CASB (Cloud Access Security Broker) is a security solution that acts as an intermediary between users and cloud services, enforcing security policies, compliance, and data protection. It helps organizations monitor and control cloud application usage, detect and prevent threats, ensure regulatory compliance, and secure sensitive data across Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) environments.
A CASB typically provides four key functionalities:
- Visibility – Identifies and monitors cloud applications in use, including shadow IT.
- Compliance – Ensures adherence to regulatory and internal security policies.
- Data Security – Protects sensitive data through encryption, tokenization, and access controls.
- Threat Protection – Detects and prevents malware, insider threats, and unauthorized access.
CASBs can be deployed in different modes, such as API-based integration, proxy (forward/reverse), or hybrid approaches, depending on organizational needs.
