Blind spots in identity are today’s biggest security risk. Here’s how to fix them.‍

‍

In today’s hyper-connected and threat-saturated digital landscape, one truth is rapidly becoming self-evident to defenders across every industry: identity is the new perimeter, and access is the new security. As traditional network boundaries dissolve in favor of hybrid and cloud-first infrastructures, adversaries are increasingly pivoting toward the exploitation of identities—privileged accounts, service identities, orphaned users, misconfigured roles—as the primary path to breach and move laterally within environments.

But here’s the catch: you can’t protect what you don’t know exists. This is where Identity Security Intelligence becomes not just useful but essential. And at the core of that intelligence lies a foundational capability: Identity Discovery.

‍

What is Identity Security Intelligence?

Identity Security Intelligence (ISI) is the ability to aggregate, analyze, and act on data about identities, their associated roles, privileges, behaviors, and risks across the entirety of an organization’s infrastructure—from on-premises directories to SaaS applications and multi-cloud platforms.

Think of it as the intersection between Identity and Access Management (IAM), risk analytics, and threat detection. It’s not just about managing identities; it’s about understanding them deeply—who they are, what they can do, where they exist, and how they behave over time.

‍

The Foundation: Identity Discovery

Before an organization can reason intelligently about identity risk, it must first discover all identities that exist across its environment. This includes:

• Traditional/On-Prem Identities: Users in Active Directory, service accounts in legacy apps, local admin accounts on servers, etc.
• Cloud Identities: Identities in Azure AD, AWS IAM users and roles, Google Workspace users, cloud-native service principals, API keys, containers, and ephemeral workloads.
• Shadow and Orphaned Identities: Legacy accounts no longer linked to active users, leftover access from decommissioned applications, services, and mismanaged credentials hiding in infrastructure-as-code.

A robust Identity Discovery capability surfaces all these identities, —whether they’re centralized or scattered, active or dormant, human or non-human.

‍

Why Identity Discovery is Challenging (Yet So Crucial)

The complexity arises from the fact that identity is now distributed. No longer tethered to one central directory, identities live in different silos across multiple environments and systems. Each cloud provider has its own model. Each SaaS app may define roles and entitlements differently. Each legacy system might still have its own local accounts.

This fragmented landscape creates massive blind spots:

• Privileged accounts in cloud environments that bypass central logging.
• Orphaned identities with persistent access to sensitive data.
• Service accounts with excessive, never-reviewed permissions.
• Redundant roles due to M&A, org restructuring, or tool proliferation.

Without discovery, these blind spots can easily lead to compromised credentials.

Beyond Inventory: Discovering Roles, Privileges, and Entitlements

Discovery doesn’t stop at listing accounts. To enable true security intelligence, you must also map the roles, privileges, and entitlements tied to each identity.

This means answering questions like:

• What can this identity do?
• Where can it go?
• What data can it access?
• What systems does it control?
• Are these privileges aligned with its purpose?

For example, discovering an AWS IAM user is useful. But understanding that the user has AdministratorAccess across multiple production accounts—and the account hasn’t logged in for 90 days—is critical.

Or take an identity in Microsoft 365 that has full mailbox access across HR, Finance, and Legal departments. Is that intended? Necessary? Or a remnant of an old project no one cleaned up?

Mapping these entitlements and privilege chains across your hybrid estate helps you:

• Identify toxic combinations of access.
• Enforce the principle of least privilege.
• Detect privilege escalation paths.
• Uncover misconfigurations before attackers do.

Identity Risk: The Unseen Attack Surface

The more fragmented and complex your identity environment, the greater your exposure. Attackers thrive in this chaos.

From techniques like Kerberoasting, Golden SAML, and token theft, to exploiting cloud misconfigurations and unused admin roles, modern adversaries are experts at chaining together identity weaknesses and misconfigurations.

By contrast, organizations that maintain a comprehensive view of identity risk across the board can:

• Detect anomalous behavior in context (e.g., a service account accessing finance systems for the first time).
• Shut down dormant or orphaned accounts.
• Flag privilege drift over time.
• Simulate attack paths based on current entitlements.
• Proactively remediate risk without waiting for incidents.

‍

What Makes Identity Security Intelligence Actionable?

Let’s be clear: data alone is not intelligence. Intelligence emerges when data is correlated, contextualized, and operationalized.

An effective Identity Security Intelligence program must provide:

• Continuous Discovery: Real-time or near-real-time visibility into new, removed, or changed identities.
• Entitlement Mapping: Deep visibility into fine-grained privileges across cloud and on-prem environments.
• Risk Analytics: Automated scoring based on behavior, privilege level, and exposure.
• Historical Context: Identity behavior over time—who did what, when, and whether it deviated from the norm.
• Integrations: Feeds into SIEM, SOAR, and IAM/PAM platforms for proactive and reactive response.

This turns identity data into strategic insight—fuel for critical decisions in security operations, compliance, audits, and incident response.

‍

Getting Started: Build Your Identity Intelligence Baseline

If your organization is just starting down this path, here’s a basic roadmap:

1. Inventory all identities—human, service, machine—across on-prem and cloud.
2. Map entitlements for each identity across applications, infrastructure, and data.
3. Assess privilege levels and compare against business needs and least privilege standards.
4. Identify toxic combinations—privilege escalations, cross-boundary access, unused high-risk roles.
5. Establish continuous discovery and monitoring, not just point-in-time scans.
6. Feed this intelligence into your risk models and threat detection systems.

The Bottom Line

In the same way that endpoint detection changed the game a decade ago, Identity Security Intelligence is becoming table stakes for defending against modern threats. Attackers know that identity is the weakest link in many organizations. Our job as defenders is to turn it into a strength.

By investing in identity discovery—including deep insight into roles, entitlements, and privileges—you build a clear, contextual picture of your true identity surface. Only then can you manage it, reduce it, and defend it with confidence.

In a world where credentials are more valuable than malware, identity intelligence isn’t just good hygiene—it’s your first line of defense.
