What is a Cloud Access Security Broker (CASB)?

A cloud access security broker (CASB) is a tool or service that regulates an organization's and cloud provider’s policies.

Security

CASB security controls address cloud service risks, identify high-risk applications and enforce security and compliance regulations in IaaS platforms such as AWS, Azure, and Google Cloud.

Compliance

By ensuring that network traffic between on-premise devices and the cloud provider comply with the organization's security policies, CASBs, and similar services, help organizations extend the security controls of their on-premise infrastructure to the cloud.

Visibility and Monitoring

CASBs are particularly useful in organizations with shadow IT operations or liberal security policies. When multiple departments manage their own cloud resources, it is essential for security teams to maintain security and monitor cloud service usage.

The Challenge of the Cloud

With the rise of BYOD devices and multiple access points, users are now able to access unapproved cloud services and even mishandle business data in approved ones.

Shared Responsibility

Cloud service providers only manage the security of the cloud infrastructure. They do not secure the connections to that environment, meaning businesses are responsible for everything that is in the cloud. Because of this model, experts have predicted that for the next few years, the majority of cloud security failures will be caused by the customer, rather than the cloud security provider.

Shadow IT

Users often access “shadow IT” that eludes security policies - such as cloud services that are acquired by individual departments and not shared with the IT team. CASBs in enterprises allow IT departments to mitigate these new risks introduced by varying cloud services.

Security Control

CASB allows IT to take back control of these free reigning processes by enabling IT departments to monitor the usage of cloud services and implement centralized controls to ensure security practices are followed.

Top CASB Use Cases

With comprehensive integrations, CASBs can ensure your environment remains protected even with progressively intelligent attacks.

Monitor Usage & Permissions

Instead of taking a coarse-grained approach and blocking services, the best way to monitor activities is through granular visibility and control. This allows you to define policies and govern usage based on identity, service, activity and data. With a CASB, or similar security service, you can determine service categories and risks, enforce policies such as alerting, quarantining, bypassing and more.

Securing a Digital Workspace

SDPs protect networks and critical assets from external threats.

Visibility

To control access in sanctioned and unsanctioned services, businesses need full visibility into their cloud environments. A CASB allows businesses to govern access, activities and data within the cloud,report on cloud spending, and identify redundancies in functionality and license costs.

Threat Protection

Organizations need to ensure their employees aren’t introducing malware and other threats through outside clients and services. With threat intelligence, malware analysis and threat remediation, detection of insider threats, unauthorized user threats and comprised accounts are all managed.

Data Security

By enforcing data-centric security and reducing the detection surface area according to user, location, activity, and other identifying data. Further security implementations include encryption tokenization, access control, and information insights and management.

Compliance

Compliance regulations are designed to ensure the safety and privacy of corporate data. Cloud brokers ensure data resiliency and cloud compliance in coordination with your organization's policy requirements.
