A Virtual Private Network (VPN) primarily secures data in transit by encrypting network traffic, but it does not provide continuous monitoring of all cloud resources, real-time threat alerts, or consistent security policy enforcement across diverse cloud workloads.

A Cloud Access Security Broker (CASB) serves as a security policy enforcement point between cloud consumers and providers, offering crucial capabilities such as comprehensive visibility into cloud usage, continuous monitoring for compliance, real-time threat detection and alerting, and consistent application of data loss prevention and security policies across all cloud workloads. These features directly address the client's need for high-level security control, continuous monitoring, real-time alerts, and consistent policy enforcement.

Multi-factor authentication (MFA) enhances identity security by requiring multiple verification factors for user access, but it does not offer continuous monitoring of cloud resources, real-time threat detection alerts beyond authentication, or broad security policy enforcement across all cloud workloads.

Client-side encryption protects data at rest by encrypting it before it leaves the client's control, but it does not provide continuous monitoring of cloud resources, real-time threat alerts, or consistent security policy enforcement across all cloud workloads.
