What is Identity Governance and Administration (IGA)?

An employee leaves your organization on a Friday. By Monday, their accounts are technically inactive, but the access they accumulated over three years (to financial systems, patient records, cloud infrastructure) still exists in the background. Nobody reviewed or removed it. And if someone with the right credentials decided to use it, there would be no audit trail to catch it.

According to the IDSA's 2025 Trends in Securing Digital Identities report, 86% of organizations reported at least one identity-related incident in the past year. In most cases, the root cause was access that should not have existed in the first place. 

Identity governance and administration (IGA) is the framework organizations use to define who has access to what, ensure that access stays appropriate as roles change, and produce a defensible audit trail showing how every access decision was made. It covers the full identity lifecycle, from the moment someone joins an organization to the moment they leave, and every role change, system addition, and entitlement request in between. 

This post covers what IGA means, how it differs from IAM, what a working program looks like, and where traditional IGA assumptions break down in operational environments.

IAM vs. IGA: What’s the Difference?

Identity and access management (IAM) manages identities and access to resources, including authentication, authorization, single sign-on,  multi-factor authentication, and access enforcement at runtime. It answers the question "can this person get in?" IGA answers a different question: "should they have this access at all?"

The gap between those two questions is where most organizations carry their real exposure. IAM can enforce a policy, but it cannot tell you whether the policy was correct, whether the access was still needed, or whether someone accumulated permissions over time that no single reviewer ever formally approved.

As organizations scale, that gap compounds. More applications, more users, more contractors, more role changes. Without governance, what begins as a sensible access structure drifts into a state where people hold far more access than their job requires, former employees retain credentials that were never deprovisioned, and compliance audits become guesswork.

Identity governance defines and reviews the policies, roles, and access decisions that IAM systems help enforce.

The Two Functions Inside Every IGA Program

IGA brings together two closely related functions: identity governance and identity administration:

Identity Governance: Oversight and Control

Identity governance is the policy and visibility layer. It answers whether access is appropriate, compliant, and consistent with organizational risk tolerance. Core functions include:

• Access certifications and periodic reviews
• Segregation of duties (SoD) policies that identify and prevent conflicting access  combinations
• Role-based access policies that define what each job function should have
• Risk-based access analysis and anomaly detection 
• Compliance reporting for HIPAA, SOX, GDPR, and PCI DSS

Identity Administration: Operations and Execution

Identity administration is the execution layer. It handles the day-to-day mechanics of keeping access aligned with governance policy. Core functions include:

• Automated provisioning and deprovisioning
• Self-service access request workflows with defined approval chains
• Entitlement management across applications and directories
• Joiner-mover-leaver (JML) process automation
• Integration with HR systems, directories, and cloud platforms

Together, governance defines what should exist. Administration makes it happen and keeps it current.

Where IAM Stops Working, and IGA Takes Over

The practical distinction is accountability over time. IAM enforces authentication and access policies at runtime, while IGA provides the governance processes needed to define, review, and manage access throughout the identity lifecycle. Specific scenarios where IAM alone falls short:

Privilege creep: When a user changes roles, previous access is rarely fully revoked. Over time, permissions accumulate across multiple roles. IAM enforces whatever entitlements exist. IGA reviews whether they are still justified.

Orphaned accounts: Former employees or contractors whose accounts were never fully deprovisioned. IAM cannot catch what it was never told to remove. IGA can help surface these accounts through access reviews, lifecycle processes, and other governance controls.

SoD violations: A user who can both approve and process a payment creates a conflict of interest that IAM does not inherently detect. IGA can define and enforce SoD rules, flagging conflicting access before it creates unnecessary risk or becomes an audit finding.

Compliance evidence: Auditors want documented proof that access was reviewed, decisions were recorded, and inappropriate access was remediated. IGA generates that trail. IAM does not.

What a Working IGA Program Covers

Access Requests and Lifecycle Management

A functional IGA program gives users a structured way to request access and gives approvers a defined workflow to review it. Automated provisioning connects the approval to the actual system. The same automation handles deprovisioning when someone leaves or changes roles, closing the gaps that manual offboarding consistently leaves open.

Access Reviews and Certifications

Periodic access reviews confirm that existing access is still appropriate. Managers or data owners review entitlements and approve or revoke each item. Done well, reviews are risk-prioritized and produce actionable output. Done poorly, they become checkbox exercises. Modern IGA platforms use AI-assisted recommendations to surface likely decisions and flag anomalies, reducing reviewer fatigue while improving outcomes.

Segregation of Duties (SoD)

SoD rules prevent any single user from holding combinations of access that create fraud or error risk. IGA can enforce these rules during access requests, helping organizations identify or block conflicting entitlements before they are granted, while also evaluating existing access for violations. This is particularly important in finance, healthcare, and any environment governed by SOX or PCI DSS.

Audit Reporting and Compliance

IGA maintains a documented record of every access request, approval, review, and change. For organizations under HIPAA, this demonstrates that patient data access is controlled and reviewed. For SOX, it shows financial system access reflects current roles and that SoD controls are enforced. The compliance value is not just the controls themselves but the continuous documentation proving they work.

Where Traditional IGA Falls Short: Shared Devices and Frontline Workers 

Many identity and access architectures are designed around a one-person-one-account and, often, one-person-one-device model. That model works well in many corporate environments, but it becomes more difficult to apply on operational floors where multiple workers share the same terminals across shifts.

In healthcare, manufacturing, and retail, workers frequently share terminals across shifts. A hospital workstation might be accessed by dozens of nurses and technicians in a single day. A distribution center kiosk serves an entire rotating crew. In these environments, the foundational IGA question, "who has access to what," becomes genuinely difficult to answer when sessions are not consistently tied to verified individual identities.

When multiple workers share a credential or session, access governance loses its precision. Access certifications can confirm that a shared account has the right permissions, but they cannot provide the same level of individual accountability when multiple workers use that account or session. The audit trail may show the shared identity rather than the individual who performed the action.

Solving this requires identity architecture that is built for shared-device environments from the start, where every session maps to a verified individual regardless of how many people use the same device across a shift. OLOID is built specifically for this operating model, providing passwordless authentication designed for frontline workers and shared workstation environments, so that IGA programs can function as intended even where standard tooling assumptions do not apply.

How to Build an IGA Program Without Overbuilding It

IGA implementations can become difficult to manage when organizations try to govern everything at once. A scoped, phased approach works better. 

Start with discovery: Build a complete inventory of identities, entitlements, and access across all systems. Identity governance built on partial visibility is governance in name only.

Define your high-risk scope first: Prioritize applications and data that carry the most regulatory and business risk: financial systems, patient records, infrastructure. Get governance working there before expanding.

Establish a JML process: Automate joiner, mover, and leaver workflows so that access changes are triggered by HR events, not manual tickets. This helps reduce one of the major sources of orphaned access.

Run your first certification campaign: Even a limited, targeted review will surface violations and stale accounts that have accumulated undetected.

Add SoD policies incrementally: Define the most critical conflict rules first and enforce them at the point of request. Expand as the program matures.

IGA is a continuous control, not a one-time project.

The Access Risk That Outlasts Any Single Audit

Identity governance and administration gives organizations a structured way to decide who should have access, review whether that access remains appropriate, and maintain evidence of those decisions over time. But governance is only as strong as the identity information behind it.

For healthcare, manufacturing, logistics, and retail organizations with shared devices and rotating shifts, that means connecting access to the individual worker, not simply to the terminal or shared account. When every session can be tied to a verified identity, organizations can extend the accountability of their IGA program into the operational environments where traditional identity models are hardest to apply.

FAQs

1. What is the difference between IGA and IAM?

IAM manages and enforces access to applications and resources, including authentication, authorization, SSO, and MFA. IGA focuses on governing that access throughout the identity lifecycle, including access requests, approvals, certifications, segregation of duties, and compliance reporting. IAM helps enforce access; IGA helps organizations determine whether that access is appropriate.

2. What is Identity Governance, and what does it do?

Identity governance defines and manages the policies and processes used to determine who should have access to which resources. It includes access reviews, segregation of duties, access request policies, risk analysis, and compliance reporting, helping organizations keep access appropriate as roles and responsibilities change.

3. Is IGA only relevant for large enterprises?

No. Any organization subject to regulatory compliance requirements, such as HIPAA, SOX, GDPR, or PCI DSS, needs some form of identity governance regardless of size. Smaller organizations may start with a narrower scope, but the core need to know who has access to what and ensure it is appropriate applies at any scale.

4. How does IGA support compliance with HIPAA, SOX, and GDPR?

IGA can support compliance by enforcing access policies, automating periodic access reviews, and maintaining audit-ready records of access decisions and remediation. For HIPAA, this can help organizations govern access to systems containing protected health information. For SOX, IGA can support access and segregation-of-duties controls around financial systems. For GDPR, it can support appropriate access controls and help demonstrate that access to personal data is governed and reviewed.

5. What is privilege creep and how does IGA prevent it?

Privilege creep occurs when users accumulate access over time, particularly as they change roles, without prior entitlements being revoked. IGA prevents it through automated deprovisioning tied to HR lifecycle events and through regular access certification campaigns that require managers to review and confirm that each entitlement is still justified.

6. Is IGA the same as IAM?

No. IAM and IGA are related but serve different purposes. IAM manages identities and enforces access to applications and resources, while IGA focuses on governing who should have access, why they have it, whether it remains appropriate, and how those decisions are documented. Together, they help organizations manage access throughout the identity lifecycle.
