IAM decides who should have access to which resources; ITDR looks for identity misuse after access is granted and helps security teams investigate and respond. A successful login is not proof that the person, session, service account, or token behind it is safe. IAM and ITDR therefore address different stages of the same security problem: IAM establishes and enforces access, while ITDR helps spot and contain attacks that use apparently valid identities.
What IAM and ITDR each do
Identity and access management (IAM) governs identity hygiene, authentication, access policy, and privileges. It helps an organization decide who—or what—should be able to reach a system, and under which conditions.

Identity threat detection and response (ITDR) monitors identity-related activity for signs of active attack, then supports investigation and response. A useful shorthand, rather than a formal standard definition, is: IAM asks, “Who should have access to what?” ITDR asks, “What is that identity doing right now?”

| Capability | Primary question | Security role |
|---|---|---|
| IAM | Should this identity have access to this resource? | Establishes and enforces identity, authentication, policy, and privilege controls. |
| ITDR | Does this identity’s activity look like misuse or an attack? | Detects suspicious behavior and supports investigation and containment. |
The two are complementary, not alternatives. IAM remains foundational; ITDR adds visibility and response when preventive controls are bypassed, misconfigured, or abused.

Why a valid login can still be dangerous
Authentication establishes that credentials or a session met the system’s checks. It does not establish that the current activity is benign. An attacker with a stolen password, compromised session, abused token, or control of a service account may act through access that appears legitimate.
That is the gap ITDR is intended to address. Instead of treating successful authentication as the end of the security decision, teams assess what the identity does next, what it can reach, and whether related activity elsewhere supports or contradicts the apparent legitimacy of the session.
What suspicious identity activity can look like
A single anomaly is a signal to investigate, not automatic proof of compromise. Context—such as the identity’s normal behavior, assigned privileges, and activity on connected systems—helps determine whether it is meaningful.

- Changed service-account behavior: a non-human account begins accessing unfamiliar systems or performing actions outside its established role.
- Unusual privileged access: an administrator or other privileged identity reaches resources it does not normally use.
- Lateral movement: an identity accesses additional systems in a pattern that may indicate an attempt to expand an attack.
- Suspicious token or permission use: a token or granted permission is used in an unexpected way, including activity that may continue without a fresh password prompt.
These signals become more useful when linked to endpoint, network, cloud, and SaaS activity. A compromised identity can be used to move beyond the identity provider into applications, infrastructure, and sensitive data; an identity-only alert may miss that wider path.
How a SOC can connect detection to response
A practical workflow moves from an identity anomaly to evidence and a proportionate action. The exact response should follow the organization’s incident procedures and account for the risk of disrupting legitimate work.
- Detect: identify an anomalous login, permission use, service-account change, privileged action, or other identity behavior.
- Enrich: connect the identity event with relevant endpoint, network, cloud, and SaaS activity rather than evaluating it in isolation.
- Assess: establish the identity’s privileges, normal activity, affected resources, and whether the observed behavior could be authorized.
- Investigate: determine whether the combined evidence supports misuse, and establish the scope and likely impact.
- Contain: take an appropriate action under incident-response policy, such as disabling an account or revoking sessions when warranted.
Stellar Cyber describes its Microsoft Entra ID integration as enriching events with identity information and supporting actions including disabling a user, confirming compromise, and revoking sign-in sessions. Those are vendor-described capabilities, not an independent assessment of effectiveness. The broader operational point is that identity context should be available to SOC investigation and threat hunting, not confined to an IAM console.

Human and non-human identities both matter
ITDR may cover more than employee and administrator accounts. Service accounts, machine identities, OAuth applications, API tokens, and AI agents can all hold or use access. Their behavior can be consequential even when no person is signing in interactively.
Coverage varies by product. Mitiga says its ITDR offering includes employees, administrators, service accounts, machine identities, OAuth apps, API tokens, AI agents, copilots, and SaaS platform identities. It also describes behavioral baselining and correlation across identity, cloud, SaaS, and AI activity. These are the vendor’s stated capabilities, not independently verified coverage or performance findings. Before relying on a tool, check which identity types it actually monitors in your environment.
What vendor examples do—and do not—establish
Stellar Cyber’s article describes features in version 6.6 for Impossible Travel and User Login Location anomaly detections: customizable suppression, improved username prioritization, and ASN enrichment for Impossible Travel. The article says the expected delay for Impossible Travel detection is 5–10 minutes after on-time data ingestion, and warns that ingestion delays can extend the interval. This is a vendor-stated, ingestion-dependent timing detail, not a guaranteed end-to-end detection SLA or an independently verified benchmark.
The same article names Active Directory, Microsoft Entra ID, and Okta as identity telemetry sources that can be correlated with endpoint, network, cloud, and other security signals in Stellar Cyber’s SecOps platform. That describes the vendor’s integrated-SOC approach; it does not establish comparative performance against other products.
Mitiga’s product page describes ITDR as detecting and responding to active identity-based attacks, including impossible travel and token misuse. Its descriptions, like Stellar Cyber’s, should be read as vendor claims rather than independent evaluations.
How to evaluate ITDR alongside IAM
When assessing whether an ITDR capability complements existing IAM and SOC tools, focus on operational fit rather than the label alone. Ask vendors and internal teams to demonstrate the following against your actual identity and telemetry environment:
Best Value
- Identity coverage: Which human and non-human identities are monitored, including service accounts, machine identities, applications, tokens, and agents?
- Telemetry coverage: Can the system use relevant identity-provider, cloud, endpoint, network, and SaaS signals?
- Correlation: Does it connect related events into an incident, or leave analysts with isolated alerts to assemble?
- Detection timing: What are the start and end points for any latency figure? Does the clock begin at event generation, ingestion, or another stage, and how do delays affect it?
- Response controls: Which actions are available, and can they be subject to approval or other safeguards?
- Investigation support: What event history and context are retained, and can analysts reconstruct what the identity accessed?
- SOC compatibility: Does the capability fit the organization’s existing alerting, case management, and response processes?
These checks help distinguish a useful identity signal from a complete detection-and-response workflow. They also expose where IAM policy, telemetry, or response ownership needs improvement rather than assuming that deploying ITDR alone closes every gap.
Why identity security is drawing more attention
Stellar Cyber’s August 2026 article attributes several statistics and forecasts to Gartner: more than 50% of surveyed organizations had experienced at least one cybersecurity incident involving compromised machine identities; collaboration between IAM and cybersecurity functions was associated with a 30% improvement in achieving IAM goals in Gartner’s 2024 IAM Leadership Survey; and Gartner forecasts, as reported in the article, that AI agents could halve the time needed to exploit exposed accounts by 2027 and that 70% of CISOs would use identity visibility and intelligence capabilities by 2028. The article also says credential misuse was the leading breach cause cited from the 2025 Verizon DBIR, without giving a percentage.
These figures are attributed through Stellar Cyber’s article; they should not be treated as independently verified here. In particular, the 2027 and 2028 values are forecasts, not observed outcomes. The practical implication does not depend on treating a forecast as a guarantee: identities—including non-human ones—are an important part of the attack surface, and access controls need monitoring and response around them.
