Why external email communication turns into a security problem
Secure email delivery often fails on technical reality: the recipient system is unknown and the capabilities on the other side vary.
Different technical prerequisites
Private customer, law firm or corporate group: you cannot assume the other side uses PGP or S/MIME. Unencrypted mail risks GDPR violations and data loss.
Manual workarounds raise risk and effort
Pack a password protected ZIP file and send the password by text message afterwards? Such breaks cost time, are error prone and undermine any IT governance.
Secure external communication without a break in the workflow
The right path for every recipient
Our platform detects automatically whether the recipient supports encryption. If it does, delivery runs seamlessly by S/MIME or PGP in the background.
Central control instead of case by case
Take the load off your staff. Central policies define by rule (by domain or label, for example) when a message must be transferred securely.
Fallback without keys
Bietet der Empfänger keine Verschlüsselung, stehen zwei schlüssellose Wege bereit: das Secure Message Portal für interaktive Kommunikation oder die PDF-Verschlüsselung für maximale Einfachheit.
Secure Message Portal
Interaktive verschlüsselte Kommunikation im Browser. Der Empfänger authentifiziert sich, liest die Nachricht und kann direkt verschlüsselt antworten – in Ihrer Corporate Identity.
Portal entdeckenPDF-Verschlüsselung
Vertrauliche E-Mails werden als AES-256-verschlüsseltes PDF zugestellt. Der Empfänger braucht nur einen PDF-Reader – kein Portal, kein Login, keine Software-Installation.
PDF-Verschlüsselung im DetailWhere this solution is particularly relevant
Law & finance
Share contracts, client data, balance sheets and pleadings with any external recipient, without compliance risk.
Healthcare
Send patient records, sensitive diagnoses and findings securely to colleagues, laboratories and patients themselves.
HR & recruiting
Arbeitsverträge, Gehaltsabrechnungen und sensible Bewerberdaten beidseitig absolut datenschutzkonform versenden und empfangen.

No keys of your own?
This is how delivery works for recipients without a crypto infrastructure of their own.
Notification
The recipient receives a regular email, branded in your corporate identity, with a secure link to the message.
Authentication
After the click the user authenticates, by SMS one-time code, password or M365/Google SSO for example.

Noch einfacher: PDF-Verschlüsselung
Nicht jeder Empfänger möchte sich in einem Portal anmelden. Mit der PDF-Verschlüsselung erhalten Empfänger vertrauliche E-Mails als passwortgeschütztes PDF – AES-256-verschlüsselt, Passwort über separaten Kanal. Kein Login, kein Browser-Portal, nur ein PDF-Reader.
