The validation procedure for Certum Premium EV SSL is a comprehensive and rigorous process that aims to ensure the highest level of security and authenticity of the certified entity. This process begins with a thorough legal analysis of the identity of the organization applying for the certificate. Certum, as a reputable provider of certification services, requires the provision of full documentation confirming the legal status of the company, e.g. registration documents or the organization’s articles of association. Then, the physical and operational existence of the entity is verified, which includes confirmation of the existence of a business activity by analyzing address data, telephone contacts and other available public information. The next stage is the verification of the rights to use the Internet domain for which the certificate is to be issued. Certum checks whether the applicant has full rights to manage a given domain, which is done through one of several authorization methods. The first method is to confirm the placement of a special file in a specific HTTP or HTTPS location on the domain server, which proves control over the server. Alternatively, verification can be carried out by adding the appropriate DNS record to the domain configuration, which confirms control over the DNS infrastructure of the given domain. The third method is confirmation via e-mail, where Certum sends a message to the e-mail address associated with the domain (for example admin@domain.pl), and the applicant must respond in accordance with the instructions contained in the message, which confirms their authorization to manage the domain. An important element of the procedure is also the verification of persons authorized to represent the organization in the certificate application process. Certum confirms the identity and authorization of key persons through direct telephone contact and analysis of documents confirming their position and authorizations in the organizational structure. The entire validation process is carried out in accordance with international security standards and industry guidelines, such as ETI (Extended Validation Initiative) requirements. Certum uses advanced tools and technologies to automate some of the procedures, but key stages, such as document verification or contact with the applicant, are carried out manually by experienced specialists. After completing all validation stages and positively verifying all information, Certum issues Certum Premium EV SSL, which provides the highest level of security and confirms the authenticity of the organization on the digital market. Thanks to this meticulous validation procedure, Certum Premium EV SSL not only guarantees advanced technical security through the use of modern cryptographic algorithms such as RSA and ECC, but also builds user trust through the transparency and credibility of the certified organization.
