Why Your Biggest Identity Security Risk Might Be Your Strategy (and How to Fix It)

Security teams have spent years strengthening identity security through multi-factor authentication, smarter provisioning, and carefully crafted role structures. However, as organizations become more complex and users more dynamic, the concept of identity itself has begun to shift.

Identity isn’t merely a login. It’s not just a role or a collection of privileges. Identity encompasses behavior; it reflects intent. It’s about what individuals do once they’re inside: the actions they take, the data they interact with, and the patterns they follow or abandon.

Most identity security strategies are designed to manage access at entry points, and many do this effectively. However, the greater risk often arises later, after access has been granted. Someone may change roles but retain previous privileges. A third-party contractor might keep system access long after their engagement has ended. A dormant admin account could suddenly exhibit unfamiliar activity. These aren’t edge cases anymore; they’re everyday realities.

The IAM tools we rely on effectively serve their purpose: managing identities, enforcing policies, and verifying credentials. However, the challenge lies in the fact that the environment surrounding those identities has evolved. Cloud applications, shadow IT, and remote workforces have introduced new layers of complexity. What we need now is not a replacement, but a broader perspective on identity security, one that considers movement, behavior, and context.

In this article, we explore the hidden dimensions of identity security—those aspects that exist beyond authentication—and discuss how security teams can begin to protect what truly matters: the actions of identities, not just their attributes.

What Looks Safe Isn’t Always Secure

In most organizations, identity security is built on a structured framework: directories, entitlements, and roles. These systems are logical, hierarchical, and,  for the most part, reliable. They provide information about a person’s identity (at least on paper) and specify what they’re authorized to access. This model forms the backbone of IAM and has effectively served enterprises for decades.

But what’s on paper doesn’t always reflect what is occurring in reality.

Today’s workforce is dynamic. Employees move between departments, adopt cross-functional roles, or transition into new responsibilities without their access being updated accordingly. Entitlements accumulate, and outdated permissions persist. A single user may have multiple roles that no longer align with their actual day-to-day work.

And it’s not just human users; service accounts, automation bots, and third-party integrations also now operate with identities. They are often granted broad access, monitored loosely (if at all), and rarely reassessed unless something goes wrong.

This creates a form of identity security drift: a gradual divergence between the purpose for which an identity was established and its current actions. On the surface, everything appears fine. Access is legitimate, and permissions are in place. However, beneath the surface, that identity may be quietly accumulating risk.

What’s missing is a way to discern the difference between “can access” and “is accessing,”  and whether that activity is normal. Traditional IAM tools aren’t designed to pose that question. They provide answers to “who has access to what,” but not “what are they doing with it,” and certainly not “does that behavior align with expectations?”

And that’s where the cracks start to appear.

Understanding Identity Behavior, Context, and Intent

If identity is not just a set of permissions or a directory entry, then what is it?

It’s behavior.
It’s context.
It’s intent.

Identity, in practice, is defined by what someone does over time:  the systems they use, the frequency of their logins, the data they interact with, and how this changes based on the time of day, location, device, or role. It represents a dynamic profile that evolves with every click, query, and connection.

You can think of it this way: a key card tells you someone has entered the building. However, it doesn’t specify which rooms they visited, how long they stayed, or whether they started rummaging through file cabinets instead of going to their desk.

Behavioral patterns—not just access rights—ultimately define risk. For example, someone using admin privileges to update employee records is one thing. However, that same identity accessing finance systems at 3 a.m. from an unmanaged device? That presents a different scenario altogether.

This behavioral layer is where intent begins to reveal itself. It’s not always about detecting malice; sometimes it involves identifying misalignment. A well-meaning employee accesses systems they no longer need. A former contractor’s service account continues executing tasks weeks after their offboarding. These scenarios don’t always trigger alerts in traditional tools because, technically, the access is valid.

However, just because access is permitted doesn’t mean it’s appropriate. When access appropriateness goes unmonitored, organizations become oblivious to early signs of compromise or internal misuse.

To understand identity today, you can’t just consider who someone is. You also need to examine how they behave and whether that behavior aligns with the context of their role, their history, and your risk tolerance.

Identity security is not about distrusting users; it’s about understanding them and ensuring your security strategy aligns with the way work actually gets done.

The Hidden Risks of Trusting Too Much, Too Fast

In most organizations, trust is established at the point of access. The system detects no issues when a user successfully logs in from a recognized device with multi-factor authentication enabled. Access is granted, and activity goes unchallenged.

However, this surface-level trust creates blind spots, not because of system flaws but because of the absence of context surrounding the activity.

Let’s look at a few scenarios:

• The Inherited Admin: A user transitions from DevOps to a product role while keeping elevated access to infrastructure tools. Months later, that old access is used, either by the user out of habit or by an attacker who has compromised their account to make unauthorized changes. On the surface, the action appears valid. In reality, it’s a backdoor.

• The Silent Service Account: An automation script created by a contractor continues to run even after the project has ended. It possesses excessive permissions, is only loosely monitored, and is quietly accessed by a threat actor who discovers its credentials in a forgotten GitHub account. No one notices because the activity aligns with historical patterns. However, the contractor is long gone.

• The Curious Insider: A finance employee working late begins to explore customer data beyond their usual responsibilities. They have not violated any access rules. Nonetheless, this deviation from their typical behavior goes unnoticed and unchallenged until a breach investigation uncovers the activity.

These are sceanrios that happen often, not out of malice, but because security tools frequently confuse authentication with legitimacy.

When identity security is treated as a static trust anchor rather than a dynamic risk signal, we secure what we believe people should do, rather than what they’re actually doing. This doesn’t imply that we should stop trusting our users or abandon our IAM systems. Instead, it indicates that we need improved methods to validate that trust in real-time. Is this behavior typical for this identity? Does it make sense in this context? And if not, what actions should we take?

That’s the turning point: shifting from managing identity access to monitoring identity activity. It’s also where a new layer of security comes into play. Learn more with this free guide: Getting Started with ITDR.

Rethinking Identity Security

If today’s identity security strategy focuses on who should have access, the next evolution involves understanding what people actually do once they gain that access.

This means going beyond the gates: past authentication flows, role maps, and provisioning logic, and focusing on actual activities. This approach doesn't replace your IAM foundation; instead, it adds a deeper, more precise understanding of risk.

What does that look like in practice?

• Monitoring usage, not just entitlement: It’s not enough to simply know that a user can access a system. You need to understand if they do, how often, in what ways, and whether that access aligns with their role and intent.

• Identifying anomalies in context: A single login at an unusual hour isn’t inherently suspicious. However, when it is combined with access to sensitive data from an unmanaged device or lateral movement across systems, it becomes a significant signal.

• Capturing identity behavior over time: Just as a credit score develops from ongoing financial behavior, a more comprehensive picture of identity risk emerges from patterns, not snapshots.

• Flagging risks before escalation: When you notice an identity behaving unusually, you have the chance to intervene before permissions are misused, data is exfiltrated, or systems are compromised.

This shift is already underway. Security teams are realizing that the question isn’t just “Who are you?” It’s also “What are you doing?” and “Is that normal for you?” Identity security is transitioning from static trust to continuous validation. From assigning roles to understanding roles in action. From gatekeeping to ground truth.

What about the platforms that support this shift? That’s where a new category of identity-aware detection and response is emerging.

Redefining Identity Threat Detection and Response

When identity is fluid, detection needs to be dynamic too.

That’s the core insight behind Identity Threat Detection and Response (ITDR), a set of capabilities designed to detect identity-based threats through monitoring access usage, rather than simply by how it’s granted.

ITDR views identities as active participants in your environment, capable of normal or abnormal behavior and deserving of the same level of scrutiny as network traffic, endpoint behavior, or API calls.

What does ITDR actually do?

• It establishes behavioral baselines: ITDR tools monitor how identities typically behave across systems: what they access, when, and from where, thus creating a unique behavioral fingerprint for each user, service account, or integration.

• It detects important deviations: When an identity operates outside its norm, for example, a marketing user unexpectedly accessing customer PII or a dormant admin account activating from an unfamiliar location, ITDR generates a signal. Not a barrage of noise, but a context-aware alert that says, “This doesn’t look right.”

• It connects across layers of identity: ITDR links identity systems, authentication logs, cloud resources, and SaaS applications to reveal patterns that traditional tools often miss. It’s not about replacing IAM or SIEM;  it’s about enhancing them with the missing context of behavior.

• It enables real-time response: When identity misuse is detected, ITDR can initiate containment workflows that disable access, revoke sessions, and notify teams to halt threats before they spread.

In many ways, ITDR is to identity what XDR was to endpoints: a unifying layer of visibility and intelligence. It doesn’t discard what came before but builds on it, adding the behavioral lens organizations have been missing. ITDR isn’t about distrusting your systems or users; it’s about recognizing that identity is a living entity, and like anything alive, it must be observed, understood, and protected as it evolves.

Securing Identity Means Understanding Identity

You’ve undoubtedly spent years refining the methods you use to provision, authenticate, and manage access. That effort is significant, and it always will be. However, the way people work has changed. As a result, the practice of identity security also needs transformation.

If you want to truly secure identity, you need to observe it in motion; understand not only what a person can do, but also what they are doing, and whether that behavior aligns with the environment in which they operate. That’s what Identity Threat Detection and Response delivers. It bridges the gap between access control and risk visibility, allowing you to detect threats that appear legitimate on the surface but feel wrong underneath. ITDR provides you with the confidence to respond before any damage occurs.

As your organization grows, your stack expands, and your workforce evolves, consider this: Are you securing identity or simply securing logins? The difference is significant.
