A company has been migrating a significant number of its on-premises applications to various SaaS providers. The IT department has noticed the following: 1. User account management has become…

Single sign-on is an outcome or a feature enabled by technologies like federation, rather than the core underlying implementation technique itself in this context where federation is also an option.

Multifactor authentication (MFA) adds a crucial layer of security beyond passwords, significantly reducing the risk of user account compromises even if credentials are stolen.

A network intrusion prevention system protects against network-based attacks but does not directly address user account management, identity compromises, or access challenges with SaaS applications.

Password synchronization simplifies user account management and access by ensuring consistent passwords across multiple SaaS applications, reducing user friction and IT overhead.

Federation establishes a trusted relationship between the company's identity provider and various SaaS providers, enabling centralized user management and single sign-on (SSO) for simplified and secure access.

An IPSec tunnel provides secure network connectivity between the company and SaaS providers but does not resolve issues related to user identity management, authentication, or account compromises.

A VPN provides secure network access to resources but, like IPSec, it does not directly solve the problems of user account management, increased compromises, or simplified application access at the identity layer.
