What Is SSL

The Importance of SSL Certificates: Everything You Need to Know

Have you ever noticed a little "s" at the beginning of a website URL and wondered what it meant? That little "s" stands for security, indicating that your connection to the website is encrypted and your data is safe. This is made possible by SSL (Secure Sockets Layer) certificates.

But where did SSL certificates come from, and why are they so crucial? Let's explore the world of SSL certificates to find out.

What is an SSL Certificate?

An SSL certificate is a small data file that creates a secure, encrypted connection between a web server and a browser. This ensures that all communication between the two remains private and protected.

The Different Types of SSL Certificates

Organization Validated (OV SSL) Certificate

The OV SSL certificate verifies both the organization and domain ownership, providing a medium level of encryption. To obtain this certificate, the Certificate Authority (CA) verifies the legality and ownership of the organization and then displays a small green padlock with the company name in the URL bar. This is a good option for those who want moderate encryption but may not have the resources for an EV SSL certificate.

Domain Validation (DV) Certificate

The DV certificate offers a lower level of encryption, indicated by a green padlock next to the URL. Its validation process is quick, requiring only a few documents from the company. However, unlike OV and EV SSL certificates, a DV certificate does not secure subdomains.

The CA verifies a DV certificate by adding a DNS record to the submitted domain, confirming the applicant's ownership but not vetting any identity data. Though not as secure as other SSL certificates, a DV certificate is still a viable option for businesses on a budget.

Wildcard SSL Certificates

Wildcard SSL certificates fall under the category of "domain and subdomain" and can cover multiple subdomains with one certificate. For example, a Wildcard SSL for example.com can also be used for mail.example.com and blog.example.com. This option is more cost-effective than obtaining individual certificates for each subdomain.

Unified Communications (UCC) SSL Certificate

Also known as multi-domain SSL certificates, UCCs allow for multiple domain names to be covered by one certificate. Originally designed for communication between a single server and browser, UCCs can now include multiple domains owned by the same individual or organization. These certificates display as an EV SSL if configured to show the green text, padlock, and home country, with the only difference being the number of domain names included.

A UCC can cover up to 100 domain names and can add or remove names using the Subject Alternative Name (SAN) feature. For example, www.domain.co.uk, www.domain.com, mail.example.com, and checkout.example.com can all be covered under one UCC.

Single Domain SSL Certificate

A Single Domain SSL protects only one domain and cannot be used for subdomains or different domains. For instance, if you purchase a certificate for example.com, it cannot be used for blog.example.com or 2ndexample.com.

How to Obtain an SSL Certificate

The first step in obtaining an SSL certificate is determining what type is necessary for your website. For most websites, a standard SSL certificate will be sufficient. However, companies in regulated industries may need to consult with their IT team to ensure compliance with specific requirements.

The cost of an SSL certificate can vary, with options for free certificates or custom certificates with a monthly fee. Let's Encrypt offers free certificates, but it's advisable to have someone with technical knowledge assist with the setup. These certificates expire every 90 days, so it's essential to keep them up to date.

In conclusion, an SSL certificate is a critical aspect of website security and privacy. By understanding the different types available and their purposes, you can make an informed decision on which certificate is best for your website. Keep your website and visitors safe with a trustworthy SSL certificate.

Why SSL Certificates are Vital for Website Security

As a website owner, you are likely familiar with the term SSL certificate and its importance in securing your website. Many content management systems, including HubSpot's free CMS, offer a complimentary SSL certificate to help you protect your site.

Simply having an SSL certificate, though, is not enough. When it comes to making a decision, it is crucial to consider the certificate's validity period. Most standard SSL certificates, which you can purchase, are valid for one to two years. However, more advanced options are available that offer longer validity periods.

But why is having an SSL certificate necessary for your website? Let's explore the potential benefits for your site's SEO. Imagine two websites with similar content, one with SSL enabled and the other without. The site with SSL encryption is likely to receive a slight boost in search engine rankings due to its secure connection. This highlights that having SSL enabled on all your website's pages can have a positive impact on your SEO efforts.
