In line with our continuous development of our offerings and our commitment to ensuring the highest security standards in the IT environment, we are pleased to announce the introduction of Certum Multi-Domain certificates in three validation variants: DV (Domain Validation), OV (Organization Validation), and EV (Extended Validation).
Multi-Domain certificates (SAN – Subject Alternative Name) allow the protection of up to 300 domains and subdomains with a single certificate, optimizing costs and simplifying administration. Depending on the selected validation level (DV, OV, EV), they offer varying degrees of trust tailored to industry and regulatory requirements.

| Certum Premium EV Multi-Domain | EV | up to 7 days | Dynamic | Single Domain / Multiple Domains / Multiple Subdomains | 1 000 000 € | $126.00 | Details |
Multi-level Validation: DV, OV, EV
Each variant of the certificates has been designed with different needs and risk levels in mind:
- DV (Domain Validation)
Domain validation enables the quick and automatic issuance of the certificate. The process is based on verifying domain ownership, making it an ideal solution for sites that require basic data transmission security.
- OV (Organization Validation)
For OV certificates, in addition to domain verification, a detailed verification of the organization is carried out. This process includes confirming the legal and physical company details, which results in a higher level of trust among users and customers utilizing online services.
- EV (Extended Validation)
EV certificates represent the highest level of validation, where, besides the standard verification of the domain and organization, a rigorous analysis of the entity’s legal and operational documentation is conducted. The outcome of this process is a browser address bar displaying a highlighted organization name, significantly enhancing the site’s credibility.
Applications and Benefits of Multi-Domain Certificates
Thanks to the support for multiple domains under a single certificate, the Multi-Domain solution is ideally suited for environments where managing multiple websites or subdomains is key. The main benefits are:
- Centralized management – simplified administration of certificates for various domains from a single management panel.
- Cost reduction – eliminating the need to purchase separate certificates for each domain.
- Deployment flexibility – the ability to dynamically add or remove domains without having to rebuild the entire security infrastructure.
- High security standards and regulatory compliance
Our certificates fully comply with international security standards such as X.509 and the requirements of web browsers. This not only ensures secure communication but also full interoperability within the global digital ecosystem. The introduction of Certum Multi-Domain certificates in the DV, OV, and EV variants responds to the growing market demands for securing internet communications. Our PKI solutions, based on the latest cryptographic technologies, guarantee the highest level of data protection while offering flexibility and ease of management.
