Federal agencies increasingly operate in shared service models, joint operations environments, and centralized IT and security operations centers where endpoint telemetry from one organization is directly relevant to another. A shared SOC supporting multiple components needs performance and behavioral data from every managed endpoint. A mission partner network requires visibility into endpoint health across organizational boundaries to troubleshoot degraded services. A cross-agency threat hunting team needs consistent telemetry to identify lateral movement that does not respect agency lines. The operational case for sharing endpoint telemetry is real, and it is growing.
What most programs underestimate is the governance infrastructure required before that sharing can happen. Endpoint telemetry collected through a Digital Employee Experience (DEX) program carries attributes that complicate interagency exchange: it may contain personally identifiable information tied to named users, it may reflect system configurations that are sensitive under agency security policies, and it may be subject to records management obligations that vary by agency. Sharing it without a formal agreement creates legal exposure, compliance risk, and accountability gaps that can surface during audits, incidents, or inspector general reviews.
A federal DEX data sharing agreement is the mechanism that resolves those tensions. It establishes the authority to share, defines what data moves and under what conditions, assigns stewardship responsibilities, and creates the operational guardrails that allow telemetry exchange to function without becoming a liability. Most agencies have experience with data sharing agreements in the context of records, benefits data, or law enforcement information. Applying that framework to endpoint telemetry requires adapting familiar structures to a technical domain that moves faster and generates far more granular data than traditional interagency exchanges.
This article is a practical playbook for federal CIO, CISO, privacy, records, and enterprise operations stakeholders who need to design, negotiate, and operationalize a DEX telemetry sharing agreement. It covers what belongs in the agreement, who needs to approve it, how to handle classification and sensitivity, and how to keep the agreement functional as programs evolve.
Key Takeaways
- A DEX data sharing agreement must establish legal authority before any telemetry exchange begins, not after the technical integration is already operational.
- Data minimization is not optional. Agreements should define specific telemetry elements permitted for exchange, not grant blanket access to all collected endpoint data.
- Permitted use cases must be enumerated and enforced. Threat hunting, performance troubleshooting, and shared service operations each carry different access and handling requirements.
- Privacy and records management obligations do not disappear when data crosses an agency boundary. The receiving agency inherits handling responsibilities that must be explicitly addressed in the agreement.
- Contractor access to shared telemetry requires its own authorization layer within the agreement, including flow-down clauses and access controls tied to specific roles.
- Agreements without change control and termination provisions become liabilities when programs evolve, personnel change, or the original operational need no longer applies.

Why Formal Agreements Matter for DEX Telemetry Exchange
Endpoint telemetry generated by a DEX program is not a neutral dataset. It includes application response times tied to specific user sessions, login events, device health metrics linked to named workstations, network latency measurements associated with specific locations, and crash or error logs that may contain fragments of user activity. Individually, these data points look like operational metrics. In aggregate, they create a detailed behavioral and technical profile of how specific users interact with specific systems at specific times.
That profile has legitimate operational value across agency boundaries. A shared IT operations center managing endpoints for multiple components needs it to troubleshoot service degradation. A joint security operations center needs it to correlate endpoint behavior with network-level threat indicators. A centralized workforce analytics function needs it to identify systemic performance problems that affect mission delivery across a department. None of those use cases are unreasonable. All of them require a formal agreement before the data moves.
Without a formal agreement, the sharing arrangement has no defined authority, no accountability structure, and no mechanism for resolving disputes about how data is used. When an incident occurs, or when an auditor asks who authorized the exchange, the answer cannot be “we assumed it was fine because we’re all in the same department.” Federal privacy law, records management requirements, and agency-specific system security plans all treat data sharing as a deliberate act that requires documented authorization. The agreement is that documentation.
There is also a practical operational reason to formalize the agreement early. Technical integrations for telemetry sharing tend to get built quickly and then persist for years without review. If the agreement is not in place before the pipeline is operational, the program will eventually face pressure to retroactively justify an arrangement that has already been running. That is a harder problem than designing the agreement correctly from the start.
Core Structure of a DEX Data Sharing Agreement
A DEX data sharing agreement borrows from the structure of a traditional memorandum of understanding or data use agreement, but it needs to address technical specifics that those templates rarely anticipate. The following framework reflects the elements that federal programs consistently need to address when formalizing endpoint telemetry exchange.
Agreement Elements Checklist
- Purpose and Authority. State the operational purpose of the exchange, identify the legal or regulatory authority under which sharing is permitted, and name the authorizing officials at each participating organization. Include references to applicable statutes, OMB policies, or agency directives.
- Data Elements and Minimization. Enumerate the specific telemetry fields permitted for exchange. Do not grant access to all collected data. Define what is included, what is excluded, and the rationale for each decision. Address whether user-identifying fields are transmitted or pseudonymized before transfer.
- Classification and Handling. Specify the sensitivity level of the shared data, the handling requirements that apply, and any restrictions on storage, transmission, or processing at the receiving organization. Address whether the data may be combined with other datasets in ways that would elevate its sensitivity.
- Roles and Stewardship. Identify the data owner, data steward, and system owner at each organization. Assign responsibility for data quality, access provisioning, and compliance monitoring. Define who has authority to approve changes to the sharing arrangement.
- Access Controls. Define who at the receiving organization may access the shared telemetry, under what role-based conditions, and through what technical mechanisms. Address privileged access separately from general operational access.
- Permitted and Prohibited Uses. Enumerate the specific operational purposes for which the data may be used. Explicitly prohibit uses that are outside scope, including secondary analysis, personnel actions, or sharing with additional parties not named in the agreement.
- Retention and Deletion. Specify how long the receiving organization may retain the shared data, what triggers deletion, and how deletion is confirmed. Align retention periods with the originating agency’s records schedule.
- Incident Response. Define the notification obligations if shared data is involved in a security incident, breach, or unauthorized disclosure. Specify response timelines, escalation paths, and coordination responsibilities between organizations.
- Auditability. Require that access to shared telemetry be logged, that logs be retained for a defined period, and that each organization make its access logs available to the other upon request or during a review.
- Sharing with Contractors. Address whether the receiving organization may provide access to contractors, under what conditions, and what flow-down requirements apply. Require that contractor access be documented and subject to the same use restrictions as government personnel.
- Change Control. Define the process for modifying the agreement when data elements, use cases, participating organizations, or technical mechanisms change. Require that material changes be approved by the same authorities who approved the original agreement.
- Termination. Define the conditions under which either party may terminate the agreement, the notice period required, and the data disposition obligations that apply upon termination.
The level of detail required in each section will vary based on the sensitivity of the data, the nature of the operational relationship, and the specific use cases being authorized. A shared service arrangement within a single department will look different from an agreement between two independent agencies. The structure above applies to both, but the depth of each section scales with the complexity and risk of the exchange.
Approval Authority Considerations
Approval authority for a DEX data sharing agreement typically sits with the agency CIO or CISO, the Senior Agency Official for Privacy, and the records management officer when the exchange implicates federal records. In some environments, the authorizing official for the system of record that collects the telemetry must also concur. Programs that skip privacy and records review because the data looks purely technical tend to discover the oversight during an assessment or audit, not before.
Defining Permitted Use Cases and Prohibited Uses
The permitted use section of a DEX data sharing agreement is where most programs are either too vague or too narrow. Vague language like “operational support purposes” creates ambiguity that different stakeholders will interpret differently. Overly narrow language that names only one specific use case creates friction every time the operational need expands slightly, requiring agreement amendments for routine operational activities.
The practical approach is to enumerate use cases at the category level with enough specificity to distinguish them from prohibited uses. The three categories that appear most frequently in federal DEX telemetry sharing arrangements are shared service operations, threat hunting, and performance troubleshooting. Each carries different access and handling implications.
| Use Case | Typical Data Needed | User-Identifying Fields | Access Tier | Retention Sensitivity |
|---|---|---|---|---|
| Shared service operations | Device health, patch status, application availability, connectivity metrics | Optional, pseudonymization recommended | Operations team, role-based | Moderate |
| Threat hunting | Process execution, login events, network connections, behavioral anomalies | Required for correlation, strict handling | Security analysts, privileged access | High |
| Performance troubleshooting | Application response times, session latency, error rates, resource utilization | Typically not required, aggregate preferred | Operations and engineering, role-based | Low to moderate |
| Workforce analytics | Aggregate productivity indicators, application adoption rates | Not permitted in most sharing contexts | Restricted, requires separate authorization | High, privacy implications |
Prohibited uses deserve as much attention as permitted uses. The agreement should explicitly prohibit using shared telemetry to support personnel actions, disciplinary proceedings, or workforce monitoring activities not covered by the originating agency’s system of records notice. It should prohibit sharing the data with parties not named in the agreement, including subcontractors who are not specifically authorized. It should prohibit combining the shared telemetry with other datasets in ways that would create a new system of records without separate authorization.
Practitioner Reality
Threat hunting use cases create the most friction in DEX telemetry sharing agreements because they require user-identifying fields that other use cases can avoid. Security teams need those fields to correlate endpoint behavior with identity-based threat indicators. Privacy officers need to ensure that the same fields are not retained longer than necessary or used outside the security context. The agreement needs to address this tension directly, not leave it to be resolved operationally after the data is already flowing. Programs that defer this conversation tend to find that either the security team is working with incomplete data or the privacy officer is unaware of what is actually being shared.
Privacy, Records Management, and Classification Handling
Privacy considerations in a DEX telemetry sharing agreement center on three questions: Does the shared data constitute a system of records under the Privacy Act? Does it require coverage under a system of records notice? And does the receiving agency’s use of the data fall within the routine uses published by the originating agency? If the answer to any of those questions is uncertain, the privacy review needs to happen before the agreement is signed, not after.
Endpoint telemetry that includes user-identifying information and is retrieved by name or personal identifier meets the threshold for a system of records. Many agencies have published system of records notices for their endpoint management or monitoring systems that include routine use provisions for sharing with other federal agencies for security or operational purposes. Those provisions need to be verified against the specific use cases in the agreement. A routine use that covers sharing for security purposes may not cover sharing for general IT operations troubleshooting.
Records management obligations follow the data, not the organization. When telemetry is shared with a receiving agency, that agency becomes responsible for managing the records in accordance with the originating agency’s records schedule, or for establishing its own schedule if the data is transformed or combined in ways that create a new record type. The agreement should specify which schedule applies, who is responsible for compliance, and how disposition is coordinated when the retention period expires.
Classification and sensitivity handling is straightforward when the telemetry is unclassified, but it requires explicit treatment in the agreement. Even unclassified endpoint telemetry can be sensitive under controlled unclassified information frameworks, particularly when it reflects system configurations, network topology, or user activity on systems that support sensitive missions. The agreement should specify the CUI category if applicable, the handling requirements that flow from that designation, and whether the data may be processed on systems that do not meet those handling requirements.
For programs operating in classified environments, the agreement needs to address whether telemetry from classified endpoints may be included in the exchange, what classification markings apply, and whether the receiving organization has the appropriate facility clearance and system accreditation to receive and process that data. Mixing classified and unclassified telemetry in a shared pipeline without explicit authorization is a compliance problem that tends to surface during RMF assessments.
Common Mistakes
The most consistent mistake in federal DEX telemetry sharing is treating the technical integration as the hard part and the agreement as administrative paperwork. Programs that build the pipeline first and negotiate the agreement later create operational risk that is difficult to unwind. Once telemetry is flowing and operational teams are depending on it, there is pressure to keep it running even if the governance review surfaces problems that would have changed the design.
Granting blanket access to all collected telemetry rather than defining specific data elements is a data minimization failure that creates both privacy risk and unnecessary security exposure. The receiving organization does not need every field the originating agency collects. Defining the minimum necessary dataset forces a useful conversation about what the operational use case actually requires, and it reduces the scope of the agreement’s privacy and records obligations.
Failing to address contractor access is a gap that appears in a significant share of interagency data sharing arrangements. Government personnel at the receiving organization are not the only ones who will touch the shared telemetry. Contractors supporting the shared SOC, the IT operations center, or the performance engineering team will have access as part of their normal duties. If the agreement does not address contractor access, those individuals are operating outside the authorization framework, which creates audit findings and potential legal exposure.
Agreements that lack change control provisions become stale quickly. DEX programs evolve. New telemetry sources are added. Use cases expand. Personnel change and institutional knowledge about what the agreement covers and why specific decisions were made disappears. Without a documented change control process, programs either operate under an agreement that no longer reflects reality or they avoid making necessary changes because the amendment process is unclear.
Treating compliance with the agreement as equivalent to operational effectiveness is another failure mode. An agreement that is technically compliant but does not reflect how the data is actually being used creates a false sense of security. Programs should validate that the operational workflows match the agreement’s permitted use provisions, not just confirm that the agreement exists.
Finally, programs frequently underestimate the time required to get agreements approved. Privacy review, records management coordination, legal review, and CIO or CISO concurrence each take time, and they often run sequentially rather than in parallel. Starting the agreement process after the technical integration is already designed means the program will either delay the operational capability or accept the risk of operating without authorization while approvals are pending.
Recommended Federal Approach
The approach below reflects how programs that have successfully established DEX telemetry sharing agreements have sequenced the work. It is not a universal checklist. The specific steps and their order will vary based on the organizations involved, the sensitivity of the data, and the operational urgency of the use case.
Start with the operational use case, not the data inventory. Before drafting any agreement language, document what the receiving organization needs to accomplish and why existing data sources are insufficient. This scoping exercise defines the minimum necessary dataset and prevents the agreement from expanding to cover data that is not actually needed. It also gives privacy and legal reviewers a concrete operational context to evaluate rather than an abstract data sharing request.
Identify the authority chain early. Determine which officials at each organization must approve the agreement, whether a system of records notice needs to be updated or published, and whether the existing RMF authorization for the originating system covers the proposed sharing arrangement. These determinations affect the timeline and may require actions that take months to complete. Identifying them early prevents surprises late in the process.
Conduct a privacy threshold analysis before drafting. The Senior Agency Official for Privacy at the originating agency should assess whether the proposed exchange requires a privacy impact assessment update, a system of records notice amendment, or a new routine use publication. This analysis should happen before the agreement is drafted, not as a concurrent review.
Draft the data elements annex with technical and legal input together. The list of specific telemetry fields permitted for exchange should be developed jointly by the technical team that understands what the data contains and the legal and privacy team that understands the handling implications. Fields that look like operational metrics often contain user-identifying information that changes the handling requirements. This review is most effective when both perspectives are present simultaneously.
Build the access control model before finalizing the agreement. The agreement’s access control provisions should reflect a real access model, not a theoretical one. Identify the specific roles at the receiving organization that will access the shared telemetry, the technical mechanisms that will enforce access restrictions, and the process for provisioning and deprovisioning access. If the technical implementation cannot support the access model described in the agreement, either the implementation needs to change or the agreement needs to reflect what can actually be enforced.
Run a parallel review with records management. Records management review can proceed in parallel with privacy and legal review once the data elements annex is drafted. The records officer needs to determine whether the shared data is covered by an existing schedule, whether the receiving agency needs to establish its own schedule, and how disposition will be coordinated. This review is frequently deferred and then becomes a compliance finding.
Pilot the operational workflow before declaring the agreement fully operational. Once the agreement is approved and the technical integration is in place, validate that the operational workflows at the receiving organization match the permitted use provisions. Confirm that access logs are being generated and retained, that the data minimization controls are functioning as designed, and that the incident notification process is understood by the personnel who would need to execute it. For implementation guidance on the underlying endpoint telemetry collection and health monitoring that feeds these agreements, the article on using DEX telemetry to improve federal endpoint health covers the technical foundation in detail.
Establish a review cycle. Schedule an annual review of the agreement to confirm that the data elements, use cases, access controls, and retention provisions still reflect operational reality. Assign a named individual at each organization who is responsible for initiating the review and coordinating any amendments. Without a named owner and a scheduled review, agreements persist unchanged long after the operational context that justified them has changed.
