Best Cloud Access Security Brokers

Cloud Access Security Brokers (CASBs) are security enforcement points that ensure cloud app security by combining multiple security policies and providing visibility into cloud and SaaS deployments. As organizations increasingly adopt cloud services and employees access corporate networks from various devices and locations, CASBs have become essential for protecting against cloud security risks, ensuring compliance, and enforcing corporate security policies. By offering flexible solutions for authentication, encryption, malware detection, and more, CASBs help organizations secure access to cloud services, protect sensitive data, and defend against evolving threats in the cloud environment.

Key Points:

  • A Cloud Access Security Broker (CASB) is a security enforcement point positioned between enterprise users and cloud service providers.
  • CASBs combine multiple security policies, such as authentication, encryption, and malware detection, offering flexible solutions for cloud app security.
  • They protect against cloud security risks, ensure compliance with data privacy regulations, and enforce corporate security policies.
  • CASBs are increasingly important as employees use personal, unmanaged devices to access corporate networks from various locations, creating cloud security risks.
  • The concept of CASB emerged due to the need for consistent security across multiple cloud environments.
  • CASBs provide visibility into cloud and Software-as-a-Service (SaaS) deployments, protecting user and sensitive corporate data.
  • They offer protection against malware, phishing attacks, secure access to cloud services, and ensure cloud application security.
  • CASBs are crucial for organizations as the threat landscape evolves, with blended threats and obfuscation technologies making detection more difficult.

FAQs of Cloud Access Security Brokers

A CASB is a software tool that acts as a control point for cloud service usage in a company. It monitors and secures data and access between users and cloud applications.

It sits between users and the cloud, applying security policies to filter access, enforce rules like data encryption, and block unauthorized cloud use or downloads.

Cloud providers secure their own service, but a CASB protects at the organization level across multiple clouds, controlling data movement and access centrally.

CASBs guard against insecure cloud use, data loss or leaks, unauthorized cloud access, malware spread from cloud apps, regulatory violations and more.

No, it extends security rather than replacing traditional network security controls. CASBs protect cloud data and access specifically.

Yes, discovery of unknown “shadow IT” cloud apps being used in an organization is a key CASB capability to assess that risk exposure.
