Domain Validated SSL certificates

SSL certificates issued in minutes

The applicant for the SSL certificate 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@. We recommend creating one of the addresses, or having it set as an alias, ev. use the domain basket and retrieve the confirmation e-mail from it.
Instead of e-mail confirmation, alternative validation offers inserting a TXT record into a DNS domain zone or a text file into the data space on the server (FTP). We support both alternative verification methods and are set in the order detail.

Note i: It is not possible to send a validation email to a personal address e.g.
Note ii: WildCard SSL supports only e-mail or DNS validation.

Company Validated SSL certificates

Company Certificate increasing user trust in your website and its credibility

Verification of the applicant for an OV/EV SSL certificate is based on the CA/B Forum guidelines and each CA must follow the set process.
First, the domain is validated as for domain SSL certificates. Next, the existence of the company is verified and the address is checked. If the Authority can not confirm legal, operational and physical existence the validation time is extended. The final validation is done by a phone call to a phone number that is traceable in public authority databases.

CA Certum performs standard company validation. You can find info about "The verification process and the documents required after purchasing a Certum SSL Certificate" here:

Note i: It is not possible to send a validation email to a personal address e.g.
Note ii: EV SSL are more consistently validated. In addition to the existence of the company, the applicant (contact) for the certificate is also verbally verified.

Multi-Year Certificates

We offer SSL certificates for up to 5 years in order to provide the lowest cost per year

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 period of validity, ask for a refund of the unused period! If you decide to get a multi-year SSL certificate, we recommend that you consider whether you will use it for the entire period.

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