What is Identity Governance and Administration (IGA) and Why Is It Not Enough?

Introduction

As businesses embrace digital transformation, managing user identities and their access to critical systems becomes more important than ever. Identity Governance and Administration (IGA) has emerged as a foundational component of identity security strategies. But is IGA alone sufficient for today’s complex cybersecurity landscape? In this blog, we’ll explore what IGA is, its core benefits, and crucially—why relying solely on IGA is not enough for robust identity and access security.

What is Identity Governance and Administration (IGA)?

Identity Governance and Administration (IGA) refers to the policies, processes, and technologies that help organizations manage digital identities and regulate user access to applications, data, and IT resources. IGA is designed to answer the essential questions: “Who has access to what?” and “Should they have that access?”

Key Functions of IGA

• Identity Lifecycle Management: Automates the creation, modification, and deletion of user accounts.
• Access Requests and Approvals: Provides workflows for users to request access and for managers to approve or deny.
• Access Certification: Enables regular reviews and certifications of user access rights to ensure compliance.
• Policy Enforcement: Implements access policies based on roles, attributes, or other criteria.
• Audit and Reporting: Offers visibility into who accessed what and when, aiding compliance and investigations.

Benefits of IGA

• Improved Compliance: Helps meet regulatory requirements (GDPR, SOX, HIPAA, etc.).
• Operational Efficiency: Automates manual processes, reducing errors and workload.
• Risk Reduction: Detects and remediates inappropriate or risky access.

Why Identity Governance and Administration Is Not Enough

While IGA is essential, it is not a silver bullet. Modern threats and evolving business needs require a layered, adaptive approach to identity security. Here’s why IGA alone is not enough:

1. Insider Threats and Privilege Abuse

IGA manages and audits access, but it cannot always detect or prevent malicious or careless actions by authorized users—especially if those users have excessive privileges.

2. Dynamic Environments

Today’s businesses operate in hybrid and multi-cloud environments where users, devices, and resources are constantly changing. Static IGA policies may struggle to keep up with:

• Contractors and temporary workers
• Non-human identities (service accounts, bots)
• Rapid onboarding/offboarding needs

3. Sophisticated External Attacks

Modern cyberattacks often exploit stolen credentials, social engineering, or lateral movement after initial access is granted. IGA lacks real-time threat detection and response capabilities to stop active attacks in progress.

4. Lack of Continuous Authentication

IGA primarily governs access at provisioning time, not during session use. It doesn’t assess changing risk factors in real time, such as unusual login locations or suspicious activity, leaving gaps in ongoing protection.

5. Compliance is Not Security

Meeting compliance checkboxes with IGA doesn’t guarantee real-world security. Attackers don’t care if you’re compliant—they look for gaps to exploit.

What Complements IGA? A Layered Approach

To truly secure identities and access, organizations must supplement IGA with:

• Identity and Access Management (IAM): Enforces access policies at login.
• Privileged Access Management (PAM): Controls and audits access for users with elevated privileges.
• Identity Threat Detection and Response (ITDR): Provides real-time monitoring, analytics, and automated response to identity-based threats.
• Zero Trust Principles: Continually verifies every user and device, regardless of location.

Conclusion

Identity Governance and Administration (IGA) is the backbone of effective identity management, ensuring proper access controls, compliance, and streamlined processes. However, relying on IGA alone leaves organizations exposed to insider threats, dynamic changes, and sophisticated cyberattacks. A holistic, layered approach—combining IGA with IAM, PAM, threat detection, and Zero Trust—is the key to protecting your digital assets in today’s ever-evolving threat landscape.

FAQs

Q: Is IGA the same as IAM?
A: No. IGA focuses on governance, policy, and auditing, while IAM is about authentication and enforcing access controls.

Q: Can IGA stop phishing attacks?
A: Not directly. IGA manages access, but stopping phishing requires additional controls like MFA, real-time monitoring, and user education.

Q: What should I implement with IGA for better security?
A: Consider Privileged Access Management, Identity Threat Detection, and Zero Trust principles.
