Anytime your website visitors access your site, data gets transferred from server to server before it reaches its destination. As the internet evolves, so do its users (and those who wish to exploit them). Without a secure connection, that transmitted data is at risk. How do you protect your users, prospects, and customers as they browse? That's where SSLs come in. 

What Is an SSL?

Secure Sockets Layer (SSL) is a security protocol that creates an encrypted link between a web server and a web browser. It ensures that all transferred data remains confidential.

You've seen a lock icon next to the URL in your address bar when you go to certain sites, right? That means the site is protected by SSL.

Your site should have SSL, especially if you use your site to process financial transactions. It will protect you from data breaches, and it gives visitors a good reason to trust you with sensitive information. It improves your rankings in search results as well.

But SSL certificates can be expensive if you don't know where to look or what you're buying.

How Much Is an SSL?

The cost of your SSL can range from free to hundreds of dollars, depending on the level of security you require. Here are the types of SSLs ranging from least secure to most secure (and, generally, lowest to highest in price): 

  • Domain Validated (DV) Certificates - For sites, such as blogs or small business websites, that don't exchange any customer information.
  • Organization Validated (OV) Certificates - For sites, such as business websites with forms and lead capture capabilities, that don't exchange sensitive customer information. 
  • Extended Validated (EV) Certificates - Highest level of security, capable of handling sensitive information such as financial transactions.

How to Get an SSL Certificate

Once you choose the type of certificate you require, you can then shop around for Certificate Issuers that offer SSLs at that level. Getting your SSL amounts to the following steps: 

  1. Ensuring your WHOIS record is updated and matches what you're submitting to the Certificate Issuer. 
  2. Generating the Certificate Signing Request (CSR) on your server. (Your hosting company can help with this.)
  3. Submitting this to the Certificate Issuer to validate your domain. 
  4. Installing the certificate they provide you once the process is complete.
