A cloud access security broker (CASB) is a cybersecurity solution that safeguards cloud data. Acting as a security gatekeeper or checkpoint, it’s placed between business users and cloud services to enforce, validate, and manage data security measures and policies, such as data encryption, authentication, authorisation, and more.
CASB helps improve your organisation’s visibility into who has access to the cloud data and how it’s used. It combines threat monitoring, detection, prevention, and mitigation techniques to alert you about risks, so you can fix them in time and improve your security and cloud and SaaS compliance management.
