Company Validated SSL certificate

OV SSL - more trustworthy than domain validation SSL

The CA verifies domain ownership as well registered business documents and other legal documents related to business.
The domain is verified by sending an e-mail message to the selected e-mail. According to the rules there are fixed addresses to choose from admin@, administrator@, webmaster@, hostmaster@ or postmaster@. Instead of e-mail confirmation, alternative validation offers inserting a TXT record into a DNS domain zone. We support DNS alternative verification method and is set in the order detail.

How long it takes to get the Certum Trusted WildCard certificate

The Certificate Authority performs light business authentication

The Certification Authority verifies domain ownership as well registered business documents and other legal documents related to business. If the certification authority has sufficient documentation, the domain is confirmed and telephone verification is carried out, it takes 2 to 5 days to issue the certificate. If the authority can not confirm the legal, operational and physical existence of the company, the verification time is extended.

Domains Secured

WildCard SSL can secure unlimited sub-domains

Wildcard SSL certificates can secure your fully qualified domain name and its sub-domains.
In the case of a request to secure a 2nd level domain, i.e., a SAN extension will be added for a separate domain, i.e. Thus, one Certum Trusted WildCard certificate will secure the website for the main domain and all its subdomains at the same time. On the other hand, in case of a requirement for security of subdomains of the 4th and n-th level, for example, it is always necessary to obtain a separate WildCard SSL certificate This then again allows HTTPS security for unlimited domains at that level.

Renewing your certificate

You need to renew Certum Trusted WildCard certificate before it expires

You can start renewing an expiring SSL certificate 30 days before it expires. It is recommended not to leave the renewal to the last minute, unused validity of the certificate will be added to the renewed one.
You can renew your Certum Trusted WildCard certificate with us without any problem even if you originally ordered it from another supplier. We always have better prices than the certification authority!

REISSUE certificate

Unlimited free reissues for orders at our store

During the validity of the certificate, you can re-generate the certificate at any time free of charge. This is called REISSUE and is useful in case you do not have a private key for migration to another server or the keys have been deleted and there is no backup. Reissue is possible with a new request that contains the same data as the initial order.

Note i: Best practices are to generate a new certificate signing request (CSR) when reissuing your SSL/TLS certificate. Generating a new CSR creates a new, unique key pair (public/private) for the reissued certificate.
Note ii: It is not possible to reissue SSL while it is processing or another reissue request pending.

Multi-Year Certificates

In order to provide you the lowest cost per year, we offer 2-5 year certificate packages

As of 1 September 2020, Apple, Google and Mozilla browsers and devices do not accept new SSL/TLS certificates that have a lifetime of more than 398 days. To comply with the latest security requirements, multi-year SSL certificates are issued for 1 year (max. 398 days). You'll need to re-issue the certificate once per year. We'll send you email notifications starting 30 days before expiration. Of course, REISSUE is free of charge. Plus you can reissue your certificate at any time and as many times as you like!

After the certificate is issued, you cannot shorten the validity period, request a refund of the unused period or change the domain name! If you decide to get an SSL certificate for 3 years or more, we recommend that you first consider whether you will need it for the entire period.

Note i: Re-issue requires revalidation.
Note ii: You can insert new CSR or use last one during reissue.
