TL;DR: IAM adoption now sits at 95% and the market is expected to reach $45 billion by 2032, but Unixi’s analysis shows that scaling identity governance, de-provisioning, password discipline, compliance, and third-party integrations remain the five recurring failure points. The core problem is not IAM coverage, but keeping access decisions aligned with organisational change.
NHIMG editorial — based on content published by Unixi: the top 5 IAM challenges growing organisations face
By the numbers:
- IAM adoption is at 95% across corporate cybersecurity programmes, showing how widely the control has been deployed.
Questions worth separating out
Q: How should security teams manage IAM as organisations scale?
A: They should move from directory administration to full identity governance.
Q: When does de-provisioning become a security issue rather than an admin task?
A: It becomes a security issue whenever access outlives the role that justified it.
Q: What do teams get wrong about password management in IAM programmes?
A: They often assume password management is solved once the primary identity provider offers self-service reset.
Practitioner guidance
- Map access governance by identity type Separate human users, machine identities, and third-party connections in your IAM inventory so governance rules match the actor being controlled.
- Shorten de-provisioning workflows Trigger immediate access removal when a role change or departure event occurs, and extend the check to cloud and SaaS systems that sit outside the core directory.
- Harden privileged credential handling Eliminate shared administrator passwords, require strong password policy enforcement, and review where informal credential sharing still bypasses IAM.

Unixi's full analysis covers the operational detail this post intentionally leaves for the source:
- A fuller breakdown of how IAM and IGA controls diverge as organisations add cloud, SaaS, and branch-office complexity.
- The article’s examples of de-provisioning lag across role changes, departures, and externalised identity systems.
- Specific commentary on password policy, shared credential behaviour, and the limits of IAM visibility.
- The integration dependencies that can break access continuity when MFA, SSO, or security tools fail.

IAM scaling problems are really governance problems. Once access decisions have to span offices, cloud services, SaaS applications, and software identities, the original assumption of centralised control starts to erode. That is why identity governance, not just authentication tooling, becomes the control that holds the programme together. Practitioners should read scaling as a signal that the identity model has outgrown its original operating assumptions.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which means most teams cannot reliably prove what their non-human identities can do.
A question worth separating out:
Q: Who is accountable when a homegrown IAM process fails an audit or leaves access active too long?
A: The accountable owner is the identity and access governance function, even when the failure originated in custom code or an inherited script. Frameworks such as the NIST Cybersecurity Framework expect organisations to assign ownership, document controls, and maintain evidence for access decisions.
