DigiCert Secure Site Pro Wildcard certificate security seal is a visual confirmation that a website uses an advanced SSL/TLS certificate that provides the highest level of protection for user data. This seal is a dynamic element that can be placed on websites secured with this certificate, allowing visitors to easily recognize that the site is protected by a trusted provider such as DigiCert. DigiCert Secure Site Pro Wildcard security seal not only reinforces user confidence, but also signals that the site meets the highest security standards, including 256-bit encryption and protection against threats such as phishing and man-in-the-middle attacks. Clicking on the security seal redirects users to detailed information about the certificate, including its issuer, validity period, and secured subdomains. With the security seal, website owners can not only secure their services, but also actively inform their customers about the security measures used, which is especially important for transactional websites, e-commerce and any websites where sensitive personal data is processed. The security seal is therefore not only a technical element, but also a tool for building trust and reputation online.

The validation procedure for the DigiCert Secure Site Pro Wildcard certificate includes several key steps that are intended to confirm the identity of the organization and its right to the domain. The process begins with submitting a certificate application, which requires providing information about the organization and the domain that the certificate is to protect. Then, the identity of the organization is verified, which usually involves providing registration documents, such as an extract from the commercial register or another official document confirming the existence of the company. Confirmation of the physical address and phone number may also be required. The next step is validation of the right to the domain, which is carried out using one of two available methods: email or DNS verification. In the case of email verification, a message with a unique code is sent to the email address associated with the domain (such as admin@domain.com, webmaster@domain.com). Alternatively, DNS verification involves adding a special TXT record to the domain’s DNS configuration. DigiCert checks whether the organization has the appropriate permissions to manage the domain, which is a key element in ensuring security. After successful verification, DigiCert proceeds to issue a certificate, which is then delivered in digital form to the domain owner. The certificate can be installed on the server, which allows for the protection of communication using the SSL/TLS protocol for all subdomains covered by the certificate. The validation process is completed by the activation of the certificate, which provides full encryption and protection of data transmitted via secured websites.

Important: Wildcard SSL certificates cannot be verified via a file.

The Wildcard feature in the DigiCert Secure Site Pro Wildcard certificate allows you to secure an unlimited number of subdomains on a single SSL/TLS certificate. With this feature, instead of issuing separate certificates for each subdomain, an organization can protect all subdomains of a given root domain (e.g. *.example.com) with a single certificate. This significantly simplifies certificate management, reduces costs, and reduces the risk of misconfigurations that can occur when using multiple certificates. A Wildcard certificate covers all subdomains at the level of a single DNS record, meaning that subdomains such as www.example.com, mail.example.com, and shop.example.com will automatically be protected by SSL/TLS without any additional action on the part of the administrator. This feature is especially useful for organizations that frequently create new subdomains or manage a large number of subdomains for different purposes, such as branch offices, different sections of a website, or online services. In the case of the DigiCert Secure Site Pro Wildcard certificate, the Wildcard feature is combined with advanced security technologies, providing the highest level of protection for each subdomain. This certificate offers 256-bit encryption, phishing protection, and advanced technical support, making it one of the most comprehensive solutions on the market for organizations that need flexibility and security in managing subdomains.
