Enterprise Email Encryption
GDPR compliant email encryption gateway for enterprises
– encrypt emails easily at any time with anyone –
effective protection against economic and industrial espionage
Z1 SecureMail Gateway provides security and compliance for all your emails. It is highly automated, fail-safe and encrypts emails faultlessly. Secure email is easily realized with business contacts or end customers. Z1 SecureMail Gateway works with any counterpart whether it is gateway to gateway encryption or secure email delivered from your gateway to a private webmail account. You get highest security standards and easy compliance including the EU GDPR naturally.
Easy Mail Compliance (EU GDPR)
Don’t worry about personal liability in IT compliance issues. Centrally configurable security policies (Z1 Policies) make sure you don’t need to rely on the judgement of individual employees when dealing with highly sensitive information. You don’t even need to invest in any IT Security awareness training for confidential email exchange. With Z1 SecureMail Gateway policies there won’t be any EU GDPR compliance violations due to accidental misuse or forgotten encryption operations. Z1 policies ensure that all users that deal with personal data can only send encrypted messages. All security actions are traceable through always-on logging and monitoring in the graphical administration web interface.
Industrial Espionage Defense
Z1 SecureMail Gateway provides you with military grade encryption, enabling effective protection against industrial espionage and foreign governmental spy programs. The gateway encrypts the actual email content not only the transport channel. Even if providers are obliged to pass your data to secret agencies all they can provide is illegible text: encrypted data.

You get maximum protection paired with efficiency and great usability, in a nutshell: State of the Art email encryption – made in Germany.
How does it work?
Each email is individually encrypted according to the recipient’s capabilities.
Email Encryption and Signature
Z1 SecureMail Gateway comes as a virtual email encryption appliance which integrates seamlessly into an existing email infrastructure. As an SMTP proxy it processes the entire company-wide email traffic. The Z1 SecureMail Gateway operates as a virtual mail room – processing incoming and preparing outgoing mail. It encrypts and signs outgoing mail whilst decrypting and validating the signature of incoming items. Suspicious emails are automatically blocked and the internal recipient informed. The complete email processing is performed according to ‘Z1 Policies’ which can be fully configured using the web-based administration interface. Z1 SecureMail Gateway works silently and transparently in the background. Sending and receiving emails remains the same for employees.
Certificate and Key Management Challenge
Z1 SecureMail Gateway uses the popular worldwide PKI standards S/MIME and OpenPGP for email encryption and digital signing. Z1 SecureMail Gateway automatically and centrally encrypts and decrypts all in- & outbound emails whilst at the same time managing all the keys for internal and external users. This solves the main challenge of secure email encryption solutions: the efficient operation of PKI based email encryption.
For further information about keys and certificates download our White Paper: Secure email in times of rising mobile communication – Applied cryptography: Certificates, Gateways & End-to-End Encryption.
Internal Certificates and Keys
Managed PKI – automated S/MIME certificate procurement
Certificates for internal users and domains can be obtained at all officially recognized Certificate Authorities. With our Z1 KeyManager and optionally available CA Connectors you can automate the purchase process with a selection of Certificate Authorities such as SwissSign or Quo Vadis. This guarantees a professional and efficient certificate management. This one stop shop approach reduces your adminstration and accounting efforts for your SMIME email gateway.
Keys for internal users can also be created and signed with the aid of the OnBoard CA. Existing keys can be simply imported and activated and used directly for encryption and/or digital signing. The Lifecycle management for keys and certificates is highly automated and efficient.
External Certificates and Keys
The integrated Z1 CertServer component independently performs the fetching, storing, validation and administration of certificates for all external communication partners. Z1 SecureMail Gateway is delivered with a predefined editable set of the most important Certificate Authorities and LDAP directories.
TLS 1.3, VPN and De-Mail
Encrypted Channels for the secure transfer of email have become well established. A German technical guide from the ministry for security in information technology sets the minimum standard for federal agencies TLS 1.3. Z1 SecureMail Gateway supports TLS according to the current standard. Other encryption methods for secure channels for email transfer are supported.
VPN Connections for continuous communication can be configured via the administration interface.
German De-Mail customers can use our special optional extension De-Mail-Connector. This enables the use of Z1 SecureMail Gateway as a De-Mail Gateway. Zertificon is not a De-Mail Service Provider. Further information about De-Mail (only in German language) can be found here.
Z1 MyCrypt Gateway Companion
Z1 MyCrypt Gateway Companion

Z1 MyCrypt Gateway Companion is available as Outlook add-in for Z1 SecureMail Gateway.
The use of the plugin is optional. It will not run without a Z1 SecureMail Gateway connection however.
