Why do you need an SSL certificate?
An SSL certificate not only encrypts data transmission between the user and the website but also increases trust among visitors and search engines. Modern browsers mark websites without SSL as unsafe, which can negatively impact traffic and reputation.

Reliable data encryption
An SSL certificate ensures the security of information transmitted between the website and the user. All data, including passwords and payment information, is encrypted and protected from interception by third parties.

Trust of users and browsers
Modern browsers like Chrome and Firefox mark websites without SSL as not secure. Having HTTPS increases visitor trust and improves the user experience.

F.A.Q.
| What is the main feature of the Sectigo Multi-Domain Wildcard certificate? | ||||||||||
This is the most flexible tool in the Sectigo product line. It combines two technologies: Multi-Domain (SAN) and Wildcard. This allows you to secure completely different domains (e.g., site.com, my-app.net, service.org) and all their top-level subdomains in a single certificate. | ||||||||||
| How many domains can be included in one such certificate? | ||||||||||
The basic package typically includes three domains (FQDNs), but the certificate technically supports extensions for up to 250 different domain names. You can activate subdomain protection for each of these. | ||||||||||
| How does subdomain protection work in a multi-domain certificate? | ||||||||||
For each domain in the SAN (Subject Alternative Name) list, you specify a mask with an asterisk, for example, *.site.com. This automatically enables encryption for shop.site.com, api.site.com, and any other subdomains of this name. | ||||||||||
| Who benefits from purchasing Sectigo Multi-Domain Wildcard? | ||||||||||
It is indispensable for owners of large site networks (PBN), web studios supporting client projects, and companies with a diversified infrastructure (different brands or regional sites on different domains). | ||||||||||
| Does this certificate make server administration easier? | ||||||||||
Yes, and that's its main advantage. Instead of monitoring the expiration dates of 10 or 20 different SSL certificates, you manage a single certificate file and a single renewal date for your entire network of resources. | ||||||||||
| Do I need to undergo Organization Validation (OV) for this type of SSL? | ||||||||||
This certificate is a DV (Domain Validation) certificate. This means that validation is as simple as possible: via email, DNS records, or HTTP files for each specified domain. No paperwork is required. | ||||||||||
| Is it possible to add new domains to a certificate after it has been issued? | ||||||||||
Yes, you can add additional domains or subdomains at any time during the certificate's validity period through the reissue process. | ||||||||||
| Is this SSL compatible with cloud services and CDN? | ||||||||||
Sectigo Multi-Domain Wildcard is fully compatible with Cloudflare, Amazon Web Services (AWS), Microsoft Azure, and most popular CDNs, making it an excellent choice for cloud applications. | ||||||||||
| Does the certificate support mail server security? | ||||||||||
Yes, you can use it to secure IMAP, POP3, and SMTP connections. Thanks to SAN support, you can include mail.domain.com and smtp.other-domain.net and ensure their security. | ||||||||||
| What is the warranty coverage from Sectigo for this model? | ||||||||||
This professional solution comes with a $250,000 insurance guarantee, confirming the CA's high level of confidence in the security of its encryption nodes. | ||||||||||
| How is this certificate displayed in browsers? | ||||||||||
Visitors will see the familiar "gray padlock" and the HTTPS protocol. When viewing your certificate information, the "Subject Alternative Name" field will list all your secured domains. | ||||||||||
| Can it be used for IP addresses? | ||||||||||
No, this certificate is intended exclusively for domain names and their subdomains. This model does not provide protection for public IP addresses. | ||||||||||
| Is a Dedicated IP required for each domain? | ||||||||||
Thanks to SNI (Server Name Indication) technology, modern servers allow you to install a multi-domain certificate on a single IP address for all your sites, which saves hosting resources. | ||||||||||
| How secure is it to store all domains in one certificate? | ||||||||||
It's completely secure. AES-256 encryption is used, and each domain is independently verified before being included in the overall chain. | ||||||||||
| What is the savings compared to purchasing individual Wildcards? | ||||||||||
Purchasing a single Multi-Domain Wildcard is typically 40-60% cheaper than purchasing three or four individual Wildcard certificates. Plus, you save time on installation and renewal. |
