Many businesses manage multiple domains, and they each need reliable security to protect data and user interactions. Multi Domain SSL certificates simplify this process by enabling organizations to secure multiple domains and subdomains under a single certificate.
Multi Domain SSL streamlines security management and reduces costs and administrative overhead. Let’s look at what Multi Domain SSL is, why it matters, and how to implement it across your organization.
Introduction to Multi Domain SSL
Multi Domain SSL makes securing individual domains with separate SSL certificates easier by securing multiple domains with a single certificate.
A Multi Domain SSL (Secure Sockets Layer) certificate is a unique type of SSL certificate that allows multiple domains or subdomains to be secured under one umbrella certificate. Also known as a multi domain certificate or SAN certificate (Subject Alternative Name certificate), it’s an efficient solution for companies that operate multiple domains because it eliminates the need for separate certificates for each domain or subdomain.
For businesses managing multiple online properties, securing each site individually can quickly become time-consuming and costly. Multi Domain SSL certificates offer a streamlined, cost-effective solution to simplify security by consolidating all domain security into a single certificate.
How Multi Domain SSL Certificates Work
Multi Domain SSL certificates cover a range of domains under one certificate, allowing for scalable web security. Here’s a look at how these certificates secure multiple domains and subdomains.
Certificate Structure
Multi Domain SSL certificates accommodate multiple domains by using Subject Alternative Names (SANs). SANs are additional fields within the SSL certificate that specify each domain or subdomain covered under the certificate. This configuration enables a single certificate to protect multiple URLs, which can include unrelated domains, subdomains, or even IP addresses.
Domains and Subdomains
One of the core strengths of Multi Domain SSL is its flexibility in managing various web properties. A single certificate can secure primary domains as well as related subdomains.
For example, a business could secure company.com, blog.company.com, and shop.company.com under the same certificate. This flexibility simplifies security management for businesses with a diverse range of domains or subdomains under their control.
Key Benefits of Multi Domain SSL
Choosing a Multi Domain SSL certificate comes with a variety of benefits. From cost savings to improved security, here are a few reasons why Multi Domain SSL certificates are beneficial for businesses with multiple domains.
Cost Efficiency
Purchasing individual SSL certificates for multiple domains can be expensive, especially for businesses managing a large portfolio of websites. Multi Domain SSL certificates offer a cost-efficient alternative by allowing multiple domains to be secured under one certificate, reducing the overall SSL investment.
Simplified Management
Managing individual certificates for numerous domains can be challenging, especially for larger organizations. With Multi Domain SSL, administrators have a single certificate to manage, reducing the time spent on renewals, updates, and other maintenance tasks.
Enhanced Security
Multi Domain SSL certificates provide the same high level of encryption and security across all listed domains, ensuring that users are safe when interacting with any site under the certificate’s protection.
Types of Multi Domain SSL Certificates
There are different types of Multi Domain SSL certificates, each tailored to specific organizational needs. Here’s an overview of the main types of Multi Domain SSL certificates and their uses.
Standard Multi Domain SSL
A Standard Multi Domain SSL certificate is used to secure several distinct domains. For example, a company could secure company.com, company.org, and company.net under one standard multi domain certificate. It’s ideal for businesses that need to secure a specific number of unique domains without subdomain coverage.
Wildcard Multi Domain SSL
For organizations that require coverage for both multiple domains and their associated subdomains, a Wildcard Multi Domain SSL certificate is a good solution. By supporting wildcard entries (ex: something.company.com), this certificate can cover all subdomains associated with each domain, offering a broader scope of protection.
EV Multi Domain SSL
An Extended Validation (EV) Multi Domain SSL certificate is the highest level of SSL certificate available. It provides added assurance to users by displaying a green address bar or organization name in the browser, signaling enhanced security and trustworthiness. This certificate is ideal for businesses that handle sensitive data or wish to convey a high level of trust.
Choosing the Right Multi Domain SSL for Your Needs
Selecting the right SSL certificate depends on an organization’s unique needs. Here are a few things to consider when selecting a Multi Domain SSL for your company.
Assess Your Domain Needs
Select the appropriate type of Multi Domain SSL certificate by assessing your organization’s needs. Consider the number of domains and subdomains you need to secure and the level of trust you want to convey to your users. For example, if you only have a few main domains, a Standard Multi Domain SSL may suffice. For sites handling sensitive information, an EV Multi Domain SSL could be worth the investment.
Consider Compatibility and Renewal
Your chosen certificate should be compatible with all major browsers and devices to avoid compatibility issues for users. Additionally, consider setting up reminders for certificate renewals to prevent unexpected expirations, which can impact website security and user trust.
