Identity Governance and Administration (IGA) enables security administrators to efficiently manage user identities and access across the enterprise. It improves their visibility into identities and access privileges and helps them implement the necessary controls to prevent inappropriate or risky access.
IGA combines Identity Governance and Identity Administration. Identity Governance is about visibility, segregation of duties, role management, attestation, analytics and reporting, while Identity Administration is related to account administration, credentials administration, user and device provisioning and managing entitlements.
In enterprise settings, increasing digitization means more devices, users and data across on-premises and multi-cloud/remote environments. In such complex IT-security ecosystems, it’s difficult to effectively manage user identities and access. But if users are given excessive or unnecessary access to systems, applications or data, it increases security risks, the volume of cyber threats, and makes the organization vulnerable to cyberattacks and data breaches.
With IGA solutions, security personnel can track and control user access for both on-premises and cloud-based systems, as part of the cloud governance efforts. They can secure users by ensuring that the right user accounts have the right access to the right systems and detect and prevent inappropriate access. By implementing the right controls with IGA, enterprises can minimize risk and maintain regulatory compliance.
IGA solutions enable enterprises to accurately and efficiently streamline user identity lifecycle management. Security administrators can automate the process of provisioning and de-provisioning user access throughout their access lifecycle. To enable this automation, IGA solutions work with Identity and Access Management (IAM) processes. IGA also works with IAM to help admins manage permissions and maintain compliance with accurate reporting.
IGA systems generally include these elements for Identity Administration (IA):
Connectors enable IGA tools to integrate with directories and other enterprise systems that contain information about users, the applications and systems they have access to and their authorization within those systems. These connectors read this data to understand who has access to what, and to write data to create new users and grant them access.
That brings us to federated identities. A federated identity allows authorized users to access multiple applications and domains using a single set of credentials. It links a user's identity across multiple identity management systems so they can access different applications securely and efficiently.
Automated workflows make it easier for users to request access to the systems they need to do their work. Moreover, admins can easily onboard and offboard users, determine which roles require which level of access to applications and systems and approve user access.
IGA streamlines the process of automated provisioning and de-provisioning access permissions at the user and application level – for both on-premises and cloud-based resources.
Security admins can specify and verify what users are allowed to do in various applications and systems. For example, some users may be able to add or edit data, while others may only be allowed to view data. A few may also have permissions to delete data.
IGA systems generally include these elements for Identity Governance (IG):
To avoid error and prevent fraud, security teams can create rules that prevent risky sets of access or transaction rights from being granted to a single person. For example, SoD controls would prevent a user from being able to both view a corporate bank account and transfer funds to outside accounts, either carelessly or with malicious purposes. SoD controls should be in place within a given application, as well as across multiple systems and identity access management applications.
IGA solutions streamline the process to review and verify user access to various apps and resources. They also simplify access revocation (for example, when a user leaves the organization).
This is where strong authentication comes in play. Strong authentication is a method used to secure computer systems and/or networks by verifying a user’s identity by requiring two-factors in order to authenticate (something you know, something you are, or something you have).
With role-based access control (RBAC), user access is determined according to their role, so they can only access the information necessary to perform their job duties. By preventing unnecessary access – especially to sensitive data – RBAC increases enterprise security and prevents breaches.
These IGA solutions provide visibility to user activities and enable security personnel to identify security issues or risks and raise alarms in high-risk situations. They can also suggest security improvements, start remediation processes, address policy violations and generate compliance reports.
As user associations within the organization change (for example, because they transfer to a different department or leave the organization) access requirements also change. IGA makes it easy to manage these changes, from provisioning to de-provisioning. IGA also helps maintain control over users, devices, networks and other IT resources through password management, permissions management and access requests management.
An IGA system provides a centralized approval location, making it easy for users to ask for the access approvals they need to fulfill their responsibilities. Centralization also enables administrators to manage permissions, track and detect suspicious activities and prevent potential threat actors from accessing enterprise systems or data.
Detailed reports and analytics help IT admins to understand what’s happening across the enterprise environment and quickly find any issues or risks. They can then troubleshoot problems to protect business-critical resources. Data centralization also enables admins to audit access reports to meet compliance requirements.
With robust IGA solutions, organizations can safely allow and control remote access to maintain business continuity while also preventing breaches. Such flexibility enables employees to work from anywhere, and thus improve their productivity and performance.
IGA solutions support centralized policies and automated workflows that help reduce operational costs, ensure that employees can access the resources they need, reduce risk and improve compliance. All these benefits allow the organization to scale organically, which they wouldn’t be able to do with manual processes or limited visibility into users, identities and systems.

Regulations are meant to protect users and/or data and increase trust between various entities. For example, GDPR was created to protect personal data and the Health Information Portability and Accountability Act (HIPAA) was created to safeguard users’ health care information. It requires health care organizations to implement appropriate safeguards to ensure the security and privacy of patient data.
Similarly, the Sarbanes-Oxley Act (SOX) imposed mandates to improve financial record-keeping and audits in publicly traded companies. The aim is to bolster trust in companies’ financial information and prevent fraud. Another regulation, the Payment Card Industry Data Security Standard (PCI DSS) specifies requirements around security management, policies and procedures to protect customers’ credit card data.
It’s important for organizations to comply with all regulations that apply to them in order to avoid the legal or financial penalties of non-compliance. Compliance also enables them to earn customers’ trust and grow their business. Regulatory compliance also means that they have the controls in place to safeguard their systems and data, which protects them from cyberattacks and data breaches.
IGA is a sub-category of Identity and Access Management (IAM). However, IGA systems provide additional functionality beyond standard the IAM solution and help address common IAM challenges.
For example, inappropriate and/or outdated access to enterprise resources is a common problem in IAM. A remote workforce, time-consuming provisioning processes, weak Bring Your Own Device (BYOD) policies and strict compliance requirements are some other identity management system challenges. These issues increase security risk and weaken organizations’ compliance posture. However, organizations can address these challenges by strengthening their identity solutions with IGA.
With IGA, organizations can automate the workflows for access approvals and to reduce risk. They can also define and enforce IAM policies and audit user access processes for compliance reporting. That’s why many organizations use IGA to meet the compliance requirements laid out in GDPR, HIPAA, SOX and PCI DSS.
