Microsoft is introducing agent identities to support autonomous and semi-autonomous systems across Microsoft Entra and Microsoft 365. These identities are not human, but they can authenticate, hold permissions, and perform actions inside production environments.
Agent identities do not appear in isolation. They are being introduced into environments already dominated by non-human identities, where service accounts, applications, and managed identities are deeply embedded. As a result, they push existing identity assumptions to their limits and are rapidly becoming a focal point for identity threat detection and response.
Before agent identities entered the conversation, identity security was already shifting away from a human centric model.
A Non Human Identity (NHI) is any identity object within Active Directory, Microsoft Entra ID, or Microsoft 365 that represents a system, service, automation, device, or AI agent rather than a person. These identities run services, execute automation, integrate applications, and operate continuously across hybrid environments.
In modern Microsoft ecosystems, non‑human identities already outnumber human users, often by orders of magnitude. Industry research consistently shows machine and service identities ranging from 20 to more than 50 non‑human identities for every human user in large enterprise environments.
Yet many of these identities operate outside standard governance and monitoring practices. This lack of oversight creates a significant gap in identity threat detection and response, as these identities frequently accumulate long lived credentials, excessive permissions, and unclear ownership, making them attractive targets for attackers and persistent blind spots for security and compliance teams.
Service accounts, managed identities, and application identities taught security teams a critical lesson:
anything that can authenticate and act must be governed like a user, even if it is not human.
Agent identities follow the same rule, but with new characteristics:
From an identity threat detection and response (ITDR) perspective, this changes the questions security teams must answer. It is no longer enough to ask who acted. Teams must also understand:
| Object | What it is | Why it matters for ITDR |
| Agent Identity Blueprint | A template that defines how agent identities are created and what permissions they are allowed to have | Permissions often originate here, making blueprints a primary source of agent risk |
| Agent Identity | A non‑human identity that authenticates and performs autonomous or semi‑autonomous actions | Appears as the acting identity in agent‑driven activity |
| Agent Identity Blueprint Principal | The tenant‑specific representation of a blueprint when it is added to an Entra tenant | Shows up in audit and change records when blueprint authority is exercised |
| Agent User | A user‑like object created when agents interact with user‑oriented systems or workflows | Can be mistaken for a human user without clear identification |
As agent identities and AI‑driven automation expand, many security teams are seeing new tools and controls emerge to address agent‑related risk, often introducing additional views or management surfaces.
This approach increases operational overhead without reducing risk.
Identity threat detection and response depends on context. Investigations require historical change data, permission lineage, and the ability to correlate activity across users, applications, and services.
Adding another dashboard fragments that context:
For agent identities, this problem is amplified. Agents do not operate in isolation. They interact with existing service principals, managed identities, groups, and roles. Treating agent risk as a separate product category creates blind spots rather than closing them.
Agent identities do not require a new security console. They require continuity with existing visibility.
Agent identities are not a new identity silo. They are an extension of the non‑human identity landscape that already exists across Active Directory, Entra ID, and Microsoft 365.
The same questions security teams already ask about service accounts and applications now apply to agents:
Answering those questions requires continuity, not separation. A fragmented approach prevents teams from achieving a unified identity threat detection and response strategy across the entire hybrid ecosystem.
Guardian 7.2 expands Change Monitoring to include Microsoft Entra agent identity entities:
This brings agent‑related identity changes into the same Change History and investigation workflows security teams already use, streamlining identity threat detection and response for users, groups, and applications.
Guardian 7.2 also introduces a Saved Query for Organizations that allows administrators to quickly isolate agent‑related activity directly in Change History.
As agent identities scale, manually hunting through mixed human and non‑human activity becomes impractical. The Saved Query provides a consistent, reusable way to surface agent activity without requiring administrators to create custom queries, separate views, or an additional investigation tool.
Because this capability is implemented as a Saved Query within Change History, administrators can reuse the same agent‑focused logic for investigations, reporting, advanced alerting, and automated response workflows.
This includes scenarios where alerts trigger automated rollback based on policy and risk tolerance, allowing agent‑initiated changes to be detected, reported, and reversed using the same identity controls already in place for human and other non‑human identities.
This keeps detection, reporting, and response for agent identities unified within existing identity operations, rather than fragmenting agent risk into a separate dashboard or control plane.
Most organizations already struggle to govern traditional non‑human identities. Agent identities raise the risk level further by introducing autonomous behavior, indirect permission assignment, and new attribution challenges.
Without visibility into agent identity changes, a robust identity threat detection and response posture is impossible to maintain for several reasons:
By extending monitoring to agent identity objects, Guardian 7.2 helps security teams treat non‑human identities as first‑class security subjects, not edge cases.
Agent identities are no longer theoretical. They are being created today and becoming part of real production environments.
Identity threat detection and response must evolve to include non‑human identities, not as an add‑on, but as a core capability.

Identity threat detection and response is a security discipline focused on protecting the credentials, permissions, and activities of all account types, not just humans. In modern environments, this includes service accounts, managed identities, and the new wave of Microsoft agent identities. Because these non-human entities often hold high-level permissions and operate autonomously, they have become a primary focus for identity threat detection and response strategies aimed at stopping lateral movement and privilege escalation.
Unlike traditional user accounts, agent identities can be automatically generated by AI platforms and receive permissions through abstracted “blueprints” rather than direct assignments. This creates a visibility gap in identity threat detection and response because it becomes harder to determine where an identity’s authority originated or who is responsible for its actions. Without specialized ITDR monitoring, these agents can change production environments without leaving a clear trail back to a human sponsor.
While IAM focuses on “who has access to what,” identity threat detection and response focuses on “what is happening with that access right now.” IAM sets the rules, but ITDR monitors for breaches of those rules in real-time. For example, an ITDR solution like Guardian 7.2 doesn’t just store a list of agent permissions; it tracks every change to those permissions, allowing security teams to detect and reverse unauthorized escalations immediately.
An Agent Identity Blueprint is a template that defines the scope and power of an AI agent before it is even created. For identity threat detection and response, the blueprint is a “critical control point.” If an attacker or a misconfigured process alters a blueprint, every agent spawned from it inherits those risks. Effective identity threat detection and response must therefore monitor the lineage of these blueprints to prevent widespread security vulnerabilities across the Microsoft Entra tenant.
The most effective way to unify identity threat detection and response is to avoid “dashboard silo” syndrome. Instead of using different tools for human users and AI agents, organizations should integrate agent monitoring into their existing change history and audit workflows. This ensures that identity threat detection and response remains consistent, allowing analysts to correlate activity across the entire ecosystem without switching between fragmented security consoles.
