Custom context is organisation-specific information supplied to an AI system so its output reflects local naming, ownership, and business meaning. For identity workflows, it reduces generic or ambiguous outputs and makes generated metadata more useful for certification and audit.
Expanded Definition
Custom context is the organisation-specific metadata, naming, ownership, and business meaning supplied to an AI system so its generated output matches local identity and governance conventions. In NHI workflows, it helps the model distinguish a production service account from a test token, or a regional API key from a shared platform credential.
This term is adjacent to prompt engineering, but the emphasis is different: prompt engineering shapes a response, while custom context supplies authoritative facts the system should use when generating labels, summaries, or remediation notes. Definitions vary across vendors because some platforms treat custom context as retrieval input, some as prompt augmentation, and others as policy-bound reference data. For NHI management, the practical standard is simple: the context must be current, scoped, and traceable back to approved sources, especially when it influences certification evidence or audit text. The NIST Cybersecurity Framework 2.0 is relevant here because it reinforces the need for governed, reliable information supporting security outcomes.
The most common misapplication is treating custom context as free-form enrichment, which occurs when teams allow model inputs to include stale ownership data, undocumented abbreviations, or unapproved business labels.
Examples and Use Cases
Implementing custom context rigorously often introduces governance overhead, requiring organisations to weigh better output precision against the cost of maintaining trusted source data.
- An identity platform generates certification notes that map each service account to its real application owner, environment, and renewal cycle rather than producing generic text.
- A SOC workflow enriches API key alerts with application tier, data classification, and escalation path so analysts can triage faster and with less ambiguity.
- An automation agent uses approved naming conventions to describe a vault entry, improving searchability and reducing duplicate records during review.
- A remediation assistant references the Ultimate Guide to NHIs to stay aligned with NHI governance concepts such as lifecycle control, rotation, and offboarding.
- A compliance team feeds business-unit ownership data into the model so generated evidence statements match the organisation’s actual control environment and do not invent roles or approvals.
These use cases are most effective when the context is limited to authoritative sources, versioned, and reviewed like any other security control input. Where teams instead paste in ad hoc notes from tickets or chat logs, the model may amplify inconsistency rather than reduce it.
Why It Matters in NHI Security
Custom context matters because NHI security problems are often made worse by bad labels, missing ownership, and ambiguous remediation language. If an AI system cannot distinguish which secret belongs to which workload, it can generate misleading inventory records, weak certification evidence, or incorrect offboarding instructions. That creates operational drag in environments where NHIs already outnumber human identities by 25x to 50x, and visibility is frequently poor. NHIMG reports that only 5.7% of organisations have full visibility into their service accounts, which makes trustworthy context a practical control issue, not a documentation preference. The Ultimate Guide to NHIs also shows that 97% of NHIs carry excessive privileges, so context that correctly identifies ownership and intent helps prevent broad access from being normalised in generated output.
Custom context also supports Zero Trust-style decision making by keeping the model grounded in the asset, environment, and purpose of the identity being discussed. Organisations typically encounter the consequences only after an audit finding, incident review, or failed secret rotation, at which point custom context 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 Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Context quality affects how NHIs are identified, classified, and governed in generated outputs. |
| NIST CSF 2.0 | GV.OV-01 | Governed, reliable information is required to support security oversight and decision-making. |
| NIST Zero Trust (SP 800-207) | JIT | Zero Trust decisions depend on current asset and identity context, not assumptions. |
