The validation procedure for the Sectigo Multi-Domain EV SSL certificate is a multi-step process that provides the highest level of security and credibility for the organization. The process begins with verification of the legal existence of the company, where Sectigo checks the company’s registration in the appropriate state registers and confirms the legal status of the organization. Then, the physical address of the company’s headquarters is verified, which may include an analysis of address documents or other forms of location confirmation. The next step is to confirm the operational activity of the organization, which is intended to ensure that the company is active and operates on the market in accordance with the declared information. Sectigo also thoroughly checks the authorizations of the person responsible for applying for the certificate to ensure that this person has the appropriate permissions to represent the organization in the process of obtaining the certificate. An important element of the procedure is also the verification of control over all domains that are to be secured by the certificate. The organization must prove that it has the appropriate rights to manage each of the domains covered by the certificate, which is crucial to ensuring the integrity and security of the company’s online environment. As part of this verification, Sectigo uses a variety of methods to confirm domain control, including email, HTTP/HTTPS, and DNS verification. Email verification involves sending a message to the registered administrative email address of the domain, which must be confirmed by an authorized person. The HTTP/HTTPS method requires a specially prepared file to be placed on the domain server, which confirms that the applicant has direct access to the server. Alternatively, DNS verification involves adding a specific TXT record to the domain’s DNS configuration, which proves control over its settings. The entire process is carried out in accordance with international industry standards and best practices in cybersecurity, ensuring that the Sectigo Multi-Domain EV SSL certificate meets the highest requirements for data protection and organizational authenticity. Thanks to this rigorous validation procedure, companies can be sure that their EV SSL certificate is not only technically advanced, but also helps build trust with customers and business partners.

The multi-domain feature in the Sectigo Multi-Domain EV SSL certificate is a key aspect of this advanced security solution, enabling enterprises to effectively manage and protect multiple Internet domains with a single certificate. With this feature, organizations can secure multiple root domains and their subdomains, which significantly simplifies the administrative process and reduces the costs associated with managing separate certificates for each. The multi-domain feature in the Sectigo EV SSL certificate is implemented via Subject Alternative Names (SAN), which allow multiple domain names to be added to a single certificate. This allows the certificate to secure up to 250 different domains, which is especially beneficial for large enterprises operating in multiple markets or with extensive online infrastructure. This flexibility allows for centralized security management, which in turn makes it easier to monitor and update certificates, minimizing the risk of configuration errors and potential security holes. Additionally, the multi-domain feature in the Sectigo EV SSL certificate supports dynamic domain management, allowing domain names to be easily added or removed without having to renegotiate the entire certificate.
