TL;DR: IAST and RASP can improve visibility into service account and API behaviour, but Entro Security argues they still leave gaps in lifecycle control, contextual permissions analysis, and compliance evidence for non-human identities. The real issue is that testing-time and runtime controls do not replace end-to-end NHI governance across creation, monitoring, rotation, and deprovisioning.
NHIMG editorial — based on content published by Entro Security: IAST vs RASP and their blindspots in Non Human Identity Management
By the numbers:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.
- Only 5.7% of organisations have full visibility into their service accounts.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
Questions worth separating out
Q: How should security teams govern non-human identities beyond runtime monitoring?
A: Security teams should govern NHIs across the full lifecycle, not just at test time or in production.
Q: Why do IAST and RASP leave blindspots in NHI management?
A: IAST sees too early and RASP sees too late to manage identity state on its own.
Q: What do teams get wrong about runtime NHI controls?
A: Teams often mistake runtime visibility for complete control.
Practitioner guidance
- Map every NHI to a lifecycle owner Assign responsibility for creation, rotation, review, and offboarding to a named team or control owner so no service account or API key sits outside governance.
- Separate detection from entitlement governance Use IAST for test-phase findings and RASP for runtime response, but back both with periodic entitlement review against actual usage patterns.
- Enforce just-in-time access for task-scoped identities Replace persistent access where possible with just-in-time provisioning and automatic deprovisioning after the workflow completes.

Entro Security's full blog covers the operational detail this post intentionally leaves for the source:
- How the vendor distinguishes IAST from RASP at the runtime instrumentation level for NHI monitoring
- Examples of the specific misconfigurations and behaviour patterns the article says each tool can catch in service accounts and APIs
- The article's practical discussion of lifecycle automation, including secrets rotation, vault compatibility, and adaptive response handling
- The vendor's compliance framing for GDPR, HIPAA, and SOC 2 evidence collection

IAST and RASP expose control points, but they do not solve identity governance. The article is right to separate test-time visibility from runtime defense, yet both controls still stop short of lifecycle ownership. NHIs need discovery, entitlement review, rotation, offboarding, and auditability, not just better observation. Practitioners should treat these tools as inputs to governance, not as the governance model itself.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why runtime-only monitoring rarely gives teams a complete governance picture.
A question worth separating out:
Q: How do I know if NHI governance is actually working?
A: Look for evidence that identities are inventoried, owned, reviewed, rotated, and revoked on a repeatable schedule. Effective governance shows up in fewer unmanaged service accounts, better secret hygiene, and audit trails that connect issuance to retirement. If those signals are missing, the programme is still relying too heavily on observation instead of control.
