What breaks when access approvals depend on manual coordination across multiple teams?

Why This Matters for Security Teams

When access approvals depend on manual coordination, security stops being a control function and becomes a routing problem. Every handoff adds delay, and every delay expands the window in which excessive access, stale approvals, or mis-scoped permissions can persist. That matters most for non-human identities, where access is often machine-speed and the blast radius can grow before anyone notices. NHI Management Group has documented how common weak governance is around NHIs, including the fact that only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs.

Manual coordination also undermines auditability. Approvers often rely on partial context, local spreadsheets, or informal chat threads, which makes it difficult to prove why access was granted, whether the request matched policy, and who owned the decision. That problem is amplified when access touches secrets, service accounts, API keys, or cloud resources with intertwined dependencies. The OWASP Non-Human Identity Top 10 treats weak lifecycle and approval discipline as a core risk because identity sprawl is rarely caused by one bad decision. In practice, many security teams encounter overprivileged access only after a break-glass exception has already become the default workflow.

How It Works in Practice

The failure mode is usually not a single missed approval. It is the cumulative effect of multiple teams each owning a fragment of the decision: application owners know the business need, platform teams know the resource, security teams know the policy, and operations teams know the timing. When those fragments are coordinated manually, access decisions become slow, inconsistent, and hard to revoke cleanly.

A more reliable model is to replace manual orchestration with policy-driven, identity-aware workflow. That means approvals should be evaluated against current context, not only against a request form. For NHI use cases, that context includes workload identity, intended resource, duration, environment, and whether the access is ephemeral or standing. NIST guidance on access control in SP 800-53 Rev. 5 supports this direction through enforced authorization, accountability, and least privilege.

• Use a single policy decision point so teams are not re-creating the same approval logic in separate tools.
• Bind approval to the identity of the requester, not just the ticket number or team name.
• Set short time-to-live values for access grants and require automatic expiry where possible.
• Log the full chain of custody so revocation is as visible as approval.

This is especially important for secrets and API credentials because once they are distributed manually, revocation becomes a scavenger hunt across pipelines, vaults, and code repositories. The NHI Management Group guide notes that 71% of NHIs are not rotated within recommended time frames in the Ultimate Guide to NHIs — Key Challenges and Risks, which shows how easily approvals and lifecycle control drift apart. These controls tend to break down when emergency access is handled through ad hoc chat approvals because the real owner, the real risk, and the real expiry date are no longer enforced together.

Common Variations and Edge Cases

Tighter approval control often increases coordination overhead, requiring organisations to balance speed against assurance. That tradeoff becomes visible in environments with regulated workloads, cross-functional change windows, or multi-cloud access paths where no single team can see the full dependency chain.

Current guidance suggests there is no universal standard for how many approvers are enough. Some organisations use dual approval for high-risk access, while others rely on policy thresholds and compensating controls. The practical distinction is whether the approval is merely ceremonial or truly risk-reducing. If access can be approved without understanding the target system, credential type, and expected duration, the workflow is not controlling risk, it is documenting it after the fact.

Edge cases also matter for service accounts, CI/CD pipelines, and break-glass roles. These often need faster provisioning than human requests, but faster does not mean freer. The control objective is to reduce coordination friction without reintroducing standing privilege. For teams that still depend on multi-team signoff, the best near-term improvement is usually to pre-approve policy patterns, not individual exceptions, and to reserve manual review for unusual or high-impact access only.
