Cloud Access Security Brokers are truly useful in today’s cloud-driven world, where enterprises are looking to secure their data over cloud-based devices. Ubiquitous cloud adoption majorly, including cloud applications like Office 365 and the consequent cloud data security concerns, is all leading to the growing popularity of CASB vendors in all major industry verticals, from finance to telecom, from healthcare to trading, etc. Like many other enterprises, if you have also decided to fetch a CASB solution to help your organization, then you need to compare CASB vendors and then choose the best-suited one. The following are the essential questions to ask while evaluating CASB vendors.

How the CASB solution differs from the in-built cloud app security?

Every cloud application vendor would make his own decision on which type of security functionality has to be built into their provided application. One application might include a kind of security function while missing out on some other feature. Another such use might offer just the opposite of what the first one was offering. So, there is quite a variety! While you compare CASB solutions, ensure that the chosen CASB vendor offers some value more than the available built-in security.

Do CASB Solutions Impart End-to-End Protection for Cloud-Based Data?

Cloud-based data is not only there in the cloud; the moment it is deployed, users arrive with several devices and begin downloading massive amounts of data onto these devices across the cloud. In no time, as the cloud apps can be accessed through mobiles, the problem can escalate into a data breach issue from a mobile device. So, the organizations need to keep an eye on the sharing of confidential data from mobile devices to prevent any leakage and not only the data on Cloud needs to be kept under surveillance.

Is It Possible to Implement CASB Access Control Over Both Unmanaged and Managed Devices at the Same Time?

The access from a mobile device or unmanaged device is more prone to data leakage over the devices configured over the cloud network. Thus, any CASB solution is best qualified to be an application to host when it can take absolute control over both managed and unmanaged devices to prevent any leakage. Organizations, though, don’t seek their data through mobile devices, but at times, the situation and the nature of the assignments force them to push their data through unmanaged devices. A best CASB solution thus must achieve both the tasks of mobile security as well as data access through a vast cloud network.

Check If the CASB Solution of Your Liking Can Provide Real-Time Visibility and Control?

Even a minute length of unauthenticated data exposure may lead you into losses. So, you must guard against any data leak even when your cloud network devices are off-line due to connectivity issues. A CASB solution is foolproof only when it can provide real-time visibility and control of data, and checks any unwanted or unauthenticated exposures of confidential data for any length of time. An API based CASB solution too can lead to the disclosure of sensitive data due to inadvertent notifications delays that come along with APIs for periods where often cloud data remains unguarded and unchecked. Thus, a hybrid approach CASB solution is best suited, which uses both API based and proxy approaches to ensure complete data protection.

Does CASB Solutions Protect Unauthorized Data Access?

Transparency in the system by gaining visibility into data access activities, so that suspicious activity is reported does prove very helpful. Still, with conventional security models, it is rather too late to act. For being proactive against such unauthorized data access, there is something that only a CASB solution with integrated IAM or identity management can provide. So to detect any users logged on into the same app from 2 different locations at the same time, it is always better if a CASB solution can step-up for multifactor-authentication on both of those devices soon after that rogue session is attempted.

Startups, small businesses, as well as medium businesses, can ensure their enterprise security by deploying an effective CASB solution by having better data security handle over their cloud-procured data.

Why should businesses use a CASB?

CASB is currently a necessary bit of any organization’s cybersecurity framework. Organizations utilizing cloud applications for efficiency, coordinated effort, and capacity inevitably undergo a certain set of challenges for working in the cloud. Using CASB resolves vast numbers of these difficulties by giving unequaled security, visibility, and command over access to conduct cloud applications.

Over a while, CASB has been able to successfully resolve security issues that enterprises are encountering while storing their data on cloud computing. This article will discuss in detail the significant challenges which CASB has addressed.

Organizational Benefits of CASB Implementation

  1. If the enterprise is in possession of bulk confidential data like law firms and finance corporations, then availing a feature that allows granular control of data is highly significant to them. CASB solutions provide the best practices like absolute control over data sharing and downloading by users over the cloud, restricting access to limited groups or individuals, and guarding against data duplication.
  2. CASB solutions also offer setting up permissions of documents and ensure keeping them protected at all times.
  3. Monitoring the traffic from on-premises to cloud services can help the enterprises to keep a check on the policy violations, using Shadow IT features.
  4. Enterprise mobility is aided by the CASB solutions. They provide data security when downloading sensitive data from the cloud storage to personal devices like mobiles etc.
