What is a multi-domain SSL certificate?
Multi-domain SSL certificates , also known as Unified Communications (UCC) certificates or SAN (Subject Alternative Names) certificates , are digital security tools that allow you to protect multiple domain names and subdomains under a single certificate .
These certificates are ideal for organizations that operate multiple websites or online services under different domain names. For example, a company with domains such as 'company.mx', 'products.company.mx' (a website with its catalog) and 'services.company.com', can secure all of these sites with a single multi-domain SSL certificate . This solution not only simplifies managing the security of multiple domains, but is also more cost-effective and efficient than purchasing and managing multiple individual SSL certificates.
Multi-domain SSL certificates use the same level of encryption as a portugal business email list standard SSL certificate , ensuring that information transmitted between the server and the end user is encrypted and protected from malicious interception at all times.

Allows you to add or remove domain names as needed.
Reduce the complexity and time spent managing multiple SSL certificates.
It is cheaper than purchasing individual certificates for each domain or subdomain.
It offers the same level of encryption and security for all domains included in the certificate.
Differences between multi-domain SSL and SAN SSL
While similar, multi-domain SSL certificates and SAN SSL have several differences that you should consider when choosing between one solution or the other.
Purpose and Use: A multi-domain SSL certificate is specifically designed to secure multiple domains and subdomains under a single entity, while SAN SSLs are more flexible and can include multiple domain names and subdomains from different entities.
Flexibility: SAN SSL certificates offer greater flexibility to add or remove names as needed, which can be more limited with multi-domain SSL certificates.
Configuration and Management: SSL SAN management can be more complex due to its flexibility and the variety of names it can include.
Importance of web security and SSL certificates
Web security is crucial in the digital age. That is why SSL certificates play a leading role in protecting information transmitted between the server and the user , as they ensure that sensitive information, such as credit card details and personal data, is protected against unauthorized access.
