.

Encrypt and sign emails automatically and seamlessly – ensuring full compliance without additional IT effort.

Effortless handling

Users send emails as usual – FTAPI automatically takes care of encryption, decryption, and digital signatures.

Central certificate management

Issuance and administration of S/MIME certificates run automatically in the background – saving time and reducing the burden on your IT team.

100% European data sovereignty

Your data remains secure in German data centres – GDPR- and BSI-compliant, ensuring full compliance and digital sovereignty.

Fully protected email flow.

Always secure and compliant

With FTAPI, emails remain protected at all times – regardless of your recipients’ IT infrastructure. SecuMails secures everyday communication, while the S/MIME add-on complements this wherever certificate-based encryption is required. If the recipient supports S/MIME, encryption automatically follows the standard. Where no infrastructure exists, FTAPI’s proprietary encryption seamlessly takes over.

Ready for the next step?

With FTAPI + S/MIME, you combine maximum security, ease of use, and full compliance.

Secure communication in regulated industries. Protect sensitive data reliably – without unnecessary complexity.

Secure communication with state and federal authorities

Institutions such as Job Centres, the Federal Employment Agency, or the Federal Office for Migration and Refugees (BAMF) mandate S/MIME as the binding standard for electronic communication. Public authorities and institutions that regularly exchange sensitive social data with these bodies are therefore required to encrypt their email communication using S/MIME.

S/MIME

Secure transmission of sensitive patient data to funding bodies

In the billing of healthcare services, the use of S/MIME is mandatory. Hospitals, clinics and preventive care institutions must transmit sensitive patient data via S/MIME to health insurance providers and funding bodies such as the German Pension Insurance in order to meet statutory data protection and security requirements.

S/MIME

Regulatory-compliant communication with institutions

Whether in lending, risk reporting or the transmission of account information – financial institutions require communication that is both demonstrably secure and authentic. As a rule, S/MIME in combination with an electronic signature is prescribed as the binding standard to ensure security and legal validity.
