SSL Certificate and its Types
SSL or Secure Socket Layer Certificate helps strengthen the security of a website by creating an encryption channel for secure data transfers. Primarily, it establishes a communication channel between the server and the end-user’s browser to maintain data integrity and confidentiality. It uses an SHA 256-bit encryption algorithm for generating the secure pipeline.
An SSL Certificate only gets issued by a Certificate Authority after complete validation of the domain ownership and legitimacy of the organization. And once it gets installed on the server, it instantly boosts the website's security as well as reputation. The HTTPS you see in any website’s URL is only due to an SSL Certificate.
With the advancement in security procedures and policies, browsers check the authenticity and validity of SSL certificates before starting a session. An SSL Handshake process takes place in milliseconds between the web server and the browser. Firstly, the browser sends the connection request to a server and, in return, receives a copy of the SSL certificate. Further, the browser validates the SSL details and confirms to the web server that it wants or does not want to establish a session. If everything goes right, an encrypted connection gets established.
Furthermore, SSL Certificates are available in different types, which get categorized based on validation level and domain coverage. Under the validation level, you can obtain Domain Validated, Organization Validated, and Extended Validation SSL Certificates. And the domain coverage category includes Single Domain, Multi-Domain, Wildcard, and Multi-Domain Wildcard SSL Certificate. Both validation level and domain coverage are available in combination. For instance, you can purchase an Organization Validated Multi-Domain SSL Certificate.
To get more specific about your requirement, you must thoroughly understand each type.
Domain Validated SSL Certificate
To avail of a DV SSL certificate, you only need to prove domain ownership to the CA. And after its issuance, you can use it for websites displaying information, such as blog sites.
Organization Validated SSL Certificate
To obtain an OV SSL certificate, you must be an organization situated at a physical location. After validating your company details, CA will issue you an OV SSL certificate, which you can use for securing sensitive data, such as login credentials.
Extended Validated SSL Certificate
EV SSL certificates only get issued to organizations with a minimum of three years of operability. And it's the only digital certificate that aligns with PCI-DSS, HIPPA, and HITECH standards.
Other common SSL Certificate Types
- Single Domain SSL Certificate (Secures only one WWW or non-WWW primary domain)
- Multi-Domain SSL Certificate (Allows to enable HTTPS on 250 different main domains)
- Wildcard SSL Certificate (Enables to secure one main domain and all its sub-domains)
- Multi-Domain Wildcard SSL Certificate (Secures up to 250 different domains and their unlimited sub-domains)
A Seamless Procedure to Enable HTTPS in Browser
Step 3: Install the SSL Certificate
Lastly, you must install the SSL Certificate on the web/exchange server. To start its installation, export it from the browser to the local machine storage and follow the relevant procedure according to the server type and operating system.
However, while installing an SSL Certificate, always remember to enable automatic renewal, as it would help prevent disabling an encrypted channel. Also, create a backup server to maintain the data records in case of unexpected malicious activity. Additionally, enable HTTPS forcing to navigate all your visitors to your authentic and secure website, guaranteeing data integrity.
How to Choose the Right SSL Certificate?
To choose the right SSL Certificate, you must focus on three primary aspects – Validation Type, Number of Domains/Sub-Domains, and Certificate Authority.

Importance of SSL Certificate
Business/Website Reputation and Sales
When you install an SSL certificate, websites display HTTPS with the URL and padlock symbol in the address bar. And whenever visitors view all such trust signs, they understand that they are navigating on a CA-verified domain and their data is secure throughout the session. As a result, people prefer your website to avail services or buy products, which increases the incoming traffic, sales, and overall revenue.
Instant Website Security
With an SSL certificate, you can instantly secure the data transmissions. SSL certificates are available at different validation levels and take a minimum of 15 minutes and a maximum of 5 days to get issued. In such a minimal time, you can configure SHA 256-bit data encrypted channel between the web server and the client's web browser. It will help you assure data integrity to customers and align with mandatory security standards defined by browsers.
Nowadays, browsers only trust websites with SSL certificates and allow only their access to the end-user. Before starting a session with any web server, the browser checks the validity and authenticity of its SSL certificate. Therefore, if you install an SSL Certificate for your domain or IP, the browser will treat it legitimately, and all the security warnings will be eliminated. And all your current and new customers will have a smooth site experience.
Boost SEO Ranking
Most search engines consider SSL as a ranking metric to encourage and maintain digital security. Websites with valid SSL certificates get priority as compared to non-secure websites. Whenever the end-user searches for some services or product, search engines display the results, including sites with SSL certificates only. Hence, utilizing an SSL certificate plays a primary role in increasing the website ranking across multiple search engines and increasing reach to the target audience.
Frequently Asked Questions

SSL Certificate is mandatory by search engines and browsers to provide end-users a secure environment and prevent malicious activities. Moreover, it encrypts the data transfer channel between two systems, particularly between the browser and web server, to assure data integrity.
A domain-validated SSL certificate is a reliable choice for a blogging website. It gets issued within minutes, and as no personal information is processed, you must prefer it. Further, if you only need to protect only one domain, then a Single-Domain SSL certificate is acceptable; otherwise, you can select according to your requirements.
For an e-commerce store, an Extended Validated SSL certificate is a perfect choice. It complies with all PCI-DSS standards to offer a secure payment gateway for credit cards, debit cards, digital wallets, and other banking options.
You must purchase a Multi-Domain SSL certificate to secure numerous primary domains. It will aid you in enabling HTTPS on 250 websites simultaneously. With the first buy, you can protect three domains, and later you can buy SAN certificates at a cheap price to protect more 247 domain names.
SSL Certificate installs on a web server. When someone tries to access a website, the browser reaches out to the appropriate server and requests its SSL certificate. Then, the server sends a copy of the digital certificate. And the browser verifies its validity and details. If the SSL certificate seems correct, the browser acknowledges the server, and an encrypted communication pipeline gets built between them.
SSL and TLS (Transport Security Layer) are the same, providing similar functionality to transmit data between systems securely. Moreover, TLS is an advanced version of SSL, which uses a refined and more robust encryption mechanism.
All types of SSL certificates are best in their way. It entirely depends upon your needs to determine which SSL certificate would suit you. Before selecting any of them, you must understand all the types of SSL certificates.
If your SSL certificate expires, browsers will warn your visitors whenever they open the website. And all data transfers will take place in the original format. Hence, you should always remember the expiration date and renew the certificate before it, or you must automate certificate renewal.
You must open the website on a browser to check the successful installation of an SSL/TLS certificate. If it shows you HTTPS and a padlock icon in the address bar/URL, then SSL is working correctly. And the other method is to use an SSL Checker Tool.
All search engines have made SSL certificates mandatory for websites. And while inspecting the site content, they also analyze the web security. If the SSL certificate is present, it boosts the ranking; otherwise downgrades it to protect end-users from malicious threats.
