Investing in SSL

Nowadays, people are earnest about the privacy level of their accounts and identification online. As a website owner, you must provide them with certain protection to visit your website and make purchases. Due to the Covid-19 pandemic in 2020-2021, many businesses went remote, and they have been connecting with their clients and colleagues online.

Online eCommerce is growing each day, and in the United States alone, it is expected to surpass $740 billion by 2023. Now, you need to ask yourself, is it worth investing in your website’s security by installing an SSL certificate, or would you rather not do anything?


What is SSL?

SSL certificates are a part of the movement that keeps the internet safe and secure. It encrypts the data while it is being transferred from between two computers, servers, or clients. SSL certificates protect your customer’s data, preventing hackers from accessing them or modifying them for their criminal behavior. As mentioned above, SSL is a known security protocol worldwide. When visitors see it on your website, they feel somewhat protected and know that their information is protected on your website.


Types of SSL Certificate

Different types of SSL certificates have different encryption and validation. Let’s talk about them.


OV SSL – Organization Validated SSL

OV SSL certificate validates your whole organization as well as your website. The level of OV SSL certificate has a close to medium level of encryption and must be obtained in two steps. First and foremost, the CA (Certificate Authority) must verify who is the owner of the organization and is the operation legal.

Whenever users visit your website, they would see a green lock with the company’s name following it. This type of certificate is perfect for company’s who would like their companies to be validated.


EV SSL – Extended Validation SSL

EV SSL verifies your business, country and gives you HTTPS as well as a green lock that displays in the browser’s address bar. Extended Validation SSL Certificate is considered to be the most expensive SSL that you can obtain. It thoroughly verifies what you do and guarantees users that the website they are viewing and will be doing business with is completely legitimate. They don’t have to worry about using their bank details to make a transaction on the said website.


DV SSL – Domain Validation SSL

Domain Validation SSL is considered to have low-level encryption, and it will show a green lock in the address bar next to your website’s URL. DV SSL is the fastest SSL certificate that you can obtain, and it only requires a few pieces of documentation for its validation.

To get the verification done, you are going to need to add a DNS to CA. The Certificate Authority then will review the applicant and make sure it is indeed the owner who is requesting the validation. Perhaps the biggest difference between DV and EV SSL is that CA won’t guarantee any identity. Therefore, you won’t know who will be receiving your information.

If you are part of a website that cannot afford any high-level SSL certificate, a Domain Validation SSL is probably enough.


Single Domain SSL

As you can probably tell by its name, a Single Domain SSL protects one domain. Therefore, if you have subdomains on your main domain, this type of SSL certificate won’t be able to protect your subdomains. For example, if you purchase this type of SSL for test.com, it won’t give you a certificate or protection for blog.test.com.


Wildcard SSL

Unlike Single Domain SSL, Wildcard will protect both your main domain as well as its subdomains. For example, if you add it to test.com and have a subdomain of blog.test.com, it will add an SSL certificate to the subdomain as well. A Wildcard SSL is the cheapest certificate for a domain name that has a few subdomains.


UCC SSL – Unified Communications Certificate

Unified Communications Certificate allows the owner to have more than one domain name allocated to the SSL certificate. It can add SSL to multiple websites as long as the owner of those websites is one organization.

UCC SSL certification will display a lock in the address bar, and it can be configured to display the green text as well. This type of SSL certificate can cover up to 100 domain names.
