Private Cases are case records that are visible only to selected users rather than to everyone in a shared workspace. They support granular access control for sensitive investigations, helping teams protect confidential data while maintaining collaboration. In practice, they extend privacy boundaries beyond the case record to related activity and content.
Expanded Definition
Private Cases are a case-level access pattern, not a new identity type. They are used when a sensitive investigation, incident, or compliance matter must be visible only to a defined subset of users, with access decisions applied to the record, its comments, attachments, and related activity. In NHI and agentic operations, that distinction matters because the case often contains secrets, service account details, token traces, and remediation notes that should not be exposed across a broad workspace.
Definitions vary across vendors and platforms, but the operational intent is consistent: limit visibility without breaking collaboration. That usually means combining case privacy with RBAC, audit logging, and workflow controls so authorised responders can act while everyone else remains excluded. This aligns with the broader governance principles reflected in the NIST Cybersecurity Framework 2.0, especially around controlled access and monitored handling of sensitive information. Private Cases should be treated as a containment mechanism for casework, not as a substitute for proper entitlement design or secret handling.
The most common misapplication is assuming a private case automatically protects all attached data, which occurs when related files, comments, or linked systems still inherit broader workspace permissions.
Examples and Use Cases
Implementing Private Cases rigorously often introduces workflow friction, requiring organisations to weigh tighter confidentiality against slower cross-team visibility and review.
- A security operations team opens a private case for a suspected service account compromise so only incident responders, IAM administrators, and legal reviewers can see token details and containment actions.
- A compliance team uses a private case to track findings involving API keys stored in code, keeping remediation notes restricted while still coordinating with application owners.
- An investigation into secrets sprawl references the findings in Ultimate Guide to NHIs to justify a narrower audience for the case and its evidence.
- A third-party access review keeps supplier-related identity issues private until exposure risk, contract impact, and revocation steps are validated.
- A platform team links a private case to a service account offboarding task so only the approvers can view the revocation timeline and exception rationale.
In practice, private case handling works best when it is paired with least privilege and explicit approval paths, not informal trust. That is especially important in environments where identity governance is already strained, since NHI Mgmt Group reports that 79% of organisations have experienced secrets leaks, with 77% resulting in tangible damage. For standards-driven access design, practitioners often map these workflows to the same control discipline described in NIST Cybersecurity Framework 2.0.
Why It Matters in NHI Security
Private Cases matter because NHI incidents are rarely confined to a single object. A case may contain indicators of compromise, credential rotation plans, offboarding steps, and evidence that points to other exposed identities. If that case is too widely visible, the organisation expands the blast radius of the incident and increases the chance that sensitive details will be copied, forwarded, or misused before containment is complete.
This is especially relevant in environments where service accounts, API keys, and automation credentials are already difficult to track. Ultimate Guide to NHIs notes that only 5.7% of organisations have full visibility into their service accounts, which means case records often become the temporary source of truth during investigation and remediation. That makes privacy controls part of operational resilience, not just administrative convenience. Governance teams should also align private case permissions with NIST Cybersecurity Framework 2.0 practices for access control, auditability, and recovery coordination.
Organisations typically encounter the limits of private-case design only after a sensitive investigation is over-shared, at which point case privacy becomes operationally unavoidable to fix.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and OWASP Agentic AI Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST Zero Trust (SP 800-207) and NIST SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Private Cases constrain who can view NHI-related incident and remediation data. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions management underpins selective visibility for sensitive cases. |
| NIST Zero Trust (SP 800-207) | AC-4 | Zero Trust requires explicit, enforced access checks for sensitive case content. |
| NIST SP 800-63 | IAL2 | Identity assurance supports confident assignment of restricted case access. |
| OWASP Agentic AI Top 10 | A2 | Agentic systems must not overexpose sensitive case context to tools or agents. |
Restrict case visibility and related artifacts to the minimum set of authorised responders.
