What is CIAM (Customer Identity and Access Management)?

CIAM solutions deliver trusted experiences, while also protecting customer identities

What is Customer Identity & Access Management (CIAM)?

Customer Identity and Access Management (CIAM) is a type of identity and access management (IAM) that integrates authentication and authorization into customer-facing applications. CIAM does three main things:

  1. Improves customer registration and login experiences while reducing the risk of account takeover (a rampant problem in the consumer space because of password reuse.)
  2. Offers customized and branded experiences for consumers, businesses, and enterprise customers.
  3. Provides a scalable solution that can support hundreds of millions of customers.

CIAM Key Benefits

Customer identity management is an important security measure across businesses of all shapes and sizes. Breaches can get expensive very quickly, often making a substantial impact on the bottom line. According to IBM Security, 80% of breached organizations have stated that customer PII was compromised during the breach and on average the cost of breach is $150 per customer. CIAM solutions can be easily integrated with systems that control common customer tasks such as account self-management, bill paying, order tracking, and returns, reducing the risks associated with poor password hygiene.

Key benefits of CIAM include:

  • Identity and Access Management: IAM solutions securely manage digital identities and their access to various applications and systems. They manage people and also other kinds of identities, such as software (apps or programs), and hardware (such as IoT devices)
  • Customer data protection (MFA and Adaptive Authentication): Consumers are notorious for reusing passwords for the dozens of services they use online. Advanced CIAM solutions protect those passwords with adaptive multi-factor authentication (MFA), which looks at various contextual factors like location, time of day, and device. It supports even stronger security by increasing authentication requirements for high-risk login attempts.
  • Seamless and trusted digital customer experiences: Many companies have multiple web applications and portals, each with its own identity store, requiring users to authenticate multiple times when switching between different applications. This creates additional friction during the login process. By integrating all your digital channels with a single CIAM solution, you can provide a more seamless user experience: one point of entry for all the applications.
  • Quick migration of users without interrupting the user experience: A CIAM solution should work with your existing system to quickly migrate your customers without impacting the experience.
  • Customization with flexible APIs: When building applications, developers want to ensure a seamless customer experience for securing access to digital resources. APIs provide the flexibility needed to customize authentication requirements throughout the development lifecycle.
  • Multichannel support (mobile, laptop, game consoles, etc): The best solutions offer a diversity of entry points across all devices, making it as easy as possible for customers to access the tools they need to run their business.
  • Account self-service: A CIAM solution should empower the user to solve their problems through a self-service platform that allows them to reset passwords and go through authentication protocols without involving an IT professional.
  • Application lifecycle management: Businesses at any stage may be developing and deploying products that are being managed across a number of platforms. A comprehensive CIAM solution helps manage that process seamlessly.
  • Compliance with security and privacy standards like HIPAA and ISO: The ability to integrate additional security measures that apply to particular sectors like healthcare and international organizations.
  • Customer analytics: The ability to run comprehensive reporting around customer behavior is important for making key business decisions. Using customer analytics as a reference point, businesses can increase conversions, improve retention, supporting upselling and cross-selling messaging.
  • Scalability and high availability: A good enterprise solution needs to be able to support a high volume of users with as little delays and downtime as possible.


CIAM and IAM requirements are similar when it comes to scalability, security, and accessibility. Both must meet these three requirements to guarantee a great user experience, whether for internal employees or external customers. However, CIAM goes beyond the traditional IAM approach in the following ways:




Limited users (10–100,000) with less capability to handle spikes in traffic

A CIAM portal must be able to support millions of users. It also has to be able to handle rapid spikes in traffic (volume and frequency). Use of the portal is unpredictable, but there will be peak times when many people are accessing your system at the same time, such as Black Friday, and your CIAM solution must be able to handle those peaks.

Single identity per user

Consumers can have multiple identities

Company registration


Closed system

Highly accessible system available on any device with a consistent login experience no matter where the end-user is or what device they’re using.

Internal authentication with strict security policies

CIAM must be implemented in a way that keeps the barrier of entry low. Authentication with external sources like social providers (e.g., Google, LinkedIn) reduces friction by enabling passwordless authentication without compromising on security.

Employee access and profile data used for internal purposes

Customer data used to provide critical analytics around marketing, business decisions, security, and compliance.

How Does CIAM Protect Customer Data?

Consumers have to remember a lot of passwords, and good CIAM vendors know that customer identity management is important for the security of the individual and the company. Whether it’s their social media, online banking, or online streaming accounts, the number quickly adds up. As consumer services are breached around the world, hackers accumulate even more user credentials, which are sold and bought online to launch large-scale password stuffing attacks using extensive bot networks.

This puts consumers who reuse passwords at particular risk. With CIAM, you can give the consumer the option to add a second authentication factor or sign in with their social identity, which provides stronger protection against account takeover.

Customers are given access to a customized, secure login portal with an authentication requirement. This portal is managed by the IT department, which keeps all security software, checks, and protocols up to date behind the scenes, protecting against ever-increasing viruses and hackers.

In the past, companies only gave customers one option for signing in: username and password. Now that MFA is commonplace, applications often require two or more factors before granting users access. To ensure that adding MFA is not discouraging users from creating accounts or slowing down their experience, CIAM must be implemented in a way that keeps the barrier of entry low.

Adaptive authentication uses risk scoring to determine whether or not MFA is required at the time of login. The risk score is a calculation of the risk level at the time of login that determines whether or not the end user will be granted access or will require a second level of authentication. Location, time, and frequency are some of the criteria used to determine the risk score.
