The TC Gateway Certificate is designed for customers who want to make their business e-mail communication secure and trustworthy.

The TC Gateway Certificate is a certificate on which the name of the company and the e-mail address of the gateway are entered; i.e. the certificate confirms that the gateway or the sender's address belong to the company. As the TC Gateway Certificate is assigned to an application or server, as well as an e-mail address, it is possible to send signed e-mails via a mail gateway with the same mail address – e.g. info@company_XYZ.com. In this way it is also possible to receive incoming encrypted e-mails; for this the senders simply need the public key of the certificate.

With a TC Gateway Certificate you sign your e-mails automatically and show your communication partners that trust and security are important to you. The digital signature enables your partners to be sure that your e-mail has reached them unchanged, and that it does in fact come from your company. As a result, your e-mails are also clearly distinguished from SPAM or phishing e-mails.
