Buy Multi Domain Wildcard SSL to protect multiple domains and their subdomains

It is the most flexible tool in the Sectigo lineup. It combines two technologies: Multi-Domain (SAN) and Wildcard. This allows you to secure completely different domains (for example, site.com, my-app.net, service.org) and all their first-level subdomains in one certificate.

The basic package usually includes 3 domains (FQDN), but technically the certificate supports expansion up to 250 different domain names. You can activate the subdomain protection option for each of them.

For each domain in the SAN (Subject Alternative Name) list, you specify a wildcard mask, for example, *.site.com. This automatically activates encryption for shop.site.com, api.site.com, and any other subdomains of that name.

It is indispensable for owners of large networks of sites (PBN), web studios supporting client projects, and companies with a sprawling infrastructure (different brands or regional sites on different domains).

Yes, and this is its main advantage. Instead of tracking expiration dates for 10 or 20 different SSLs, you manage one certificate file and one renewal date for your entire network of resources.

This certificate refers to the DV (Domain Validation) type. This means the verification is as simple as possible: via email, DNS records, or HTTP files for each listed domain. No paper documents are required.

Yes, you can add additional domains or subdomains at any time during the certificate's validity through the reissuance process.

Sectigo Multi-Domain Wildcard is fully compatible with Cloudflare, Amazon Web Services (AWS), Microsoft Azure, and most popular CDN networks, making it an excellent choice for cloud applications.

Yes, you can use it to secure IMAP, POP3, and SMTP connections. With SAN support, you can include mail.domain.com, smtp.other-domain.net, and secure them.

This professional solution comes with an insurance warranty of $250,000. This reinforces the high level of trust the certification authority has in the security of its encryption nodes.

Visitors will see the familiar 'gray lock' and HTTPS protocol. When viewing certificate information, all domains you are securing will be listed in the 'Subject Alternative Name' field.

No, this certificate is designed exclusively for domain names and their subdomains. The protection of public IP addresses is not provided for this model.

Thanks to SNI (Server Name Indication) technology, modern servers allow a multi-domain certificate to be installed on a single IP address for all your sites, which saves hosting resources.

It is completely safe. AES-256 encryption standard is used, and each domain undergoes an independent ownership verification before being included in the overall chain.

Buying one Multi-Domain Wildcard usually costs 40-60% less than buying 3-4 separate Wildcard certificates. Plus, you save working time on installation and updates.
