The process of adding externally sourced identity or entitlement data to a token during issuance. It lets downstream systems make finer-grained decisions without calling back to another service, but it only works if the added claims are trustworthy and operationally maintained.
Expanded Definition
Claim enrichment is the practice of attaching external identity, device, entitlement, or risk data to a token at issuance so downstream services can authorise requests without repeated lookups. In NHI and IAM architectures, the goal is faster decisions and less runtime dependency, but the tradeoff is that every claim becomes a security decision artifact.
Definitions vary across vendors because some products treat enrichment as a token minting step, while others extend it to policy evaluation, attribute sourcing, or session shaping. The operational boundary matters: a claim that reflects a role, tenant, trust score, or workload posture should be current, attributable, and bounded by the issuer’s authority. Guidance in the NIST Cybersecurity Framework 2.0 reinforces that identity data used for access decisions must be governed as part of access control and information integrity, not treated as decorative metadata.
The most common misapplication is enriching tokens with stale or overbroad attributes, which occurs when issuers cache entitlement data longer than its validity window or pull from an untrusted source of record.
Examples and Use Cases
Implementing claim enrichment rigorously often introduces tighter coupling between identity governance and token issuance, requiring organisations to weigh faster downstream authorisation against the cost of maintaining trusted source systems.
- A service token includes tenant ID, environment, and approved API scope so a gateway can enforce access without calling an entitlement service on every request.
- An AI agent token is enriched with workload classification and tool permissions so the runtime can limit which connectors the agent may invoke.
- A CI/CD workload receives build provenance and repository trust claims, allowing deployment controls to distinguish approved automation from ad hoc scripts.
- An internal admin session is issued with risk-based claims derived from device posture and location, enabling policy to step up or deny access when conditions change.
- After a public secret exposure, teams often revisit whether tokens carried too much static entitlement data, a pattern highlighted in the DeepSeek breach analysis and in broader platform guidance from NIST Cybersecurity Framework 2.0.
NHIMG research on the State of Secrets in AppSec shows that 43% of security professionals worry AI systems will learn and reproduce sensitive patterns, which makes careful claim selection especially important when enrichment draws from high-risk data stores.
Why It Matters in NHI Security
Claim enrichment can reduce latency and centralise policy inputs, but it also expands the blast radius of bad identity data. If an attacker can influence the upstream attribute source, they may inherit privileges through otherwise valid tokens. If the enrichment process is too generous, service accounts and AI agents may receive claims they never needed, weakening least privilege and making abuse harder to detect.
This is especially important for Non-Human Identities because machine credentials are often short-lived, highly automated, and consumed at scale. NHIMG research in The State of Secrets in AppSec reports that organisations spend an average of 32.4% of security budgets on secrets management and code security, yet the average time to remediate a leaked secret is still 27 days. That gap matters when enriched claims are derived from secret-backed systems, entitlement directories, or fragile pipeline metadata.
Practitioners also need to treat claim content as governed data, because downstream policy engines may assume it is authoritative even when the upstream source is stale, duplicated, or compromised. Organisations typically encounter the operational cost of claim enrichment only after a privilege escalation, token misuse, or access denial incident, at which point the enrichment path 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 | Claim quality and token trust are core to NHI identity and authorization integrity. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions should be managed and enforced through trusted identity attributes. |
| NIST Zero Trust (SP 800-207) | 3.1 | Zero Trust relies on continuous, contextual identity signals for authorization decisions. |
Limit enriched claims to verified sources and review token content for least-privilege necessity.
