What is a CASB?

A CASB stands for "Cloud Access Security Broker." It is a security software that is designed to protect an organization's data and systems when they are accessed from the cloud.

A CASB sits between an organization's users and the cloud applications that they access, and it is responsible for enforcing security policies and controls. It can be used to monitor and control user activity, enforce access controls, protect data in transit and at rest, and detect and prevent security threats.

CASBs are often used to secure access to software-as-a-service (SaaS) applications, such as office productivity tools, customer relationship management (CRM) systems, and human resource management (HRM) systems. They can also be used to secure access to infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS) offerings, such as cloud storage and cloud computing platforms.

CASBs provide an additional layer of security for organizations that use cloud services, and they are an important part of any cloud security strategy.
