Single Domain Certificate
A Single Domain Certificate is a type of SSL/TLS certificate that secures exactly one fully qualified domain name (FQDN), such as www.example.com or example.com, but not both unless specified. It provides encryption for data transmitted between a user's browser and the web server, ensuring confidentiality and integrity. These certificates are issued by Certificate Authorities (CAs) and are commonly used for basic website security where only one domain needs protection.
Developers should use Single Domain Certificates when securing a single website or application with a specific domain, as they are cost-effective and straightforward to implement for simple use cases. They are ideal for personal blogs, small business sites, or internal tools that don't require coverage for multiple domains or subdomains. However, for more complex setups with multiple domains, alternatives like Wildcard or Multi-Domain Certificates are recommended.
