FAQs

What Are CASB Solutions?

CASB (Cloud Application Security Broker) solutions are a security tool which enable organizations to manage and secure their cloud applications, such as Microsoft 365 and Salesforce. These applications can quickly become vital to an organization, running key tasks and processes. But as they sit outside of your own network, it can be difficult to manage data, access policies, and tracking how many different applications are actually in use.

CASB solutions mitigate against these issues by providing a unified admin console connected to cloud applications and services which provides oversight and additional layers of security controls. This includes threat detection capabilities, user activity monitoring, policies and reporting and more. Capabilities of specific solutions can vary, some are integrated into wider web security solutions, some into endpoint and device security services, providing holistic security across an organization’s network.

CASB solutions are also important tools to prevent data loss. Many solutions provide data loss protection policies, access management and auditing to track where data is stored, and who has access to it. This is important to prevent data breach, but also to ensure compliance requirements are met, and best practices are enforced.

How Do CASB Solutions Work?

Cloud Access Security Brokers (CASBs) are security tools that sit between users and cloud-based applications, enforcing security policies and security controls. These services secure data moving from your local network environment to the cloud and vice-versa, based on your security policies such as encryption and authentication.

CASBs help to prevent, monitor, and mitigate against cybersecurity risks. Many solutions offer alerting for malicious activity or potential compliance violations, to help security teams keep on top of cloud risks. They can be used to help detect threats like ransomware, as well as preventing cloud-based account compromise by enforcing security policies such as single-sign on and device profiling.

CASBs are commonly deployed via Proxy Deployment, sitting between users and the SaaS cloud application, or via API deployment.
