An attacker with valid credentials looks exactly like a user until something watches behaviour.
Defender for Identity monitors signals from on-premises Active Directory and Microsoft Entra ID, builds behavioural profiles, and detects the reconnaissance, credential abuse and lateral movement that precede a domain compromise. It is the layer that notices somebody already inside.

Eight things Defender for Identity covers that other tools do not.
It watches identity, which nothing else in the stack does
Microsoft describes it as detecting, investigating and responding to identity-based attacks across on-premises, cloud and hybrid environments, monitoring signals from on-premises Active Directory and Microsoft Entra ID, and from other identity providers such as Okta. That breadth matters because most UAE organisations run both a directory and a cloud identity, and an attacker crosses between them without either side noticing on its own.
Reconnaissance, which is the earliest useful signal
Microsoft describes detections for suspicious discovery activity including attempts to enumerate user names, group membership, IP addresses and resources. This matters because enumeration is what an attacker does first, before anything is stolen or encrypted, and it is entirely invisible to endpoint and email tooling. Catching an attack at reconnaissance is the difference between an incident and a breach.
Credential abuse, including the quiet kind
Detections cover brute force attempts, repeated failed authentications and suspicious changes to user group membership. That last one is the interesting one, because adding an account to a privileged group is not obviously an attack, it is an ordinary administrative action, and it is only suspicious in context. Behavioural analysis is what supplies that context.
Lateral movement, and the paths before anybody uses them
It detects attempts to move laterally and expand control of sensitive identities across environments. Separately, and arguably more usefully, it analyses lateral movement paths that show how an attacker could traverse your environment. That second capability is preventive: it tells you which ordinary account is two steps from a domain administrator before anybody has exploited it.
Domain dominance, named specifically
Microsoft names the behaviours associated with full domain compromise directly: remote code execution on domain controllers, DCShadow, malicious domain controller replication and Golden Ticket activity. These are the techniques that convert a foothold into total control of the estate, and detecting them is the specific reason this product exists rather than being a feature of something else.
Non-human identities, which nobody monitors
Detection explicitly covers service accounts, synchronisation accounts and applications, not just people. This is the gap that matters most in practice, because service accounts are powerful, their passwords rarely change, nobody watches them, and an attacker using one behaves in a way no user-focused tool would question. Abnormal service account behaviour is one of the strongest signals available.
Posture assessments feeding Secure Score
Alongside detection there are identity security posture assessments surfaced through Microsoft Secure Score, identifying risky configurations and exposures. This is the preventive half and it is frequently more immediately valuable than the detections, because it tells you what is wrong today rather than waiting for somebody to exploit it.
How it deploys, which is lighter than people expect
Microsoft describes lightweight sensors running on your identity infrastructure, capturing and parsing relevant network traffic and Windows events locally, with API connectors for external identity providers and a cloud analytics service. Microsoft states that only the required signals are sent to the cloud service, minimising performance impact and avoiding complex network changes. That is a materially easier deployment than the network appliance model this replaced.
One finds the paths. The other notices somebody walking them.
We sell both and they answer different questions, so it is worth being clear about which one your situation actually calls for before spending on either.
- An Active Directory security audit is a point-in-time assessment. It resolves privileged group membership, finds delegations nobody can justify, identifies service accounts with standing administrative rights, and maps the routes by which an ordinary account could become a domain administrator. It tells you what is wrong right now, and the output is a remediation list.
- Defender for Identity is continuous detection. It builds behavioural profiles for users, devices and accounts and alerts when something deviates in a way that matches an identity attack pattern. It tells you that somebody is currently doing something they should not, and the output is an incident.
- The sequence that works is audit first, then detection. Closing obvious privilege paths reduces the number of ways in, which both lowers the risk and reduces the noise a detection product has to work through. Deploying detection over an unaudited directory produces alerts about a structure that should have been fixed, which is a slower and more expensive way to reach the same place.
- The exception is when you have reason to think something is happening now, in which case detection comes first and the audit follows. If a credential was phished, an account behaved oddly, or a peer in your sector was compromised, the immediate question is whether anybody is currently moving through your environment, and that is what this product answers.
Four things that decide whether this is worth deploying.
We audit the directory before recommending detection
Deploying identity detection over an unaudited Active Directory produces alerts about a structure that should have been corrected first. Resolving privileged group membership, removing standing service account rights and closing obvious escalation paths reduces both the actual risk and the volume of things the detection has to reason about. The exception is where something appears to be happening now, in which case detection comes first.
We start with the posture assessments, not the detections
The identity security posture assessments and lateral movement path analysis tell you what is wrong today, and they are frequently more immediately useful than the alerting. An organisation that acts on those findings is measurably harder to move through, and it gets that benefit whether or not an attack ever occurs, which is not true of detection alone.
We inventory service accounts before the baseline is learned
Non-human identities are where this product finds the things nothing else would, and its detections depend on knowing what normal looks like. Going in with a documented list of service accounts, what each does and what it should legitimately touch makes the early alerts interpretable rather than confusing, and it produces a useful artefact regardless.
We settle the response question before deployment
Lateral movement and domain dominance detections are urgent by nature and do not arrive during office hours. Before deploying we agree who is notified, how quickly, who can disable an account, and whether that needs a managed arrangement outside working hours. Detection with no responder is an expensive way to produce a record of an incident you did not prevent.
Six UAE situations where identity detection earns its place.
A long-lived Active Directory nobody has reviewed
Ten years of accumulated groups, delegations and service accounts, with privilege paths nobody mapped. This is where lateral movement path analysis produces the most striking output, because it shows concretely which ordinary account is a short hop from domain control. Our usual recommendation here is the directory audit first and detection immediately after, because both findings reinforce each other.
A regulated firm expected to detect and investigate
Where a regulator, an insurer or a client expects you to demonstrate detection capability across identity rather than just endpoint, this is the product that answers it, and the posture assessments produce evidence as a by-product. For firms under Central Bank requirements, the privileged access expectations map onto exactly what this monitors.
Manufacturing, logistics or any long-lived estate
Older systems, machines that cannot be patched on a normal cadence, and shared or service accounts that exist for genuine operational reasons and cannot simply be removed. Where you cannot fix the structural weakness, detecting its abuse is the next best control, and this is one of the few situations where detection genuinely substitutes for prevention.
A hybrid estate synchronising to Microsoft Entra ID
Which is most UAE organisations of any size. The synchronisation server is one of the most privileged machines you own and the sync account is powerful, so a compromise on-premises frequently becomes a compromise of the cloud tenant. Monitoring identity signals across both sides is the point, and assessing either in isolation gives a false picture.
After a credential compromise or a near miss
Somebody was phished, an account behaved oddly, or a peer in your sector was hit. Here the immediate question is whether anybody is currently moving through your environment, and that reverses the usual order: deploy detection first and audit afterwards. It is also the moment when the budget conversation is easiest, because the risk has just stopped being theoretical.
An organisation with more service accounts than it can list
A recognisable state. Applications, integrations, scheduled tasks and scripts, each with an account, most with passwords that have not changed in years, none monitored. Behavioural detection covering non-human identities is aimed exactly at this, and the inventory exercise that precedes deployment is usually worth as much as the product.

Five steps, and the sensors are the easy part.
- 1
Confirm licensing and scope the identity infrastructure
Whether your current licensing includes it, which we check against your tenant rather than assuming, and what identity infrastructure is in scope: domain controllers, any AD Federation Services or Certificate Services, and whether a non-Microsoft identity provider needs an API connector.
- 2
Audit and inventory before the baseline is set
Privileged group membership fully resolved, service accounts documented with what each legitimately touches, and the obvious privilege paths closed where they can be. This reduces what the product has to reason about and makes its early findings interpretable rather than alarming.
- 3
Deploy sensors and connectors
Lightweight sensors on the identity infrastructure, capturing and parsing traffic and Windows events locally, with only required signals sent to the cloud service. API connectors where another identity provider is in play. This is genuinely light-touch and it still involves domain controllers, so it goes through a change window.
- 4
Work the posture findings while the baseline builds
Behavioural detection needs a period to learn normal, and that time is best spent acting on the posture assessments and lateral movement path analysis, which are available immediately and do not depend on learning. Most organisations get their first tangible risk reduction from this stage rather than from an alert.
- 5
Tune, then agree the response rhythm
Early alerts get reviewed together so that expected behaviour is understood rather than suppressed blindly, service account activity is explained rather than muted, and the response path is confirmed: who is told, how fast, who can disable an account, and what happens outside office hours.
What organisations ask about Defender for Identity.
Fifteen questions worth answering first.
Is this the right next step
- Have you audited the directory first?Fixing obvious privilege paths reduces both risk and alert noise.
- Do you still run on-premises Active Directory?If you are cloud-only, the value proposition differs.
- Do you synchronise identities to Microsoft Entra ID?The hybrid join is exactly what this monitors across.
- Do you have reason to think something is happening now?If so, detection comes before audit rather than after.
- Have you confirmed your licensing includes it?We check this rather than assuming, because it varies.
Deployment readiness
- How many domain controllers would need sensors?Sensors run on identity infrastructure, not on every endpoint.
- Do you also run AD Certificate Services or AD FS?Additional identity infrastructure worth including in scope.
- Do you use a non-Microsoft identity provider as well?API connectors cover systems such as Okta.
- Can you inventory your service accounts before you start?Their normal behaviour is the baseline being learned.
- Is there a change window for domain controller work?Light touch, and still domain controllers.
Would anybody act
- Who receives an identity alert, and how quickly?Detection with no responder changes nothing.
- Would somebody act on a lateral movement alert at 2am?These attacks do not respect office hours.
- Is there a process for disabling a compromised account fast?Decided in advance, not during the incident.
- Would the posture recommendations get actioned?They arrive in Secure Score and are frequently ignored.
- Do you have or need a managed response arrangement?Worth deciding before buying detection.
The pages around this one.
Active Directory security audit
The point-in-time assessment that finds the privilege paths this product would later watch somebody walk, and the recommended first step for most estates.
Defender for Endpoint
The device layer of the same family, and the plan comparison where Business Premium unexpectedly comes out ahead of E3.
Microsoft Entra
The cloud identity platform this monitors alongside on-premises Active Directory, and the controls that reduce what an attacker can reach.
Ask which of your ordinary accounts is two steps from domain admin.
That is the question lateral movement path analysis answers, and almost no organisation can answer it today. If you have never audited the directory, that is the better first move, and we will tell you so rather than deploying detection over a structure that should be fixed first.
