Google Workspace (G Suite) Cloud App Security: Functions and Tools

Microsoft users can discover and assess more than 16,000 cloud apps with a native CASB solution—Microsoft Cloud App Security. But what about companies using G Suite (Google Workspace)?

Unfortunately, there is no similar native solution for G Suite, so these companies can look for alternative tools. In this article, we’ll analyze security functionality and tools that will help you secure your Google environment from app-related risks.

Key Functions of an Effective Google App Security 

To ensure Google Workspace Cloud App Security and meet compliance requirements, you’ll need a set of functions integrated with Google Workspace and its services (Gmail, Drive, etc.). Here are the key functions required to create an effective app security strategy. 

Cloud Access Management & Shadow IT Control

Employees can easily install an app or extension and grant access to sensitive data via OAuth. In many cases, such apps and extensions are not reviewed or permitted by IT teams. And this issue is more common than you might have thought.

According to Microsoft, 80% of employees use unapproved apps. This situation is known as Shadow IT – one of the biggest digital risks. 

The problem is that granting access to apps and browser extensions can expose your organization to security vulnerabilities, including malware infection or data leaks. To prevent such incidents, it is essential to have comprehensive visibility into the connected apps within your Google Workspace and address any identified security vulnerabilities.

This includes understanding their permissions and identifying the users associated with them. Also, access management includes monitoring user logins and sessions to spot abnormal activities and prevent unauthorized usage. 

While choosing a security tool for your apps, don’t forget to pay close attention to its app database. The higher is the total number of monitored apps, the better visibility a tool can provide for your Workspace domain. 

Risk Assessment & Threat Protection

After discovering all apps with access to your cloud data, you’ll need to decide how risky they are. In other words, perform a risk assessment to determine what their security and compliance risks are. 

The risk assessment will help you to reduce the probability of a security breach and protect your data from various digital threats (for example, ransomware 2.0). Implementing thorough risk assessment procedures and robust security measures is crucial for effective threat protection.

What are the specific tasks related to assessment? Here they are:

  • Creating a policy that defines the level of acceptable risk. 
  • Calculating risk score—an estimated measurement of all risks. Usually, the score is based on certificates, known vulnerabilities, patches, audit reports, user feedback, and many other factors.
  • Enforcing a policy via performing app whitelisting and blacklisting. These actions will ensure that risky apps are banned and acceptably safe ones are run and managed properly. 

Here is how app assessment works in practice:

Security and Compliance Management

Automating security processes to save time for SecOps specialists is vital. But there is another significant aspect of application security management —compliance. Compliance regulations and standards like GDPR, SOC2, ISO, and others require access management in place. 

If you fail to establish appropriate security controls for apps and allow data breach, you may face severe fines for compliance violations (more about the cost of non-compliance here).

Security and compliance management functionality is an essential concern, both for operational and regulatory reasons. That’s why you’ll need analytics, reports, and notifications. These tools allow you to plan and adjust your security management and, if needed, prepare yourself for a compliance audit.

App Security Tools

Usually, the functions mentioned above are provided by Cloud Access Security Brokers (CASBs). However, not all providers use this abbreviation to describe their services. So while researching tools, you’ll have to read about features carefully and decide how well they would fit into your workflow. 

Here are some of the best services that can help you with app security automation in your Google Workspace environment. 


SpinOne allows you to review over 60,000 apps and assess their security, compliance, and business risks. The discovered apps can be whitelisted/blacklisted based on your policies. Also, this solution provides visibility and control over data access, share, connected devices, and user behavior. Together with app security, SpinOne’s solution includes backup and ransomware protection.
