End-to-End Email & Data Protection

End-to-End Email & Data Protection –
Confidentiality and integrity for email and files — without operational overhead

End-to-end encryption protects the content of emails and files from unauthorized access—independent of servers, transport paths, archives or backups. Combined with personal digital signatures, it ensures authenticity, integrity, and non-repudiation of business communication. For many organizations, the real barrier is certificate handling at scale. A modern solution therefore combines encryption with automated certificate workflows to deliver secure communication that users can adopt and IT can operate.

Use Cases

Ende-zu-Ende E-Mail-Verschlüsselung

Secure email communication (internal and external)

Protect internal and external email content with end-to-end encryption and signatures—beyond gateway and TLS controls.

Digital signature solutions

Secure file exchange and storage protection

Encrypt and sign files to protect sensitive data across transfer paths, shared storage and long-term archives.

Signed communication for integrity and accountability

Use personal signatures to verify sender identity, detect tampering, and provide accountability.

Classified communication with scalable certificate automation

Support high-security and compliance-driven environments with standards-based encryption and scalable certificate automation.

Use Case Challenges

Transport security is not content security

  • TLS/gateways protect transmission but not content in mailboxes and archives
  • Content remains exposed in storage, backups, and endpoints

Manual certificate handling blocks scale

  • Manual issuance and renewal prevents scaling beyond pilots
  • Operational overhead and support effort increase without automation

Interoperability requirements

  • Standards-based interoperability is required across organizations
  • S/MIME and OpenPGP must be supported in heterogeneous environments

User Adoption

  • Adoption depends on seamless integration and minimal training
  • Security must fit existing workflows

Key supporting points

Transport security protects the channel, not the content in mailboxes/archives—content-level protection closes this gap.
Automated certificate lifecycle management removes the main barrier to scaling end-to-end encryption deployments.
Standards-based interoperability (S/MIME and OpenPGP) supports partner communication and mixed client environments.

Eviden Solution – Automated End-to-End Email & File Protection

Eviden provides end-to-end protection for email and files with GreenShield. GreenShield encrypts content and applies personal signatures to guarantee confidentiality, integrity and verifiability. For enterprise rollouts, GreenShield Enterprise combines the proven client integration with automated workflow and certificate lifecycle automation, so certificates are requested, distributed, renewed and revoked without manual effort. The solution is based on S/MIME and supports OpenPGP; it integrates into standard user environments such as Microsoft Outlook and HCL Notes.

Solution Components

  • Eviden GreenShield — end-to-end encryption and digital signatures for email and files.
  • GreenShield Enterprise — automated workflow and certificate lifecycle management to scale deployments.
  • PKI / CA integration — connect internal or external certificate authorities as trust foundation.
  • Optional: cryptovision SCinterface — hardware-backed keys via cards/tokens/TPM where required.

Result: confidential and verifiable communication, reduced risk from BEC and insider threats, and scalable rollouts with minimal admin effort.

Frequently Asked Questions




What is end-to-end email encryption?

End-to-end encryption ensures only sender and recipient can read content—independent of servers, transport paths, archives or backups.




Why is TLS not sufficient for email security?

TLS protects transmission but not stored content in mailboxes, archives or backups.




Which standards are supported?

Common standards include S/MIME and OpenPGP for interoperable secure communication.




How do digital signatures improve email security?

They provide integrity, authenticity and non-repudiation for messages and files.




What is the biggest barrier to scaling encryption?

Manual certificate handling—automation is required to deploy securely at enterprise scale.




Does it integrate into user environments like Outlook?

Yes. Standards-based solutions integrate into common clients such as Microsoft Outlook and HCL Notes.
