Cloud Access Security Broker Software (CASB) helps organizations secure cloud applications by enforcing security policies, detecting threats, and preventing data loss. Leading tools include Netskope, Microsoft Defender for Cloud Apps, Zscaler CASB, Cisco Cloudlock, and McAfee MVISION Cloud. These platforms provide visibility into cloud usage, protect sensitive data, and ensure compliance across SaaS, PaaS, and IaaS environments.

Cloud Access Security Broker (CASB) software is a security layer positioned between users and cloud service providers that enforces enterprise security policies, monitors activity, and protects data across cloud environments.

As organizations rapidly adopt cloud applications, they face challenges such as shadow IT, data breaches, compliance risks, and lack of visibility into user activity. CASB solutions address these issues by providing centralized control over cloud access, enabling organizations to detect unauthorized applications, enforce data protection policies, and monitor user behavior.

Modern CASB platforms offer capabilities such as data loss prevention (DLP), threat detection, encryption, access control, and real-time monitoring. These tools integrate with SaaS platforms like Microsoft 365, Google Workspace, and Salesforce to ensure secure usage across distributed environments.

Advanced CASB solutions leverage AI and behavioral analytics to identify anomalies, prevent insider threats, and automate security responses. They also support compliance frameworks such as GDPR, HIPAA, and PCI DSS, making them essential for enterprises operating in regulated industries.
