A wildcard certificate is designed to secure a primary domain and an unlimited number of its first-level subdomains. When applying for a wildcard certificate denoted by an asterisk and the primary domain name (e.g., .example.com), the organization can cover checkout.example.com, support.example.com, and any other subdomains at the same level. This would be a more streamlined and flexible approach than a multi-domain certificate that only covers the two subdomains currently used. Individually issued certificates can increase complexity and cost. A self-signed certificate typically triggers security warnings in web browsers for not being issued by a trusted third-party, resulting in reduced trust from site visitors. Meanwhile, certificates from an internal issuing authority can be ideal for internal communication but might not be trusted automatically by external clients’ web browsers.
