Modern businesses depend on digital identities to access applications, cloud platforms, databases, collaboration tools, APIs, and other technology resources. As organizations adopt more services, the number of human and non-human identities they manage can grow rapidly. This condition, commonly known as identity sprawl, can create security gaps that are difficult to see and even harder to control.

The cybersecurity perspective associated with Lodi Palle highlights the importance of understanding how identities influence modern security. Protecting an organization is no longer limited to securing devices and networks. Organizations must also understand who—and what—is allowed to access their digital resources.

What Is Identity Sprawl?

Identity sprawl occurs when an organization accumulates a large and increasingly difficult-to-manage number of digital identities, accounts, credentials, permissions, and access relationships.

These identities can include:

• Employee accounts
• Administrator accounts
• Contractor accounts
• Customer identities
• Service accounts
• Application identities
• API credentials
• Cloud identities
• Machine identities
• AI or automated-agent identities

Identity growth is not automatically a security problem. The risk increases when organizations lose visibility into which identities exist, who owns them, what they can access, and whether they are still required.

An account created for a temporary project, for example, can become a long-term security exposure if nobody remembers to disable it.

Why Identity Sprawl Is Increasing

Several trends are contributing to the expansion of digital identities.

Cloud Adoption

Cloud environments can create identities across multiple platforms and services. Employees may use separate credentials or permissions for different applications, while automated workloads may require their own identities.

Remote and Hybrid Work

Distributed teams often need access to applications from different locations and devices. Organizations may create additional accounts and permissions to support flexible working arrangements.

SaaS Applications

Businesses increasingly depend on third-party software for communication, project management, finance, marketing, development, analytics, and other functions.

Each service can introduce additional identities and access relationships.

Automation and APIs

Modern applications communicate with each other through APIs and automated processes. These connections frequently require service accounts, tokens, keys, or other credentials.

Temporary Access

Employees, contractors, developers, and vendors may receive access for specific projects. Problems arise when temporary permissions remain active after the original requirement disappears.

How Identity Sprawl Creates Security Gaps

The biggest challenge is not simply the number of identities. It is the loss of visibility and control that can accompany identity growth.

Forgotten Accounts

Old accounts can remain active after employees leave, projects end, or contractors stop working with an organization.

Attackers may target these overlooked identities because they can provide an unexpected route into business systems.

Excessive Permissions

An identity may accumulate permissions over time.

For example, an employee may initially need access to one application but later receive additional privileges for different projects. If previous permissions are never removed, the account may eventually have far more access than necessary.

This violates the principle of least privilege and can increase the potential impact of account compromise.

Shared Credentials

Shared accounts make accountability more difficult because organizations may not be able to determine which individual performed a particular action.

Shared credentials can also make password management and access revocation more complicated.

Orphaned Service Accounts

Service accounts may continue operating even when the application, workflow, or employee who originally created them is no longer active.

Because these identities can sometimes have elevated permissions, unmanaged service accounts can become particularly important security concerns.

Identity Sprawl and the Attack Surface

Identity has become a central component of the modern attack surface.

An attacker does not necessarily need to exploit a vulnerable server if they can obtain legitimate credentials and use them to access a trusted system.

Compromised identities can potentially allow attackers to:

• Access sensitive applications
• Retrieve confidential information
• Move between systems
• Escalate privileges
• Modify configurations
• Create additional accounts
• Abuse cloud resources

This is why organizations increasingly need to treat identity security as a core part of cyber defense rather than simply an administrative IT function.

The Problem With Excessive Access

One of the most common identity-management problems is excessive access. Employees often change roles, join projects, or receive temporary permissions. Without regular reviews, their access can accumulate. This creates what is sometimes described as privilege creep. A better approach is to regularly compare access rights with actual job responsibilities.

Organizations should ask:

• Does this person still need this access?
• Is the permission appropriate for their current role?
• When was the access last used?
• Is the account still active?
• Who owns the account?
• Can the permission be reduced?

Regular access reviews can help reduce unnecessary privileges.

Identity Sprawl in Multi-Cloud Environments

Organizations using multiple cloud providers can face additional identity-management challenges. Different platforms may use different identity models, permission structures, policies, and administrative tools. Without centralized visibility, security teams may struggle to understand the complete access landscape.

A user might have low privileges in one environment but significant permissions in another. The combined risk may not be obvious when each environment is reviewed separately. Centralized identity governance and consistent access policies can help organizations establish better control.

Non-Human Identities Are Becoming More Important

Human users are only one part of the identity landscape. Applications, workloads, services, APIs, devices, and automated systems can also require identities. These non-human identities can sometimes outnumber human users by a significant margin in complex technology environments.

Managing them creates unique challenges because organizations need to understand:

• Who owns the identity?
• What does it access?
• Why does it need that access?
• How long should the credential remain valid?
• How is the credential rotated?
• What happens when the application is retired?

Organizations should include these identities in their broader identity-security strategy.

AI Agents and the Expanding Identity Landscape

The growing use of AI-powered systems introduces another dimension to identity management.

AI agents can potentially interact with applications, data, tools, and workflows on behalf of users or organizations. When such systems are granted permissions, organizations need to understand exactly what actions those identities can perform.

According to Lode Palle, this creates a need for clear authorization boundaries and monitoring. Organizations should avoid giving automated systems broad permissions simply because those permissions may be convenient. Access should be limited according to the agent’s actual responsibilities.

How Organizations Can Reduce Identity Sprawl

Reducing identity sprawl requires continuous governance rather than a one-time cleanup.

Create an Identity Inventory

Organizations should maintain visibility into human and non-human identities across important systems.

Assign Ownership

Every important account should have a clearly identified owner or responsible team.

Apply Least Privilege

Access should be limited to what is necessary for a user’s or system’s responsibilities.

Automate Joiner-Mover-Leaver Processes

When employees join, change roles, or leave, identity and access changes should occur quickly and consistently.

Conduct Regular Access Reviews

Periodic reviews can identify unused accounts, excessive permissions, and outdated access.

Remove Dormant Accounts

Unused identities should be disabled or removed according to organizational policies.

Rotate Credentials

API keys, service credentials, and other secrets should be managed and rotated appropriately.

Monitor Identity Activity

Security teams should look for unusual authentication behavior, unexpected privilege changes, and suspicious access patterns.

Identity Governance and Zero Trust

Identity sprawl also demonstrates why Zero Trust approaches emphasize continuous verification.

Trust should not be granted permanently simply because an identity was previously approved.

Organizations can evaluate factors such as:

• User identity
• Device security
• Location
• Application
• Requested resource
• Sensitivity of data
• Risk level
• Current authentication context

This approach can help organizations make access decisions based on current circumstances rather than assumptions.

Measuring Identity Security

Organizations should measure whether identity controls are actually reducing risk.

Useful metrics can include:

• Number of inactive accounts
• Number of privileged identities
• Percentage of accounts with MFA
• Number of orphaned accounts
• Unused permissions
• Time required to revoke access
• Number of service accounts without clear ownership
• Frequency of access reviews

These measurements can help security teams identify areas requiring improvement.

Why Identity Visibility Matters for Modern Cyber Defense

Identity sprawl is ultimately a visibility and governance challenge. Organizations cannot effectively protect access they cannot accurately identify or understand.

As businesses adopt cloud platforms, SaaS applications, APIs, automation, remote work technologies, and AI-powered systems, the identity landscape will continue to expand.

The cybersecurity perspective associated with Lodi Palle reinforces an important principle: modern security requires organizations to look beyond traditional network boundaries and pay close attention to identities, permissions, authentication, and access behavior.

By maintaining an accurate identity inventory, enforcing least privilege, removing unnecessary accounts, securing non-human identities, monitoring access activity, and regularly reviewing permissions, organizations can reduce the security gaps created by identity sprawl.
