Cloud Access Security Broker (CASB)

A Cloud Access Security Broker (CASB) is a security solution that acts as a gatekeeper between an organisation's on-premises infrastructure and cloud service providers. CASBs provide visibility, security controls, and policy enforcement across cloud services to protect sensitive data and ensure compliance with regulatory requirements.

CASBs help organisations manage the risks associated with cloud usage by monitoring user activity, detecting threats, enforcing access controls, and securing data.

Key functions of a CASB include:

  • Monitoring and controlling access to cloud applications
  • Enforcing security policies such as data encryption and data loss prevention (DLP)
  • Detecting and mitigating cloud-related threats

 Implementing CASB involves: 

  • Integrating with existing cloud services and applications
  • Applying access controls and policies to protect data
  • Monitoring user activity for compliance and risk management

 CASBs are essential for securing cloud environments by ensuring safe and compliant access to cloud-based resources and applications.
