CASB solution checks and filters cloud access traffic. It comprehensively checks the data to devise suitable network security solutions.

1. 8 Major Facts You Must Know Before
You Buying A CASB

3. Cloud Access Security Brokers or CASBs are gaining imminent popularity in the IT sector. CASB vendors
provide enhanced solutions to manage the encryption and authentication of data in cloud applications or
services. Cloud-based software is essentially a shared platform, and hence the sensitive data stored in it is
exposed to potential cyber threats. Modern-day cybercriminals can hack into the cloud collaboration platform to
steal confidential files or documents. CASBs give you deeper visibility into the cloud operation. CASB solutions
allow you to monitor and control the transfer, management, storage, and retrieval of data on cloud servers.
Before the CASB solution was introduced to the IT world, enterprise security managers had minimal visibility
into the cloud data. However, in recent times CASB is used to address the gaps in data security across
software-as-a-service (SaaS), platform-as-a-service (PaaS), and infrastructure-as-a-service (IaaS)
environments. The exponential growth of the CASBs directly affects their ability to secure data across all the
endpoints. According to the studies which analyze the global cloud access security broker (CASB) application
market status CASB market is projected to grow from USD 8941.1 million to USD 36910 million by 2026 with a
CAGR of 22.2%.
CASB solution providers deliver security features across multiple clouds on various platforms. SaaS solutions
require constant monitoring to secure user privacy and corporate data in subscription-based cloud applications.
This ensures that unauthorized third-party sources do not access sensitive data. CASBs can actively check the
data breach in real-time and passes on the information to the system administrators to eliminate the potential
threats.
If you want to purchase a CASB solution, you need to follow the listed steps to make the right choice.
1. You need to primarily curate a list of the applications and software you want to integrate with your CASB
project. This is a minimal requirement to initiate the integration process. You can check the CASB solution’s
functionality within this range of applications before you widen its scope.

4. 2. To deploythe CASB solution, identify if you want to integrate the solution with other existing services,like
the identity-as-a-service (IDaaS)/single sign-on (SSO) tools.
3. Authentication of the cloud access process should notbe based on the simple binary of “yes” or “no.” A
deeperunderstanding of integration that involves a comprehensive understanding of how and when you
should incorporate the complexrisk-based authentication will improve the data security process.You need
to determine if you want to merge your CASB solution into this authentication process.
4. Identifying the if’s and how’s of the field-leveldata encryption and authentication that your productwill
supportis essential.
5. Check out the multimode CASBs.Amultimode deployment(aka traffic steering)CASB solution gives you
the flexibility to cover several use cases.It also makes sure that you understand the limitations of the
productin the various operating modes.
6. Identifyif the products integrate seamlesslywith the existing security systems,be it web gateways,
application firewalls, DLP tools, and email providers.Thoroughly examine the CASB solution to check if it
offersadvanced solutions compared to what you already have installed in your company.
7. Determining the budgetfor your CASB solution is essential. You need to get an estimate of the costs the
solution will incur. Check the annual costfor simple installations of a few cloud apps instead of extensive
coverage formultimode unlimited cloud apps.Ask your team what will suit your business requirements
better.
8. You also need to ensure that the CASB solution is compliant with your company’s enterprise protocols for
stable and durable compatibility.

5. Multiple Use Cases ofCASB
Secure Shadow IT
CASB solution is deployed by the companies to identify, monitor, and secure the shadow IT. Shadow IT
involves hardware, software, application, and network servers that are not managed by the organisation’s
centralized IT team. Shadow IT does not necessarily adhere to the security, compliance,and governance
policies of the organizations. CASB’s solution protects the company’s data by blocking the access of the cloud
data by any unauthorized apps.
GovernDeviceUsage
Another critical use case of CASBs is to monitor the user activity thoroughly. Hence, access to cloud data is
checked across various platforms.This helps to detectand prevent fraudulent activities in the cloud in real-
time.
SecureData
CASBs protects the data from exfiltration. Hence, it checks if the data is being transferred from sanctioned to
unsanctioned cloud software. CASB solutions enforce various policies which are compliant with the
organizations. This solution enforces conditionalactivity-level policies to apply the appropriate encryption to
the corporate data.

6. Block Malware
CASBs acts as a firewall to protectcloud applications from malware attacks. It detects and alerts
organizations about suspicious logins, excessive downloads,uploads,or unauthorized file sharing.
To Conclude:
CASB solution checks and filters cloud access traffic.It comprehensivelychecks the data to devise
suitable network security solutions.This helps organizations gain deepervisibility into the transfer, storage,
management, and access of data on cloud collaborationplatforms.
