Maintain control over your data with eperi sEcure
Microsoft Copilot opens up new possibilities for more productive work: summarizing content, analyzing documents, creating text, or finding knowledge faster.
However, many companies are facing a crucial question:
How can Copilot be used without exposing sensitive data to AI systems?
With eperi sEcure, you don’t have to choose between innovation and data protection. The solution protects sensitive content in Microsoft 365 through encryption, while Copilot can still be used for non-sensitive information.
This creates a clear security mechanism:
Copilot remains powerful, while sensitive data stays protected.
Use Copilot Without Exposing Sensitive Data
With eperi sEcure, a clear separation between public information and confidential data is established.
Copilot can continue to be used for all content available in plain text. Sensitive information, on the other hand, remains encrypted and is therefore inaccessible to the hyperscaler’s proprietary AI system.
This architecture ensures that organizations can leverage the benefits of Copilot without compromising their data sovereignty.
Copilot Remains Powerful for Many Use Cases
Research and Document Overviews
Copilot can still be used for requests based on publicly available or non-sensitive information.
Examples:
- Appointment coordination
- Summarizing information from open knowledge sources
- Conducting general research
These functions remain fully available.
Text Corrections and Content Creation
Classic in-app Copilot features such as:
- Text corrections
- Formulierungsverbesserungen
- Content creation
remain fully usable.
Important to note:
When using these features, content is transmitted to Microsoft in plain text. For highly sensitive data, an extended security model is recommended.
Transcriptions and Meeting Recordings
Copilot can continue to process audio and video content, for example for:
- Meeting summaries
- Transcriptions
- Automated minutes
Since these streams are not encrypted, full functionality is maintained.
Automatic Protection of Sensitive Content
As soon as content is encrypted by eperi sEcure, it is automatically protected from access by Copilot.
This applies to:
- Confidential documents in SharePoint
- Sensitive emails
- Teams chats
- Internal knowledge bases
In these cases, Copilot cannot process the content.
The result:
No sensitive information is transferred to Microsoft’s AI systems or external models.
Clear Separation for Maximum Data Security
The approach is deliberately simple and transparent.
| Data Type | Copilot Access |
| Public or non-sensitive information | Available |
| Plain text data | Available |
| Encrypted content | Protected |
This creates a clear security logic:
Copilot continues to deliver results for non-critical content, while sensitive data remains reliably protected.
This separation helps organizations ensure both productivity and compliance.
The Next Step: Using AI Without Losing Data Sovereignty
While this approach makes Copilot secure to use, many organizations are already taking the next step.
You want to use AI for sensitive data as well — without losing control over it.
This is where a new concept emerges:
Confidential AI
Confidential AI: AI for Sensitive Data
Confidential AI enables the use of AI applications on confidential data without exposing it unprotected.
Sensitive information remains encrypted and under the control of the organization
while AI models can perform analysis in a controlled environment.
Typical use cases include:
- Summarizing sensitive documents
- Extracting knowledge from internal data
- Analyzing large document collections
- Intelligent search across enterprise knowledge
The Difference Between Public AI and Confidential AI
Public AI systems like Copilot typically work with plain text data within their platform.
This means:
If sensitive data is encrypted, it remains intentionally inaccessible to such systems.
This protects confidential information but also prevents its use by AI.
Confidential AI closes this gap.
Here, data is processed in a controlled environment while encryption and access control remain in place. It runs in the company’s data center or with a trusted partner in a TEE (Trusted Execution Environment).
Cloud Encryption as the Foundation for Sovereign AI
Confidential AI requires a strong security architecture.
This includes:
- Encryption of sensitive data in the cloud
- Company-controlled encryption keys
- Isolated AI execution environments
- Clear governance mechanisms
With this architecture, organizations can use AI technologies without giving up data sovereignty.
Data Sovereignty in the AI Era
The combination of cloud encryption and Confidential AI enables a new approach to handling sensitive data.
Companies no longer have to choose between:
- Full protection of sensitive data
- Use of modern AI technologies
Instead, both goals can be achieved simultaneously.
Sensitive documents, emails, and knowledge bases remain protected while still being usable in controlled AI environments.
Why Data Sovereignty Is Critical for AI
The use of AI in enterprises is growing rapidly.
Many organizations want to use AI to:
- Make knowledge more accessible
- Support decision-making
- Automate processes
- Increase productivity
At the same time, regulatory requirements for handling data are increasing.
Especially in highly regulated industries such as:
- Financial services
- Insurance
- Healthcare
- Public sector
protecting sensitive information is essential.
Data-sovereign AI architectures make it possible to meet these requirements.
Achieve Sovereign AI with eperi sEcure
eperi sEcure provides the foundation for secure use of modern cloud and AI technologies.
The solution enables:
- Encryption of sensitive data in Microsoft 365
- Protection of confidential content from AI system access
- Secure use of Copilot for non-sensitive information
- Building data-sovereign AI architectures
This allows organizations to drive innovation without compromising security and compliance.
Innovation and Data Security Are Not Opposites
The adoption of AI technologies presents many organizations with a fundamental challenge:
How can innovation and data security be aligned?
With solutions like eperi sEcure, this balance becomes achievable.
Copilot can still be used productively while sensitive data remains protected.
And with Confidential AI, even highly sensitive information can be securely used for AI applications.
