Cloud Access Security Broker (CASB) Software

Cloud Access Security Broker (CASB) software helps organizations monitor and control how cloud applications are used across their environment. It sits between users and cloud services to provide visibility into activity, enforce security policies, and reduce risk when employees access data from SaaS platforms, web apps, and other cloud resources. For buyers comparing the best CASB software, the category is often evaluated based on how well it supports cloud governance without slowing down day-to-day work.

IT teams, security operations staff, compliance leaders, and cloud administrators typically use CASB tools to protect sensitive data and manage access across multiple cloud services. Common use cases include discovering shadow IT, preventing data loss, applying encryption or tokenization, and detecting unusual user behavior that may signal a threat. These top CASB tools also help organizations align with internal policies and external requirements by giving administrators more control over how information moves through cloud environments.

Typical features include activity monitoring, access controls, data classification, threat detection, policy enforcement, and reporting dashboards. Some platforms also support integration with identity providers, secure collaboration tools, and incident response workflows. By combining visibility, governance, and protection, CASB software helps businesses reduce cloud-related risk, improve compliance oversight, and manage access more consistently across distributed teams.
