Sectigo PositiveSSL Multi-Domain certificate is an advanced multi-domain solution that provides solid security for multiple domains at once, allowing users to secure different websites without having to manage multiple certificates. This certificate supports both RSA and ECC encryption algorithms, giving users the flexibility to choose between the traditional, widely used RSA encryption with a key length of up to 4096-bits, and the modern and more efficient ECC (Elliptic Curve Cryptography) algorithm, which offers a higher level of security with smaller key sizes. The Sectigo PositiveSSL Multi-Domain certificate is especially suitable for companies and organizations managing multiple domains, offering the possibility of securing up to 250 domains within a single certificate. Thanks to domain-level validation (DV), the certificate issuance process is fast and does not require complex formalities, which significantly speeds up the implementation of security.

The Sectigo PositiveSSL Multi-Domain Certificate Security Seal is a static graphic that website owners can place on their website to inform users of the SSL certificate. This seal signals that the connection to the website is encrypted and protected by Sectigo, reinforcing users’ confidence in the security of data transmissions such as logins, passwords, and financial information. Because the seal is static, it does not provide additional information when clicked, nor does it provide real-time status of the certificate. It is a simple image attached to the page that confirms the presence of an SSL certificate. It can be easily placed anywhere on the page, typically in the footer or on transaction pages, to provide users with visual confirmation that their data is protected.

The validation procedure for the Sectigo PositiveSSL Multi-Domain certificate is based on domain validation (DV), which means that the identity verification process only concerns whether the certificate applicant has control over the given domain. After submitting the certificate application, Sectigo sends an email to the address associated with the domain, e.g. admin@domain.com, webmaster@domain.com, to verify that the applicant has control over the domain. The recipient must click on the link contained in the email, which confirms that they have rights to the domain. Alternatively, validation can be done using DNS records or a file placed on the domain server, which allows for confirmation of authorization without the need to interact with email. After successful validation, the certificate is issued and sent to the user, who can install it on the server to secure connections.

Multi-Domain feature in the Sectigo PositiveSSL Multi-Domain certificate allows you to secure multiple domains with a single SSL certificate. This means that website owners can protect up to 250 different domains, subdomains or websites using a single certificate, which significantly simplifies security management and reduces costs. This feature is especially useful for companies and organizations that have multiple websites, online stores or web applications running under different domains. The certificate allows you to add domains to an existing certificate at any time during its validity, which gives you flexibility in the event of business expansion or the introduction of new sites. All domains are secured using the same SSL/TLS encryption, providing the same level of protection for all connected websites. This means that instead of issuing a separate certificate for each domain, you can manage a single certificate, which makes it much easier to install, renew and monitor.

Sectigo PositiveSSL Multi-Domain certificate is widely compatible with most web browsers and mobile devices, making it an effective solution for website owners who want to ensure secure connections regardless of the platform used by visitors.
