Why Your Microsoft 365 Tenant Shows Risky Users Every Day

Key Takeaway

One of the most common concerns raised by Microsoft 365 administrators is opening Microsoft Entra and discovering users continually appearing in the Risky Users report. The natural assumption is that attackers are actively compromising accounts across the organization.

In reality, many risky user detections are generated by legitimate business activity, exposed credentials, VPN usage, travel, mobile devices, authentication anomalies, and numerous other factors that Microsoft continuously evaluates behind the scenes.

A risky user does not automatically mean a compromised user. It means Microsoft has observed signals that suggest the account deserves additional scrutiny.

What Is A Risky User?

Microsoft Entra Identity Protection identifies a user as risky when evidence suggests the account may have been compromised. These signals can originate from leaked credentials, malicious infrastructure, atypical authentication behavior, threat intelligence feeds, sign-in risk events, or unusual account activity patterns.

This differs from sign-in risk. Sign-in risk evaluates a specific authentication attempt. User risk evaluates the likelihood that the identity itself may no longer be fully controlled by the legitimate user.

Think of it this way: sign-in risk asks whether the login is suspicious, while user risk asks whether the account itself should be trusted.

Why Do Microsoft 365 Tenants Show Risky Users Every Day?

Many organizations assume risky user detections indicate a problem unique to their environment. In reality, risky user detections have become increasingly common because cloud identity platforms evaluate far more signals than traditional on-premises systems ever could.

Microsoft continuously analyzes authentication activity, location data, IP reputation, credential exposure information, behavioral patterns, threat intelligence, application access, device data, and sign-in history. As a result, the platform can detect activity that previously would have gone unnoticed.

In many organizations, risky users appear regularly because users are constantly interacting with cloud services from different devices, locations, applications, and networks.

Why Licensing Can Change What You See

One of the most misunderstood aspects of Microsoft Entra Identity Protection is that licensing can affect how much information administrators actually receive about a risky user or risky sign-in event.

Many administrators assume Microsoft is not providing details because the platform lacks information. In reality, Microsoft may have identified a specific risk detection but the tenant’s licensing level may limit visibility into the detection itself.

This often creates confusion because one tenant may see a highly detailed detection such as Password Spray, Impossible Travel, Malicious IP Address Activity, or New Country Detection while another tenant sees only a generic risk notification.

Two administrators may be looking at the same type of risky activity but see completely different levels of detail based on licensing.

This is one reason organizations frequently underestimate identity risk. The signals may exist, but the information needed to understand exactly what Microsoft detected may not be visible.

Leaked Credentials Often Trigger Risky User Detections

One of the most common causes of risky users is credential exposure. Microsoft continuously evaluates multiple intelligence sources and can identify situations where credentials may have been exposed through breaches, password dumps, credential theft campaigns, or other external compromise events.

Importantly, a leaked credential does not automatically mean an attacker accessed the environment. However, it does indicate that valid authentication information may already be known to someone outside the organization.

Because leaked credentials can be tested months or years after exposure, organizations should take these detections seriously even if no successful compromise has yet been identified.

The safest assumption is that exposed credentials will eventually be tested by an attacker somewhere.

VPN And Proxy Activity Can Look Suspicious

VPNs and proxy services change how user traffic appears on the internet. While they often enhance privacy and security, they can also create authentication patterns that appear unusual to Microsoft’s risk engines.

Users may appear to authenticate from locations that differ dramatically from their normal sign-in patterns, especially when VPN providers route traffic through cloud infrastructure in other regions or countries.

This is why VPN activity sometimes contributes to risky user or risky sign-in detections even when the underlying activity is completely legitimate.

Business Travel Frequently Creates Risk Signals

Traveling users often generate authentication activity from airports, hotels, conference centers, customer locations, and unfamiliar networks. From Microsoft’s perspective, these changes can represent significant departures from established behavior patterns.

A user who normally signs in from Michigan may suddenly authenticate from California, Germany, Florida, or another location. Depending on timing and related context, these events may influence risk calculations.

Organizations that support remote and traveling workforces should incorporate travel validation into their identity investigation processes.

Mobile Devices And Carrier Networks Add Complexity

Mobile devices continuously transition between cellular providers, wireless access points, internet connections, and roaming networks. This creates significant variability in how authentication traffic appears.

Administrators are often surprised to learn that mobile carrier routing can occasionally make a user appear to sign in from locations that do not align perfectly with their physical location.

Device behavior, connectivity patterns, and network architecture all contribute to how Microsoft evaluates authentication risk.

Shared Accounts Often Generate Risk Signals

Shared accounts remain one of the most common causes of confusing identity protection results. When multiple people use the same credentials, authentication patterns become difficult to evaluate accurately.

Sign-ins may originate from different devices, offices, networks, and geographic regions within short periods of time. This creates behavior that naturally appears unusual.

Beyond the security implications, shared accounts reduce accountability and make investigations substantially more difficult.

Why Context Matters More Than The Alert

One of the biggest mistakes organizations make is assuming every risky user detection represents a security incident. Alerts are signals, not conclusions.

User role, device status, authentication method, business purpose, travel status, application access history, privileges, and recent activity all contribute critical context that should influence investigative decisions.

Effective identity security is not about blindly reacting to alerts. It is about understanding what Microsoft is telling you and applying that information within the broader context of the business.

Risk Doesn’t Always Mean Compromise

One of the most important concepts administrators must understand is that risk and compromise are not the same thing. Microsoft Entra Identity Protection surfaces signals that indicate suspicious activity, but a risk detection is rarely enough information by itself to prove an account has been compromised.

This distinction matters because organizations that overreact to every alert often create unnecessary disruption, while organizations that ignore every alert miss opportunities to identify genuine threats.

Effective identity security requires a balanced approach that combines Microsoft’s signals with human validation, business context, governance processes, and investigative discipline.

Risk should trigger investigation. Investigation determines whether compromise actually occurred.

Common Risk Signals Organizations Encounter

Risky users are typically generated when Microsoft identifies one or more indicators that warrant additional review. Some of these signals are stronger than others, but all provide useful context during an investigation.

The significance of these signals varies depending on the user, the account’s privileges, the resources accessed, and what other information is available during the investigation.

Identity Risk Is Also An Operational Maturity Issue

Many organizations have access to Microsoft Entra Identity Protection capabilities but never operationalize them. The result is a tenant filled with alerts that nobody understands, reviews, or responds to consistently.

A mature Microsoft 365 security program does not simply collect risk detections. It establishes ownership, investigation procedures, escalation criteria, documentation standards, and response workflows.

Organizations often discover that their largest identity security gap is not technology. It is the lack of a repeatable operating model for handling identity-related events.

Common Investigation Mistakes

Many organizations struggle with identity protection not because Microsoft lacks information, but because investigations frequently focus on the wrong signals or reach conclusions too quickly.

These mistakes often lead to either excessive remediation activity or insufficient response when legitimate compromise occurs.

Recommended Investigation Process

Organizations should establish a repeatable methodology for reviewing risky users. A structured process reduces confusion, improves consistency, and helps support audit and compliance requirements.

Investigation consistency is often more important than investigation speed. Organizations should be able to explain why a detection was dismissed, escalated, or remediated.

Closing Thoughts

Seeing risky users every day in Microsoft Entra does not automatically mean your organization is under constant attack. More often, it reflects the reality that Microsoft continuously evaluates enormous amounts of authentication and identity data that traditional systems never monitored.

The most successful organizations understand that risky users are not simply alerts to clear. They are opportunities to validate identity behavior, strengthen security processes, improve Conditional Access policies, and better understand how Microsoft is evaluating risk within the tenant.
