Manual handling creates inconsistent evidence, delayed revocation, and repeated exceptions that auditors will ask you to explain. It also increases dependency on a few staff members who understand the process, which makes the control environment fragile and expensive to defend.
Why This Matters for Security Teams
Manual onboarding and termination for SOC 2 rarely fail as a single dramatic event. They fail as a pattern: inconsistent approvals, delayed deprovisioning, missing evidence, and exceptions that accumulate until the control can no longer be defended. For non-human identities, that matters because service accounts, API keys, and automation tokens do not wait for a ticket queue. When identity lifecycle work is handled by hand, the evidence trail becomes as fragile as the process itself.
NHI Management Group’s Ultimate Guide to NHIs notes that only 20% of organisations have formal offboarding and revocation processes for API keys, which is exactly the kind of gap auditors probe when they test control design and operating effectiveness. The OWASP Non-Human Identity Top 10 reinforces the risk: unmanaged secrets and stale identities are not administrative annoyances, they are active exposure paths. In practice, many security teams discover the weakness only after an auditor requests proof of timely removal and the evidence exists in emails, spreadsheets, or memory rather than a reliable system of record.
How It Works in Practice
SOC 2 expects a control environment that is repeatable, reviewable, and capable of producing evidence on demand. Manual onboarding and termination usually break that expectation in three places: request intake, approval, and completion proof. If access is granted through ad hoc messages or informal approvals, there is no consistent record of who requested what, who approved it, and when access was actually provisioned or revoked.
For NHI-heavy environments, the operational issue is even sharper. A service account may be created for a deployment pipeline, a temporary integration, or a third-party tool, then forgotten after the original owner changes roles. The NHI Lifecycle Management Guide is useful here because lifecycle discipline is what turns access management into evidence, not just intent. Current guidance suggests that organisations should tie onboarding to a named business purpose, a defined owner, and a reviewable approval path, then tie termination to an event that is provable, such as role change, contract end, system retirement, or ticket closure.
Practically, stronger programs use:
- Standard request templates with required fields for owner, system, purpose, and expiry.
- Automated provisioning and revocation where possible, with manual steps reserved for exceptions.
- Time-bound access for secrets, tokens, and service accounts rather than standing entitlements.
- Central logging that preserves the evidence chain from request to removal.
Security teams often pair this with policy-as-code and periodic recertification so that access is validated against the system of record rather than checked from memory. The CISA Zero Trust Architecture guidance is relevant because it reinforces the principle that access should be continuously verified, not assumed to remain valid. These controls tend to break down when access decisions are spread across email, chat, and one-off admin actions because the organisation can no longer prove completion, timeliness, or consistency.
Common Variations and Edge Cases
Tighter onboarding and termination controls often increase process overhead, requiring organisations to balance auditability against operational speed. That tradeoff is real, especially where engineering teams need rapid access for deployments, incident response, or vendor integrations. Best practice is evolving, but current guidance suggests that speed should come from automation and pre-approved patterns, not from bypassing control evidence.
Edge cases usually involve accounts that do not fit neatly into human-style joiner-mover-leaver workflows. Shared service accounts, break-glass access, CI/CD credentials, and third-party integrations often require different handling, but they still need an owner, an expiry strategy, and a documented removal path. The Top 10 NHI Issues highlights why this matters: excessive privilege and stale secrets make lifecycle failures expensive to ignore. For SOC 2, the key question is not whether every case is identical, but whether exceptions are controlled, approved, tracked, and reviewed.
That distinction becomes critical during acquisitions, emergency access, and vendor-led implementations, where organisations may inherit undocumented accounts or temporary credentials that never expire. In those environments, the control often fails because ownership is unclear and revocation depends on individuals rather than a workflow. Manual handling looks manageable until scale, staff turnover, or a credential incident exposes how little of the process is actually repeatable.

OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Manual access processes often leave NHI ownership and lifecycle controls undefined. |
| NIST CSF 2.0 | PR.AC-1 | Access provisioning and revocation must be controlled and traceable for SOC 2 evidence. |
| NIST AI RMF | Lifecycle governance needs accountability and documentation to support trustworthy AI-enabled operations. |
