The fundamental importance of the cloud access security brokers is increasingly being employed in data security on cloud computing software. As its demand and functionality are exponentially rising in the present years, it is important to understand the features that the CASBs provide.
Cloud access security brokers provide an essential IT support service to companies that are concerned with the security of data across different servers, whether on-premise or across remote locations. It provides deeper visibility into the dynamics of data access or transfer, the compliance policies, data security, and other threat vectors like malware.
CASB solution providers act as the control person that is placed between the users and the cloud software on which the data is stored and transferred. These days, businesses are increasingly investing in cloud software because of the larger availability of data storage space and easier access to data from different locations. Data loss prevention tool is one of the essential features that the CASB solution providers incorporate into their systems to provide a better data security system. CASB DLP solution has been defined as one of the strongest pillars of CASB.
DLP solutions, when integrated into the cloud access security brokers system, can efficiently check the data breach or leakage of confidential or sensitive data, which can cause a huge loss to the companies. DLP solutions can be customized accordingly by CASB solution providers. The configuration of the DLP solution can vary from one CASB to another to manage the cloud traffic or for ensuring the security of data. You need to look for these essential DLP capabilities extended by the CASB vendors.

Inspect Cloud Traffic From On-Premises, Other Devices, And Remote Users
The DLP capabilities of your CASB solution provider should be able to thoroughly inspect and fully cover the user’s location. The DLP solution should cover the cloud traffic across various devices. The user’s devices can be situated on the premise, or they can also access it from various remote locations. Usually, the CASBs cover only the on-premises cloud traffic, and they ignore the device situated in remote locations.
Inspect Cloud Traffic From Browser, Mobile App, Desktop App, And Sync Client
Apart from inspecting the servers located on-premise and the ones situated in some off-location, your DLP solution should also cover the cloud traffic generating from the web browsers, mobile apps, desktop apps, and sync clients. In most cases, the CASBs cover the obvious cloud traffic in the on-premise service while ignoring the web browsers, which can act as a serious perpetrator emanating the confidential data.
Inspect Content In And En Route To And From Sanctioned Cloud Services
The DLP solution of your CASB should also thoroughly scan the content which is stored extensively in the cloud services that are under sanctioned list. It should check the content that transfers through and from sanctioned cloud software. Enquiring such outflow of data regularly can check the end-points which is causing the data leakage in real-time.
Inspect Unsanctioned Cloud Traffic
Apart from applying the DLP capabilities to the sanctioned Cloud software, you also need to ensure that your DLP solution checks the cloud traffic on the unsanctioned cloud software. A major portion of the cloud storage is covered by the “shadow IT,” which does not fall under the domain of the centralized IT department. This can expose confidential data to unauthorized third party services.
Inspect All Types Of Leakages
The DLP solution of your CASB solution provider should check the content in the cloud services not only under the main domain, but the content in the different file types should also be inspected. This includes the different file extension changes, password-protected files, webmail or social media content, metadata, and the hidden data in various documents.
- Advanced Features For Accuracy And Precision
The DLP solution will also help you to detect the various kinds of false positives that can be imposed on your cloud traffic. It should also be able to deliver the services with greater accuracy and precision.
Support Accuracies With Contextual Policies
The right DLP solution of your CASB solution provider, apart from detecting the false positives in the cloud services, should also be able to support the various kind of contextual policies to strengthen the relationship between the user and the service providers.
Integrate With Existing Systems
The DLP solution of your CASBs will identify the already existing investments and will integrate the on-premises DLP with your prior investments.
To Conclude:
The DLP solutions of your CASBs extensively covers various functionalities to act as a pillar against the loss of data. You need to have a comprehensive understanding of the various DLP features that will help you to figure out the data loss. This will help your IT service provider to implement effective measures to secure the data on the cloud servers.
