What breaks when organisations manage machine and third-party access through manual processes?

Why This Matters for Security Teams

Manual access handling works until scale, speed, and audit pressure collide. For machine identities and third-party access, every human touchpoint adds delay, inconsistency, and a new failure mode: approvals drift by team, revocation slips behind onboarding, and no one can reliably prove who had access at a given moment. That is exactly why NHI Management Group highlights that only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs.

The risk is not just operational overhead. Manual workflows create orphaned identities, untracked exceptions, and brittle evidence for auditors. In the security literature, this aligns with the control gaps called out by the OWASP Non-Human Identity Top 10 and the visibility expectations in the NIST Cybersecurity Framework 2.0. In practice, many security teams discover the real cost only after an incident review shows access was never removed, or removed too late, rather than through deliberate control testing.

How It Works in Practice

When organisations manage machine and third-party access manually, the process usually depends on tickets, email approvals, spreadsheet tracking, and one-off reminders. That model fails because it treats access as a one-time administrative event instead of a lifecycle: request, approve, issue, review, rotate, and revoke. For NHI and partner access, that lifecycle needs to be visible and repeatable, as described in the NHI Lifecycle Management Guide.

Better practice is to replace handoffs with policy-driven automation. That usually means:

• centralising requests and approvals so the same entitlement is reviewed the same way every time
• linking access to an owner, purpose, and expiry date
• automating revocation when a contract ends, a workload is retired, or a token is no longer needed
• tracking evidence for auditors without relying on tribal knowledge

That approach also helps reduce exposure from secret sprawl, which NHIMG has documented extensively in the Top 10 NHI Issues and in breach-oriented analysis such as the 52 NHI Breaches Analysis. On the standards side, NIST SP 800-53 Rev 5 Security and Privacy Controls supports consistent account management, review, and revocation discipline, while NIST Cybersecurity Framework 2.0 reinforces governance and continuous oversight. These controls tend to break down in fast-moving engineering environments where access is granted through ad hoc exceptions because teams optimise for delivery speed over repeatable control enforcement.

Common Variations and Edge Cases

Tighter control often increases friction for developers, platform teams, and external partners, so organisations have to balance speed against assurance. That tradeoff is especially visible when access is needed for short-lived integrations, incident response, or vendor troubleshooting.

There is no universal standard for every manual process, but current guidance suggests the highest-risk cases deserve the strongest automation first: privileged service accounts, API keys, and third-party access with production reach. Low-risk, low-frequency requests may still use human approval, but they should not remain manually tracked indefinitely. The practical goal is not to eliminate all human review, but to eliminate human dependency for routine issuance and revocation.

Edge cases also matter. Some vendors require shared administrative access, some legacy systems cannot integrate with modern identity tooling, and some business owners resist expiry controls because they fear disruption. Those exceptions should be explicitly documented, time-bounded, and reviewed. When manual processes become the default for exceptions, the exception becomes the control failure. That is why a mature program pairs policy enforcement with escalation paths, not informal approvals.

For this reason, NHIMG’s research on lifecycle processes and key challenges is useful operationally, especially the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and Ultimate Guide to NHIs — Key Challenges and Risks. The recurring failure mode is not lack of policy, but manual handling that cannot keep pace with how quickly machine and third-party access changes in real environments.
