Different Types Of SSL Certificates

By Surya

SSL is abbreviated as Secured Socket Layers. SSL certificates are necessary for a website because they encrypt the communication between the server and the client. Also, the transfer of most sensitive details such as personal details, login credentials, etc., are encrypted by the SSL certificates.

To identify if the website is installed with an SSL Certificate, it can be easily identified in the address bar of the website in the browser.  The tune icon (aka) padlock which will show “connection is secure” when you click it in the address bar – an clear identification of a secured website.

Also once the SSL is installed, an SSL handshake will happen which will ensure all your data are passed with encryption.

Example of URL with SSL & Without SSL:

Not Secure: http://baringwitness.org (Without SSL)

Secure: https://www.seekahost.com (With SSL)

Purpose of SSL Certificate:

If the website is attacked by malicious activities or spammers, the most sensitive information will be stolen such as Logins, Forms (Used for collecting personal data), & the card transactions.

Key benefits of an SSL certificate:

• Data Encryption: Protects information transmitted between your website and users.
• Website Authentication: Verifies your website’s identity, preventing phishing attacks.
• Trust Building: Inspires confidence in visitors, increasing credibility.
• Search Engine Ranking: Improves your website’s search engine visibility.
• Compliance: Meets industry standards and regulations for data protection.

Without SSL, your website is vulnerable to attacks, and your customers’ sensitive information is at risk.

Four types of SSL Certificates:

Single – Domain SSL Certificates

The Single – Domain SSL Certificate is a type of SSL certificate which is applicable for only one website. Even if you have sub-domains, it will not be applicable to them. This single-domain SSL certificate secures each and every page of the website. This type of certificate is most useful for bloggers, personal websites, etc.

Multi-Domain SSL Certificates

Multi-Domain SSL Certificate helps you to secure and encrypt more than one single website under a single certificate. This type of certificate is widely used in large organizations. The added advantage is, this type of SSL certificate is valid for the subdomains too.

Wildcard SSL Certificates

This Wildcard SSL certificates can be used to secure a single website having unlimited subdomains. Thus, having multiple subdomains under a single primary domain is applicable for adding the Wildcard SSL certificates.

Unified Communications SSL Certificates

This is also much similar to the Multi-Domain SSL Certificate, by which it can secure more domains and it’s subdomains under a single certificate. However, it is used only in unique environments. It uses a SAN (Subject Alternative Name) extension for securing multiple domains.
