Introduction

Cloud Access Security Brokers (CASB) are security platforms that sit between cloud service users and cloud applications to enforce enterprise security policies. They provide visibility, compliance, threat protection, and data governance for cloud services. In plain English, CASBs help organizations monitor and control cloud usage to prevent data breaches, misconfigurations, and insider threats.

As cloud adoption accelerates in +, enterprises increasingly rely on multiple SaaS applications, IaaS, and PaaS platforms. Without a CASB, organizations struggle to secure data, maintain compliance, and enforce consistent policies across diverse cloud environments. CASBs act as centralized security controls, providing visibility into cloud usage, detecting risky activities, and enabling automated remediation.

Real-world use cases:

• Discovering and controlling unsanctioned cloud apps (shadow IT).
• Enforcing data loss prevention (DLP) policies for SaaS and cloud storage.
• Monitoring user activity and access patterns for insider threats.
• Detecting malware, ransomware, and compromised accounts.
• Ensuring compliance with regulatory frameworks like SOC 2, ISO 27001, HIPAA, and GDPR.

Evaluation criteria buyers should consider:

• Coverage across SaaS, PaaS, and IaaS platforms.
• Real-time monitoring and threat detection.
• Data loss prevention (DLP) capabilities.
• User behavior analytics and risk scoring.
• Policy enforcement and access control.
• Automated remediation and alerts.
• Reporting and compliance dashboards.
• Ease of deployment and administration.
• API integrations for SIEM, ITSM, and automation workflows.

Best for: Security teams, IT administrators, CISOs, and compliance officers in medium to large organizations with complex cloud usage.

Not ideal for: Small organizations with minimal cloud adoption or few SaaS apps, where native cloud security features may suffice.
