The NHI Sprawl Reality

The identity landscape has shifted dramatically in recent years:

For every 1 human identity, enterprises now manage 50+ non-human identities (NHI) — service accounts, APIs, workloads, bots, and agents. With AI agents and autonomous pipelines proliferating, this ratio will only grow. Regulators are signaling that every identity — human or machine — must be governed, verified, and auditable.

This creates a massive governance challenge for Identity Security teams. The opportunity isn’t in chasing AI buzzwords, but in solving the governance gaps that AI makes urgent.

Global AI Governance Landscape

Governments worldwide are shaping AI regulation with different approaches but converging expectations: transparency, accountability, and traceability of access.

European Union – AI Act First comprehensive horizontal AI regulation. Strong focus on risk classification, accountability, and transparency. Identity Impact: Requires auditable access controls and accountability logs — classic IAM/IGA ground.

United States – AI Action Plan & NIST AI RMF Decentralized, sector-specific approach. Encourages innovation while offering voluntary frameworks. Identity Impact: Pushes for sector-driven IAM standards — least privilege, contextual access, continuous authentication.

China – Generative AI Regulations Early rollout of binding rules for generative AI (since 2023). Heavy state oversight and mandatory compliance. Identity Impact: Centralized enforcement with mandatory verification and tight access governance.

Singapore – Model AI Governance Framework Flexible, best-practices-driven governance model. Global reference point for trust and accountability. Identity Impact: Emphasizes ecosystem-level governance and multi-stakeholder accountability.

United Kingdom – AI Safety Institute & AI Regulation Policy Moving from voluntary to binding requirements. Safety Institute created for testing and evaluating frontier models. Identity Impact: Clear need for segregation of duties (who trains vs who approves) and traceability of privileged access.

South Korea – AI Basic Act & Seoul Declaration Comprehensive AI law paired with an international declaration. Strong emphasis on interoperability and collaboration. Identity Impact: Cross-border compliance requires consistent IAM/IGA enforcement across jurisdictions.

Critical Evolution Areas for Identity Management

Global regulation is setting direction, but identity is where implementation happens. The industry must evolve in four areas:

  1. Bring AI Workloads Into Scope Identity systems must treat models, datasets, GPU clusters, and MLOps platforms as governed resources — with the same rigor as ERP or cloud apps.

  2. Strengthen Non-Human Identity Governance Service accounts, APIs, and AI agents need lifecycle management, credential rotation, and attestation with the same rigor as human identities.

  3. Enable AI-Aware Policies & Reviews Regulators want to know who trained, fine-tuned, deployed, or audited models. IAM/IGA must evolve separation of duties and access review workflows for AI’s unique lifecycle.

  4. Deliver Regulator-Grade Audit Trails Identity systems must produce end-to-end evidence: identity → dataset → model → action. This lineage will be compliance-critical, not optional.

Strategic Recommendations

  • Anchor on accountability: IAM/IGA must own the “who, when, under what controls” layer of AI governance.
  • Stay focused: Don’t drift into model bias or explainability — those belong to other domains.
  • Integrate broadly: Partner with MLOps, data governance, and AI security platforms to form a comprehensive trust fabric.
  • Lead on NHI sprawl: With human-to-NHI ratios climbing past 1:50, identity is uniquely positioned to bring order.

The Bottom Line

If identity management doesn’t adapt, it risks being sidelined as AI governance matures. If it does adapt successfully, IAM/IGA becomes the backbone of trust in the AI era — the system of record enabling compliance, accountability, and secure AI adoption at enterprise scale.
