How to add domains in GeoTrust QuickSSL Premium SAN

A feature of the certificate GeoTrust QuickSSL Premium SAN is that all the protected addresses (SAN — Subject Alternative Names) must be specified in the certificate signing request (CSR) or indicated in the control panel when issued.

Step 1: Generate a CSR request using OpenSSL

To protect multiple domains or subdomains, it is easiest to use the OpenSSL command line. You need to create a configuration file (for example, san.cnf):

Bash

[req]
distinguished_name = req_distinguished_name
req_extensions = v3_req
prompt = no
[req_distinguished_name]
C = NL
ST = Meppel
L = Meppel
O = My Company Name
CN = main-domain.com
[v3_req]
subjectAltName = @alt_names
[alt_names]
DNS.1 = main-domain.com
DNS.2 = *.main-domain.com
DNS.3 = second-domain.net
DNS.4 = *.second-domain.net

Then execute the command to generate the key and CSR: openssl req -new -out res.csr -newkey rsa:2048 -nodes -sha256 -keyout res.key -config san.cnf

Step 2: Submitting the CSR and Activation

  1. Copy the contents of the file res.csr into the order form on the website ProHoster.
  2. The GeoTrust system will automatically recognize all additional domains specified in the SAN.
  3. Complete the validation (DV) process for unstructured output the main domain from the list.

Step 3: Adding domains during use (Reissue)

If you need to secure a new domain after the certificate has been issued:

  1. Log in to your ProHoster account in the SSL management section.
  2. Click the button «Reissue».
  3. Generate a new CSR with the updated list of domains (as in Step 1).
  4. Confirm ownership of the new domain. After that, GeoTrust will issue an updated certificate file.

Why do you need an SSL certificate?

An SSL certificate not only encrypts the data transfer between the user and the site but also increases trust from visitors and search engines. Modern browsers mark sites without SSL as unsafe, which can negatively impact traffic and reputation.

0002 layer 7

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

0003 layer 6

Modern browsers, such as Chrome and Firefox, label sites without SSL as unsafe. Having HTTPS increases visitor trust and improves the perception of your website.

0004 layer 5

You will find instructions on how SSL is a ranking factor in search engines. A secure website earns more trust, positively impacting its Google rankings, traffic, and conversion rates.

I’ve been renting a VPS here for several months now for a personal project. The setup was fast, and I got all the details by email right away. The connection speed is steady, and the server hasn’t gone down once. I contacted support twice – they replied quickly and helped fix an SSL issue. Everything works fine, and I’m satisfied with the service overall.

We needed a fast solution for a support node for our new project development team. Didn’t have much of an option at that moment, so had to be both fast and precise. We have chosen this company from a big list of Hosting Companies and never even once thought of switching to a new one. Great support, nice technical team, and good environment. Recommend

Been using ProHoster for a bit, does the job without headaches. No sudden crashes, speed is fine, and the control panel isn’t a mess. Support replies when needed, not just with copy-paste answers, and actually helps. Prices are reasonable, no weird surprises in billing, and setup was smooth. If you need hosting that works without drama, this one’s worth checking out.

Frequently Asked Questions

What does the SAN prefix in the name of this certificate mean?

SAN (Subject Alternative Name) is a technology that allows securing multiple completely different domain names with a single certificate. Unlike standard SSLs, GeoTrust SAN allows you to include different FQDNs (for example, mysite.com, my-portal.net, and service.io) under one license.

How many domains are included in the base price of GeoTrust QuickSSL Premium SAN?

The standard package includes protection for 4 domain names (1 primary + 3 additional SAN fields). This makes it one of the most cost-effective offers for owners of small website networks or multi-brand platforms.

Can this certificate be used to protect subdomains?

Yes, you can specify specific subdomains in the SAN fields (for example, blog.site.com, dev.site.com). However, if you need protection for an unlimited number of subdomains, it's better to consider the Wildcard version.

Is company document verification required for GeoTrust SAN?

No, this is a DV (Domain Validation) certificate. The validation is based solely on the technical parameters of domain ownership. This allows for the issuance of a multi-domain business-class certificate in just 5 to 15 minutes.

How does validation work if the domains are with different registrars?

Each domain listed in the SAN must undergo separate validation. You can choose a convenient method for each: via a verification file on hosting, a CNAME record in DNS, or email confirmation (admin@...).

Does GeoTrust SAN work with Microsoft Exchange?

Yes, it is the ideal solution for Microsoft Exchange and Office Communications servers. The SAN (also known as UCC) technology allows you to protect autodiscover, owa, and your primary mail domain simultaneously.

What is the encryption key length for this product?

GeoTrust uses the industry standard: a key length of 2048 bits, data encryption up to 256 bits using SHA-2 signing algorithms. This ensures maximum resistance to hacking.

Can new domains be added after the certificate is issued?

Yes. If you need to change the list of protected addresses, you can initiate the free reissue procedure. The old certificate will be revoked, and the new one will contain the updated list of your SAN domains.

Does the number of domains in SAN affect website loading speed?

Thanks to GeoTrust's optimized infrastructure and OCSP Stapling technology, certificate authentication occurs instantly, regardless of how many names are included. This does not affect content loading speed.

Will the trust seal appear on all protected domains?

Absolutely. You can install the dynamic GeoTrust True Site Seal on each of the sites listed in the certificate. This visually confirms security for visitors to all your resources.

What financial responsibility does GeoTrust have?

The guarantee amount is $500,000. This is the insurance sum that is paid in the event of financial damage to the user due to a technical failure by the certification authority.

Can local server names (internal domains) be protected?

According to the current CA/B Forum rules, the issuance of certificates for non-public domain names (e.g., server.local) is prohibited. All names in GeoTrust SAN must be public and accessible externally.

Is the certificate compatible with mobile browsers?

GeoTrust QuickSSL Premium SAN has a compatibility rate of 99.9%. This includes not only desktop browsers but also mobile operating systems (iOS, Android), various smart devices, and payment gateways.

Do I need to reinstall the certificate on all sites when reissuing?

Yes, since a new certificate file (CRT) is generated upon reissuance, it must be updated on all servers where the domains from this SAN list are used.

Why is GeoTrust SAN better than multiple free SSLs?

Centralized management (one expiration date), professional technical support, high financial guarantees, and brand recognition are key factors that make paid multi-domain SSL a more reliable solution for businesses.
