How to Choose the Best CASB Vendor

What is a CASB?

Cloud Access Security Broker (CASB) solutions extend corporate security policies into the cloud, helping you to protect sensitive business data while using SaaS, IaaS, and PaaS products.

CASBs scan traffic between enterprise users and cloud platforms, delivering four main functions:

• Visibility into the cloud services in use across an organization to assess the risk of data being exposed from misconfigured or unsafe, unsanctioned applications (shadow IT).

• Data Security programs for cloud environments, including access controls, data loss prevention (DLP) measures, encryption, and quarantining.

• Threat Protection technologies (e.g., malware detection, browser isolation, URL filtering, etc.) to identify and block malicious activity or compromised accounts.
• Compliance and adherence to data protection regulations, even when using cloud applications and storage.
