TL;DR: IAM completeness and accuracy in financial institutions keeps failing because remediation work, owner follow-up, and evidence assembly do not happen at scale, leaving orphaned accounts, missing ownership, and NHIs without expiration dates, according to Twine Security. The governance problem is operational, not theoretical: unless the work is continuously executed, the same audit gaps reappear each quarter.
NHIMG editorial — based on content published by Twine Security: Why IAM Completeness and Accuracy Keeps Failing at Financial Institutions
Questions worth separating out
Q: How should security teams handle incomplete access review populations in financial institutions?
A: They should reconcile identity sources before the certification window opens, then validate that every account, entitlement, and NHI is in scope.
Q: Why do NHIs complicate IAM completeness and accuracy programs?
A: NHIs complicate these programs because they often lack clear ownership, regular lifecycle events, and reliable expiry dates.
Q: What breaks when access review remediation is left to manual follow-up?
A: Manual follow-up creates delays, missed responses, and inconsistent evidence collection, which means the same defects survive into the next cycle.
Practitioner guidance
- Map review population completeness before each certification cycle Reconcile HR, IGA, PAM, and application inventories before the review window opens so missing accounts, disconnected systems, and stale NHI records are caught early.
- Automate owner follow-up and escalation paths Standardise outreach, reminders, and escalation rules so analysts are not manually chasing responses across every certification cycle.
- Enforce expiration and ownership for all NHIs Require a named owner, a business purpose, and an expiration condition for every service account, token, and certificate.
The control model has to absorb owner follow-up, evidence collection, and lifecycle correction as ongoing work, not as audit-season recovery?

Operational execution, not tooling volume, is the real failure point. Financial institutions often have enough visibility to know what is wrong, but not enough operational capacity to finish the correction work. That is why the same orphaned accounts, stale entitlements, and missing ownership records return every quarter. The discipline should shift from finding issues to proving that remediation closes them before the next cycle.
A few things that frame the scale:
- 1 in 4 organisations are already investing in dedicated NHI security capabilities, with an additional 60% planning to do so within the next twelve months, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, according to the same study.
A question worth separating out:
Q: Who is accountable when orphaned accounts and stale NHIs keep showing up in audits?
A: Accountability sits with the control owners who define scope, the application owners who maintain source records, and the IAM team that runs the process. If orphaned accounts and stale NHIs recur, the organisation has a governance failure, not just an audit issue. The response should focus on ownership, lifecycle enforcement, and measurable closure rates.
