By NHI Mgmt Group Editorial TeamBased on DTEX: “Agentic AI: The Star of RSAC 2026” (April 6, 2026)

TL;DR: RSAC 2026 was dominated by agentic AI, with security leaders discussing a market where adoption is accelerating faster than governance, control and isolation capabilities, according to DTEX, while new research cited in the article shows major gaps in purpose limits, shutdown and network separation. The defining risk is not AI as a tool, but AI behaving like a new insider that can act at machine speed before humans can intervene.


At a glance

What this is: DTEX frames RSAC 2026 as a marker of how agentic AI has moved from buzzword to operational risk, with adoption racing ahead of governance and control.

Why it matters: IAM, PAM and AI security teams need to treat agentic systems as governable identities with bounded purpose, revocation paths and isolation controls, not as ordinary automation.

By the numbers:

  • 650 vendors had exhibits at RSAC 2026, with almost every one emphasizing agentic AI.
  • 63% of organisations cannot enforce purpose limitations on their AI agents.
  • 60% cannot terminate an agent that’s misbehaving.
  • 55% cannot isolate AI systems from their broader networks.

Context

Agentic AI is software that can choose actions, tools and timing with limited human input. In security programmes, that changes the governance problem from managing static access to managing delegated behaviour, revocation and containment across systems and data. Agentic AI identity guide is the right foundation for understanding why this shift is different from ordinary automation.

RSAC 2026 appears to have accelerated that shift into mainstream security planning, but the underlying control gap is older than the conference theme. Organisations are adopting AI faster than they can define purpose, limit scope, or prove they can shut systems down when behaviour changes.

The typical starting position is now increasingly inadequate: teams often have more experimentation than governance, and more enthusiasm for deployment than confidence in control. That imbalance is exactly where shadow AI and agentic risk begin.


Key questions

Q: What breaks when organisations deploy AI agents without lifecycle governance?

A: What breaks is not only access control but the assumption that deployment is a one-time event. Without lifecycle governance, agents can be promoted, altered, and left running without clear offboarding, validation, or reassessment. That leaves blind spots in ownership, behaviour drift, and risk acceptance.

Q: Why does machine-speed agent behaviour change access governance?

A: Machine-speed behaviour collapses the time available for manual review, exception handling and human approval. If an agent can request, use and drop privileges inside one workflow, governance must happen before action and during runtime, not after the fact.

Q: What are the signs that shadow AI is becoming a governance problem rather than a productivity aid?

A: The clearest signs are widespread use outside IT visibility, repeated sharing of corporate data with GenAI tools, and no consistent approval path for new applications. If employees are using AI because no sanctioned option exists, or if security teams cannot see which tools are active, the issue has moved from isolated behaviour to unmanaged risk.

Q: How should security teams respond when AI agents start touching OT data and workflows?

A: They should treat the agent as a governed identity with tightly bounded access, not as a generic automation layer. The practical test is whether the agent’s data access, decision scope and action rights can be limited, reviewed and revoked before it reaches production control paths.


Technical breakdown

How agentic systems become identity-bearing actors

An agentic system becomes a security concern when it can independently select tools, requests and timing, not merely when it produces output. Once it can act across workflows, the control problem shifts to identity, delegation and scope. The system may hold credentials, inherit permissions or request access dynamically, which makes its behaviour closer to a governed principal than a simple application. That is why the key question is not whether an AI tool exists, but whether its runtime actions are bounded, attributable and revocable. Practical implication: treat every agent with access as an identity lifecycle problem, not just a model deployment problem.

Practical implication: define registration, delegation and revocation for every agent before it touches production systems.

Why standing access breaks under machine-speed behaviour

Traditional access governance assumes a human or service account will keep privileges long enough to review them later. Agentic systems can request, use and discard access inside the same workflow, which compresses the control window to the point where post hoc review is too late. If an agent can act without human approval, the real control point becomes issuance time, policy evaluation time and runtime containment. That is why purpose limitation, network isolation and rapid termination matter more than retrospective audit alone. Practical implication: move controls from review after use to decision before use. See the AI Agent Authorisation Guide.

Practical implication: enforce task-scoped access decisions before the agent can reach sensitive systems.

Shadow AI turns insider risk into an instrumentation problem

Shadow AI matters because it lets employees introduce agentic behaviour outside approved governance paths, often with legitimate intent but without equivalent controls. That means the organisation may not see the agent, its prompts, its data access or its tool chain until damage is underway. This is similar to shadow IT, but the operational risk is sharper because agent decisions can happen at machine speed and across multiple systems. The governance response is therefore discovery, behavioural monitoring and controlled intake, not simply prohibition. Practical implication: build visibility for unsanctioned agents before they reach sensitive data. See the AI Agent Observability, Audit and Incident Response Guide.

Practical implication: create an inventory of sanctioned and unsanctioned agents across endpoints, SaaS and internal workflows.


Threat narrative

Attacker objective: The objective is to exploit the organisation’s governance gap so agentic behaviour can reach sensitive systems before containment or revocation is possible.

  1. Entry occurs when employees or vendors introduce agentic AI into the environment faster than formal governance can track it.
  2. Credential and access exposure follows when those agents are connected to internal systems, data stores or workflows with excessive scope.
  3. Escalation happens at machine speed when a misbehaving agent takes unexpected actions before humans can intervene.
  4. Impact is the shrinking of the action-to-damage window, with possible data exposure, workflow corruption or uncontrolled system changes.

NHI Mgmt Group analysis

Agentic AI has become an identity governance problem before it becomes a model governance problem. The article shows that the hard part is not adopting agents, but defining what they are allowed to do, what they can access and how they are retired. That makes registration, delegation and revocation central controls, not optional administration. Practitioners should treat agent identity as a first-class governance object.

Shadow AI is the enterprise’s new untracked insider. The article’s strongest point is that employees can attach AI to real systems without corresponding control maturity, which creates risk even when intent is benign. This is a governance failure, not just a user behaviour issue, because the business has encouraged speed without providing guardrails. The right response is sanctioned visibility, not blind prohibition.

Purpose limitation gap: the article exposes a specific control failure where organisations cannot reliably constrain an agent to the task it was meant to perform. When 63% cannot enforce purpose limits and 60% cannot terminate misbehaving agents, the gap is not theoretical. It means governance is being measured after deployment instead of being enforced at runtime. Practitioners should see this as a design flaw in agent control architecture.

Machine-speed behaviour collapses the usefulness of human-paced review. Once multiple agents can act in parallel, the window between action and impact becomes too short for manual intervention to be an effective primary defence. That does not eliminate audit, but it changes its role from prevention to evidence. Security teams should redesign controls around pre-issuance policy, runtime isolation and rapid shutdown.

Agentic AI will force convergence between IAM, PAM and AI security governance. Agents that operate like digital coworkers need identity, privilege and behavioural boundaries that span traditional silos. The article signals that organisations will not secure this category with model prompts alone or with IAM alone. Practitioners should align access policy, monitoring and offboarding across both human and machine actors.

What this signals

Agentic AI governance debt: the longer organisations let experimentation outrun identity and access policy, the more control they defer into a runtime crisis. The immediate issue is not model quality, but whether the enterprise can prove who or what an agent is allowed to become. Zero trust for AI agents is increasingly the right control lens for that question.

The operational signal is clear: security teams should expect more agent inventories, more delegated access decisions and more pressure to distinguish sanctioned automation from shadow AI. That will pull IAM, PAM and SOC workflows closer together, especially where one agent can touch many systems in a single session.


For practitioners

  • Build an agent inventory with ownership and purpose Record every approved agent, its owner, intended task, connected data sources and permitted tools so governance starts with a real inventory rather than assumptions.
  • Enforce task-scoped access decisions Require policy checks at issuance time so agents receive only the minimum access needed for the specific workflow and cannot accumulate standing privilege. See the AI Agent Authorisation Guide.
  • Add termination and isolation controls for misbehaving agents Define the kill switch, isolation boundary and escalation path before deployment so a rogue agent can be contained without waiting for manual investigation. See the AI Agent Observability, Audit and Incident Response Guide.
  • Separate sanctioned AI from shadow AI workflows Create an intake path for employee-created agents, including review, logging and network restrictions, so experimentation does not bypass control design. See the Agentic AI Security Guide.

Key takeaways

  • Agentic AI is becoming a governance problem because organisations are granting software the ability to act, not just to assist.
  • The article’s evidence points to a control gap in purpose limits, termination and network isolation, which means runtime governance is now as important as policy design.
  • Practitioners need agent inventory, task-scoped access and a tested shutdown path before broad deployment can be considered safe.

Key terms

  • Agentic AI: Autonomous AI systems capable of planning, deciding, and taking actions, including calling APIs, writing code, and orchestrating other agents, with minimal human oversight. Agentic AI introduces new NHI risks as agents must authenticate to external services.
  • Shadow AI: AI agents, copilots, or connected tools operating without full visibility or governance from security teams. Shadow AI becomes an identity problem when those systems authenticate with unmanaged tokens, service accounts, or OAuth apps that can reach production resources.
  • Purpose limitation: The rule that data should be used only for the specific business purpose allowed by policy and context. In AI environments, this means a dataset may be technically accessible but still inappropriate for a given model, assistant, or agent if the use case exceeds the approved scope.
  • Agent Offboarding: The process of formally retiring an AI agent by revoking credentials, detaching tools, closing access paths, and recording evidence that authority has ended. In NHI programs, offboarding is as important as onboarding because abandoned access is still active risk.
