What is SSL and SSL Certificate?

Secured Socket Layer (SSL) is the technology that makes sure data between two machines (in our case – a browser and a server) is transmitted securely in an encrypted connection (HTTPS).

An SSL Certificate is a digital certificate that confirms the identity of a website.

To implement SSL on your website, you will need to get an SSL Certificate from a SSL Certificate Provider, aka. Certification Authority.

How SSL connection works

The following diagram shows how data is transferred through an SSL connection.

This is how SSL works
How SSL works
  1. A user access a HTTPS website
  2. User's browser requests a secure SSL connection from the server
  3. The server responds with a valid SSL certificate
  4. The secure connection is now established
  5. Data is encrypted and transferred

How can I tell if a website has SSL connection?

The use of an SSL Certificate on a website is usually indicated by a padlock icon on web browsers and the website address will show HTTPS. In some cases, a green address bar is shown.

If a SSL certificate is not recognized by the browser (or it does not pass certain checks), the browser will display a warning to the visitor.

Things to Know Before Purchasing a SSL Certificate

Implementing HTTPS for Better Site Security

There are a number of ways you can get protected an SSL certificate and implement HTTPS to your websites. These include using a free one by Let's Encrypt, making use of Cloudflare's automatic SSL coverage, or even buying one depending on your requirements.

To make sure that your SSL purchase process goes smoothly, we recommend that you get the following things ready.

  • A unique website IP address
  • A certificate signing request (CSR)
  • Updated and correct WHOIS record
  • Validation documents for your business/organization

Types of SSL certificate

There are three types of SSL certificate – Domain Validated (DV), Organizational Validated (OV), and Extended Validated (EV).

Domain Validated (DV)

  • Verification – DV only verifies that the applicant is the registrant of the domain.
  • Implementation time & costs – It takes few minutes to few hours. The fee is minimal.
  • Price range – Starting at $6 per year.
  • Ideal for – Suitable for small websites or blogs.

Organizational Validated (OV)

  • Verification – OV verifies the ownership of the domain including full company name and address details.
  • Implementation time & costs – It might take a few days. The fee is higher than DV.
  • Price range – Starting at $20 per year.
  • Ideal for – Suitable for organizations and medium-sized businesses.

Extended Validated (EV)

  • Verification – EV requires an extensive validation of the business that turns the address bar to green.
  • Implementation time & costs – It might take up to weeks. EV is the most expensive SSL certificate.
  • Price range – Starting at $70 per year.
  • Ideal for – Suitable for websites that conduct financial transactions.

Despite the types of validation, all the certificates are having the same levels of data encryption. The only difference is the assurance about the identity of the business behind the website. You can compare the costs and features of different types of SSL certificates at


Here are examples of different types of validation.

Example of SSL certificates in browser has the Organization Validated (OV) SSL validation – The address bar shows “Secure”. Telling visitors that the connection between the browser and the website is encrypted.
Extended SSL validation is using Extended Validated (EV) SSL. Company with EV SSL went through extensive validation that confirms that the business entity is legal. In some browsers, the company name will be shown on the address bar in green color.

Are Cheap SSL Deals Okay?

Example –'s Basic Certificate comes with automated validation (big time-saver), 2048+ BIT SHA2 encryption, and 99% browser compatibility – these features should be more than enough for a small business website or blog.

“Branded” SSL vs Cheap SSL

A cheap SSL offers the same security as the expensive ones. So in most cases, there is no need to opt for a “branded”SSL certificate – which be expensive.

The only time that you should really consider purchasing an expensive SSL certificate is if you’re a big eCommerce company that’s looking to perform transactions on a device that uses its own proprietary software.

Larger businesses should also opt for a “branded” SSL certificate as part of your due diligence process. The reason for this is that the companies issuing these certificates often have reputable track records which might be necessary for selection justification.

Frequent Asked Questions

Why do we need an SSL certificate

The primary reason for using an SSL certificate is to make sure the data sent across the Internet become encrypted. So, everyone else can't read the information except for the server you are sending the information to. This can prevent hackers and cyber-thieves from stealing your data.

How much does an SSL certificate cost?

The SSL certificate prices vary depending on the type of certificate and the number of domains you want to protect. A dedicated SSL certificate for a single domain starts at $5.88 per year. A wildcard SSL certificate that protects unlimited sub-domains starts at $70.88 per year. You can compare the costs and features of different SSL certificates here.

Do I need an SSL certificate for my website?

Yes, it's recommended to have an SSL certificate for your website. Search engines now label websites without SSL as “Non-secure” websites and that might impact your ranking. Also, having an SSL certificate can earn your visitors' trust because the visitors know their data is secure.

Is SSL certificate required for online store?

It's recommended to install an SSL certificate for your online store even though it's not compulsory. SSL certificate encrypts customer data, sensitive information, payment details, etc and keeps it protected during transfer. Besides securing the website, by installing an SSL certificate, it helps to gain customers' trust and encourage them for safe and secure online shopping.

What's the difference between a free SSL certificate and a paid SSL certificate?

There's no difference in security between a free SSL certificate and a paid SSL certificate. The major differences between both are in terms of the type of certificate, level of validation, support and warranty. For instance, free SSL certificates only come with Domain Validation (DV) and no warranty. On the other hand, a paid SSL certificate covers everything you required.

This is where different pricing also comes into play with SSL certificates. Warranties on paid SSL certificates can differ vastly – from as low as a few thousand dollars up to two million dollars (As far as we know, only DigiCert goes this high).

What SSL certificate do I need?

If you are running a small website or a blog, a DV certificate is good enough. If your website conducts financial transactions, it's best to go for an EV certificate that turns the address bar to green.

Is free SSL safe?

Yes, there's no risk of using a free SSL certificate. However, a free SSL certificate does have some shortcomings such as limited period, only offers domain validated, no support from the company, and no warranty. If you are running an online store, a free SSL certificate might not be a suitable choice.
