DigiCert.
Encryption without compromise.

Yes, all conventional operating systems for newer computers, tablets and mobile phones support TLS/SSL protocols. The TLS/SSL certificates from DigiCert offer the highest root availability for 99.9% of all current web browsers, common operating systems and mobile devices.

If you have any questions about compatibility with devices using outdated operating systems, please contact our Support Team.

With a Multi-year Plan, DigiCert TLS/SSL certificates can be purchased with a validity period of up to 36 months at the same price conditions. 

The respective certificate is always valid for 397 days. Depending on the purchased validity period – 24 or 36 months – a free reissue must be carried out and the newly-generated TLS/SSL certificate must be exchanged on the server before the validity period of 397 days expires. This can be done at the earliest 90 days before and at the latest one day before the end of the respective 397-day period. 

Yes, absolutely. A CSR (certificate signing request) is an encrypted file that enables you to transmit your public key and other identifying information about your company and the domain name to DigiCert. It is also called the CSR key.

The CSR is generated on the server on which is will later be installed. All data required by DigiCert to issue the certificate must be entered for this. The following information is required when creating the CSR:

• Common name (e.g. www.example.com)
• Name and location of the company (country, state/province, city)
• Key type (usually RSA)
• Key length (minimum 2048 Bit).

Please keep the CSR key at hand when buying DigiCert certificates in AutoDNS. 
 

Online seals catch the attention of users.

The validation of DigiCert S/MIME certificates is as strong as that for TLS/SSL certificates. DigiCert S/MIME certificates are generally issued via a digital ID for individuals and departments in a company.

The DigiCert S/MIME Class1 is subject to domain or email validation (DV). Confirmation of the certificate is carried out via the email address. The certificate does not include any other information for the recipient.

The S/MIME Premium and Digital Signatur Plus certificates are organization validated (OV). This entails authentication of the organization by verifying ownership via a call to the human resources department using a telephone number from a public listing as well as information from the commercial registry. The information about the company is included in the certificate and can be viewed by recipients.

In this way, sensitive data is effectively protected, manipulation is prevented and the sender's integrity is clearly established.
