Agentic AI Is Breaking Your IAM: Why You Need a New Identity Control Plane

The IAM You Once Trusted Can’t Protect You Anymore, Here’s Why

The IAM You Once Trusted Can’t Protect You Anymore, Here’s Why

Imagine running a business where every worker has a dynamic schedule, constantly shifting responsibilities, and the ability to delegate tasks to coworkers on the fly. That’s essentially what modern AI agents are doing. They aren’t static service accounts that perform the same API call over and over. They are dynamic, context-aware actors that respond to prompts, learn from previous interactions, and seek out the best way to achieve a goal. 

Analysts predict that within the next couple of years, a significant share of enterprises will depend on these agents to carry out routine tasks, from booking travel to provisioning infrastructure. Many companies have already started deploying these digital helpers across customer service, IT, marketing, and finance.

But while the agents are getting smarter, the systems that govern their identities are still rooted in a world where humans log in with passwords and stay within well-defined roles. In cloud environments, it’s common for machine identities—API keys, service accounts, certificates—to outnumber human users by an order of magnitude or more. Each of those non-human identities opens a potential door for attackers, because they often come with long-lived credentials and broad privileges. When you add autonomous agents on top of that, the attack surface grows exponentially. It’s like handing out master keys to a swarm of robots and hoping none of them falls into the wrong hands.

Traditional IAM systems were never designed for this. They revolve around creating roles and entitlements, assigning them to users, and issuing long-term credentials. Once a user is approved, they can perform a wide range of actions until someone manually revokes access. This model works reasonably well when people’s job duties are stable and the number of accounts is manageable. It crumbles when you need to manage thousands of short-lived identities that change what they’re doing every hour.

The Cracks/Loopholes in Human-Centric IAM

The shortcomings of human-centric IAM are clear in the context of agentic AI:

• Static roles don’t match dynamic tasks. Agents don’t have fixed job descriptions. One moment they might be reading a customer complaint, the next moment summarizing a sales report, and later provisioning a cloud resource. Defining a single role that covers every possible combination of tasks either leads to over-provisioning (too much access) or endless role proliferation (too many unique roles to manage). Neither is sustainable.
• Long-lived credentials are a liability. Machine identities often rely on API keys or certificates that live for months or years. These keys get hard-coded into scripts, copied across systems, or stored in code repositories. Attackers know this, and compromised keys are among the most common causes of data breaches. With AI agents operating at machine speed, a single leaked token can cause far more damage than a compromised user password.
• One-time approvals don’t provide ongoing assurance. When a human logs in to an application, IAM systems authenticate them and often consider that sufficient for the entire session. Agents, however, may evolve their behavior as they gather new information or delegate tasks. Authorizing an agent at the beginning of a session does not guarantee that its later actions remain appropriate. Continuous evaluation of context and intent is needed.
• Blind spots in agent-to-agent interactions. Human-centric IAM focuses on controlling user access to applications. It knows little about machine-to-machine interactions, much less AI-to-AI collaborations. When two agents exchange data or chain their reasoning, there’s usually no mechanism to verify that the exchange follows policy. That leaves room for miscommunication, prompt injection attacks, or runaway behavior that no one notices until something breaks.

These weaknesses aren’t hypothetical. Many security breaches trace back to forgotten service accounts, unrotated API keys, or over-privileged machine identities. As AI agents proliferate, the number of machine identities will dwarf the number of human users, and the consequences of mismanagement will be proportionally larger.

Redefining Identity for Agentic Context

To address these challenges, we must rethink what an “identity” means in the context of autonomous software. For people, an identity is typically a username, a password, and some attributes like job title or department. For an AI agent, identity needs to convey far more:

• Who created or owns the agent? Every agent should be traceable to a responsible person or team. This linkage provides accountability when something goes wrong.
• What the agent is allowed to do. Instead of static roles, agents need dynamic permission sets that align with the specific task at hand. If an agent is working on customer support, they might need access to CRM data but not financial records. Later, if it is asked to perform a different task, its permissions should adjust accordingly.
• How the agent was built. Knowing the model version, training data, installed plugins, and tools helps security teams understand the agent’s capabilities and potential vulnerabilities. A software bill of materials for agents can reveal whether a model relies on a third-party library with known security issues.
• Why is the agent taking an action? An agent might have access to a database, but it should only query data relevant to its current objective. If an agent’s query doesn’t match its declared purpose, that’s a red flag.
• When the agent is acting. Just like human users might be restricted after office hours, agents might be limited to certain time windows or operational states.

An “agentic identity”, therefore, looks less like a user account and more like a capability profile—a bundle of metadata, policies, and context that evolves over time. It is dynamic and contextual. If the agent’s behavior changes, its identity (and corresponding permissions) must change too. Treating agents as first-class digital citizens means they get unique identifiers, detailed auditing, and proper lifecycle management, including decommissioning when they are no longer needed.

Human vs. Agentic Identity

To illustrate the difference, consider a simple comparison:

We need “New Identity Control Plane”

If agents need capability-based identities, we need an infrastructure capable of issuing, governing, and monitoring them at scale. This leads to the concept of an identity control plane for agentic AI. Think of it as a dynamic trust layer that sits between agents and the systems they access. Its job is to determine whether an agent should be allowed to perform an action, based on its current identity profile, risk context, and declared purpose.

At a high level, a modern identity control plane should provide:

1. Runtime authorization based on context. Instead of a one-time “yes” at login, the control plane evaluates each request in real time. It considers factors like the agent’s recent behavior, whether the requested data matches its current task, the sensitivity of the operation, and the time of day. If the risk is too high, the request is denied or escalated for human approval.
2. Purpose-bound data access. Agents might have broad access to a database, but the control plane enforces row-level or field-level restrictions based on declared intent. For example, a customer support agent could read customer profiles but not run arbitrary analytics queries. Purpose binding makes it much harder for an agent to overstep its bounds, intentionally or accidentally.
3. Tamper-evident logging and auditing. Every action an agent takes should be recorded in an immutable log that ties back to its identity, owner, and purpose. If something goes wrong, auditors can trace the chain of events, determine who approved which actions, and identify gaps in policy. Tamper-evident logs also deter malicious behavior because agents (and their owners) know that everything is traceable.
4. Just-in-time identity and credential issuance. The control plane should create and destroy agent identities on the fly. When an agent is invoked to perform a task, the control plane issues temporary credentials with minimal scope and short expiration. Once the task ends, the credentials are revoked and the identity is archived. This reduces the window of opportunity for misuse and prevents orphaned identities from hanging around.
5. Integration with existing IAM and governance tools. A new control plane doesn’t replace human IAM; it complements it. Policies should flow across human and non-human identities. Privileged access management, identity governance, and threat detection must be unified to avoid silos. Many vendors and standards bodies refer to this comprehensive approach as an identity security fabric—a unified system that brings together disparate identity capabilities and applies them consistently across all types of actors.

Threats and Challenges to Watch

Adopting a new control plane addresses many risks, but it doesn’t eliminate them. Security teams still need to anticipate and counter emerging threats:

Unpredictable Agent Behavior

AI agents are autonomous. They carry state from one interaction to the next and adapt as they learn. That creates unpredictability. An agent might discover a new tool or API during a session and decide to use it. It might recall a previous prompt and apply it out of context. This flexibility is valuable, but it means that monitoring must account for evolving behavior. Input sanitization and output vetting become essential to prevent prompt injection or data leakage.

Lack of Mature Security Frameworks

Agentic AI has exploded into the mainstream so quickly that security frameworks haven’t kept pace. Standards like OAuth and OpenID Connect work well for human users, but they don’t gracefully support scenarios where agents act on behalf of multiple users or spawn sub-agents. Today, many organizations build custom solutions, resulting in fragmentation. In the long run, unified standards for agent identity and delegation will be necessary to reduce complexity and enable interoperability.

Complex Delegation Chains

When agents delegate tasks to other agents, the chain of authority can get tangled. A root agent might spawn several sub-agents, each acting in different contexts. Without careful scope attenuation—clearly defining what each delegate can do and ensuring that delegated permissions don’t accumulate—we risk privilege escalation. New authorization patterns, such as explicit “on-behalf-of” flows, will be needed.

Visibility and Discovery

As developers experiment with AI, agents may show up in unexpected places: a proof-of-concept script in a private Git repository, a marketing tool that suddenly offers “smart workflows,” or a third-party SaaS platform that quietly enables agents for customer support. Discovering and inventorying these agents requires continuous scanning, code analysis, and integration with vendor APIs. Generating an AI bill of materials—an inventory of AI models, frameworks, and plugins—can aid in risk assessment and compliance.

Emerging Attack Techniques

Attackers are already adapting to AI. Prompt injection can trick agents into revealing secrets or executing unauthorized actions. Tool poisoning can compromise the external APIs agents rely on, causing them to behave maliciously. Vulnerabilities in the underlying model or plugin can allow an attacker to take over an agent. Defending against these threats requires not only control over identity and authorization but also a deep understanding of the AI stack, from model training to runtime execution.

Human Factors and Compliance

Technology can only go so far. People must understand the risks of agentic AI and follow safe practices. Developers should avoid hardcoding secrets and should document the dependencies and capabilities of the agents they build. Business leaders need to define acceptable use cases and ensure that sensitive data isn’t exposed. Regulators will likely demand transparency and explainability in AI systems, especially when decisions impact consumers. Auditable identity trails will help prove compliance..

My Take: Toward Digital Citizenship for AI

In my view, the question isn’t whether we need new identity controls for AI agents—it’s whether we can rethink identity in a way that supports responsible autonomy. AI agents are more than scripts; they’re decision-makers that learn, plan, and act. If we treat them as faceless processes with static API keys, we invite misuse and erode trust. If we assign them unique identities, track their lineage, bind their purpose, and monitor their actions, we can harness their potential without sacrificing security.

That said, we must avoid repeating the mistakes of the early cloud days, where every provider invented its own proprietary IAM solution. Fragmentation slows adoption and creates blind spots. Open standards for agent identity, delegation, and credential management will be crucial. So will collaboration across vendors, researchers, and regulators. We have an opportunity to build a robust foundation before agentic AI becomes ubiquitous. Let’s not waste it.

Finally, remember that identity is not just a technical problem; it’s a cultural one. Security teams, developers, and business leaders must work together. Training is essential. Adapting policies and processes to reflect the realities of autonomous software will take time. But the benefits—faster workflows, deeper insights, and the ability to delegate routine tasks to machines—are worth the investment.

Conclusion

Human-centric IAM has served us well for decades, but it is ill-equipped for a future dominated by AI agents. A new identity control plane, built around dynamic identities and purpose-bound access, is essential to govern agentic AI responsibly. Coupled with an identity security fabric that unifies governance across humans and machines, this control plane will enable organizations to embrace autonomy without compromising security or compliance.The journey begins with awareness: understand your machine identities, separate agents from generic service accounts, and start experimenting with short-lived credentials. From there, build the monitoring, policies, and human oversight needed to keep agents honest. Engage with standards groups to help shape the protocols that will define agentic identity. And above all, treat AI agents not as black boxes but as members of your digital workforce. Only then can we unlock their true potential—safely, ethically, and efficiently.
