Security

ONYVEN is a German company. We build for enterprises in regulated industries, so security is designed in from the start, not added later.

  • Never used to train AI

    Your documents are used for your work only. No AI model is ever trained on them.

  • Humans stay in control

    AI reads, rules decide, your team approves. Nothing reaches your systems without your say.

  • Built for GDPR and KVKK

    Every customer gets a data processing agreement, and Turkish companies the KVKK standard contract.

  • Full audit trail

    Every document, decision and export is recorded and traceable.

01 · Data protection


Hosted in the EU, kept apart from every other company, and deleted when you say so.

  • EU hosting

    Your data is hosted and processed on Microsoft Azure within the EU, under European data protection law.

  • Encrypted in transit and at rest

    Your data is TLS-encrypted whenever it moves and stored encrypted wherever it rests.

  • Strict data isolation

    Each company's data is kept separate from every other company's, in the application and again in the database.

  • Retention on your terms

    You set how long we keep your data and when it is deleted. If you leave, your data is returned to you.

02 · Responsible AI


The model extracts information. It has no access to your systems, and it cannot act on its own.

  • The AI never acts

    The AI model cannot send messages, change records or browse the web. Every action is taken by rules you set or by a person.

  • Validated output

    Every result is checked against a fixed data model before anyone sees it. Anything that does not fit goes to a person.

  • Protection against manipulation

    Documents that try to instruct the AI cannot make it act. Reading and acting are kept apart by design.

  • Enterprise AI terms

    We work with leading AI models under enterprise terms. Model providers never use your documents to train their models.

03 · Enterprise controls


Banks, defence and public-sector suppliers have their own rules. ONYVEN is built to work within them.

  • Roles and permissions

    Personal accounts and role-based access decide who can see, change and approve.

  • Read-only to start

    Pilots start on a read-only connection to your business systems. Nothing is written to them until you decide it should be.

  • Private deployment

    For regulated industries, ONYVEN can be deployed in your own cloud or on your own infrastructure, depending on your requirements.

  • Security reviews welcome

    We answer your security questionnaire in full and work with your IT and compliance teams before a pilot starts.
