Multi-Domain SSL: Everything You Need to Know
There are many aspects of SSL certificates that are important to keep in mind at all times. A single ssl certificate for multiple domains is very important and this is the reason why you need to consider if you can get one certificate for multiple domains.
What Are Multi-Domain Certificates?
A Multi-Domain SSL Certificate (also known as a SAN or UCC certificate) is a type of SSL certificate that allows you to secure multiple domains and subdomains with a single certificate. This means you can manage the encryption for several unique domain names without needing separate SSL certificates for each. For example, a single Multi-Domain SSL can cover:
- www.example.com
- shop.example.com
- www.example2.com
This versatility makes it a popular choice for businesses managing multiple websites under one umbrella.
Importance of Multi-Domain Certificates
Cost Efficiency
Purchasing separate SSL certificates for multiple domains can quickly become expensive. A Multi-Domain SSL offers a more budget-friendly alternative.
Simplified Management
Instead of tracking multiple expiration dates and configurations, you manage encryption for all domains with one certificate.
Trust and Security
Ensures robust encryption across all domains, protecting sensitive information like passwords, credit card details, and personal data
SEO Benefits
Secure domains rank higher in search engine results. A Multi-Domain SSL ensures that all your websites are HTTPS-secured, boosting SEO performance.
What Is It Used For?
Multi-Domain SSL Certificates are ideal for:
Businesses with multiple websites: Companies with several brands or projects often use one certificate to secure multiple domains.
Organizations with a global presence: Businesses managing different geographic sites under unique domains.
Service providers and SaaS platforms: To secure customer portals and dashboards across various domains.
Example use cases:
- E-commerce sites with multiple storefronts.
- Hosting providers offering secure domains to clients.
- Educational institutions managing separate domains for departments.
- How to Get a Multi-Domain SSL Certificate
Acquiring a Multi-Domain SSL Certificate is straightforward:
Choose a Trusted SSL Provider
Select a reliable Certificate Authority (CA) like DigiCert, Sectigo, or Thawte, which offers Multi-Domain SSL options. This is ideal for one certificate for multiple domains or single ssl certificate for multiple domains.
Determine Your Domain Needs
List all the domains you need to secure under the certificate. Most providers allow you to add more domains later if needed.
Generate a Certificate Signing Request (CSR)
This file contains your server's public key and domain details. It’s created on your web hosting server or control panel.
Complete Validation
Depending on the level of SSL you choose (DV, OV, EV), you'll need to provide specific documentation to verify your domain ownership or business identity.
Install the Certificate
After issuance, install the SSL certificate on your server. Most providers offer guides or direct support for this step.
Final Thoughts
A Multi-Domain SSL Certificate is a practical, cost-effective solution for securing multiple websites under one umbrella. Whether you manage several e-commerce sites or operate a global business, these certificates streamline security while providing peace of mind. By opting for one SSL certificate for multiple domains, you simplify management, reduce costs, and ensure robust encryption for all your digital assets.
