Use AI on diligence packs, investment memos, policies, and client correspondence without giving a public model operator readable access to the underlying data.
Finance
Most finance teams do not lack AI use cases. They lack a way to prove confidentiality, sovereignty, and operational control to risk, compliance, and clients.
“We don’t use AI at all due to confidentiality concerns.”

DORA requires demonstrable third-party risk management. Tresor’s cryptographic receipts are auditable evidence, not policy statements, that data was processed inside attested hardware.
Mandates, portfolio data, term sheets, and internal notes can stay in a sealed environment instead of leaking into unmanaged AI usage.
Security and compliance teams can review how work was processed without asking front-office users to stop using the tools they need.
Analysts, compliance, leadership, and client teams can work from the same protected context instead of emailing extracts back and forth.
Risk analysis, due diligence summaries, regulatory drafting, and internal memos move faster when the supporting data stays inside sealed execution rather than a public AI operator.
Turn long packs, filings, and memos into reviewable briefs without copying the underlying data into a public tool.
Retrieve relevant clauses, exposures, and historical context across internal repositories in one place.
Prepare investment notes, board updates, and client-facing explanations from the same controlled workspace.
The control surface has to satisfy analysts, compliance, and procurement at the same time, without forcing the business back to manual work.
Client records, internal analysis, and regulatory material stays readable only in the browser and inside attested compute, not in an operator-accessible app tier.
Routing, storage, and execution stay aligned with European sovereignty and procurement expectations instead of backhauling work into a general public AI stack.
Each response can be tied back to cryptographic receipts and published verification material, so security and compliance teams can check the claim themselves.
Start with one review-heavy workflow, keep the documents in a shared project, and expand only after the operating model is verifiable end to end.
Due diligence, policy review, internal research, and portfolio reporting are typical starting points.
Keep approval in the same workspace so usage does not escape into unmanaged side channels.
Once the controls are accepted, the same setup can support adjacent teams without changing the underlying confidentiality posture.
Executive Summary
Tresor is built on a simple promise: your conversations belong to you, not us. Every message you type is protected by end-to-end encryption and processed only inside secure computing environments that even Tresor cannot inspect. Teams can now collaborate inside shared workspaces without ever handing Tresor access to their plaintext. This whitepaper explains the principles and safeguards behind Tresor’s zero-access design, showing how we deliver practical confidentiality without trade-offs in usability.
