The validation procedure for the Sectigo EnterpriseSSL Pro EV Multi-Domain certificate is detailed and rigorous, designed to confirm the highest level of trust in the identity of the organization applying for the certificate. The process includes several key steps that ensure that only legally registered and verified entities receive a certificate with Extended Validation (EV). The first step is to verify the legal existence and identity of the organization. Sectigo checks the company registration documents against official government registries or through authorized independent sources. The aim is to confirm the full legal name, legal form, registered address and current legal status of the entity. Next comes the verification of the physical presence of the organization. This requires confirmation that the company actually operates at the physical address provided. This may involve checking records in databases such as business registers, or requiring the provision of supporting documents such as utility bills or lease agreements. The next step is to verify the domain rights. Sectigo must ensure that the organization has the right to manage the domains that are to be covered by the certificate. This process usually consists of confirming ownership via email sent to the address associated with the domain, DNS records or via a file placed on the web server. Another important element is the verification of the organization’s phone number. Sectigo confirms the phone number through independent sources, such as official databases or phone books. Then, it makes a phone call to the organization to confirm the data and obtain final authorization from an authorized person. The last step is to verify the person authorized to represent the organization. Sectigo must ensure that the person requesting the certificate has the appropriate authorization. This may require providing written confirmation, such as an authorization letter signed by the company’s senior management. The entire validation process is carried out in accordance with the guidelines set by the CAB Forum (Certification Authority Browser Forum) and can take from several days to several weeks, depending on the speed of submission of the required documents and the complexity of the company’s organizational structure. Thanks to this detailed procedure, the Sectigo EnterpriseSSL Pro EV Multi-Domain certificate provides the highest level of trust and security, confirming the authenticity of the organization to its customers and business partners.

Sectigo EnterpriseSSL Pro EV Multi-Domain certificate offers advanced multi-domain functionality that allows you to secure multiple domains and subdomains simultaneously with a single SSL/TLS certificate. This functionality is especially beneficial for enterprises managing extensive network infrastructures, where maintaining separate certificates for each domain can be complicated and expensive. Thanks to Subject Alternative Name (SAN) technology, the certificate allows you to add up to 250 different domain names in a single certificate, including both root domains and subdomains. The multi-domain functionality simplifies certificate management, reducing the administrative burden of monitoring expiration dates, renewing and installing multiple certificates on different servers. Using a single certificate to secure multiple domains brings significant financial and operational benefits. Organizations can reduce the costs associated with purchasing and maintaining certificates, while increasing the efficiency of IT departments. Centralized management of the multi-domain certificate also makes it easier to maintain consistent security policies throughout the organization, which is crucial for compliance with regulations such as GDPR and PCI DSS. The multi-domain feature does not compromise the security level or performance of connections. The certificate still offers the highest level of authentication through Extended Validation (EV), which provides users with visible confirmation of the website’s trustworthiness, such as displaying the company name in the browser address bar. In addition, support for modern cryptographic algorithms, including Elliptic Curve Encryption (ECC), guarantees strong data security during transmission. The flexibility of the multi-domain feature allows domains to be added or removed during the certificate’s validity period, which is especially important in a dynamic business environment. Organizations can quickly respond to changing needs, e.g. introducing new services or products under different domains, without having to go through the full process of issuing a new certificate for each change. The multi-domain feature in the Sectigo EnterpriseSSL Pro EV Multi-Domain certificate is an effective and scalable solution for enterprises that need to secure multiple domains while maintaining the highest standards of security and trust. It simplifies certificate management, optimizes operational costs and increases operational flexibility, which translates into better data protection and building a strong brand reputation in the digital environment.
