A Cloud Access Security Broker (CASB) is a security solution that acts as an intermediary between users and cloud service providers, enforcing organizational security policies as cloud-based resources are accessed. CASBs provide visibility and control over data and user activity in cloud applications, addressing security gaps that arise from the adoption of cloud services. Core capabilities of CASBs include data loss prevention, threat protection, access control, and compliance monitoring across multiple cloud environments. These solutions typically integrate with both sanctioned and unsanctioned cloud applications, offering granular policy enforcement, user behavior analytics, and encryption or tokenization of sensitive data. CASBs also facilitate the detection of shadow IT by identifying unauthorized cloud usage within an organization. Security and IT teams in enterprises and mid-sized organizations are the primary users of CASB solutions. They deploy CASBs to manage risks associated with cloud adoption, ensure regulatory compliance, and maintain consistent security controls across diverse cloud platforms. Unlike traditional secure web gateways or endpoint protection platforms, CASBs are specifically designed to address the unique challenges of cloud application security, providing visibility and policy enforcement at the intersection of users and cloud services.
