TL;DR: AI as a service lowers the barrier to enterprise AI adoption by delivering pre-trained models, APIs, and managed workflows over the cloud, but it also shifts control, privacy, and identity risk to external platforms, according to WitnessAI. The practical issue is not access to AI itself, but whether IAM, NHI, and governance programmes can keep pace with where the decision-making now sits.
NHIMG editorial — based on content published by WitnessAI: AI as a Service: What It Is and How It Works
By the numbers:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
Questions worth separating out
Q: How should security teams govern AI as a service integrations in enterprise environments?
A: Security teams should govern AIaaS like any other identity-dependent workload.
Q: Why do AI as a service platforms create more identity risk than ordinary SaaS tools?
A: AIaaS often reaches deeper into data and automation than ordinary SaaS because it is embedded inside workflows, applications, and decision chains.
Q: What do organisations get wrong about access control for AI-powered workflows?
A: They often treat the model as the main control point and ignore the identity that is calling it.
Practitioner guidance
- Inventory every AIaaS integration Identify each API, SDK, and no-code connector that consumes external AI services.
- Replace static API keys with short-lived access Move AIaaS connections toward federated workload identity, scoped tokens, and secrets rotation where federation is not yet available.
- Fold AIaaS into lifecycle governance Put AI integrations into joiner-mover-leaver, recertification, and offboarding processes.

WitnessAI's full article covers the operational detail this post intentionally leaves for the source:
- Platform-by-platform explanation of AIaaS delivery models, including APIs, SDKs, and no-code integration paths.
- Vendor-led breakdown of core features such as monitoring, privacy controls, and ecosystem compatibility for enterprise deployment.
- Use-case examples that show how AIaaS is applied across customer support, fraud detection, healthcare, and supply chain workflows.
- Practical purchasing considerations around scalability, transparency, and governance capabilities for teams evaluating AI services.

AIaaS creates an identity control problem before it creates an AI capability problem. Enterprises often evaluate AIaaS as a platform choice, but the real issue is where authentication, authorisation, and data access land once the service is embedded in workflows. That makes AIaaS a governance extension of IAM and NHI, not a separate technology category. The practitioner conclusion is simple: if the identity boundary is unclear, the AI boundary is already too broad.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to The 2026 Infrastructure Identity Survey.
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to The 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do IAM and NHI programmes adapt when AI services are embedded in business processes?
A: They should extend existing governance to AI integrations rather than creating a separate exception path. That includes ownership, approval, recertification, offboarding, and logging for every AI-related credential or workflow so the control model remains consistent across human, machine, and AI-enabled access.
