GeoTrust QuickSSL Premium Wildcard is an advanced SSL/TLS certificate that provides comprehensive security for both the main domain and all first-level subdomains, enabling secure connections with a single certificate. The certificate supports both RSA algorithms and the modern ECC (Elliptic Curve Cryptography), which provides flexibility in choosing the encryption technology. RSA supports key lengths of up to 4096-bits, providing strong security, while ECC, due to its efficiency, offers a comparable level of security with much shorter keys (e.g. a 256-bit ECC key corresponds to a 3072-bit RSA key), which leads to higher performance and lower server load. The certificate offers 256-bit data encryption using modern cryptographic protocols such as SHA-2, which ensures optimal protection of transmitted data. Thanks to its wide compatibility with web browsers (over 99%) and mobile devices, the certificate guarantees reliable security on a wide range of platforms.

The validation process is based on the Domain Validation (DV) method, which only requires confirmation of domain control, via email or adding a special DNS record. This simplified approach allows for the certificate to be issued quickly, usually within minutes of submitting the application, making it ideal for companies that need immediate security implementation. GeoTrust QuickSSL Premium Wildcard also offers a dynamic GeoTrust trust seal that can be placed on a website to increase the credibility of the site in the eyes of visitors. This seal informs users about the SSL security used, which is especially important for e-commerce sites or other applications processing sensitive data. Additionally, the certificate is backed by a $500 000 guarantee, providing an additional layer of protection in case of any security issues.

The GeoTrust QuickSSL Premium Wildcard security seal, also known as the GeoTrust Secured Seal, is a dynamic trust mark that can be placed on a website to visually confirm the site’s security. This seal shows that the site uses a GeoTrust QuickSSL Premium Wildcard SSL/TLS certificate, which means that data transmission between users and the server is secured with advanced encryption. With the GeoTrust security seal, site visitors can be assured that their data, such as personal or financial information, is protected from unauthorized access. Placing this seal on a site increases user trust, which can translate into higher conversion rates, especially for e-commerce sites or sites that require sensitive data. The seal is dynamic, meaning that when a user clicks on it, they can see additional information about the SSL certificate, including details about its issuer and validity. This is an additional level of transparency that strengthens the credibility of the site. The GeoTrust Secured Seal is also compatible with most browsers and mobile devices, ensuring that the seal is displayed consistently across platforms, regardless of the device used. Displaying the GeoTrust Secured Seal on your site not only indicates the use of an SSL certificate, but also underscores the company’s commitment to ensuring the security of its users.

The validation procedure for GeoTrust QuickSSL Premium Wildcard is based on the domain validation method, however, given the specifics of Wildcard certificates, the file placement method on the server cannot be used. The process begins with a certificate application, after which control over the domain must be confirmed using one of two methods. The first option is email validation, in which an email with a link to validation is sent to the address associated with the domain, such as admin@domain.com. The second option is DNS record validation, where a special TXT record is added to the domain’s DNS zone, confirming ownership. After one of these methods is carried out and verification is successfully completed, the certificate is issued and its installation can be performed on the server to secure the main domain and all subdomains.

Important: Wildcard SSL certificates cannot be verified via file.

The Wildcard feature in the GeoTrust QuickSSL Premium Wildcard certificate allows you to secure not only your main domain, but also all of its subdomains with a single SSL/TLS certificate. This means that once the certificate is installed on your server, both your main domain (e.g. example.com) and all of your subdomains (e.g. mail.example.com, shop.example.com) will be protected by the same SSL encryption. The Wildcard feature is especially useful for companies and organizations that have multiple subdomains and want to simplify certificate management by eliminating the need to issue separate certificates for each. This saves you time and resources while providing consistent security for your entire domain environment. A Wildcard certificate works at the first-level subdomain level, meaning it secures all subdomains at one level, but does not extend to subdomains at subsequent levels (e.g. sub1.sub2.example.com).

GeoTrust certificates, including GeoTrust QuickSSL Premium Wildcard, are compatible with a wide range of web browsers and mobile devices. This compatibility includes about 99% of the most popular browsers, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and browsers based on WebKit and Gecko. When it comes to mobile devices, GeoTrust certificates work without a problem on most operating systems, such as Android, iOS, Windows Phone, and browsers native to these platforms. This means that users using various devices, from smartphones to tablets, can safely browse websites protected by GeoTrust certificates without worrying about compatibility issues. These certificates are also supported by mail servers, email clients, and mobile applications, providing comprehensive security at various levels of digital communication.
