What is Identity Governance and Administration (IGA)?

Identity Governance and Administration (IGA) is a framework for managing digital identities, access rights, and compliance controls across an organization. It helps businesses decide who should have access to what, approve or remove that access, and prove that access decisions follow policy.

IGA sits at the center of identity security because most breaches and compliance failures involve excessive, outdated, or poorly reviewed access. Instead of treating access as a one-time IT request, IGA turns it into a governed lifecycle.

How Identity Governance and Administration (IGA) works

IGA combines identity data, access policies, approval workflows, and audit records. When an employee joins, changes roles, or leaves, IGA helps trigger the right access changes automatically or through controlled approval.

For example, a finance manager may need access to payroll systems, reporting tools, and shared financial documents. IGA checks whether that access matches the person’s role, routes exceptions for approval, and records the decision for future audits.

Common IGA capabilities include:

• User provisioning and deprovisioning
• Role-based access control and access policy enforcement
• Access request and approval workflows
• Periodic access reviews and certifications
• Segregation of duties checks
• Audit reporting for compliance teams

IGA vs IAM: what is the difference?

Identity and Access Management (IAM) focuses on authentication and access enforcement, while IGA focuses on governance, visibility, and lifecycle control. They work best together.

In simple terms, IAM asks, “Can this person log in?” IGA asks, “Should this person still have this access, and can we prove why?”

Why IGA matters for businesses

Without IGA, access can spread quietly across apps, endpoints, cloud services, and shared resources. Employees may keep permissions after changing roles. Contractors may retain access after projects end. Privileged accounts may go unreviewed.

IGA reduces these risks by making access accountable. It helps security and IT teams enforce least privilege, remove orphaned access, detect risky permission combinations, and prepare for audits with clearer evidence.

For organizations managing distributed devices and users, Hexnode can support broader identity and access control efforts by helping enforce device compliance, access policies, and secure endpoint posture alongside identity governance practices.

What makes a strong IGA strategy?

A strong IGA strategy starts with accurate identity data and clear ownership. Every user, role, application, and access decision should have a responsible owner.

It also requires regular reviews. Access that was correct six months ago may no longer be appropriate today. Automated workflows help, but human accountability remains essential for exceptions, privileged access, and sensitive systems.
