What Is Identity and Access Management (IAM)?
Identity and Access Management (IAM) is the framework of policies, technologies and processes used to ensure the right people have access to the right systems, applications and data at the right time.
IAM helps organisations control user identities, manage permissions, strengthen authentication and reduce cyber security risks associated with unauthorised access.

Identity and Access Management Explained
Every organisation has users who need access to systems, applications, email, cloud platforms and business data. IAM ensures users can access what they need while preventing unauthorised access to sensitive information.
IAM answers three important questions:
Who are you?
What are you allowed to access?
How do we verify your identity?
Why IAM Is Critical for Cyber Security
Most modern cyber attacks target user accounts rather than networks. Attackers attempt to steal passwords, compromise Microsoft 365 accounts and gain access to business systems.
Prevent Unauthorised Access
Restrict access to systems and data based on business need.
Reduce Insider Risk
Limit excessive permissions and administrator access.
Protect Sensitive Data
Control who can view, edit or share information.
Core Components of IAM
Single Sign-On (SSO)
Allows users to access multiple applications using one identity.
Role-Based Access Control
Users receive permissions based on their role within the organisation.
Identity Governance
Ensures identities remain secure throughout their lifecycle.
Privileged Access Management
Protects administrator and highly privileged accounts.
