Google Workspace (formerly G Suite) is a vital part of many companies’ workflow. Every company needs to have a clear picture of how their data is accessed, shared (including sharing outside/in violation of policies), and protected from digital threats. Using CASB is a way to address these issues. But what, exactly, is CASB, and why is it essential for your security strategy? Let’s find out.

What Is G Suite CASB?
CASB, or cloud access security brokers, are intermediaries between users and cloud services. These intermediaries help to enforce your company’s security policies that cover cloud access.
CASBs help to implement security policies and their elements, including authentication, login monitoring, sensitive data access, application assessment, data sharing, insider threat control, and many others.
Though having an intermediary may look like an overcomplication, the situation is quite the opposite. CASBs do not just serve as an additional layer of protection but also as a way to simplify and automate your security processes.
Why Do You Need Cloud Access Security?
Using CASB services allows companies to improve visibility and control over their cloud data and automate some of the essential IT security tasks. For an enterprise environment, CASBs are a way to improve efficiency. For SMBs, using a CASB is an even greater solution, as CASB services are more affordable than hiring a big IT security specialist team. Here are some of the major cloud access issues CASBs help you with.
Risky SaaS Application and Shadow IT
Often, your employees install and use apps and extensions without notifying managers/administrators, which may lead to data breaches. Such usage is known as Shadow IT. Though apps can improve workflow and user experience, the potential risks should be kept in mind.
It’s critical to monitor all SaaS apps connected to your cloud and having access to your documents, emails, or photos. If installed without proper procedures, SaaS apps could lead to data loss, malware infection, or unauthorized access.
However, even approved apps may pose significant security and compliance risks. Hackers can exploit app vulnerabilities and access all data an app is connected to. Long story short, every company must be fully aware of all SaaS apps with access to corporate data (even the approved ones) and their potential risks.
Ransomware is one of the fastest-growing threats from cloud environments. Hackers use this type of malicious software to seize cloud data and force companies to pay ($178,254, on average) to release their data back. Apart from being held to ransom, companies have to face downtime costs, reputational damages, and other unpleasant consequences.
SaaS apps serve as one of the sources of ransomware infections. Some apps, due to security vulnerabilities or malicious intent, can bring ransomware into your cloud. By giving permissions to potentially dangerous apps, you allow hackers to access your cloud data and encrypt it. Protecting cloud data access helps companies prevent ransomware attacks, which is better than facing the consequences of an attack

As we’ve mentioned above, using various apps and extensions may result in unauthorized access to your data or data loss. Such incidents harm companies directly and lead to compliance violations and, accordingly, fines. So companies should always protect themselves from data breaches, even if the reason behind a breach is a third-party app.
CASBs can help your company to safeguard its critical data and address regulations such as HIPAA, GDPR, CCPA, and others. How exactly? CASBs will help to identify potential security gaps that can lead to unauthorized access to your cloud data.
Proxy-based and API-based CASBs
CASBs can be divided into two major categories: proxy-based and API-based. What is the difference? Proxy-based CASBs form a single stand-alone gateway that monitors the traffic between your users and the cloud. API-based solutions use APIs to connect users and cloud services.
Why do we believe that the API-based approach is more efficient? This approach scales well and allows for a connection between users and the cloud without introducing unnecessary latency.
Also, proxy-based CASBs do not address Shadow IT issues as efficiently as API-based solutions. Why? The API solutions are integrated with cloud infrastructure, which allows them to oversee both managed and unmanaged data traffic.
