Data that shows whether a user or group is actively using a subscription often enough to justify keeping it. It can include login frequency, feature adoption, or recent activity. In governance workflows, usage evidence helps distinguish legitimate need from legacy entitlement drift.
Expanded Definition
Usage evidence is governance data that demonstrates whether an account, team, or business unit is actively benefiting from a subscription, entitlement, or access path. In NHI and IAM operations, it is less about proving identity and more about proving continued need. That distinction matters because stale access often persists after a project ends, a team changes, or automation is replaced. Usage evidence can include login frequency, API call activity, feature adoption, job execution history, or recent access logs, but definitions vary across vendors and internal governance programs. No single standard governs this yet, so organisations should document what counts as sufficient evidence before they automate renewal or revocation decisions. For broader control mapping, the NIST Cybersecurity Framework 2.0 is useful for connecting usage data to access governance and monitoring outcomes. NHIMG has repeatedly shown that weak entitlement visibility is common, including in cases like the JetBrains GitHub plugin token exposure, where access persistence and poor lifecycle control can outlast the original need. The most common misapplication is treating any historical login as ongoing business justification, which occurs when governance teams ignore whether the underlying workload or subscription is still in active service.
Examples and Use Cases
Implementing usage evidence rigorously often introduces review overhead and logging dependence, requiring organisations to weigh access reduction against the cost of collecting trustworthy activity signals.
- A platform team reviews monthly API call volume before renewing a service account, because idle tokens are often a sign of forgotten automation rather than active workload use.
- A procurement workflow requires feature adoption metrics before renewing SaaS seats, so dormant subscriptions do not become permanent entitlement drift.
- An identity governance team checks recent build-job execution data before preserving CI/CD credentials, using actual runtime activity as the justification signal.
- A security analyst compares vault retrieval logs against approved ownership records to determine whether a secret is still needed by the current application owner.
- A cloud operations group uses access logs and pipeline telemetry together to confirm that a group-managed identity still supports production tasks.
These patterns are especially important when usage evidence is used to justify continuation rather than initial issuance. That is why it should be paired with a defined review cadence and a revocation path when evidence goes stale. NHIMG’s guidance on lifecycle discipline aligns with the broader lessons in the Ultimate Guide to Non-Human Identities, which frames visibility and offboarding as core governance functions. In practice, usage evidence is strongest when it comes from multiple sources, not a single dashboard, because one log stream can be misleading while the broader access pattern is clearly inactive.
Why It Matters in NHI Security
Usage evidence matters because NHI environments accumulate dormant access quickly, and dormant access becomes attack surface. In NHIMG’s research, 97% of NHIs carry excessive privileges, and 71% are not rotated within recommended time frames, which means stale entitlements often remain both usable and powerful. When organisations lack usage evidence, they cannot tell whether a token, service account, or subscription is still supporting a live workload or simply persisting from a prior state. That uncertainty leads to over-retention, weak offboarding, and avoidable exposure. It also weakens incident response, because teams cannot quickly distinguish a legitimate integration from an abandoned one during containment. The governance problem is not only security; it is also operational waste, especially when unused access continues to be funded and monitored as if it were active. For a practical view of how access sprawl becomes a control issue, the Ultimate Guide to Non-Human Identities is the clearest NHIMG reference point, and it connects directly to broader control objectives in the NIST Cybersecurity Framework 2.0. Organisations typically encounter usage evidence failures only after a breach, a failed audit, or a costly renewal dispute, at which point the concept becomes operationally unavoidable to address.
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 address the attack and risk surface, while NIST CSF 2.0 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Usage evidence supports lifecycle control by proving whether access is still needed. |
| NIST CSF 2.0 | PR.AA-01 | Access governance requires evidence that entitlements remain appropriate and active. |
| NIST CSF 2.0 | DE.CM-01 | Monitoring captures the activity records needed to assess actual use over time. |
Review usage signals regularly to validate ongoing access and remove stale entitlements.
