TL;DR: Choosing between on-premises and cloud IAM is not a theory exercise, because compliance, legacy integrations, cost, security investment, and NHI sprawl all shift the risk profile, according to Soffid and Verizon. The decisive question is whether your identity model can sustain centralized control as cloud scale, third-party dependencies, and non-human identities increase.
NHIMG editorial — based on content published by Soffid: On Prem vs Cloud: Choosing the right IAM architecture
By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
Questions worth separating out
Q: How should security teams choose between on-premises and cloud IAM?
A: They should choose the model that can prove control ownership, auditability, and lifecycle governance for their actual environment.
Q: Why do cloud IAM migrations often expose hidden identity risk?
A: Cloud migrations expose hidden identity risk because IAM is bound to trust relationships, connectors, and delegated access paths that are easy to miss until they fail.
Q: What breaks when service accounts and permissions sprawl across hybrid environments?
A: Access reviews become incomplete, offboarding becomes inconsistent, and privileged credentials remain active long after teams believe they have been contained.
Practitioner guidance
- Map compliance to control ownership Document which IAM controls must remain directly managed on-premises and which can safely be inherited from cloud certifications, then test audit evidence for each requirement.
- Inventory legacy identity dependencies before migration Catalogue every connector, trust relationship, and authentication dependency that could fail during cloud transition, then assign an owner for each brittle integration.
- Centralise NHI governance across hybrid estates Bring service accounts, API keys, and workload credentials under one policy model so access review, rotation, and offboarding are not split across tools and teams.

Hybrid IAM does not fail because cloud is inherently weaker. It fails when organisations assume a single governance model can preserve the same control quality across on-premises estates, SaaS, and multicloud. The article surfaces that tension clearly, and the practical conclusion is that control location matters less than control consistency across the full identity lifecycle.
A few things that frame the scale:
- 88.5% of organisations acknowledge that their non-human IAM practices lag behind or are merely on par with their human identity and access management efforts, according to The 2024 Non-Human Identity Security Report.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Who is accountable when IAM control gaps appear in cloud or on-premises models?
A: The organisation remains accountable regardless of deployment model, because outsourcing infrastructure does not outsource governance. Security, IAM, and platform teams need clear ownership for lifecycle controls, evidence collection, and third-party trust decisions before audit or breach conditions expose the gap.
