Sectigo Multi-Domain SSL (OV) certificate is an advanced security solution that allows you to simultaneously secure multiple domains, subdomains and network resources using a single SSL/TLS certificate. Its main feature is organizational validation (OV), which means that in addition to ensuring communication encryption, the certificate also confirms the authenticity of the organization that owns the domains. The OV validation process includes detailed verification of the company’s identity by checking registration documents and independent confirmation of organizational data, which increases user confidence in the website. The Sectigo Multi-Domain SSL (OV) certificate supports securing up to 250 different domains and subdomains, making it an ideal solution for companies managing complex network infrastructure. The certificate supports the latest encryption technologies, including cryptography based on 2048-bit RSA keys and Elliptic Curve Cryptography (ECC), which ensures both a high level of security and performance. Choosing ECC allows for increased cryptographic efficiency while maintaining strong protection, which is especially important in high-load environments.

The certificate is compatible with most popular web browsers and mobile devices, ensuring that users can safely connect to your site without compatibility issues. In addition, Sectigo Multi-Domain SSL (OV) supports Unified Communications Certificate (UCC), which allows you to secure not only standard domains, but also specific server resources such as Microsoft Exchange servers or Office Communications Server. The UCC feature allows for flexible management of multiple hostnames and domains within a single certificate, which is especially useful in corporate and cloud environments. The certificate includes a static security seal that can be placed on websites to confirm the status of the certificate and verify the identity of the organization. This is a visible sign to users that the site is secure and that the organization has been successfully verified. This seal is not interactive or updated in real time, but provides a visible confirmation of security, increasing the trust of visitors.

The Sectigo Multi-Domain SSL (OV) certificate is an advanced and flexible solution that not only simplifies certificate management in complex network environments, but also ensures full data protection and compliance with the highest security standards. With support for both traditional RSA encryption methods and modern ECC algorithms, it is a certificate that meets the needs of the most demanding organizations, guaranteeing security, reliability and ease of managing SSL/TLS certificates in a multi-domain environment.

• Multiple Domain and Subdomain Security: The Sectigo Multi-Domain SSL (OV) certificate allows you to simultaneously secure up to 250 different domains and subdomains within a single certificate, simplifying certificate management in complex network infrastructures.
• Organization Validation (OV): The certificate provides full Organizational Validation (OV), meaning that the organization’s identity is thoroughly verified before the certificate is issued. Company data is visible in the certificate, which builds user confidence in the secured website.
• Strong encryption based on RSA and ECC: The certificate supports both traditional RSA encryption with a 2048-bit key length and modern, more efficient encryption based on Elliptic Curve Cryptography (ECC), which provides a high level of security while increasing performance and optimizing resources.
• SHA-2 protocol compliance: The certificate uses SHA-2 hash algorithms, which are currently considered the most secure cryptographic standards, providing an additional layer of protection against potential threats.
• Dynamic domain name management: Users can flexibly add, remove, or modify domains and subdomains within the certificate, allowing for dynamic adaptation to changes in the IT infrastructure without having to regenerate a new certificate.
• UCC Compatibility: The certificate supports the Unified Communications Certificate (UCC), which enables you to secure specific server resources such as Microsoft Exchange and Office Communications Servers, while providing protection for multiple domain names and hostnames.
• Browser and Mobile Device Compatibility: The certificate is compatible with most modern web browsers and mobile devices, providing broad coverage and minimizing compatibility issues, ensuring that user data is always protected.
• Static Security Seal: Sectigo Multi-Domain SSL (OV) offers a static security seal that can be displayed on web pages, providing a visible sign to users that the page is secure and protected by an SSL certificate.
• Phishing Protection: Organization-level Validation (OV) makes it much more difficult for potential attackers to impersonate your company, increasing user security and reducing the risk of attacks phishing.
• Cost and resource optimization: By securing multiple domains with a single certificate, organizations can significantly reduce the costs associated with purchasing and managing multiple certificates, simplifying administration and providing easier management.

Sectigo Multi-Domain SSL (OV) certificate security seal is a visible element that organizations can place on their websites to increase user confidence. This certificate features a static security seal that provides visual confirmation that the site is protected by an SSL/TLS certificate issued by a trusted provider such as Sectigo. The static security seal is not interactive, meaning it does not offer the ability to click or obtain additional information about the status of the certificate in real time. However, the presence of such a seal on a page gives users a clear signal that the site uses SSL/TLS encryption-based security and has passed Organizational Validation (OV). It is a clear sign to visitors that the data transferred between the browser and the server is safe, which increases the sense of trust and comfort when using the site. The Sectigo seal is widely recognized and associated with a high level of security, which helps companies emphasize their commitment to protecting user data and compliance with international standards for Internet security.

The validation procedure for the Sectigo Multi-Domain SSL (OV) certificate includes several key steps to confirm the identity of the organization that is applying for the certificate. After submitting the certificate application, Sectigo conducts verification of the information provided by the applicant. This process begins with checking the domain registrations to ensure that the applicant has the right to use them. Then, the organization must provide documents confirming its existence and the right to conduct business. Sectigo checks these documents against independent databases, such as company registries, to confirm the authenticity of the entity. Additionally, the validation process may include a phone or email contact with a company representative to verify the details provided in the application. Only after successfully passing all the verification stages, the certificate is issued. The entire procedure is aimed at ensuring that the SSL/TLS certificate is granted only to verified organizations, which increases the level of trust of users visiting secured websites.

The multi-domain feature in the Sectigo Multi-Domain SSL (OV) certificate combines with Unified Communications Certificate (UCC) technology, which enables securing not only multiple domains and subdomains, but also different host names, especially in environments where support for applications such as Microsoft Exchange or Office Communications Server is crucial. The UCC certificate allows securing multiple names simultaneously, both root domains and subdomains, as well as specific server resources such as mail servers or communication servers. Thanks to the UCC feature, the Sectigo Multi-Domain SSL (OV) certificate enables securing many different types of domain names within a single certificate, which significantly simplifies certificate management in complex environments. For example, you can secure both Internet domains (e.g. example.com, example.net), subdomains (e.g. mail.example.com), as well as different resource names within the same servers (e.g. autodiscover.example.com, owa.example.com). This flexibility is especially useful in corporate IT environments where different communication services and domains are supported. A multi-domain certificate with UCC functionality also reduces the number of certificates that need to be monitored and renewed, which in turn translates into lower administrative costs and greater operational efficiency. Domain and hostname management within a UCC certificate is flexible, allowing domains and resource names to be added or removed during the certificate life cycle without the need to register new certificates for each change. The UCC functionality in the Sectigo Multi-Domain SSL (OV) certificate provides a versatile and scalable solution for organizations that need to secure multiple resources within a single, integrated certificate.
