Best CASB Software Vendors for 2020
In the past, all the applications used by an organization reside in on-premise servers inside their data centers. IT departments can securely store company data and monitor its transmission. Later on, when companies started adopting cloud solutions, IT departments realized that employees are accessing services both approved and unapproved using devices issued by the company as well as their own. To address the security of data content stored in multiple places including the cloud, and data movement across users, devices, applications, and private and public networks, a cloud access security broker (CASB) has become a vital component of modern IT infrastructure.
What is a cloud access security broker (CASB)?
A CASB is a broker or intermediary between cloud users and cloud applications. These were previously network appliances, but today are software applications that are located inside the network or as cloud-native applications. Cloud access security broker can deliver management features only, such as monitoring and mitigation. Some offer CASB security only, which is prevention of high risk events. Some CASB tools offer multi-mode or a combination of security and management features. Cloud access security brokers can be deployed as an API-only tool or as a proxy, located between the user and the cloud.
Features and benefits of CASB
CASB solutions provide monitoring and management features to deliver specific benefits, also called the four pillars of cloud access security brokers:
- Visibility – provide comprehensive visibility into which cloud services are being used, who is using them, what is being sent or stored, and which policies are being followed.
- Compliance – provide reporting to determine the areas of highest risk in terms of compliance.
- Data security – enforce data security policies such as access control, sharing restriction, encryption, and enhanced authentication.
- Threat protection – with integration to other cybersecurity products, it can compile usage patterns and help detect and remediate theft and unauthorized access or block malware.
CASB software continues to add more capabilities as the number of cloud apps and ways to access them also continue to grow.
Best CASB software solutions & vendors for 2020
CASB vendors explain that cloud access security brokers are now essential in any modern cybersecurity strategy. They can help discover all cloud apps and resources used in the organization to spot shadow IT operations. Risky apps can be identified and access to them revoked. The best CASB can also help identify compromised user accounts while enforcing data loss prevention (DLP) policies to data in cloud apps. Here are our list of top CASB solutions in no particular order.
