GeoTrust QuickSSL Premium SAN is a Domain Validation (DV) SSL certificate designed to quickly and effectively secure multiple domains or subdomains using a single SSL certificate. It initially provides protection for one main domain and four additional subdomains, with the option to expand protection to a maximum of 250 SAN (Subject Alternative Name) domains. This makes it ideal for companies with extensive network infrastructures looking for cost-effective and easy-to-manage security.

The certificate provides 256-bit data encryption, which complies with the latest security standards for information transmission. GeoTrust QuickSSL Premium SAN supports both 2048-bit RSA keys and modern ECC (Elliptic Curve Cryptography) keys, allowing you to choose more efficient cryptographic algorithms while maintaining the highest level of protection. The validation process is fully automated and is based on verifying domain ownership rights, which allows you to obtain a certificate in just a few minutes. The certificate is widely accepted by virtually all modern web browsers and mobile devices, ensuring that connections are recognized as secure by the vast majority of users.

GeoTrust QuickSSL Premium SAN is backed by a $500 000 financial guarantee, providing additional security in the event of any issues resulting from certificate errors. Additionally, the ability to place the GeoTrust security seal on your website allows you to increase the trust of visitors, which can have a positive impact on the perception of the site’s security. The technical support available for this certificate covers all stages, from generating the CSR, through installing the certificate on the server, to its configuration in various IT environments, making GeoTrust QuickSSL Premium SAN a comprehensive and professional SSL solution for modern organizations.

GeoTrust QuickSSL Premium SAN offers a dynamic security seal that can be placed on a website to increase user trust. The dynamic seal displays the current security status of the website and, when clicked by a user, shows detailed information about the SSL certificate, such as the company name, certificate expiration date, and issuer information. This is a visible trust mark that not only confirms that the website is protected by an SSL certificate, but also allows visitors to verify in real time the authenticity and validity of the security. As a result, the GeoTrust dynamic seal strengthens the sense of security of visitors and builds the credibility of the website, which has a significant impact on user trust, especially in the context of online transactions.

The multi-domain (SAN) feature in the GeoTrust QuickSSL Premium SAN certificate enables you to secure multiple domains and subdomains with a single SSL certificate. Initially, the certificate protects one main domain and four subdomains, and can be expanded to secure up to 250 additional domains using SAN (Subject Alternative Name) technology. This solution is especially useful for organizations managing complex infrastructures where multiple domains and subdomains require consistent security. The multi-domain feature eliminates the need for separate certificates for each domain, simplifying SSL management and reducing costs. With a single SAN certificate, companies can consolidate protection across multiple domains under one centralized security policy, making them easier to manage and maintain.

The validation procedure for GeoTrust QuickSSL Premium SAN is based on automatic domain verification, which classifies the certificate as a DV (Domain Validation) type. The process begins with placing an order for a certificate and generating a CSR (Certificate Signing Request) on the server to be secured. Then, to verify that the applicant has control over the domain, the GeoTrust system sends an e-mail to the registered domain owner or uses alternative verification methods, such as publishing a DNS record or verifying through a file placed on the server. Once the rights to the domain are confirmed, the certificate is generated and issued within minutes. This process is quick and simple, without the need to provide additional documentation, which allows you to immediately secure your website.

GeoTrust certificates, including QuickSSL Premium SAN, feature broad compatibility with web browsers and mobile devices. They are recognized by almost all modern browsers, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera, ensuring that connections secured with these certificates are automatically recognized as trusted. Additionally, these certificates work on most popular mobile devices, including Android and iOS platforms, ensuring security and trust of users regardless of the device used. As a result, GeoTrust certificates offer versatility and assurance that any website or application will be safe and accessible to a wide audience.
