The digital transformation has accelerated the adoption of cloud-based solutions, intelligent automation, and hybrid environments. While this shift has improved operational agility, it has also introduced a new landscape of risks related to security and access control. That’s where Identity and Access Management (IAM) plays a critical role.
IAM is a strategic approach to protecting data, applications, and processes—especially in the face of rising shadow IT, or the use of unauthorized technologies within companies.
In this article, you’ll learn what IAM is, how it works, its key benefits, and how effective access management directly supports the mitigation of shadow IT. Keep reading!
What Is Identity and Access Management (IAM)?
Identity and Access Management (IAM) is the process of ensuring that the right users have the appropriate level of access to systems, data, and corporate resources—at the right time and under the right conditions. This applies to both human users and non-human identities, such as bots, scripts, and automated applications.
In practice, IAM combines security policies, authentication protocols, permission controls, and continuous monitoring to ensure security, compliance, and traceability.
According to Microsoft, IAM serves as the backbone of digital security, enabling companies to maintain granular control over who accesses what and why—effectively reducing the attack surface.
How Does IAM Work?
An IAM solution acts as a control layer between users (human or machine) and an organization’s resources (systems, applications, data, and infrastructure). Its core function is to ensure that only the right identities receive the right level of access at the right time—with full traceability.
To do this, IAM is built on three key pillars: Identification, Authentication, and Authorization. Here’s how each step works:
1. Identification
The first step in any IAM system is the creation of a unique digital identity for each user, device, application, or service. This identity may include attributes such as name, job title, department, location, business role, and even access context (time of day, geolocation, device type, etc.).
This identity serves as the foundation for all subsequent access and permission decisions. In modern environments, this also applies to non-human identities, such as RPA bots, APIs, and automated applications.
2. Authentication
Once an identity is established, the next step is to verify that it truly belongs to the person or system attempting access. This process is known as authentication, and it may include different methods:
-
Username and password (traditional but less secure);
-
Biometrics (fingerprint, facial recognition, voice);
-
Physical or digital tokens;
-
Multi-Factor Authentication (MFA) — combining two or more factors (something the user knows + something they have + something they are).
3. Authorization
After verifying the identity, the IAM system must determine what resources this identity can access and to what extent. This is known as authorization.
Permissions are typically assigned based on:
-
RBAC (Role-Based Access Control): access defined by job roles or functions;
-
ABAC (Attribute-Based Access Control): access based on contextual attributes;
-
Least privilege principle: granting only the minimum access required to perform a specific task.
Benefits of Implementing an IAM Strategy
In addition to reducing security risks and combating shadow IT, Identity and Access Management (IAM) brings a range of technical and operational benefits:
1. Enhanced Information Security
The primary function of IAM is to ensure that only authorized users have access to the right resources at the right time. This significantly reduces the risk of unauthorized access, data leaks, and credential-based attacks.
Moreover, granular permission controls prevent the accumulation of excessive privileges—one of the main causes of internal security breaches.
2. Easy Integration with Multiple Systems and Automations
Modern IAM solutions are designed to integrate seamlessly with ERPs, CRMs, cloud platforms, DevOps environments, and automation tools, allowing identity management to keep pace with the complexity of today’s digital ecosystems.
3. Automation of Administrative Provisioning Tasks
With IAM, processes such as account creation, permission assignment, and access revocation are no longer manual. Automating these workflows saves IT teams time and helps avoid human error and critical delays.
4. Faster Access Provisioning and Revocation
IAM removes operational bottlenecks, enabling users to gain access quickly—based on predefined rules, roles, or profiles.
Likewise, automatic access revocation during offboarding, role changes, or risk events strengthens the organization’s incident response.
Why Is IAM Important?
As environments become more distributed—with multiple devices, SaaS applications, automations, remote workers, and third-party vendors—access control becomes increasingly complex.
Without a clear IAM strategy, companies are vulnerable to:
-
Unauthorized access to sensitive data;
-
Outdated permissions (e.g., former employees with active access);
-
Data leaks through unauthorized integrations;
-
Compliance violations with regulations like LGPD and GDPR.
IAM and Shadow IT: What’s the Connection?
Shadow IT refers to the use of applications, tools, and services without the knowledge or approval of the IT department. According to Palo Alto Networks, this behavior directly impacts a company’s security posture, as many of these systems do not follow corporate protection standards.
Common examples of Shadow IT:
-
Spreadsheets saved in personal Google Drive accounts
-
Homemade bots or integrations created by business units
-
Use of unauthorized chat or automation tools
How Does IAM Help Combat Shadow IT?
-
Centralized access control: makes it easier to detect non-standard systems
-
Role-based policies: ensure users only have access to what they actually need
-
Auditing and access logs: expose unauthorized use of apps or bots
-
Integration with security tools: helps detect and block suspicious behavior
Centralized Governance Beyond IAM
By adopting a centralized governance approach, companies go beyond identity and access management (IAM). This strategy consolidates control over who does what, where, and how — across systems, automations, and operational workflows.
Centralized governance enables:
-
Reduction of Shadow IT: with clear access and control policies, it’s easier to identify and eliminate the use of unauthorized tools, scripts, and bots
-
Scalable growth with security: companies can grow fast without losing control of their tech environments
-
Regulatory compliance: strong governance ensures the organization remains aligned with regulations like LGPD, reducing legal risks
-
Cross-team collaboration: standardized permissions and workflows enable more efficient collaboration between departments without compromising security
Got the Importance of IAM?
Identity and Access Management (IAM) is now essential for any business operating in the digital space. In an environment of large-scale automation, multiple cloud platforms, and decentralized users, security depends on identity governance.
