Secure Sockets Layer (SSL) precedes the Transport Layer Security (TLS) we use today. It is a cryptographic protocol for network security. Despite being depreciated, the term SSL is still used to refer to TLS.
A standard security technology that provides secure communications between a web server and a browser. SSL uses a combination of public key and private key encryption to protect sensitive information like credit card numbers, login credentials, email addresses, etc. Furthermore, HTTPS, padlock and green address bar ensure users for a safe website browsing and online transactions.
Domain Validated (DV) SSL Certificates deliver the easiest & quickest solution to secure a domain since only the domain name is verified during the validation process. Anyone who can demonstrate control of a registered domain can get this SSL security within minutes of ordering. DV certificates are suitable for small or start-up businesses.
To receive an Organization Validated (OV) SSL certificate the customer must demonstrate control of a registered domain and provide certain pieces of company information that It can be verified using third-party sources. The OV certificate is a good solution for business sites to increase user trust as the certificate certifies and displays company information to prove ownership of the website.
An Extended Validation (EV) certificate is the premium SSL certificate. It provides great assurance to customers by displaying your organization's verified details in all major browsers. In browsers like Microsoft Internet Explorer, EV SSL displays your organization's name and/or domain name in green on the address bar, formerly known as 'green address bar'. Extended Validation (EV) SSL certificates provide a secure connection and provide visible proof to establish business identity validation.
An Extended Validation (EV) SSL Certificate is the only certificate that displays your verified company name in all major web browsers. Now-a-days different browsers have different policies for displaying EV SSL.
Internet Explorer shows entire address bar in green background color along with displaying the organization's legal operating name on the address bar.
In browsers such as Microsoft Internet Explorer, EV SSL displays your organization's name and/or domain name and padlock symbol in green on the address bar.
Google Chrome and Firefox shows organization's verified name and details after clicking on the padlock sign.
To have an EV SSL Certificate you must demonstrate that your business is an official company registered with a government authority. You cannot qualify for any EV SSL Certificate if you are a Sole Proprietor or a Partnership registered in the U.K.
All available SSL Certificates offer www and non-www coverage automatically, except for specialty certificates such as multi-domain (SAN) certificates.
A Wildcard SSL Certificate secures a single main domain (domain.com) and an unlimited number of subdomains (mail.domain.com, blog.domain.com, login.domain.com etc.) A wildcard SSL certificate is annotated with an asterisk, as in *.domain.com.
Multi Domain or SAN (Subject Alternative Names) certificates protects multiple domain names with a single certificate (domain.com, example.net, website.org etc). The available multi-domain certificates can cover up to 250 domains with just one certificate.
A wildcard SSL certificate secures a single domain (domain.com) and an unlimited number of sub-domains at a specific level. A multi-domain (SAN) certificate protects multiple domain names (domain.com, newdomain.org, otherdomain.com) under one certificate. You can add/edit/ or delete SANs throughout the life cycle of your multi-domain certificate.
A multi-domain wildcard SSL certificate combines the features of a wildcard SSL certificate and a multi-domain certificate into one. It is designed to secure unlimited subdomains under multiple domains. During generation, the Common Name has to be a regular domain (www.domain.com) and the SAN fields can be your wildcard entries.
