DigiCert Secure Site Wildcard SSL Certificate is an advanced certificate that provides encryption of communication and authenticity for multiple subdomains under a single root domain. This certificate allows companies and organizations to secure an unlimited number of subdomains on a single certificate, which is especially beneficial for complex network infrastructures with multiple online services. DigiCert Secure Site Wildcard offers the ability to choose between the two most important cryptographic algorithms: RSA and ECC (Elliptic Curve Cryptography). With support for a 2048-bit RSA key and a 256-bit ECC key, this certificate allows you to optimize security and performance according to the requirements of your organization. RSA is a widely accepted standard, offering reliability and compatibility with a wide range of devices and browsers. On the other hand, ECC, due to its lower computing power requirements while maintaining a high level of security, is an ideal choice for resource-constrained environments such as mobile devices. The DigiCert Secure Site Wildcard SSL Certificate provides 256-bit encryption, ensuring the highest level of security for transmitted data. It complies with industry requirements, including PCI DSS and GDPR standards, making it an ideal solution for companies processing sensitive customer data. Support for HTTP/2 protocols and full compliance with the latest cryptographic standards provide additional layers of protection.

This certificate is backed by the renowned DigiCert brand, ensuring reliability and wide compatibility with browsers and devices. It also offers a dynamic security seal, access to 24/7 technical support and certificate management tools, making it easy to maintain and monitor security. DigiCert Secure Site Wildcard also offers a financial guarantee of $1 750 000, protecting against potential losses resulting from security breaches, which further strengthens the trust in the company using this solution.

DigiCert Secure Site Wildcard is the ideal solution for organizations that value both security and flexibility in managing online resources, enabling comprehensive security of all subdomains while supporting the latest cryptographic technologies.

DigiCert Secure Site Wildcard certificate security seal is a dynamic, interactive element that can be placed on a website to visually confirm that the site is protected by an SSL certificate. This seal not only informs visitors about the security of the site, but also reinforces user confidence by showing that the site is secured by a trusted certificate provider like DigiCert. The security seal is dynamic, meaning that when the user hovers over or clicks on the seal, they can see additional information about the certificate, such as its status, expiration date, and details about the organization that owns the certificate. This allows users to quickly verify that the connection is secure and that their data is protected from potential threats. Installing the security seal is a simple process that involves adding the appropriate HTML code to the website. The seal can be placed anywhere on the page, but is most often found in the footer, header, or near forms where users submit their personal information or complete transactions. The DigiCert seal is widely recognized and accepted, further emphasizing the professionalism and security of the organization using this certificate. The presence of a security seal on a website can significantly increase user confidence, which translates into better business results, especially in the case of e-commerce sites, trading platforms and other services requiring a high level of security.

The validation procedure for the DigiCert Secure Site Wildcard certificate begins with an application, in which the organization must provide basic information such as company name, contact details, and domain details. Upon receipt of the application, DigiCert verifies the organization’s identity by checking its data in official trade registers or business databases, which is to confirm that the organization is legally registered and operating under the given name. In parallel, the right to the domain is verified. This part of the procedure can be performed in two ways: by adding a TXT record to the domain’s DNS configuration or by verifying the email address associated with the domain. In the first case, the domain owner must add a unique record to the domain’s DNS zone, which allows DigiCert to confirm that the organization has control over this domain. In the second case, verification is done by sending an email to the address associated with the domain, e.g. admin@domain.com, and the response to this email confirms the right to the domain. After both verification steps have been successfully completed, the DigiCert Secure Site Wildcard certificate is generated and delivered to the organization. This certificate can then be installed on the server, allowing all subdomains associated with the root domain to be secured. The entire validation process is closely monitored by DigiCert to ensure compliance with the highest standards of security and data integrity.

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

Wildcard feature in the DigiCert Secure Site Wildcard certificate allows you to secure an unlimited number of subdomains under a single root domain using a single SSL certificate. Instead of having to purchase separate certificates for each subdomain, a Wildcard certificate allows you to secure all subdomains that match a specific pattern. The key feature of the Wildcard feature is the ability to use an asterisk (*) symbol in the domain name when generating the certificate. For example, if a Wildcard certificate is issued for the domain *.example.com, it secures not only the root domain (example.com), but also all subdomains such as www.example.com, shop.example.com, blog.example.com, and any other subdomains that are added in the future. The Wildcard feature is especially useful for companies and organizations with complex network structures that manage multiple subdomains under a single root domain. It simplifies certificate management and reduces costs by eliminating the need to purchase and maintain multiple certificates for each subdomain. In addition, the DigiCert Secure Site Wildcard certificate offers a high level of security with 256-bit encryption and support for protocols such as HTTP/2, which protects data transferred between the server and the client. The Wildcard feature also provides flexibility and scalability, as newly added subdomains are automatically protected by the certificate, without the need to modify or reissue it. This allows companies to quickly respond to changing business needs by adding new subdomains without worrying about the security of their online communications.
