They don’t get a badge or a login. They get a service account, an IAM role, or an API key, just like any other non-human identity running in your environment. Mechanically, there’s nothing new.</p><p>What’s new is how many of them are being deployed, how fast, and with how much access. Most AI agents are running with far more permissions than their work requires. Sonrai computed <a href="https://sonraisecurity.com/cloud-access-data-report/">92% of cloud identities</a> are overprivileged and the proliferation of agents only further exacerbates that. When an agent is compromised or behaves outside of scope, overprivileged access turns a small incident into a serious breach.</p><p>Below we cover why <a href="https://sonraisecurity.com/blog/theres-a-new-way-to-do-least-privilege/">least privilege</a> applies to AI agents, and how to enforce it without manual work.</p><h2 class="wp-block-heading"><strong>Why Identity Risk Exists at Scale in Cloud Environments</strong></h2><p>Cloud environments aren’t built around a small number of controlled identities. They contain thousands of human and non-human identities, each with hundreds or thousands of permissions attached.</p><p>Those permissions are typically:</p><ul class="wp-block-list"> <li>Granted upfront during deployment</li> <li>Based on templates or convenience</li> <li>Rarely reviewed or removed later</li> </ul><p>Over time, the result is predictable:</p><ul class="wp-block-list"> <li>Most permissions go unused</li> <li>No one has full visibility</li> <li>Reducing access becomes risky, because one wrong permission change on a running workload can cause an outage</li> </ul><p>AI agents are being added into this already complex environment. They inherit the same overpermissioned patterns.</p><h2 class="wp-block-heading"><strong>What Makes AI Agent Identities Different</strong></h2><p>AI agents are assigned cloud IAM identities to call APIs, access storage, and trigger actions. They often inherit broad permissions at setup, and those permissions are rarely scoped down later.</p><p>Unlike human users, agents operate continuously and at high speed without human review between actions. A single compromised or malfunctioning agent with excessive permissions can affect multiple resources across an environment before anyone notices.</p><h2 class="wp-block-heading"><strong>Why Traditional IAM Approaches Fall Short</strong></h2><p>Standard IAM reviews were built around human users and scheduled audit cycles. AI agents can be spun up in minutes, and permissions reviews lag far behind deployment.</p><p>CIEM and visibility tools surface the problem but leave remediation to manual ticket queues. By the time a ticket is resolved, the risk has already existed for weeks or months.</p><p>The problem isn’t awareness – it’s enforcement.</p><h2 class="wp-block-heading"><strong>What Overprivileged AI Agents Enable</strong></h2><p>When an <a href="https://sonraisecurity.com/blog/aws-agentcore-privilege-escalation-bedrock-scp-fix/">AI agent is overprivileged,</a> the potential impact expands far and wide.. Depending on its access, an agent can:</p><ul class="wp-block-list"> <li>Read or exfiltrate sensitive data</li> <li>Modify or delete resources</li> <li>Move laterally across accounts</li> <li>Escalate privileges or trigger downstream systems</li> </ul><p>Speed and autonomy amplify every one of these. An agent executes in seconds. By the time anyone notices, the actions are done. These actions aren’t always done maliciously. A well-intended employee may use an agent to complete a task (e.g. reduce cloud costs) and the agent finds an imaginative way to do so that wasn’t ever intended (e.g. delete data storage)</p><h2 class="wp-block-heading"><strong>Why Least Privilege Is the Right Control for AI Agents</strong></h2><p>Least privilege means each identity, including AI agents, holds only the permissions it actively uses. If an agent does not have permission to delete or exfiltrate, it cannot cause that class of damage. It doesn’t matter how it was prompted, jailbroken, or exploited. The action isn’t available to it.</p><p>This is more reliable than trying to interpret or predict agent intent at runtime. You can’t reasonably anticipate every way an agent might be manipulated or misused. You can constrain the set of actions it’s capable of taking. If the agent can’t do unauthorized things, the sophistication of the attack doesn’t matter.</p><p>This is the same principle applied to human and non-human identities. It applies equally to AI agents.</p><h2 class="wp-block-heading"><strong>How Sonrai Enforces Least Privilege for AI Agent Identities</strong></h2><p>Sonrai’s <a href="https://sonraisecurity.com/cloud-security-platform/cloud-permissions-firewall/">Cloud Permissions Firewall</a> identifies all identities in the cloud environment, including AI agent identities. It maps which permissions each agent actually uses and flags unused privileged permissions for removal.</p><p>Here’s what enforcement looks like in practice:</p><ul class="wp-block-list"> <li><strong>One-click org-level controls.</strong> Org-level cloud-native controls are deployed to block unused permissions across all accounts at once.</li> <li><strong>Permissions on Demand.</strong> If an agent needs a permission for a specific task, the JIT request is made through Slack or Teams, approved, and granted in seconds. Access is revoked when the task ends.</li> <li><strong>No extra infrastructure.</strong> Controls are enforced using native AWS, GCP and Azure capabilities. Nothing is installed in the data path.</li> </ul><p>Customers reach enforced least privilege in hours, not quarters. DevOps keeps moving. Default-deny stays in place as you add new identities.</p><div class="wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex"> <div class="wp-block-button"><a class="wp-block-button__link wp-element-button" href="https://sonraisecurity.com/cloud-permissions-firewall-roi/">See How Cloud Permissions Firewall Gets You to Least Privilege Faster</a></div> </div><h2 class="wp-block-heading"><strong>What “Accepted State” Means for AI Agents</strong></h2><p>Accepted State is the defined boundary of permissions an identity is allowed to hold. For AI agents, this means locking permissions to what the agent needs for its actual workload.</p><p>Permissions outside the Accepted State are blocked at the policy layer, not just flagged in a report. When an agent’s scope legitimately changes, the Accepted State is updated through a governed, auditable process instead of quietly expanded by whoever has console access.</p><h2 class="wp-block-heading"><strong>Conclusion</strong></h2><p>AI agents are cloud identities, and they carry the same access risk as any other overprivileged identity in your environment, amplified by speed and autonomy.</p><p>Least privilege is not a new concept being applied to AI. It’s the same standard that should govern every identity. The gap is enforcement, not awareness. Sonrai closes that gap by automating policy deployment at the org level, using native cloud controls, making least privilege actually achievable – without disrupting running workloads.</p><h2 class="wp-block-heading"><strong>Frequently Asked Questions</strong></h2><h3 class="wp-block-heading"><strong>Do AI agents need separate IAM identities or can they share roles?</strong></h3><p>In a perfect world, every agent would have its own identity — that gives you clean attribution during incidents and contains the blast radius of any single compromise. But functionally, that’s rarely realistic at scale. The more practical focus is hardening the permissions attached to the roles agents actually share. Scope each role tightly to the specific actions and resources its workloads genuinely need, enforce short-lived credentials, and invest in logging that captures enough context to reconstruct attribution even when the IAM identity isn’t unique. </p><h3 class="wp-block-heading"><strong>What is “Accepted State” in the context of AI agent permissions?</strong></h3><p>Accepted State is the defined permissions boundary for a given identity. For an AI agent, it’s the set of permissions the agent actually needs to perform its workload. Anything outside that boundary is blocked by policy, not just flagged as a risk. When the agent’s scope changes, the Accepted State is updated through a controlled process.</p><h3 class="wp-block-heading"><strong>How does Sonrai handle AI agents that need temporary elevated access?</strong></h3><p>Through Privileges-on-Demand. Privileged permissions are blocked by default. When an agent or its owner needs elevated access for a specific task, a Just-in-Time access request can be requested or automated via Slack, Teams, or an existing ticketing workflow. Access is granted for the duration of the task and revoked automatically when it ends. The exploitation window for a compromised credential shrinks from indefinite to near-zero.</p><h3 class="wp-block-heading"><strong>Does enforcing least privilege for AI agents break their workflows?</strong></h3><p>Not if it’s based on actual usage. Sonrai analyzes what each agent is currently using before anything is blocked. What gets restricted is unused access, permissions that were granted but never exercised. Removing those doesn’t affect the agent’s ability to do its job. For permissions an agent occasionally needs, Privileges-on-Demand provides a controlled path without making them standing privileges.</p><h3 class="wp-block-heading"><strong>How is AI agent identity security different from non-human identity (NHI) security?</strong></h3><p>Mechanically, it isn’t. An agent authenticates and acts through the same IAM primitives as any other NHI. What’s different is behavior. Agents make decisions in context and can take a wider range of actions than a static automation script. That’s exactly why enforcement at the permissions layer matters more for agents. You can’t reliably predict every action an agent might take, but you can constrain the set of actions it’s capable of taking.</p><h3 class="wp-block-heading"><strong>What cloud environments does Sonrai support for AI agent identity enforcement?</strong></h3><p>Sonrai’s Cloud Permissions Firewall enforces controls natively in AWS, GCP and Azure using the providers’ own policy mechanisms, including AWS Service Control Policies at the org level. Nothing is installed in the data path, so there’s no added latency and no new infrastructure to manage.</p><div class="spu-placeholder" style="display:none"></div><div class="addtoany_share_save_container addtoany_content addtoany_content_bottom"><div class="a2a_kit a2a_kit_size_20 addtoany_list" data-a2a-url="https://securityboulevard.com/2026/04/why-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically/" data-a2a-title="Why AI Agents Need Least Privilege Too, and How to Enforce It Automatically"><a class="a2a_button_twitter" href="https://www.addtoany.com/add_to/twitter?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2026%2F04%2Fwhy-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically%2F&linkname=Why%20AI%20Agents%20Need%20Least%20Privilege%20Too%2C%20and%20How%20to%20Enforce%20It%20Automatically" title="Twitter" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_linkedin" href="https://www.addtoany.com/add_to/linkedin?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2026%2F04%2Fwhy-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically%2F&linkname=Why%20AI%20Agents%20Need%20Least%20Privilege%20Too%2C%20and%20How%20to%20Enforce%20It%20Automatically" title="LinkedIn" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_facebook" href="https://www.addtoany.com/add_to/facebook?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2026%2F04%2Fwhy-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically%2F&linkname=Why%20AI%20Agents%20Need%20Least%20Privilege%20Too%2C%20and%20How%20to%20Enforce%20It%20Automatically" title="Facebook" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_reddit" href="https://www.addtoany.com/add_to/reddit?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2026%2F04%2Fwhy-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically%2F&linkname=Why%20AI%20Agents%20Need%20Least%20Privilege%20Too%2C%20and%20How%20to%20Enforce%20It%20Automatically" title="Reddit" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_email" href="https://www.addtoany.com/add_to/email?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2026%2F04%2Fwhy-ai-agents-need-least-privilege-too-and-how-to-enforce-it-automatically%2F&linkname=Why%20AI%20Agents%20Need%20Least%20Privilege%20Too%2C%20and%20How%20to%20Enforce%20It%20Automatically" title="Email" rel="nofollow noopener" target="_blank"></a><a class="a2a_dd addtoany_share_save addtoany_share" href="https://www.addtoany.com/share"></a></div></div><p class="syndicated-attribution">*** This is a Security Bloggers Network syndicated blog from <a href="https://sonraisecurity.com/">Sonrai | Enterprise Cloud Security Platform</a> authored by <a href="https://securityboulevard.com/author/0/" title="Read other posts by Tally Shea">Tally Shea</a>.
