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 distinguishes GeoTrust Premium Wildcard from budget Wildcard solutions? | ||||||||||
This certificate belongs to the business segment. Key differences include issuance infrastructure (more reliable root certificates), extended insurance, and priority processing of OCSP requests, which directly affect the connection speed in the browser. | ||||||||||
| How many subdomains can be protected under one license? | ||||||||||
There are no restrictions on the number of first-level subdomains. You can protect *.domain.com, which ensures security for mail.domain.com, vpn.domain.com, billing.domain.com, and any other names created based on your main domain. | ||||||||||
| Does GeoTrust Premium Wildcard protect the main domain without 'www'? | ||||||||||
Yes. When issuing a certificate for *.yourdomain.com, the main domain (Apex Domain) yourdomain.com will also be protected, eliminating security errors when users access through the site's root. | ||||||||||
| How quickly is this certificate issued? | ||||||||||
Despite the 'Premium' status, this is a domain-validated (DV) certificate. The process is automated and takes 5 to 15 minutes after domain ownership is confirmed through the chosen method (Email, DNS, or file). | ||||||||||
| Is a trust seal provided with this SSL? | ||||||||||
Yes, you receive the dynamic GeoTrust True Site Seal. It contains a timestamp and security confirmation from GeoTrust, visually increasing user trust on registration and payment pages. | ||||||||||
| Does the certificate support operation with multiple physical servers? | ||||||||||
Yes. GeoTrust Premium Wildcard comes with a license for an unlimited number of servers. You can use the same certificate and private key on the main server, mirrors, and load balancers. | ||||||||||
| What is the insurance amount provided for this model? | ||||||||||
GeoTrust Premium Wildcard offers one of the highest guarantees in the DV class—$500,000. This confirms the certification authority's readiness to be responsible for the reliability of its encryption. | ||||||||||
| Can this SSL be used on subdomains of different levels? | ||||||||||
A wildcard certificate works at the level where the ‘asterisk’ is placed. If the certificate is issued for *.domain.com, it will not protect test.dev.domain.com. A separate wildcard for the needed level will be required for such purposes. | ||||||||||
| Is the certificate compatible with mobile devices and smart TVs? | ||||||||||
Yes, GeoTrust roots are recognized by 99.9% of all devices. This includes outdated smartphones, modern gaming consoles, smart TVs, and specific banking equipment. | ||||||||||
| How does GeoTrust Premium Wildcard affect website loading speed? | ||||||||||
Using OCSP Stapling technology and GeoTrust's premium infrastructure reduces the time it takes to verify the certificate. This minimizes delays before your website pages begin to load. | ||||||||||
| What will happen if I lose the private key? | ||||||||||
In your ProHoster account, you can initiate a free reissue procedure. You will need to generate a new CSR request and validate the domain, after which you will receive a new certificate file. | ||||||||||
| Does the certificate support modern ECC algorithms? | ||||||||||
GeoTrust keeps up with the times and supports not only standard RSA keys (2048 bits) but also more efficient elliptic curve (ECC) algorithms, which provide the same level of protection with lower server resource consumption. | ||||||||||
| Is a fixed IP address required to install GeoTrust Wildcard? | ||||||||||
No, thanks to SNI technology support on web servers, you can install this wildcard certificate even on shared IP virtual hosting. | ||||||||||
| Can this certificate protect internal company email services? | ||||||||||
Absolutely. It is well-suited for encrypting traffic in Microsoft Exchange, Postfix, Exim, and other mail servers that use subdomains (e.g., imap.site.com, smtp.site.com). | ||||||||||
| What are the requirements for a CSR request for GeoTrust Premium Wildcard? | ||||||||||
When generating a CSR request, be sure to enter the domain name in the 'Common Name' field using the format *.your-site.com. Other fields (city, organization) can be filled out in the standard way, as they are not thoroughly checked for DV certificates. |
