GoGetSSL Multi-Domain SSL (FLEX) is an advanced SSL certificate designed to comprehensively secure communication across multiple domains, subdomains, IP addresses, and wildcard domains using a single SSL/TLS certificate. The certificate utilizes SAN (Subject Alternative Name) technology, allowing the integration of up to 250 alternative domain names within one installation, which optimizes the security management of websites, mail servers, and applications across diverse IT environments. It supports both traditional RSA asymmetric encryption with a 2048-bit key and modern Elliptic Curve Cryptography (ECC), which provides an equivalent level of security using shorter keys (e.g., 256-bit), thereby increasing the efficiency of cryptographic operations. It also supports symmetric encryption with the AES algorithm up to 256-bit, in compliance with current TLS 1.2/1.3 standards.

Certificate operates on an innovative FLEX model that enables simultaneous protection of standard domains, subdomains, public IP addresses, and wildcard domains. While separate Multi-domain (SAN) and Multi-Domain Wildcard certificates exist, they do not allow the combination of different SAN types (regular and wildcard). With FLEX, you can mix wildcard domains, IP addresses, and regular domains without needing to change to a different certificate—all within a single solution.

Certificate issuance process is based on Domain Validation (DV), automated by the GoGetSSL system, which reduces activation time to just a few minutes (verification via DNS, email, or an HTML file – note that this does not apply to wildcard domains). The flexibility of the solution is demonstrated by the ability to modify the SAN list after the certificate has been issued, thanks to the free reissue feature available in the administration panel. The certificate integrates with most server environments, including Apache, Nginx, and IIS, as well as cloud platforms (AWS, Azure), ensuring compatibility with over 99.9% of browsers and devices, regardless of the chosen encryption technology (RSA/ECC). Under the offer, users receive a financial guarantee of up to $50 000, protecting against the consequences of potential SSL breach incidents. The certificate also ensures compliance with GDPR and PCI DSS requirements, along with high-quality technical support. GoGetSSL Multi-Domain SSL FLEX eliminates the need to maintain multiple certificates, reducing costs and comprehensively managing their life cycle, making it the ideal choice for organizations that value scalability, high availability, and versatility in data protection.

GoGetSSL Multi-Domain SSL FLEX offers a static Site Seal, which is a graphical symbol confirming the SSL’s activation and validity on the website. The seal appears in the form of a logo (an image in PNG or SVG format) with encryption information that can be manually embedded in the footer or any chosen location on the site. It is compatible with various browsers and devices, and its primary purpose is to visually enhance user trust by indicating a secure connection. Unlike dynamic versions, this seal does not display interactive certificate details (e.g., expiration dates or organization names) nor does it automatically adapt to the user’s language.

The validation procedure for the GoGetSSL Multi-Domain SSL Flex certificate is based on domain validation (DV) by confirming control over them. After placing an order, you must provide a list of domains and subdomains (within the SAN limit) to be secured. GoGetSSL initiates the validation process by sending a verification email to addresses associated with the domains (e.g., admin@domain, administrator@domain, or addresses specified in the WHOIS record). Alternatively, domain ownership can be verified by adding a DNS TXT record or by placing a verification file on the server (this does not apply to wildcard domains). Each domain/subdomain/IP address/wildcard domain requires individual confirmation, and after successful verification, the certificate is generated and made available for download. The process is typically fast (a few minutes to a few hours), provided that the information in the order is correct and that responses to emails or DNS/file modifications are completed in a timely manner.

Important: Wildcard domains cannot be verified via file.

The FLEX feature in the GoGetSSL Multi-Domain SSL Flex certificate is an innovative solution that enables dynamic certificate management in an environment with evolving business needs. Thanks to this feature, users can flexibly add or remove domains, subdomains, wildcard domains, and IP addresses without having to reissue the certificate, significantly speeding up the configuration update process. Automatic validation mechanisms and API integration ensure that changes are implemented quickly, securely, and in accordance with the latest cryptographic standards. The FLEX feature also guarantees full compliance with international security standards while optimizing operational costs and minimizing the risk of errors resulting from manual configuration. This solution is a revolutionary and ideal tool for companies rapidly expanding their online presence, enabling uninterrupted protection and flexible adaptation to changing market requirements.

GoGetSSL Multi-Domain SSL Flex ensures broad compatibility with most modern web browsers (such as Chrome, Firefox, Safari, Edge) and mobile devices (including iOS and Android systems). It operates reliably by utilizing trusted root Certification Authorities, whose lists are updated in operating systems and browsers. The certificate is recognized by the latest software versions and also remains compatible with older devices, provided that the server is correctly configured and current certificate chains are present. GoGetSSL ensures that their solutions meet industry standards, minimizing the risk of trust-related error messages. Check the full list of supported devices and web browsers.

Technical support for the GoGetSSL Multi-Domain SSL FLEX certificate is available year-round. Clients can contact support via live chat on the GoGetSSL website, a support ticket form in the client panel, or email, receiving assistance with issues such as the domain validation process, CSR generation, certificate installation on the server (Apache, Nginx, IIS, etc.), or troubleshooting compatibility errors.
