CIAM VS IAM: Understanding the Key Differences

CIAM versus IAM - Why can’t one software answer all your problems? Well IAM is aimed at employees while CIAM is for customers or clients - both have different problems.

According to Statistica, from March 2023 to February 2024 - the average cost for a company data breach was an astounding 9.36 Million USD. Both CIAM and IAM software can protect users from this - but here are the ways they differ in doing this.

What is an IAM Software (Identity and Access Management)?

IAM or Identity and Access Management Software is a framework of tools and policies designed to manage the identities and permissions of users within a company. Its primary goal is to make sure that only authorized users can access specific systems and resources. 

This is essential for maintaining operational security and meeting compliance requirements in enterprise environments.

Key Elements of an IAM Software or Tool

• User Provisioning and De-provisioning: Automated processes for granting and revoking access as employees join, change roles, or leave the company.
• Role-Based Access Control (RBAC): Assigning permissions based on job functions to make sure that users only access what they need.
• Single Sign-On (SSO): A unified login experience across multiple systems to improve usability and security.
• Multi-Factor Authentication (MFA): Adding layers of security through methods like OTPs or biometrics.
• Audit Trails: Logs to track who accessed what and when are crucial for compliance and forensic investigations.

What is Customer Identity and Access Management (CIAM)?

CIAM or Customer Identity and Access Management manages and secures the identities of customers and external users (namely app users or users on a platform for a service). It aims to create an easy and secure experience while gathering insights to enhance customer engagement. Unlike IAM, CIAM prioritizes user experience alongside security.

Key Elements of a CIAM Software or Tool

• Scalable Authentication: Handling high volumes of user logins during peak times without performance issues.
• Social Login Options: Allowing users to log in with social media accounts like Facebook or Google.
• Consent Management: Tools to manage and honor user preferences and GDPR or CCPA compliance.
• Personalization: Using identity data to tailor user experiences and offers.
• Fraud Detection: Identifying and stop fraudulent activities specific to customer-facing systems.

9 Ways IAM and CIAM Platforms Differ From Each Other
