Cheap & Best Multidomain SSL Certificates in UK

Multi-domain SSL Certificates - What Makes Them Special?

Especially for commercial projects, it is often recommended to use more than one Top Level Domain (TLD) to ensure optimal reachability or to regionalize and specialize offers. In these cases, Multi-domain SSL certificates - also known as SAN certificates - can provide a unified and central encryption solution that can encompass up to several hundred internet addresses. This option can offer numerous benefits to users, making it highly attractive compared to individual SSL certificates for each domain.

How Do Multi-domain SSL Certificates Work?

For security reasons, it is essential today to protect an internet address with an SSL certificate. This process has been a necessary standard since 2015 to ensure secure data transmission to the server through encryption and is required by most browsers to access a website. Many commercial certificates only protect a single domain and do not include subdomains or other Uniform Resource Locators (URLs). In contrast, Multi-domain SSL certificates consolidate multiple internet addresses and can be installed on a single dedicated or virtual server as a collective instance, on a web hosting, or in multiple locations simultaneously.

Similar to simple SSL certificates, Multi-domain SSL certificates verify the accessed domain with each connection and then confirm its authenticity if it matches the request. Additionally, the communication uses the certificate for encrypting data transmission via HTTPS, ensuring that sensitive information is only sent and decrypted by the two endpoints. However, the so-called Single-Name and Multi-domain SSL certificates differ in that the latter contain an additional field called Subject Alternative Name Extension (SAN), an extension for alternative names. This field can include additional email addresses or IPs, as well as domains that are additionally verified during a query. This allows Multi-domain SSL certificates to be valid for transmitting data across multiple websites simultaneously.

What Are the Benefits of Multi-domain SSL Certificates?

There are other certificates that also cover more than one domain: the Wildcard certificates, which can only be used for a TLD and its subdomains. In contrast, Multidomain SSL certificates allow combining various internet addresses such as example.org, name.de, and beispiel.xyz without restrictions. Depending on usage, this offers users various advantages:

• Lower costs compared to numerous individual single-name certificates
• Easy management through a central certificate instead of multiple separate ones
• Uniform validity and duration for all domains
• Easy setup of multiple addresses for a single website
• For a few subdomains, sometimes cheaper than a Wildcard certificate
• Free combination with up to several hundred domains
• Unlimited distribution across any number of servers
• Uniform encryption of data transmission via SSL/TLS
• Possible combination as Wildcard Multidomain SSL certificates

Multidomain SSL certificates are particularly interesting for companies, online shops, and other commercial projects looking to expand their reach through multiple domains. They allow for easy setup with minimal effort and enable the use of a single web hosting or a dedicated server or Virtual Private Server for all web presences without the need for complex configurations.

Furthermore, Multidomain SSL certificates prove useful for companies that, for various reasons - such as multilingualism, regionalization, or complex product ranges - rely on multiple websites. They allow for centralized organization with a uniform IT environment, simplifying management significantly and enabling efficient, secure, and shared administration.
