Understanding SAN Certificates : Benefits & How They Work

SAN Certificates or Subject Alternative Name Certificates are SSL Certificates that secure multiple domains or subdomains under a single SSL Certificate. This is in contrast to a single-domain SSL Certificate which only protects one specific domain. This makes SAN Certificates incredibly versatile and cost-effective for businesses with complex web infrastructures.

SAN Certificates offer a streamlined solution for managing multiple websites or domains. Instead of purchasing and managing several individual SSL Certificates you can use a single SAN Certificate. This simplifies management and reduces overall costs. SAN Certificates provide a robust security solution for larger organizations.

How SAN Certificates Work

A SAN Certificate works by listing all the domains and subdomains it protects within its digital identity. This list is embedded within the Certificate itself. When a user accesses any of the listed domains their browser checks the Certificate to verify its authenticity and validity. If the Certificate is valid the browser establishes a secure connection.

The browser verifies the Certificate by checking the digital signature of a trusted Certificate Authority like Trustico® and confirms the Certificate's authenticity ensuring the user's connection is secure. If the Certificate is invalid or expired the browser displays a warning message preventing the user from accessing the website.

Benefits of Using SAN Certificates

One major benefit is cost savings. Purchasing multiple SSL Certificates can be expensive. A single SAN Certificate covering multiple domains is significantly more economical. It also simplifies management as you only need to renew and manage one Certificate instead of many.

Improved security is another key advantage. With all your domains protected by a single Certificate you benefit from consistent and robust security across your entire online presence. Using a single Certificate reduces the chances of human error when managing multiple Certificates. Choosing a reputable Certificate Authority such as Trustico® further enhances your security.

Choosing the Right SAN Certificate

When selecting a SAN Certificate consider the number of domains you need to protect. Different SAN Certificates have varying limits on the number of domains they can secure. You should also consider the validation type. Different validation types such as Domain Validation (DV) or Extended Validation (EV) offer different levels of security and trust.

The Certificate Authority is another crucial factor. Reputable Certificate Authorities like Trustico® provide high-quality Certificates backed by strong security practices and exceptional customer support.
