Identity is the new perimeter. In a world where applications run in the cloud and users work from anywhere, the corporate network boundary no longer defines the security boundary. Who you are — verified by strong authentication, governed by least-privilege access policies, and monitored for anomalous behaviour — determines what you can access.
Multi-factor authentication (MFA) is the single security control with the highest documented impact on attack prevention. Microsoft reports that MFA blocks over ninety-nine percent of account compromise attacks. Despite this, MFA adoption in Indian enterprises remains incomplete — many organisations have deployed it for external-facing systems but not for internal applications, privileged access, and administrator accounts. Complete MFA deployment is the first priority in any IAM improvement programme.
Privileged Access Management (PAM) addresses the specific risks of administrator, service account, and emergency access. These accounts have elevated permissions that, if compromised, enable attackers to move freely and cause maximum damage. PAM solutions — CyberArk, BeyondTrust, Delinea — provide vaulted credential storage, just-in-time access (temporary, time-limited elevated access that expires automatically), session recording for audit, and approval workflows for sensitive operations.
Single Sign-On (SSO) with a centralised identity provider — Okta, Microsoft Entra, Google Workspace — is both a security and user experience improvement. A user authenticating once to their IdP and accessing all applications without additional login prompts is more secure than a user maintaining separate credentials for each application (which typically results in weak, reused passwords) and more productive.
Access reviews — periodic certifications where managers confirm that their direct reports still require the access they have — prevent access accumulation over time. Employees who change roles often retain access from previous roles. Departed employees may retain access if offboarding is incomplete. Automated access review workflows make this governance tractable at scale.
