SEPPmail
Protect confidential emails. Keep collaboration straightforward.
Proposals, contracts and personal information need to reach the right recipients securely. SYNEDAT helps integrate SEPPmail with your email environment and establish clear rules for confidential communication. From selection to operations, we plan message routing, recipient access and responsibilities with your IT team.
How your teams benefit
Control confidentiality
Agreed policies define which messages are encrypted and how exceptions are handled.
Enable external communication
Recipient journeys are tested with typical customers and business partners, including first access and secure replies.
Make administration accountable
Certificates, keys, rules and support tasks have defined owners and documented maintenance procedures.
Choose the right capabilities and methods
Encryption, digital signatures and large file transfer serve different purposes. We define the required scope around your communication flows and specify modules and licenses in the proposal.
| Capability / method | Everyday value | Test in the pilot |
|---|---|---|
| Secure E-Mail Gateway | Centrally encrypt and decrypt messages using methods such as S/MIME or OpenPGP. | Which messages need protection, and what happens when keys are missing or delivery fails? |
| Digital signatures and certificates | Enable verification of sender authenticity and message integrity, with central certificate management. | Are issuance, renewal, revocation and ownership defined for the relevant mailboxes? |
| GINA | Support protected communication with external recipients who do not use their own encryption solution. | Do registration, authentication, reading and replies work for the intended recipient groups? |
| Large File Transfer (LFT) | Provide large files through a controlled, protected exchange. | Which sizes, retention periods, storage resources and reply channels are needed? |
Our services from assessment to ongoing support
Assess your email environment
We review domains, email services, sending applications and recipients to produce a mail-flow plan, prioritized protection rules and a focused starting scope.
Explore the related service: Assess your email environmentConnect Microsoft 365 and existing systems
We plan connectors, routing and policies for the agreed environment. External recipients, mobile access and failure scenarios are tested in the pilot.
Explore the related service: Connect Microsoft 365 and existing systemsIntroduce certificates and user workflows
We agree key and certificate procedures, configure recipient journeys and explain the workflow using representative messages.

| Operating model | Suitable focus | Clarify before deciding |
|---|---|---|
| SEPPmail.cloud | For teams seeking a provider-operated service integrated with their email environment. | Subscribed services, processing location, retention, contract, availability and your team's remaining tasks. |
| Your own gateway environment | For organizations seeking to shape infrastructure, key management and operational procedures themselves. | Supported deployment, capacity, resilience, updates, backup and ownership. |
Start with a specific communication use case
SMEs · confidential customer communication
One team pilots contract delivery to a limited recipient group. Clear encryption triggers and a working reply path are the priorities.
Enterprise · multiple domains and departments
Shared policies are coordinated with exceptions for business applications and external partners. A pilot tests routing, roles, certificates and operations across teams.
Illustrative images of collaboration and IT operations. Examples describe possible project scopes.
Turn requirements into a practical starting point
Define the scope
Prioritize domains, mailboxes, senders, recipient groups and required capabilities.
Pilot and acceptance
Use test data to check delivery, receipt, signature verification, external replies and agreed failure cases.
Deploy and hand over
Approve policies, train teams and document operational tasks and subsequent rollout phases.
A proposal that fits your email operations
Tell us your number of domains and mailboxes, your email service and two typical communication use cases. We define assessment, licenses, integration, training and ongoing support separately. An existing installation can be the starting point, as can a new deployment.
Discuss your SEPPmail projectFrequently asked questions about SEPPmail
Is TLS transport encryption enough?
TLS protects connections between participating systems. S/MIME or OpenPGP encryption protects the message itself. The required approach depends on recipients, infrastructure and your requirements; we define policies for your actual mail flows.
Does every recipient need a certificate?
S/MIME or OpenPGP requires suitable certificates or keys. GINA offers another route for recipients without their own encryption solution. Registration, authentication and replies should be tested with your recipient groups before rollout.
How does a digital signature differ from an email footer?
A digital signature supports verification of sender authenticity and message integrity. A footer contains items such as contact details or legal notices. Both may matter, but they serve separate purposes.
Can SEPPmail work with Microsoft 365?
SEPPmail can be integrated with Exchange Online. We review connectors, routing, sender policies and existing protection features. The integration approach follows your architecture and is tested with representative messages.
How should we manage certificates and keys?
Define issuance, assignment, renewal and revocation, as well as access, backup and recovery. We account for the selected certificate authority and the capabilities supported by your product option.
How do we choose between cloud and our own gateway?
We compare infrastructure, operational resources, integrations and requirements for data processing and availability. This informs a model with clear responsibilities. Contractual and service scope are agreed before commissioning.
What file sizes does Large File Transfer support?
This depends on the product scope, license, storage, configuration and operating model. We agree required sizes and retention periods and test representative files. Unlimited transfer capacity is not assumed.
Does email encryption replace phishing protection?
Encryption protects confidentiality; filtering and other controls address different risks. We align SEPPmail with existing spam, malware and identity protection. Additional filtering services are assessed separately where needed.
Does SEPPmail automatically meet every privacy requirement?
A product alone does not replace assessment of your processing and workflows. Configuration, access rights, contracts and operational procedures must fit the intended use. SYNEDAT supports implementation and documented testing of agreed requirements.
Can we start small or improve an existing installation?
Yes. A limited pilot with selected mailboxes and recipients suits a new deployment. For existing systems, we begin with policies, certificates, mail flow and operational documentation, then prioritize the next steps.
