SSL certificates – the “s” in “https://,” – is responsible for making sure that the data transmitted among them is safe and private by connecting a cryptographic key to the site owner’s details and creating an encrypted link between the web server and browser. While there are several types of SSL certificates available on the market (either from a web hosting provider or a third-party service, depending on your site’s needs), it’s important to learn about them before buying.

In this article, we’ll give a brief overview of SSL certificates – what they are, the types of SSL certificates that are offered, how to be safe with them, and how they work. Then, we’ll uncover 10 of the best SSL certificate providers to buy cheap SSL certificates for your online business. Afterwards, we’ll conclude with what factors to look for when considering which SSL certificates to use.

What is an SSL Certificate?

When starting an online business, you might come across something called a Secure Sockets Layer (SSL) certificate. This certificate helps your website stay secure, even as you run an eCommerce site (whether you’re selling products or services). So, whenever you’re running two machines, the certificate should be able to encrypt the data stream that’s going between those machines.

Nowadays, data encryption is needed, so that every eCommerce transaction made on a site are secure. Therefore, investing in a recognized SSL certificate allows you to manage your site’s data encryption.

This is especially important, since search engines like Google are very strict with which websites are deemed safe, and which ones are deemed fraudulent. So, if you don’t invest in an SSL certificate, you’re running the risk of the following:

  • Your site will be vulnerable to hackers and cybercriminals.
  • Your site will get penalized by search engines like Google.
  • Consumers will not trust your site with their time and their money.

Now, while there’s a significant need for SSL certificates to encrypt and protect data, there’s no guarantee that the server will work for you, or if a certain certificate is worth investing in. Therefore, many companies use to work with a trusted third party – a so-called certificate authority – to get issued the right SSL certificate, while being charged a fee for it.

Types of SSL Certificates

Now, it’s important to note that not all SSL certificates are created equal. In fact, SSL certificates are categorized into 3 categories:

  • A Domain-Validated (DV) Certificate is ideal for internal projects, but not so for the open web.
    • Either cheap or free of charge
    • Caution must be exercised whenever websites use this certificate
  • An Organization-Validated (OV) Certificate is for businesses and organizations that already have some form of governing authentication, which makes verification simple.
    • Organizations are asked to provide proof of validation
    • This is a certificate that’s only for a commercial website
  • An Extended Validation (EV) Certificate is the most-trusted level of SSL certificates, since it’s thorough and strict in its operations.
    • Verification is uncommon with this certificate
    • Identifying the legal entity that controls the site must be determined and published before this certificate is issued
    • Most modern web browsers show a green Uniform Resource Locator (URL) to indicate the use of an EV certificate.

As you keep in mind the three categories of SSL certificates, you should also know that such certificates come in two variations:

  • A single-domain certificate is used for a single website.
    • Protects that one site
    • Cheaper, compared to the wildcard certificate
    • Effective, if you want an EV certificate (This is because of how and where it’s used)
  • A wildcard certificate is for when you want to protect multiple sub-domains.
    • The “cousin” to the single-domain certificate
    • More expensive than its cousin (though, a volume discount might be given to you, depending on the provider that you buy the certificate from)

How To Ensure Web Security

Having an SSL certificate should ensure that your site is safe for people to visit and use. However, even as you use an SSL certificate (no matter the type and variant), you’ll still keep to ensure that your site has the 3 visual signs of a secure site:

  • The URL of your website in the browser address bar should start with either “http” or “https.” Though, the “s” in “https” indicates that the site is secure.
  • The address bar should also have a close lock/padlock icon along with the URL.
  • An SSL site seal on a website means that a legitimate CA had verified the site, and issued the SSL certificate.

How SSL Works

Investing in an SSL certificate for your website is more than just making sure that your website is secure. In fact, there’s a process that goes into establishing an SSL connection between the web browser and the server – this process is called the “SSL Handshake.”

In the SSL Handshake, there are three keys used to establish a connection – public, private and session. And, it’s with this connection that’s encrypted with a public key, which can, in turn, be decrypted only with a private key. That means that an encrypted private key can be decrypted only with a public key.

With that said, here’s how the SSL Handshake works:

  • First, the browser connects to the secure website, and asks for server identity.
  • The server then sends you its SSL Certificate copy with its public key.
  • Then, the browser verifies that the SSL certificate isn’t expired or revoked, and came from a trusted CA.
  • When given the “all-clear,” the browser creates, encrypts, and sends back a session key by using the server’s public key.
  • The receiving server decrypts the session key with its private key.
  • Then, the receiving server acknowledges the session key.
  • The server can then start encrypting the session key.
  • By now, the transmitted data between browser and server is encrypted with the session key.

Therefore, you’ll need to consider the factors before picking and purchasing the right SSL certificate provider. Such factors include:

  • The trial period, when you can test your purchase, and determine whether or not it’s a good investment
  • How compatible the SSL certificate is to your browser compatibility (especially if you’re still running Windows 7 or older release on your computer)
  • The timeframe that the certificate is issued (even when there are deadlines involved)
  • How much you trust the provider, to ensure that your certificate can match your website’s needs with top-notch security and 100% trust. If the certificate does a good job in ensuring safe financial transactions, for example, then it’s warranted as a trustworthy source.
  • How the provider shows off its Trust site seal to the public. Thus, customers can safely explore a certain website
  • Equipped with an SSL support team, whenever situations with the SSL certificate are critical
  • The refund policy of the chosen SSL certificate provider, if a business isn’t satisfied with the certificate that they’ve purchased – While situations like this are rare, it’s better for a business to be safe than sorry, when investing in an SSL certificate.
