What’s an SSL Certificate?
For starters, an SSL certificate stands for Secure Socket Layer and it is basically a security protocol that protects communication between web browser and server. When a user sends requests to your server from the browser, the communication is protected from eavesdroppers who might want to intercept it for malicious reasons.
In other words, SSL can help you secure contentious data such as credit cards transactions, data transfers, login details, browsing data etc.
You might have noticed that some sites’ URLs start with “https” with a padlock sign while others start with “HTTP:”.
The difference is simple! HTTPS means that the site has been secured using SSL and vice versa.

The other essential benefit of using SSL comes in the shape of complying industry security standards. A great example of this is the Payment Card Industry Data Security Standards (PCI DSS). It is an organization founded in 2006 by major payment card brands like Visa, MasterCard, American Express, Discover etc. Their goal is to secure and manage online transactions through regulations for online merchants handling credit cards-installing an SSL certificate is one of the standards.
In fact, online merchants are supposed to fulfill a set of requirements set by the PCI SSC for SSL certificate installation including having strong private keys, strong cipher suites, using trusted SSL, securing card details etc.

Organization Validation Certificates :
In this type of SSL certificates, the validation is taken a notch higher in that the CA cross-checks the ownership of the domain along with other basic info about the organization requesting for the certificate e.g name, city, and country. The company info will be displayed in the certificates name.
EV Certificates :
The Extended Validation certificates otherwise known as EV SSL takes a stricter path before an organization is issued with the SSL.
The CA will verify the ownership, organization information, physical location, and legal aspects regarding an organization including if they are aware of the request made to them for the certificate.
As an indication, a green address bar is displayed along with the company’s name.
Based on the number of domains they can secure, Main types of SSL are:
