings and are more likely to be trusted by visitors.
Types of SSL certificates
Domain Validated (DV)
If you are just starting out or want to use the SSL certificate in order to secure your personal website or blog, then usually the domain validated SSL (DV) will suffice.
This way, all traffic is encrypted but no further validation is conducted. DV Certificates are the right solution for simple websites like blogs, personal websites, and simple one-page websites. Do not use a DV SSL Certificate for eCommerce or other applications which require a higher level of trust.
Organization Validated (OV)
If you are doing any business online, you should at least use an OV SSL. When you're handling any kind of customer data, organization validation (OV) will make sure that the certificate is really from your organization, and that the domain belongs to you, not a third party.
This helps you to protect your business and customers from phishing websites. Organization validation is a great way to secure a company website, a forum, or any other website with a login page that does not transfer payment data. Customers' usernames and passwords will be transferred with end-to-end encryption.
Extended Validation (EV)
If you are an entity with an increased level of trustworthiness, the extended validation certificate can transfer this assurance onto your website. The symbol of this trust is the green address bar in the browser, which comes with the EV SSL.
This is why not only banks and big eCommerce organizations rely on extended validation certificates, but government agencies also use them for secured transactions. eCommerce websites should rely on the level of trust only an EV Certificate can provide. Only extended verification can guarantee the real origin of a website and the safety of data such as customer information, credit card numbers, and other payment details.
These certificates do just as their name suggests – cover multiple domains with just a single solution.
One Multi-Domain SSL certificate can cover up to 250 total domains, depending on the brand of certificate.
Multi-Domain certificates are an extremely convenient option for businesses that own a lot of different TLD extensions and want to cover them all with up to 256-bit encryption without having to purchase and install separate SSLs for each one.
Since these certificates are available in EV, OV, and DV options, you're sure to find a Multi-Domain certificate that suits your needs.
Wildcard SSL certificates cover one domain name and an unlimited amount of sub-domains.
For example, a Wildcard SSL certificate can cover www.domain.com, email.domain.com, login.domain.com, xyz.domain.com, etc.
These certificates are extremely popular, affordable, and convenient solutions – since most domains have subdomains. Also, they are available in both DV and OV types, with no EV Wildcard SSL certificate currently available.
Wildcard SSL certificates offer up to 256-bit encryption on all of the domains and subdomains that they cover.
Multi-domain Wildcard Certificates
There's nothing a Multi-Domain Wildcard SSL certificate can't secure.
For any company or organization with a complicated public-facing web infrastructure, a Multi-Domain Wildcard is the perfect security solution.
Depending on CA, you can secure up to 25, 100 or 250 different domains or IPs and all accompanying sub-domains.
Nothing saves you more time, money and effort than securing your entire web presence with a single SSL certificate.
Code Signing (CS)
Code Signing certificates aren't traditional SSL/TLS certificates, but they play an important and expanding role in online security and integrity.
These are certificate-based digital signature algorithms that verify a piece of code hasn't been tampered with since it was signed by the author.
We like to think of it as a "digital shrink wrap" that validates code is being authentic and in its original form. It is the web's tamper-proof system for software downloading.
Code signing certificates are used and recognized by all major operating systems like Apple OS X, Linux, and Windows.
Email & Document Signing
These increasingly popular certificates can validate the identity of both the email sender and the recipient.
Email signing certificates are especially important within organizations, to ensure that the proper secure communication practices are being followed.
