What Cloud Access Security Broker Software Companies do

Cloud Access Security Broker (CASB) Software is a critical cybersecurity solution that acts as a mediator between an organization’s on-premises infrastructure and cloud service providers. It provides visibility, data security, and compliance capabilities, enabling organizations to secure their cloud applications effectively while maintaining control over access and data usage. The primary use cases for CASB software include monitoring and managing access to sensitive data in cloud-based applications, enforcing security policies such as data loss prevention, and ensuring compliance with industry regulations. CASB solutions typically offer a range of features, including identity and access management, threat protection, data encryption, and activity monitoring. These tools facilitate the identification of unauthorized applications, also known as shadow IT, and allow businesses to govern their cloud usage based on user identity and roles. Common buyer personas include IT security professionals, compliance officers, and risk management teams, all of whom benefit from the enhanced visibility and control that CASB solutions provide in safeguarding cloud environments.
