Secure Socket Layer (SSL) Certificate is an important tool every website owner should have if you want to build a website.

Why? Because it tells people and potential customers that your website is trustworthy and reputable and that your business is legitimate.

And more importantly, it means your website is safe to protect a customer’s’ sensitive data.

If you don’t have an SSL certificate, then you need to get one as soon as possible. More and more businesses are making sure that their website is SSL certified as search engines such as Google will flag those without one as being “Not secure”.

Google announced that starting in July 2018, Chrome browser will label all websites not using HTTPS encryption as “not secure”.

Convinced that you need an SSL certificate? Great! Before you go off and purchase one, there are few things that you need to consider, such as where to buy them and figuring out which SSL certificate is right for your website.

In this article, we’ll talk about the process of purchasing an SSL certificate and give you the list of the 10 best SSL certificate provider on the market.

Before you purchase SSL certificate

Before you go off and buy an SSL certificate for your website, there are a few things that you need to figure out. Namely, figuring out which type of SSL certificate is right for your business.

The major types of SSL certificates that you can get are:

  • Organizationally Validated (OV) SSL Certificate,
  • Extended Validation (EV) SSL Certificate 
  • Domain Validated (DV) SSL Certificate


Both Organizationally Validated (OV) SSL Certificate and Extended Validation (EV) SSL Certificate requires the SSL certificate issuer to check and verify information about the applicant’s business.

The main difference between OV and EV SSL certificates is that an EV requires an extensive validation of the applicant’s business to ensure that the applicant is not a spoofer, phisher, or any other type of illegal online business.

Generally, getting an EV certificate would be better for corporations, sole proprietors, government agencies, and basically any site that conducts financial transactions. OV SSL certificates, on the hand, is best suited for medium-sized businesses.

For Domain Validated (DV) SSL Certificate, it only verifies that the applicant who is buying the SSL certificate is the registrant of the website domain name that the SSL certificate will be attached to. If you’re a small website or a blog, a DV SSL certificate might suffice for the time being.

Depending on your business requirements, there are other SSL certificates options you can go for such as Single Domain certificate for protecting a single domain name, Wildcard SSL for sub-domain protection, SAN for multiple domains, and more.

Whichever type you choose, having an SSL certificate ensures that all of your customer’s data will be encrypted when they are transmitted between your website and the customer’s browser.

How to purchase an SSL certificate

When you’re ready to purchase or order an SSL certificate for your website, there are a few steps that you need to be aware.

In a nutshell, the process of ordering a certificate goes something like this:

  • Prepare your website by setting up your server and making sure your WHOIS record is correct (it should show the correct company name and address).
  • Next, you need to generate the certificate signing request (CSR) which is a block of encoded text that’s given to a Certificate Authority when applying for an SSL certificate.
  • Submit the CSR and any other other related details to the Certificate Authority.
  • Get your domain and company validated
  • Once you’ve received your issued certificate, you can go ahead and install it.

Things to get ready before buying an SSL certificate

To make sure that the process of buying an SSL certificate for your website goes smoothly, we recommend that you get the following things ready.

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


Some of it should be done naturally when you create a website but just double check so that you don’t have anything missing.

Should I go for cheap SSL certificate?

If you’re a small business or just starting out, getting a “brand name” or quality SSL certificate for your website can be expensive, especially when you try to renew as some companies tend to hike up the price once your SSL certificate expires.

The alternative is to go for cheap SSL certificates like GoDaddy or NameCheap.

Now, if you’re worried that using a cheaper SSL certificate means having less security than branded ones such as SSL.com or Network Solutions, then worry not. Unless you’re intending to conduct transactions on a device that doesn’t use a popular 3rd party browser, then a cheap SSL offers the same security as the more expensive ones.

If you’re going to conduct all your transaction on a web browser such as Chrome, Safari, IE, Firefox, etc., then you don’t really need to pay for an expensive certificate.

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.

In such cases, it’s better to go for a branded SSL certificate like Network Solutions because they will work across more devices. You should also check to make sure that whatever browser or app you’re targeting will recognize your SSL certificate vendor.
