Google Workspace™ DLP Best Practices for Businesses

Google Workspace™, formerly G Suite, is one of the most popular tools for collaborating on documents. Companies of all sizes are extensively using it. 

That’s why preventing data loss becomes one of the key tasks for companies’ IT security teams. Google Workspace™ DLP (Data Loss Prevention) tools can be of great help.

Organizations today that already have a presence in the public cloud must take Google Workspace™ security very seriously. The same seriousness applies to those looking to establish a public cloud presence in the near future.

Modern businesses with digital resources must be concerned with data security on-premises. 

The same concern applies to data in the public cloud. Google Workspace™ administrators must adhere to certain security best practices. This ensures the security of sensitive information and identity resources residing in the public cloud.

However, organizations must focus on data loss and data leak prevention, two key areas of Google Workspace™ (G Suite) security. These areas are crucial when it comes to protecting business-critical data in the public cloud. 

Losing or leaking business-critical data into the wrong hands can have severe consequences for an organization. This can result in both legal and financial repercussions.

Let’s explore these concerns in detail and outline actionable best practices for organizations using Google Workspace™.

Quick Summary

Businesses today depend heavily on SaaS platforms like Google Workspace™ to handle and store important data. However, it’s a common misconception that cloud providers fully protect this data from loss.

Because SaaS providers operate under a shared responsibility model, organizations remain responsible for protecting and backing up their own data.

Without a solid data loss prevention (DLP) approach, companies remain exposed to risks such as accidental deletion, ransomware attacks, insider activity, and configuration errors.

Key Takeaways from this Guide:

• Google Workspace™ data loss can occur due to human error, cyberattacks, SaaS application risks, or system vulnerabilities.
• Built-in protections are not enough to fully safeguard business-critical data.
• Cloud-to-cloud backups are essential for ensuring data can be recovered quickly and reliably.
• Ransomware protection should include detection, automated blocking, and file recovery capabilities.
• Strong access control and multi-factor authentication (MFA) help prevent unauthorized access.
• Monitoring user activity and deletion events improves visibility and response to threats.
• Controlling third-party SaaS applications and browser extensions reduces security risks.
• Data classification and sharing restrictions help prevent sensitive data leaks.
• Continuous monitoring, audits, and employee training strengthen overall data protection
• Using a dedicated solution like SpinOne helps automate backup, security, and recovery processes.

By implementing a well-structured Google Workspace™ DLP strategy, organizations can strengthen their data protection posture and ensure that business-critical data remains secure, accessible, and recoverable when needed.

What is Data Loss Prevention (DLP)?

Data Loss Prevention (DLP) is a set of tools, policies, and processes used to protect sensitive information from being lost, misused, or accessed by unauthorized individuals.

In Google Workspace™, DLP helps organizations safeguard important data such as financial records, intellectual property, and customer information while also providing visibility into how data is accessed, shared, and used. 

It plays a key role in reducing the risk of both accidental and intentional data exposure and supports compliance with regulations such as GDPR, HIPAA, and other data protection standards.

Data Loss Prevention is not a single feature but rather a combination of strategies that work together, including backups, access controls, monitoring, and threat detection.

Common Types of DLP

Understanding the different types of DLP helps organizations build a more complete and effective data protection strategy. 

Each type focuses on a different layer of the IT environment, ensuring that sensitive data is protected whether it is being transmitted, accessed on devices, or stored in the cloud.

1. Network DLP

Network DLP protects data as it moves across an organization’s network. It monitors traffic in real time to identify and block unauthorized transfers of sensitive information, such as emails containing confidential data or large file uploads to unapproved destinations.

2. Endpoint DLP

Endpoint DLP focuses on securing data on user devices such as laptops, desktops, and mobile phones. It helps prevent risky actions like copying sensitive files to USB drives, downloading data to unsecured devices, or sharing information through unapproved applications.

3. Cloud DLP

Cloud DLP is designed to protect data stored and shared within cloud platforms like Google Workspace™. It monitors user activity, file sharing, and permission settings to detect and prevent data leaks.

For organizations using Google Workspace™, cloud DLP is important because data is primarily stored and accessed in the cloud.

Data Loss Prevention for Google Workspace™: Best Practices

Google Workspace™ DLP is ultimately important for preventing the loss of business-critical data, which can be devastating for any organization. Data is the “new oil” of the digital world.

Businesses these days live and die by data or the lack of it. It is the lifeblood of today’s organizations living in a highly digital world. As mentioned, data loss is a tremendous concern for businesses, especially as they move to the public cloud.

Often, on-premise backup processes that protect data in private enterprise data centers don’t extend well to the public cloud. Intentional or accidental deletion of important data can create serious issues for organizations.

Data loss can occur due to intentional or accidental deletion. These deletions can be made by your employees or hackers who hijacked an account. 

Data loss can stem from a bug, or vulnerability exploit in SaaS applications that have access to your cloud data with editing permissions.

It can also result from the widespread malware of today, including the feared “ransomware” variants. 

These can render an organization’s data useless through the undetected encryption of files, folders, and more. Whether the data is lost due to deletion, a zero-day attack, or ransomware, all these scenarios pose significant risks of data loss.

Organizations must take the risks of data loss very seriously and ensure Google Workspace™ data loss prevention is in place.

Data breaches are becoming increasingly common and can result in sensitive information falling into the wrong hands. Using powerful cloud-based solutions, organizations must focus on the following best practices to prevent data loss:

1. Implement Effective Cloud-to-Cloud Backups

One of the most effective means and best practices of DLP for G Suite that is often overlooked is cloud-to-cloud backups. They can protect against accidental damage to data.

In fact, over 50% of data loss issues are the result of end-user mistakes. Backups also protect against intentional damage to data caused by a disgruntled employee or an attacker.

Organizations that are new to public cloud environments often incorrectly assume that public cloud vendors have robust backups of their data included in their storage plans.

Public cloud vendors do offer exceptional resiliency at the service level. However, organizations are ultimately responsible for their own data, particularly when it comes to data backups.

 By placing data in the public cloud, organizations must be ready to have an effective means of backing up business-critical data.

Backups of public cloud data are extremely important and involve:

• Automated backups of public cloud data
• During migration, the immediate backup of data
• Deletion control – Control who and what can delete data

2. Secure Data During Migration and Transfers

During migration to Google Workspace™ public cloud services, organizations are at risk of data loss if backups are not happening immediately. 

As soon as business-critical data lands in the Google Workspace™ public cloud environment, it needs to be protected. Make sure to have a solution in place before moving business-critical data.

Have a solution designed to begin backing up data once the Google Workspace™ (G Suite) data migration begins. This way, data is protected from both sides – both on-premise and in the Google Workspace™ public cloud.

The same rule applies when migrating data from another cloud environment, e.g., migrating from Microsoft 365 to Google Workspace™.

3. Monitor and Control Data Deletion

Organizations want to choose a solution to be able to monitor the deletion of files/folders across their Google Workspace™ environment. 

Data loss disasters can occur when admins don’t see the existing damage due to a lack of visibility into deleted data. Deleted data can then rotate off the retention policy of backups and become unrecoverable.

Organizations require a tool to clearly see and recover files or data in Google Workspace™ that might have been mistakenly or purposely deleted. This allows organizations to be proactive rather than reactive when it comes to data loss in the public cloud.

Deletion visibility can also help detect malicious user behavior. Upon investigation, a company can find out that such behavior is due to account hijacking, regular errors, or malicious intent.

4. Implement Ransomware Detection and Protection

Ransomware is one of the most serious threats to organizational data loss. Ransomware is a new type of malware variant that has gained tremendous popularity among attackers. 

Instead of simply damaging files, they are encrypted with an encryption key that only the attacker knows. The files are then held for “ransom” until the infected user provides payment, generally by anonymous currency such as Bitcoin.

Alphv, Cl0p 8Base, Rhysida, 3 AM, Malaslocker, BianLian, Play, Akira, and others have recently made headlines across the world, as business operations of large corporations have been brought to a halt with the above ransomware infecting cloud business-critical systems. New variants are developed each year.

Many have mistakenly thought that simply moving data to the public cloud, either Google Workspace™ or others, protects them from malware or specifically ransomware infections. However, this is not true. 

Often, public cloud data storage will utilize a synchronization process from on-premise workstations to public cloud data. If local copies of data are encrypted, these ultimately get synchronized to the public cloud as well.

Even if the company doesn’t synchronize with on-prem, modern ransomware strains can infect cloud environments. They work as regular SaaS applications with editing permissions and encrypt data in Google Drive™, Gmail™, and other Google services.

To force companies to pay the ransom, many modern ransomware attacks apply double or triple extortion techniques. The gangs copy the data before encrypting it. Next, they blackmail the company and company clients (data owners) to use the stolen information against them or sell it to other criminals.

An effective Ransomware Protection Solution provides:

• A Versioning System.
• Ransomware Detection.
• Automated Blocking of Encryption Processes.
• Automated Restore of Encrypted Files.

1. Ransomware Detection

An effective Google Workspace™ (G Suite) ransomware protection solution for public cloud data includes ransomware detection. This allows organizations to be alerted to suspected ransomware events as well as to be proactive, having the visibility they need to stop the attack. 

This helps mitigate the scope of the attack drastically, as in the case of data loss, by the time a ransomware event is detected, the damage has already been done.

The most efficient ransomware detection uses AI and ML to identify data behavior patterns consistent with a ransomware attack. They have the highest detection rate and the lowest number of false positive cases.

2. Automated Blocking of Encryption Processes

Aside from being alerted that a ransomware event is taking place, a truly effective ransomware protection solution would enable organizations to have an automated process to mitigate the attack in real-time as well. 

This includes blocking the attack source in real-time and being able to automatically identify the number of damaged files.

3. Automated Restore of Encrypted Files

An effective Google Workspace™ ransomware protection solution for public cloud data would also provide the ability to automatically restore encrypted files. Identifying file damage from ransomware, if done by hand, can be tedious work! 

Running a recovery process for those damaged files can be equally tedious. Having a solution that can automatically remediate ransomware infections can provide a powerful security mechanism for organizations moving data to the public cloud.

4. Versioning System

Should backups of public cloud data only include one version of your files/folders? A potent ransomware protection solution includes the ability to provide multiple versions of files and folders stored in the public cloud. 

This provides the ability to have multiple versions to revert to when it comes to restoring data. Google Workspace™ administrators want to have the ability to restore multiple versions of files if need be.

5. Control SaaS Applications and Browser Extensions

Modern SaaS applications and Chrome Browser Extensions have access to your Google Workspace™ data. Some of them have editing rights and can change your data automatically without your knowledge. One of the biggest issues with these applications is the lack of visibility and control over them.

Without special tools that control SaaS apps, GW users can freely sign up for various applications with their work accounts. As a result, a single organization can have hundreds of apps that have access to their data (with editing rights) and zero control from the security team.

As a result, the organization’s Google Workspace™ is prone to zero-day attacks, resulting in data losses and leaks.

What your business needs is an SSPM, a third-party tool to control SaaS apps and browser extensions. The key features to look for in such a tool include:

• Automated detection and risk assessment
• Allow- and blocklisting
• Automated remediation

6. Enforce Strong Access Control and Least Privilege

Limiting access to sensitive data is critical for preventing both accidental and intentional data loss.

Organizations should apply the principle of least privilege (PoLP), ensuring users only have access to the data necessary for their roles. Role-based access control (RBAC) and regular permission audits help reduce unnecessary exposure.

7. Enable Multi-Factor Authentication (MFA) Across All Accounts

Compromised accounts are a major cause of data breaches and data loss. Multi-factor authentication adds a layer of security beyond passwords.

By requiring users to verify their identity through multiple factors, organizations can significantly reduce the risk of unauthorized access to Google Workspace™ data.

8. Classify and Label Sensitive Data

Not all data carries the same level of risk. Classifying and labeling sensitive information helps organizations apply appropriate protection measures.

By identifying confidential and business-critical data, organizations can enforce stricter access controls, sharing policies, and monitoring.

9. Apply Data Sharing Restrictions and External Access Controls

Uncontrolled data sharing can lead to data leaks and compliance issues. Organizations should restrict external sharing, limit public link access, and enforce policies that prevent sensitive data from being shared outside the organization without proper authorization.

10. Establish Retention and Data Lifecycle Policies

Proper data lifecycle management helps reduce unnecessary data exposure and ensures compliance with regulatory requirements.

Organizations should define retention policies, automate data deletion where appropriate, and ensure critical data is retained and protected according to business needs.

11. Continuously Monitor User Activity and Detect Anomalies

Real-time monitoring is essential for identifying unusual or suspicious behavior.

By analyzing user activity, organizations can detect anomalies such as unusual login locations, abnormal file access, or mass downloads, allowing them to respond quickly to potential threats.
