Sectigo PositiveSSL Multi-Domain Wildcard is an advanced SSL/TLS certificate that allows you to simultaneously secure multiple domains and their subdomains with a single certificate. Thanks to the Wildcard technology, it is possible to protect any number of subdomains within multiple root domains, which significantly simplifies certificate management and reduces operational costs. The certificate offers the flexibility of choosing between two main cryptographic algorithms: RSA and ECC (Elliptic Curve Cryptography). RSA with a 2048-bit key provides solid 256-bit encryption, which is standard in many traditional systems, while ECC offers a higher level of security with less resource consumption, making it ideal for modern applications requiring efficient processing.

PositiveSSL Multi-Domain Wildcard supports up to 250 different domains, and its structure allows for easy addition and removal of domains during the certificate validity period. The Domain Validation (DV) process ensures fast certificate issuance after domain ownership is confirmed, which is ideal for environments requiring fast security implementation. The certificate is fully compliant with the latest SSL/TLS protocols, including SHA-2, which ensures resistance to modern cryptographic attacks. With wide browser compatibility (over 99.9%) and mobile devices, it guarantees trouble-free operation on various platforms.

Additionally, Sectigo PositiveSSL Multi-Domain Wildcard offers unlimited re-issues and unlimited installations on different servers, making it a highly flexible solution. The set also includes a financial guarantee from Sectigo of $50 000, which provides additional financial protection and confirms the reliability of the product. By choosing this certificate, you get a complete SSL/TLS solution that combines high performance, flexibility and security for complex web environments.

• 256-bit encryption with 2048-bit RSA key and ECC support: The certificate provides advanced encryption using 256-bit data encryption and 2048-bit RSA key, while also offering the option of using elliptical key cryptography (ECC) for higher performance and security.
• Support for multiple domains and subdomains (Multi-Domain Wildcard): The certificate allows you to simultaneously secure up to 250 different domains and all of their subdomains, eliminating the need to manage separate certificates for each domain and subdomain, greatly simplifying SSL administration.
• Compatibility with 99.9% of browsers and mobile devices: The certificate is compatible with the most popular browsers, such as Chrome, Firefox, Safari, Opera, and Edge, as well as a wide range of mobile devices, including iOS and Android systems, ensuring a secure connection across platforms.
• Domain Validation (DV): The validation process is fast and automatic, meaning that a certificate can be issued within minutes of confirming domain ownership, without the need to provide additional company documents.
• Unlimited re-issues and installation on different servers: The user has the option of unlimited re-issue of the certificate and installation on multiple servers, allowing for flexible certificate management in complex server environments.
• Support for SHA-2 protocols and the latest SSL/TLS standards: The certificate supports modern cryptographic protocols, including SHA-2, which provides protection against modern security threats and compliance with the latest SSL/TLS standards.
• Static Secure Site Seal from Sectigo: The static security seal can be placed on a website to inform visitors that the site is protected by an SSL certificate. This seal builds user trust, although it is not interactive.
• $50 000 guarantee from Sectigo: The certificate includes a $50 000 financial guarantee, which provides additional protection in the event of a certificate-related security breach, strengthening the credibility of the solution.
• Flexibility in domain and subdomain expansion: Easily add or remove domains and subdomains during the certificate’s validity period, making it easier to manage dynamic web environments.
• PCI-DSS and other industry compliance: The certificate supports compliance with security requirements such as PCI-DSS (Payment Card Industry Data Security Standard), making it a suitable solution for websites handling online transactions.

Sectigo PositiveSSL Multi-Domain Wildcard certificate security seal is a static graphic that can be placed on your website to inform visitors that your website is protected by an SSL certificate. This seal symbolizes that all data transferred between the user’s browser and the server is encrypted, which increases the level of security and builds trust among users. Unlike dynamic seals, the static seal does not provide detailed information when clicked, but it still plays an important role in increasing the credibility of the site. To add it to the website, the certificate owner receives the appropriate HTML code from Sectigo, which can be easily placed on the website, for example in the footer or on the home page. Placing the seal on the website increases the visibility of SSL security, which is especially important for websites conducting online transactions or collecting personal data, because users see that their information is protected by a trusted certificate provider like Sectigo.

The validation procedure for the Sectigo PositiveSSL Multi-Domain Wildcard certificate is based on domain validation (DV), which means that it is only necessary to confirm domain ownership, without the need to provide additional company documents. After placing an order for a certificate, the user receives an email asking for domain validation. This confirmation can be done by clicking on the verification link in the email sent to the address associated with the domain, or by alternative methods such as adding a DNS record or uploading an HTML file to the server. After successful confirmation, the certificate is generated and ready for installation. This process usually takes a few minutes, and because it is a domain-level validation, it is a quick and easy way to obtain an SSL certificate for multiple domains and subdomains.

Important: Wildcard domains cannot be verified via a file.

The Multi-Domain feature in the Sectigo PositiveSSL Multi-Domain Wildcard certificate allows you to simultaneously secure multiple different domains and their subdomains with a single SSL certificate. With this feature, the user can protect not only the main domain, but also any number of subdomains within multiple different domains, which significantly simplifies certificate management and reduces costs. The Multi-Domain feature works in such a way that the certificate can cover up to 250 different domains and their subdomains. In practice, this means that instead of managing several separate certificates for each domain and subdomain, you can use a single certificate, which reduces the time and resources needed for their administration. PositiveSSL Multi-Domain Wildcard supports both RSA and ECC algorithms, which gives you flexibility in choosing the level of security and optimizing performance. This certificate is compatible with most browsers and mobile devices, which ensures smooth operation and wide availability for end users. The Multi-Domain feature in this certificate allows for unlimited domain addition or removal during its validity, as well as re-issue of the certificate at any time. This solution offers optimal security for companies managing complex online environments that require protection of multiple domains and subdomains in a simple and efficient way.

The Wildcard feature in the Sectigo PositiveSSL Multi-Domain Wildcard certificate allows you to secure not only a single domain, but also all of its subdomains with a single SSL certificate. This feature saves time and resources by eliminating the need to manage separate certificates for each subdomain. The Wildcard feature works by using the “*” (asterisk) symbol to represent all possible subdomains under a given root domain. For example, if the certificate covers the domain “example.com”, the Wildcard feature can automatically secure all of the subdomains, such as “blog.example.com”, “shop.example.com”, and “mail.example.com”. In the case of the Multi-Domain Wildcard certificate, this feature extends to multiple domains, allowing you to secure multiple root domains and their subdomains with a single certificate. With this solution, enterprises can simplify SSL certificate administration and provide consistent security on a large scale. The Wildcard feature is ideal for organizations that manage a large number of subdomains, as it provides flexibility and ease in scaling the infrastructure. The certificate also supports unlimited re-generation and installation on different servers, making it a versatile tool for managing online security in dynamic environments.
