What is Google Drive Encryption?

If your organization uses Google Workspace, chances are you store a wide range of data in the cloud—everything from employee information and financial records to proprietary industry knowledge and product details. With so much critical information at stake, securing your data is more important than ever, especially when working with multiple integrated SaaS applications.

Without proper protection, sensitive data can be exposed, putting both businesses and individuals at serious risk. In fact, 25% of sensitive data is publicly accessible, increasing the likelihood of identity theft, financial loss, reputational damage, and other irreversible consequences. In today’s digital world, strong security isn’t just a best practice—it’s a necessity.

In this guide, we’ll walk you through Google Drive’s Encryption features, its limitations, and how you can enhance your data security for maximum protection.

Why Google Drive Encryption Matters

What is Encryption?

Encryption is a cybersecurity technique that converts readable data into an unreadable format, ensuring that only authorized users with the correct decryption key can access it. This process protects sensitive information from unauthorized access, hackers, and data breaches.

What is Google Drive Encryption?

Google Drive Encryption refers to the security measures Google implements to protect files stored and shared within Google Drive. 

While standard encryption secures data across a multitude of assets, Google Drive Encryption specifically applies Google’s built-in encryption mechanisms to protect files in transit and at rest within Google Workspace. However, unlike end-to-end encryption (E2EE), where only the sender and recipient have access to the decryption keys, Google manages the encryption keys for Google Drive, meaning it has the ability to decrypt files if necessary.

How Google Drive Encryption Works

Encryption works by transforming plaintext data into cipher text using complex algorithms. Google Drive uses two primary types of encryption:

• Encryption in transit: Protects data as it moves between devices and Google’s cloud servers using TLS (Transport Layer Security).
• Encryption at rest: Safeguards stored data using AES-256 encryption on Google’s servers.

The Difference Between Standard Encryption and Google Drive Encryption

• Standard encryption (such as E2EE) ensures that only the data owner has access to decryption keys, preventing service providers from decrypting files.
• Google Drive Encryption, while robust, allows Google to manage the encryption keys, meaning files can be decrypted under certain circumstances, such as government requests or internal investigations.

Why Encryption is Essential for Cloud Storage

As cloud adoption grows, so do security risks. Without proper encryption, cloud-stored data is vulnerable to cyber threats, unauthorized access, and compliance failures. Here’s why encryption matters for cloud storage:

• Prevents unauthorized access: Ensures only approved users can view your files.
• Secures business-critical and personal data: Protects confidential information from exposure.
• Ensures compliance with data protection laws: Helps businesses meet regulatory requirements like GDPR, HIPAA, and SOC 2.

Google Drive’s encryption measures offer baseline protection and are suitable for most standard use cases. However, businesses dealing with sensitive data should consider additional security layers to ensure full control over their encrypted files, and get the coverage they need where Google Drive Encryption falls short.

How Does Google Drive Encryption Fall Short?

1. Google Controls the Encryption Keys

• Google retains key control: While Google encrypts data at rest and in transit, it retains control of the encryption keys, not the user.
• Potential for unauthorized decryption: Your domain administrator has control over which groups and individuals can use encryption. Applications on your computer with sufficient permissions granted, such as Chrome extensions, may be able to view and exfiltrate encrypted files.‍
• Why this is a problem: Even though Google encrypts the file, they don't provide visibility or control into the user who is sharing it, who they're sharing it with, and where the file is located. This creates a potential security and compliance risk, especially for businesses handling highly sensitive or regulated data. 

2. No Built-In End-to-End Encryption (E2EE)

• Encryption only happens after files reach Google’s servers: Files are not encrypted before leaving the user’s device.
• Exposure to interception risks: Without true E2EE, files could be accessed in transit before encryption is applied.
• Why this is a problem: Files could be intercepted or accessed before encryption takes place. Businesses handling confidential data may require stronger encryption measures than what Google offers.

3. Lack of Granular Access Controls for Encrypted Files

• Encryption is not tied to user-specific access rights: Once a user has access to a file, they can view it in an unencrypted state.
• No dynamic access management: Google Drive lacks adaptive policies that adjust encryption access based on user behavior or security risk level.
• Why this is a problem: Misconfigured permissions, compromised accounts, or malicious insiders can lead to unauthorized data exposure.

4. Compliance Risks & Regulatory Gaps

• Does not meet all industry-specific compliance needs: While Google Drive adheres to general security standards, some industries require stricter encryption policies.
• Lack of customer-managed encryption keys (CMEK): Many businesses require direct control over encryption keys to meet compliance requirements, which Google does not natively provide.
• Why this is a problem: Google’s default encryption model does not align with zero-trust security frameworks required by highly regulated industries like healthcare, finance, and legal sectors.
  

5. Vulnerability to Insider Threats & Google Access

• Google employees can access encryption keys: Under certain circumstances, Google personnel have the ability to decrypt and access user data.
• Risk of internal misuse: Organizations face the risk of insider threats where employees exploit their access privileges to expose or share sensitive information.
• Why this is a problem:  Google Drive lacks native monitoring tools to detect and prevent unauthorized insider access, leaving organizations without built-in insider threat protection. Additionally, sensitive files may still be at risk of external or public exposure. Even if encrypted in transit, a file could be shared with former employees, external vendors, or third parties who no longer have authorized access. Worse, if file-sharing settings allow public access, anyone with the link—regardless of encryption—can open the file.

DoControl: Filling in the Gaps of Google Drive Encryption

1. DoControl Ensures Full Visibility and Control Over Who is Accessing Your Encryption Codes 

One of the biggest limitations of Google Drive encryption is that Google retains control over encryption keys, meaning that Google—and potentially any entity with access to its infrastructure—can decrypt and access your files if needed. 

This creates a significant security and compliance risk, especially for businesses handling highly sensitive or regulated data. Without clear visibility into who is accessing encrypted files and when, organizations are left vulnerable to insider threats, unauthorized access, and data exposure.

DoControl eliminates this blind spot by providing full visibility into your SaaS environment, ensuring that only the right people have access to your encrypted data. Unlike Google’s default encryption, which lacks granular access insights, DoControl enables businesses to:

• Instantly build an inventory of all SaaS application assets, users, and third-party OAuth apps, ensuring no unauthorized access goes undetected.

• Quickly uncover data exposure by running targeted queries that show who viewed files, when, and what actions they took.

• Gain a centralized operational view of all main risks, recent alerts, and remediation actions across SaaS applications—not just Google Drive.

With DoControl, businesses gain complete oversight and control over their encryption security, ensuring that files remain protected from both internal and external threats.‍

2. DoControl has Automated Workflows to Seamlessly Manage Granular Access Controls for Encrypted Files

Google Drive provides basic access controls, but its encryption is not tied to user-specific access rights. This means that once a user has permission to access a file, they can view it in an unencrypted state—leaving organizations vulnerable to insider threats, compromised accounts, and misconfigured permissions that could expose sensitive data. 

Google Drive lacks dynamic, automated enforcement, requiring security teams to manually monitor and adjust permissions—a process that is both inefficient and prone to human error.

DoControl solves this challenge by offering granular, automated access controls that adapt to your organization’s needs. With policy-driven workflows, DoControl ensures that encryption security is continuously enforced without disrupting business operations. Key benefits include:

• Conditional-logic remediation workflows that enable automated policy enforcement across SaaS applications with minimal effort from security teams.

3. DoControl Eliminates Insider Threat Risks and Prevents Unauthorized Access

One of the most significant risks to data security is insider threats—employees who misuse access privileges, either intentionally or unintentionally, to share or leak sensitive company data. 

While Google Drive offers basic encryption and access controls, it does not provide real-time monitoring or contextual risk assessments to detect and prevent insider threats before they cause harm. Businesses handling highly sensitive data need a more proactive approach to securing their information.

DoControl goes beyond standard encryption by leveraging machine learning and real-time monitoring to detect and stop insider threats before they escalate. Key features include:

• Real-time scanning with NLP to identify sensitive data types—including PII, PHI, PCI, secrets, and credentials—minimizing false positives by using custom keywords, RegEx, and business context from identity providers (IdP), endpoint detection and response (EDR), and human resources information systems (HRIS).
• Proactive insider threat detection using ML algorithms to identify risky user behavior, such as employees sharing multiple assets before leaving the company or sensitive data being transferred to personal accounts.

• Real-time alerts and automated responses sent directly to security teams via email, Slack, or SIEM integrations, allowing for immediate remediation of suspicious activity before data is exposed.

By combining user-level visibility, contextual risk scoring, and real-time anomaly detection, DoControl ensures that organizations can quickly identify and prevent unauthorized access—protecting sensitive business and customer data from both internal and external threats.

4. DoControl Enables You to Monitor Threats 24/7 and Bulk Remediate When Necessary

Google Drive Encryption offers a foundational layer of security, but it falls short in threat monitoring and large-scale remediation. It lacks native capabilities to continuously track suspicious activity, enforce proactive security measures that consider business context from other data sources, or efficiently address and remediate security risks such as exposed encryption keys, misconfigured file permissions, and unauthorized access at scale.

Organizations need a comprehensive approach to identity threat detection and response (ITDR) that goes beyond Google Drive’s standard security features.

DoControl delivers continuous monitoring and bulk remediation to help organizations stay ahead of security threats and enforce real-time access governance. Key capabilities include:

• Assess identity risk in real time by collecting and analyzing data access patterns, user permissions, and business context from HRIS to dynamically determine who should have access to what and flag high-risk behavior.
• Empower employees with self-remediation through an automated Slack bot that engages users directly, allowing them to correct risky file-sharing actions in real time without requiring IT or security team intervention.

• Execute bulk remediation at scale by instantly revoking access to up to a million files with a single click of a button, eliminating the need for manual cleanup efforts that could take weeks or months.

By combining automated monitoring, real-time identity risk assessment, and bulk remediation capabilities, DoControl enables organizations to proactively secure their SaaS environments, ensuring that threats are identified and mitigated before they lead to data exposure.
