What is identity governance and administration (IGA)?

IGA helps organizations comply with security regulations and mandates by controlling who has access to which resources, under what conditions and for how long.

As organizations manage thousands of human and nonhuman user accounts across multicloud and hybrid environments, tracking access becomes increasingly complex.

Each digital identity—whether representing a human user, device, application or AI agent—is a potential gateway to critical systems and sensitive data. When hackers get their hands on legitimate credentials, they can move freely through networks. Without proper governance, this sprawling ecosystem of identities becomes a massive attack surface, creating significant security risks and compliance challenges.

Identity governance and administration solutions help protect against identity-based attacks and reduce the risk of insider threats and data breaches.

IGA tools can automate user provisioning, implement access policies and conduct regular access reviews throughout the entire identity lifecycle, from onboarding through deprovisioning at offboarding. These functions give organizations more oversight over user permissions and activity, which makes it easier to detect—and stop—privilege misuse and abuse.

IGA solutions also help ensure ongoing regulatory compliance with mandates such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), Payment Card Industry Data Security Standard (PCI DSS) and the Sarbanes-Oxley (SOX) Act. IGA helps ensure that access to sensitive systems and data is correctly assigned and regularly reviewed, while generating audit trails to support both internal and external audits.

IGA and identity and access management (IAM) are related frameworks within identity security. IAM deals broadly with how users access digital resources, while IGA helps ensure that people use their access appropriately. 

IAM handles the operational aspects of identity security, such as password management, authentication, authorizing day-to-day access and managing accounts. IGA serves as the backbone of IAM practices, providing governance capabilities that including oversight, policy enforcement and compliance functions.

Think of IAM and IGA as addressing a set of complementary questions

• IAM: How do users access resources, and what can they do with those resources?
  
  
• IGA: Should users have this access, and can we prove that our controls meet compliance requirements?

As a subset of IAM, IGA is often implemented alongside other IAM tools. For example, if a financial analyst transfers to marketing, IGA makes sure that the employee’s new access privileges align with company policies. Continuous authentication—another IAM tool—verifies that the employee is taking post-login actions appropriate to their new position.

IGA solutions emerged to help organizations manage the growing complexity of enterprise IT environments, shifting cyberthreat landscapes and evolving compliance mandates.

Enterprise networks now span on-premises systems, private and public cloud providers, remote workstations and hundreds of software-as-a-service (SaaS) applications. Between AI agents, automated processes, service accounts and other entities, these networks are now home to an increasing number of nonhuman users.

This complexity makes manual identity and access governance nearly impossible, and it increases security risks.

IGA solutions help address complex IT environments by providing:

Without an IGA solution, IT staff must manually create and configure user accounts in multiple systems to onboard new employees. IGA tools streamline the process by automatically provisioning appropriately permissioned accounts across all required systems in real time based on the user’s role.

Like IT architectures, cyberattacks have evolved, with threat actors increasingly targeting identities rather than network infrastructure. According to the IBM X-Force® Threat Intelligence Index, abuse of valid accounts is one of the most common attack vectors for hackers breaking into enterprise networks, accounting for 32% of cyberattacks.

A single identity system can control access to many environments at once, so compromising one account can unlock multiple domains simultaneously. And today’s employees can log in to their accounts and access corporate resources from anywhere, on any device. Traditional, perimeter-based security is no longer sufficient for protecting IT environments.

IGA solutions help enterprises shrink this attack surface and limit the damage that attackers can cause by enforcing the principle of least privilege (PoLP). That is, users have only the access necessary to do their job functions—no more, no less.

IGA solutions also help improve an organization’s security posture by facilitating:

To further protect high-risk privileged accounts with elevated access rights, organizations frequently integrate IGA with privileged access management (PAM) tools, which focus specifically on securing privileged accounts, such as admin accounts.

Some IGA solutions also offer real-time threat detection and remediation capabilities to help prevent compliance violations and data breaches.

Compliance requirements such as GDPR, HIPAA, SOX and other mandates impose rules on how organizations handle data. Penalties for noncompliance can be significant. For instance, GDPR violations can result in fines up to EUR 20 million or 4% of global annual revenue, whichever is higher.

IGA solutions provide controls and documentation that organizations can use to streamline compliance:

A healthcare provider, for example, can use IGA tools to enforce HIPAA compliance by restricting access to patient records based on job responsibilities and maintaining detailed logs of who accesses records.

IGA doesn’t just govern and provision human identities. It also manages nonhuman identities (NHIs), such as service accounts, machine identities, cloud workload identities and AI agents.

The rapid growth of cloud computing, artificial intelligence and machine learning has driven explosive NHI adoption, with nonhuman identities now far outnumbering human users. Estimates range from 45:1 to 92:1.

NHI growth at this scale introduces serious security challenges. NHIs can multiply quickly across tools, pipelines and cloud environments, and many organizations lack an accurate inventory of active NHIs. These dynamics encourage identity sprawl and create monitoring gaps that widen the attack surface.

Without robust IGA processes, sensitive NHI credentials can be hardcoded into source code, stored in plain‑text configuration files, committed to shared repositories or circulated in chat and ticketing systems. Hackers can easily steal these credentials. Credential harvesting drove 26% of all cybercrimes in 2025 according to the X-Force Threat Intelligence Index.

And when governance controls are weak, developers might configure tokens or keys with “permanent” lifetimes, which simplifies daily operations but leaves long‑lived credentials available for indefinite abuse.

IGA tools help enterprises manage NHIs by defining policies for provisioning and deprovisioning them. This process helps ensure that new NHIs and machine identities are approved, appropriately scoped and automatically cleaned up when they are no longer needed.

IGA can also help IT teams control identity sprawl by automatically discovering and cataloging NHIs, so security teams can see where the identities exist and what they can access. IGA platforms can also assign each NHI a human owner and documented business purpose, creating a clear accountability structure for managing NHIs.

IGA tools and practices focus on governing digital identities and permissions throughout the user lifecycle, from onboarding to offboarding. The two main components of IGA are identity lifecycle management and access governance.

Identity lifecycle management entails creating, modifying and deactivating user identities for joiners (employees who join an organization), movers (employees who move within an organization) and leavers (employees who leave an organization). It helps ensure that new users receive appropriate access from day one and that access is promptly removed during offboarding.

If an employee changes roles, IGA tools can automatically revoke outdated permissions and assign new ones based on their updated responsibilities. 

Key identity lifecycle management processes include:

• Onboarding: Provisioning user accounts and initial access for joiners.

• Attribute changes: Updating access rights for movers when their attributes (security clearance, department, project assignment) change.

• Offboarding: Deprovisioning access when leavers exit the organization.

Access governance oversees users’ access to resources. It provides the oversight layer for identity management, focusing on policy enforcement, access reviews and compliance.

Key access governance functions include:

• Role-based access control (RBAC)
• Separation of duties (SoD) enforcement
• Access certification and reviews
• Entitlement management

Role-based access control (RBAC) assigns permissions to users based on organizational roles rather than assigning individual permissions to each user. For example, a finance role might authorize a user to make purchases, while a human resources role might authorize a user to see personnel files.

Role management capabilities in IGA solutions help organizations define, manage and maintain roles over time.

With RBAC, IGA solutions can manage access for thousands of users simultaneously. When an employee joins, transfers departments or leaves, administrators can simply assign or remove standardized roles rather than reconfiguring dozens of separate system permissions.

Separation of duties (SoD), also called segregation of duties, is a security principle that prevents conflicts of interest by ensuring no single person has excessive privileges.

IGA solutions help enforce SoD by identifying and preventing combinations of entitlements that can lead to fraud or misuse.

In a procurement process, for instance, the same person should not be able to both add a new vendor to the system and approve payments to that vendor. An IGA solution can flag this arrangement as a SoD violation and either block it entirely or require additional approvals.

Access certification—or attestation—involves periodically reviewing user access rights to eliminate orphaned accounts and prevent privilege creep. These reviews typically involve managers or resource owners confirming that team members still need their current privileges.

According to the X-Force Threat Intelligence Index, 15% of all cyberattacks exploit incorrectly configured access control security levels, making access certification vital to effective IGA strategies.

IGA solutions help streamline the review process by automatically initiating reviews on a regular basis. High-risk rights—such as access to financial systems—might be reviewed more frequently than lower-risk permissions. Some IGA solutions can also make recommendations for access changes based on usage patterns, such as flagging unused permissions that a user might not need.

Entitlement management is a more granular component of access governance, focusing on the permissions users have within systems. Put another way: access governance oversees what users can access, while entitlement management oversees what users can do with that access.

For example, in an accounting system, entitlement management would dictate which users can view financial records, which users can edit them and which users can delete them.

Additional capabilities include:

• Entitlement cataloging: Maintaining an inventory of user permissions.

• Access risk assessment: Evaluating the risk associated with specific entitlements, such as the ability to modify customer credit limits.

• Policy-based controls: Enforcing security policies during access requests to maintain least-privilege principles, such as requiring supervisor approval for access to sensitive financial data.

• Access analytics: Providing insights into access patterns to help organizations proactively address potential unauthorized access risks (for example, detecting when users have excessive permissions for critical systems).

Many businesses are moving toward identity-first security practices, which treat users, service accounts, application programming interfaces (APIs), devices and workloads as the primary control plane—or perimeter—for threat detection and prevention. IGA can help organizations adopt identity-first security through real-time monitoring and policy enforcement.

In an identity-first environment, every asset and action is tied back to an identity and its entitlements. Detection and response tools actively use governance data to spot abnormal or unauthorized identity behavior. IGA changes from a periodic review tool to a live security control that feeds risk signals and policies into enforcement points.

To implement identity-first security practices, some enterprises are turning to converged security frameworks called identity fabrics. Identity fabrics take IGA and surround it with other identity security capabilities to create one unified architecture. Common capabilities include cloud infrastructure entitlement management (CIEM), risk-based authentication (RBA), identity detection and threat response (IDTR), PAM and access management tools.

IGA remains the source of truth for identities and access, and the identity fabric adds enforcement, monitoring and cloud‑specific controls around that governance layer.

In this framework, the identity and role data from IGA drives PAM policies (which dictate how privileged accounts are used), and PAM events feed back into IGA for governance. For example, if a PAM tool discovers an account has unused privileges, IGA can remove those privileges.

CIEM tools map fine-grained cloud roles and permissions. They use IGA data to configure cloud entitlements and front-door access rules, helping ensure that cloud roles, SaaS permissions and on-premises permissions are governed uniformly. CIEM platforms also export data back to IGA so that cloud identities can be governed, certified and rightsized.

ITDR systems continuously check what an identity is doing in the network, responding to risky or compromised behavior across the fabric. ITDR consumes events and context from IGA and other IAM components. When an ITDR tool detects a threat, it can trigger IGA workflows (out-of-cycle certification or emergency deprovisioning, for example).

Risk-based authentication (RBA)—also called adaptive authentication—dynamically adjusts how much identity verification is required of a user based on the context of the login attempt. RBA tools feed risk scores and anomalies into IGA systems, and they consult IGA systems to decide which apps a user can reach and when to step up authentication or deny access.

These systems, along with identity and access management and session control systems—such as single sign-on (SSO) and multifactor authentication (MFA)—converge to create a single access control chain across the entire network. IGA’s potential is maximized, and enterprise IAM practices are streamlined.

Advances in AI are bringing both new challenges and new opportunities to IGA.

Threat actors are using generative AI tools to target IGA workflows and controls. For example, by using AI to generate deepfakes and convincing phishing messages, attackers can trick legitimate users into handing over their credentials. More sophisticated actors might even use machine learning tools to analyze permission structures and identify opportunities for policy evasion to get around IGA controls.  

At the same time, vendors are using AI to transform their IGA solutions from static compliance checkpoints into adaptive risk management systems. Some examples of how IGA solutions are using AI include:

AI-based access modeling compares an individual user’s access to that of peers with similar attributes (department, job function, location) to determine what access is normal or anomalous for that person. This functionality enables IGA solutions to recommend roles and entitlements, dynamically create new roles when patterns emerge and flag outliers who might be overprivileged or misconfigured.

Role mining enables IGA tools to glean meaningful roles and entitlements from real-world usage data. Machine learning algorithms can analyze which users have which permissions, how they use their permissions and how users cluster together. Based on this data, the IGA tool can propose cleaner, more consistent role structures that reduce excessive access.

Traditional access certification campaigns—periodic reviews of who has what access—are labor-intensive for managers and compliance teams. AI-enabled IGA tools provide recommendation engines and confidence scores that can evaluate and score entitlements (based on privilege level, usage and SoD impact). The system can then identify which entitlements are appropriate and which merit closer scrutiny.

Some platforms also support microcertifications, where low-risk, high-confidence access is auto-approved and only a small set of ambiguous or high-risk items require human review.

AI-driven IGA platforms can analyze existing approval flows, SoD rules and business processes to suggest more efficient, more compliant workflows. Administrators can collaborate with AI to design, test and deploy automated workflows that are preemptively optimized for risk reduction and regulatory alignment, so they don’t have to hand-code every rule.
