TL;DR: Agent trust now depends on interaction-layer classification, not network-layer identity alone, because legitimate and malicious AI agents can look the same until behavior reveals intent, according to Arkose Labs. The underlying governance problem is that conventional IAM assumptions break when identity can be spoofed but solve patterns, timing, and session behaviour still expose risk.
Editorial analysis by NHI Mgmt Group, based on content published by Arkose Labs: “Intent, Not Identity: Built for the Era of AI Agents”.
Key questions
Q: How should organisations classify AI agents when identity signals are not enough?
A: They should classify agents using interaction evidence, not just authentication claims.
Q: Why do behavioural controls matter more than identity alone for AI agents?
A: Because identity can be spoofed, delegated, or hidden, while behaviour still reflects how an agent operates.
Q: What breaks when agent trust is handled as a binary allow or block decision?
A: Binary decisions either let too much ambiguous automation through or block legitimate agents that support real business activity.
Practitioner guidance
- Define agent trust classes Separate self-disclosing good agents, non-disclosing good agents, and malicious adversaries into explicit policy classes so response is based on observed behaviour, not a single automation label.
- Preserve challenge telemetry Treat solve timing, retry patterns, and session behaviour as durable security signals and retain them for policy tuning, fraud review, and escalation decisions.
- Use graduated enforcement Implement allow, monitor, challenge, throttle, and block actions so ambiguous sessions can be constrained without disabling all legitimate agentic commerce.
Bottom line: Agent trust is moving from static identity checks toward behavioural verification because AI agents can impersonate conventional access signals while still exposing intent in how they interact.

Behavioural verification is becoming the missing trust control for AI agents. Identity credentials can be copied, delegated, or hidden, but interaction patterns still expose how an agent operates in practice. That makes behavioural evidence the most useful control plane when multiple agent populations share the same technical access paths. Practitioners should treat behaviour as an access attribute, not just an investigation clue.
A few things that frame the scale:
- 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do IAM and data security teams align on AI governance?
A: They should align around the same control objective: explainable access to sensitive data. IAM teams own entitlements and identity review, while data teams own classification and lineage, but AI risk emerges where those controls overlap. The best programmes treat access path visibility as a shared requirement.
