What should organisations do first when cloud access feels too broad?

Why This Matters for Security Teams

When cloud access feels too broad, the problem is usually not one bad role but an access model that was allowed to grow faster than the environment. Over time, teams accumulate default credentials, overlapping permissions, and persistent admin paths across cloud, Kubernetes, CI/CD, and support tooling. That is exactly the pattern highlighted in the Ultimate Guide to NHIs, where hidden non-human access often outlives the system that created it. The practical risk is lateral movement, secret reuse, and privilege creep that ordinary access reviews miss.

Security teams also need to distinguish between human access hygiene and NHI governance. The OWASP Non-Human Identity Top 10 treats overly broad machine access as a distinct failure mode because workloads scale faster than review processes. In cloud environments, that means the first pass is not a fine-tuned policy exercise. It is inventory, exposure mapping, and removal of standing privilege that has no current business justification.

In practice, many security teams discover the real blast radius only after a breach drill, a compromised token, or a surprise audit exposes just how many non-human identities were never formally owned.

How It Works in Practice

The first step is to map where privileged access actually exists, not where the IAM catalogue says it should exist. That includes cloud control planes, Kubernetes service accounts, build pipelines, secret stores, automation scripts, and any identity used by agents or services. For cloud and Kubernetes, the question is not simply whether a role exists, but whether it is still needed, whether it is too broad, and whether it is backed by long-lived secrets or persistent keys. NHI Management Group’s research shows that organisations routinely underestimate this sprawl, especially when access is shared across teams and environments.

A practical workflow looks like this:

• Inventory all privileged non-human identities, including default credentials, break-glass paths, and inherited roles.
• Map each identity to an owner, workload, environment, and current business purpose.
• Remove any default or unused credentials first, before attempting major redesign.
• Replace persistent admin access with tighter approval, logging, and time-bound elevation where possible.
• Shift from static secrets to short-lived credentials and workload identity for systems that can support it.

This approach aligns with current guidance from the CISA Zero Trust Maturity Model, which emphasizes continuous verification and reduced implicit trust, and it also fits the direction of the 2024 Non-Human Identity Security Report, where 88.5% of organisations said their non-human IAM practices lag behind or only match human IAM. The operational goal is simple: remove standing access wherever the workload does not truly need it, then introduce approval and logging around the exceptions that remain.

These controls tend to break down when teams rely on shared service accounts for legacy platforms, because ownership is unclear and any permission change risks outage.

Common Variations and Edge Cases

Tighter cloud access often increases operational overhead, requiring organisations to balance faster automation against slower change approval and more frequent credential renewal. That tradeoff is especially visible in hybrid estates, where the same workload may touch AWS, Azure, GCP, and multiple Kubernetes clusters. In those environments, best practice is evolving, but current guidance suggests that broad roles should be narrowed before organisations attempt more advanced identity redesign.

One common edge case is vendor-managed tooling that cannot yet use modern workload identity. In that case, the safer interim step is to isolate the secret, constrain the role to the smallest possible resource set, and add aggressive monitoring for unusual use. Another is break-glass access: it should exist, but it should be rare, heavily logged, and reviewed after every use. The same applies to CI/CD runners and ephemeral automation that often inherit more privilege than the job requires.

The 2026 Infrastructure Identity Survey found that 67% of organisations still rely heavily on static credentials, which helps explain why over-broad access remains common even after formal IAM programmes are in place. The practical lesson is that cloud access rarely feels too broad because of one obvious control failure. It feels broad because no one has yet traced the full chain from workload to credential to privilege to business owner.
