11 Best Cloud Access Security Broker Software (CASB) – 2024

Introduction :

The Cloud Access Security Broker serves as a gatekeeper for organizations, assisting them in keeping track of and safely utilizing cloud services while ensuring that network traffic complies with their security guidelines and standards.

Customers can see the use of cloud applications across various platforms due to these outstanding tools for data security.

Identifying the actors who pose a threat can stop a security breach threat.

CASBs use auto-discovery to determine the various risk factors that could have an impact on an organization as well as the currently in use cloud applications.

They safeguard organizations through firewalls, authentication, and data loss prevention and are made to be both vigilant and proactive.

Software-as-a-service (SaaS), platform-as-a-service (PaaS), and infrastructure-as-a-service (IaaS) environments are all compatible with a CASB’s capacity to address security flaws. 

Using CASBs (cloud access security brokers) is required to maintain visibility over data that has escaped the reach of on-premises tools due to the risk of data leakage in the cloud.

What are the four pillars of CASB?

Like a firewall, a Cloud Access Security Broker (CASB) enables an organization to extend security control outside its network boundaries.

The top analyst firm Gartner has divided the various CASB functionalities into 4 pillars, namely, 

Visibility	Using CASBs (cloud access security brokers) is required to maintain visibility over data that has escaped the reach of on-premises tools due to the risk of data leakage in the cloud.
Threat Protection	The CASB provides a variety of alerts that inform the IT department about threats discovered inside the business based on user behavior.
Data Security	CASB provides pre-built tools for monitoring access to cloud-based data storage. Various parameters, including location, IP address, browser, operating system, and device, can be controlled for access.
Compliance	Ignoring the issues can result in risky and expensive breaches, as these compliance standards are designed to ensure the safety of personal and corporate data.
