Secure Data Sharing: How to Share Business Data Without Losing Control

Executives signing a controlled data-sharing agreement

Secure data sharing means giving another organization defined, limited access to your data under written terms, with protection before, during and after the exchange. The data should leave your control only as far as the agreement says. In practice that comes down to four things: decide what is shared, share the least you can, put the rules in a contract, and keep checking after the data has moved.

This guide is for operators, executives and general counsel who hold valuable operational records and are asked to share them. It covers what the term means, which controls matter, where the real risks sit, and how the same discipline applies when you license de-identified records to AI developers.

License Data While Retaining Ownership

Mode connects companies with AI developers seeking de-identified operational records, while companies retain ownership of their data.

TL;DR

Secure data sharing is governed access under an agreement, not just an encrypted file transfer. Federal guidance treats it as a lifecycle problem: protect the information before, during and after the exchange.
Put a written agreement in place before any sensitive or confidential data moves. It should name the data, the purpose, the permitted uses and the security requirements.
Share in place, with least-privilege access, rather than sending copies that multiply.
De-identified data can still carry re-identification risk when it is combined with other data, so match the sharing method to the sensitivity.
If you plan to license records to AI developers, keep ownership, share only de-identified copies, and keep everything private until a formal agreement exists.

Most people picture a protected file transfer: encrypt it, send it, done. That covers one moment in time. Secure data sharing covers the whole relationship.

NIST’s guidance on managing the security of information exchanges asks organizations to identify their exchanges, think about how to protect the information before, during and after the exchange, and use agreements to help manage the risk. That is a governance view. The question is not only “is the pipe secure?” but “who can use this, for what, for how long, and what happens when something changes?”

This is also the difference between sharing and copying. When you copy data to a partner, you lose track of where it lives, who touches it and when it is deleted. When you share data, you keep a defined relationship with it: access is granted, scoped, logged and revocable.

The phrases people search for, such as controlled data access, confidential data sharing, secure data exchange or a private data sharing platform, all point at the same idea. Access is controlled, the content stays confidential, and the exchange follows rules both sides have accepted.

The building blocks of a secure exchange

1. An agreement before the data moves

Texas’s Department of Information Resources advises entering a contractual agreement before sharing sensitive, confidential or protected data. It says such an agreement typically describes the data, the purpose, permitted uses, legal authority, privacy-law compliance, security requirements and the transfer method. That list works well for a private company too, even though the source is written for public agencies.

The GSA’s 2023 guidance on information exchanges goes further. It says agreements should specify each organization’s responsibilities, the types and impact level of the information, its permitted use, and how it must be protected during processing, storage and transmission. It bases the agreement on impact level, the relationship between the parties, resiliency requirements and the other party’s access.

2. Least privilege and role-based access

The FCC Cybersecurity Planning Guide recommends that sensitive data access follow least privilege: people get only the access their jobs require, in tiers, under control. It also says role-based access control needs written policies defining roles, privileges, constraints, eligible personnel and how long access may continue before it is reviewed.

For a data-sharing deal, translate that into questions you can answer in writing:

Which roles at the recipient can see the data?
What can each role do: view, query, export, train on it?
When does access expire or get reviewed?
Who at your company approves changes?

The Centers for Medicare & Medicaid Services describes a governed sharing environment in which a remote workspace or API shares data in place, avoiding file export or replication and enabling dynamic authorization. Fewer copies mean fewer places for something to go wrong.

Texas DIR describes a related pattern, a private Closed Data Portal where access is by invitation and the sponsoring organization manages the data, content, users, roles and permissions. The sponsor stays in charge. That is the model to aim for when the data is yours.

Research is moving the same way. A 2024 NIST implementation demonstrated field-level, attribute-based access controls across organizations while preserving each organization’s local protection policies. You do not need that exact architecture, but the principle holds: control access down to the field, not just the file.

3. Sharing in place instead of exporting

4. A baseline of security controls

NIST SP 800-53 Revision 5 defines security controls as administrative, technical and physical safeguards that protect confidentiality, integrity and availability, and privacy controls as the measures that manage privacy risk and applicable privacy requirements. It also recommends a risk-management cycle: categorize systems, select and implement controls, assess them, authorize operation and monitor continuously.

Five stages of the security risk-management cycle

If your teams live in Microsoft 365 or Google Workspace, CISA’s SCuBA project publishes secure-configuration baselines for both, aimed at protecting information organizations create, access, share or store in the cloud. Misconfigured internal sharing is a common starting point for trouble, so fix it before you share outside.

The FTC’s privacy-by-design framework says organizations should embed privacy and security from the outset, collect only the data needed for a specific purpose, dispose of it safely when no longer needed and use reasonable security. Data minimization is the cheapest control you have. Records you never hand over cannot leak.

The risks that matter for business data

The 2025 Federal Zero Trust Data Security Guide lists the principal risks of sharing: unauthorized access or disclosure, privacy-law noncompliance, loss of confidentiality or integrity, excessive replication, third-party control failures, poor resilience, and residency or sovereignty conflicts. The same guide notes that third-party noncompliance with privacy regulations can lead to fines or legal disputes.

For a company that wants to share operational records such as emails, support tickets and CRM history, three of these deserve special attention.

Personal data hiding in business records

Operational records are full of names, addresses, account numbers and free text written by humans who never expected an outside reader. A support ticket can contain a customer’s health detail or a card fragment. Before anything is shared, you need to know what is in it. Which federal and state privacy rules apply depends on your sector and on whose data it is, so general counsel should map the rules for your specific records before any sharing begins.

Re-identification

The same federal guide warns that even data described as de-identified can carry re-identification risk when it is combined with other data. The conclusion is not that de-identification is useless. It is that de-identification is a process you verify, not a label you apply. Ask who performs it, what is removed or transformed, how the result is tested and what the recipient is barred from doing with it, including any attempt to re-link records.

Third parties and downstream control

Once data sits with a recipient, your controls depend on their controls. That is why agreements matter, and why the GSA guidance calls for continuous maintenance of the systems, the exchange and the exchanged information. It says agreements should be reviewed on an agreed schedule, typically annually, and that material changes to either system, the exchange or its configuration should be disclosed and assessed for agreement modification or replacement.

Match the method to the sensitivity

There is no single correct way to share. OECD guidance says no single solution fits data-sharing risks: APIs and isolated data sandboxes can control access over time, while anonymized and aggregated data is generally safer to share openly. The right mechanism depends on sensitivity, re-identification risk, intended reuse and the roles of the participants.

A practical way to apply that:

Data type	Typical approach	Controls to expect
Aggregated or anonymized statistics	Broader sharing is generally safer	Terms of use, no re-linking clause
De-identified operational records	Licensed, scoped, contract-governed	De-identification process, permitted-use limits, review schedule
Sensitive or confidential records	Invitation-only portal or sandbox, share in place	Role-based access, logging, agreement before access
Regulated personal data	Only with legal sign-off	Privacy-law review, strict purpose limits

Inventory the exchange. What data, which systems, which recipient, for what purpose.
Classify it. Is it confidential, personal, regulated, proprietary?
Minimize. Remove fields and records the purpose does not need.
De-identify where the purpose allows, and test the result.
Choose the mechanism. Share in place when you can; export only when you must.
Write the agreement. Data, purpose, permitted uses, security, transfer method, review schedule, deletion.
Set access. Named roles, least privilege, an end date.
Review on a schedule, and whenever systems or the exchange change.

Licensing business records to AI developers

AI developers want real-world business records because they reflect how work actually happens: how customers phrase problems, how support resolves them, how deals progress. Companies in finance, software and consulting often hold years of this material with no revenue attached to it.

The security question here is the same one this article has been asking, applied to a specific deal. Can you earn from your records while keeping ownership, limiting what leaves the building and keeping everything private until the terms are signed?

That is the model Mode is built around. Mode is a marketplace that connects companies holding operational records, such as emails, support tickets, chat, documents, CRM histories and code repositories, with AI developers who want them for training. In Mode’s model, the company keeps ownership of its records and only de-identified copies are shared. Mode also offers guidance and readiness checks, and its approach is designed to keep company data private until a formal agreement is reached. Mode describes potential earnings of $100K to $5M, depending on the quality and volume of the data shared. Treat that as the program’s own stated range, not a promise for any one company.

Everything above still applies to such a deal. Before you sign anything, check that the agreement covers permitted use, security requirements, re-identification limits and a review schedule. You can read the Mode terms source guide and the Mode questions and answers to see how the process is described.

Our perspective

Most companies come to us asking the wrong first question. They ask what their data is worth. The better first question is what they can share without ever losing control of it.

Our view is simple. Operational records are an asset you already own, and ownership should not change when you license them. That is why we believe the right structure keeps the original records with you and shares only de-identified copies, under a formal agreement, with nothing exposed before that agreement exists.

Readiness is where deals are won or lost. A company that has classified its data, knows where the personal information sits and has counsel comfortable with the terms moves faster and negotiates better. A readiness check is designed to surface those answers privately, before anyone outside your company sees a single record.

We built the program for owners, COOs and general counsel who want a new revenue stream without a data-loss story attached to it. Secure sharing is not the obstacle to monetization. Done properly, it is what makes monetization possible.

Teams that want to review this together can use the fit check for teams, or book a 20-minute call to talk through your situation.

FAQ

No. Encryption protects data in transit or at rest, but it says nothing about who may use the data, for what, or for how long. Federal guidance frames secure exchange as protecting information before, during and after the exchange, with agreements that manage the risk.

For sensitive, confidential or protected data, yes. Texas DIR advises a contractual agreement first, and such agreements typically describe the data, purpose, permitted uses, privacy-law compliance, security requirements and transfer method. Have counsel review it.

Not automatically. Federal guidance notes that de-identified data can still carry re-identification risk when combined with other data. Verify how de-identification was done, test the result and bar the recipient from re-linking records.

Can I license my company’s records and still own them?

That is the structure Mode is designed around: the company keeps its original records, and only de-identified copies are shared under a formal agreement. Check the specific terms of any deal, including permitted use and review rights, with your counsel.
