What is Google Workspace for SMBs

Google Workspace provides cloud-based productivity tools, including Gmail, Drive, Docs and Meet for small and medium businesses. The platform combines email hosting, file storage and collaboration features in a unified environment that teams can access from any device. The subscription-based model scales with business growth while maintaining consistent security policies across all user accounts and organizational units.

Basics for securing your Google Workspace environment

Strong authentication is the foundation of Google Workspace security by preventing unauthorized access to business accounts. You can also manage over-shared resources and protect sensitive company data from accidental exposure or malicious access. Threat monitoring through Google’s built-in tools can provide early warning of potential security incidents before they impact business operations. These security layers work together to create a defense strategy that addresses the most common attack vectors targeting cloud-based business environments.

Enforce 2-step verification

You can mandate 2-step verification across your organization through the Google Admin console. Consider these implementation steps to activate organization-wide protection:

1. Access the Google Admin console and navigate to Security > 2-Step Verification.
2. Select “Enforcement” and choose “On for all users” from the dropdown menu.
3. Set the enforcement date to allow users adequate time to set up their authentication methods.
4. Configure backup verification methods, including backup codes and alternative phone numbers.
5. Test the configuration with a pilot group before rolling out to the entire organization.
6. Communicate the changes to users with clear instructions for setting up their devices.
7. Monitor adoption rates through the Admin console reporting dashboard to identify users who need additional support.

Authenticate Email Domains (SPF, DKIM, DMARC)

Phishing and domain spoofing remain primary vectors for account compromise. Enforcing email authentication ensures attackers cannot impersonate your client’s domain to trick internal employees or clients.

• Configure SPF (Sender Policy Framework) records in DNS to list authorized sending servers.
• Enable DKIM (DomainKeys Identified Mail) in Admin console > Apps > Google Workspace > Gmail > Authenticate email to digitally sign outgoing messages.
• Set up a DMARC policy (TXT record in DNS) starting at p=none to monitor traffic, gradually moving to p=quarantine or p=reject to block unauthorized emails.

Manage shared drives as admin

When it comes to managing shared drives, permission management is key to preventing data leaks while maintaining effective collaboration. You should create drives with specific business purposes and assign appropriate access levels to team members. Regular audits of shared drive permissions will help you identify and remove unnecessary access that accumulates over time. Drive-level permissions override individual file permissions, making it essential to establish clear naming conventions and access hierarchies from the start.

Use the Alert Center for threats

The Google Workspace Alert Center provides real-time notifications about security incidents and suspicious activities. This allows you to receive alerts for malware detection, suspicious login attempts and data loss prevention (DLP) violations. Setting up proper alert routing helps your security team to respond quickly to potential threats before they escalate into major incidents. Custom alert rules can be configured to match specific organizational risk profiles and compliance requirements.

Core Google Workspace Security Practices

Strengthen Google Workspace security

You can use advanced security measures to enhance these basic protections and create multiple layers of defense against sophisticated attacks. Access controls, for instance, limit user permissions to only what they need for their job functions. Activity monitoring and app permission reviews can help identify potential security gaps before they become problems.

All of these security features provide granular control over data access and user behavior across your Google Workspace environment.

Set up access controls

Organizational units allow you to apply different security policies based on user roles and departments. Context-aware access policies can restrict sensitive data access based on device compliance and location.

Licensing Note: Context-Aware Access (CAA) controls require Google Workspace Enterprise editions or Cloud Identity Premium add-on licenses. For SMBs on Business Starter or Business Standard plans, enforce device controls via Google Endpoint Management instead.

Follow these steps to implement granular access controls:

1. Create organizational units in the Admin console under Directory > Organizational units.
2. Move users into appropriate organizational units based on their job functions and security requirements.
3. Configure context-aware access policies under Security > Access and data control > Context-aware access.
4. Set device management requirements, including screen locks and encryption for mobile devices.
5. Implement location-based restrictions for users who access sensitive data remotely.
6. Test access policies with different user scenarios to verify they work as intended.
7. Document policy exceptions and approval processes for users who need elevated access permissions.

Monitor user activity

User activity reports reveal patterns that might indicate compromised accounts or insider threats. The Admin console provides detailed logs of file sharing, email activity and login patterns across the organization. Regular review of these reports helps spot unusual behavior before it leads to data breaches. Automated reporting tools can generate weekly summaries of high-risk activities and flag accounts that exceed normal usage patterns.

Review app permissions

Third-party applications connected to Google Workspace can access significant amounts of business data. You must regularly audit which apps have access to organizational data and what permissions they hold. Removing unused or suspicious applications reduces the attack surface and protects against data exfiltration through compromised third-party services. App permission reviews should include both organization-wide installations and individual user connections to external services.

Restrict OAuth App Access

Prevent “consent phishing”—an attack vector where users inadvertently grant malicious or unauthorized third-party applications broad access to their Google Drive files, Gmail contents, or Contacts.

1. Navigate to API Controls: In the Google Admin console, go to Security > Access and data control > API controls.
2. Access App Settings: Click Manage Third-Party App Access.
3. Restrict Unconfigured Apps: Under Unconfigured app settings, change the default access level to Restricted. This ensures any new, unapproved third-party apps cannot access restricted Google Workspace APIs without admin approval.
4. Review Pending Requests: Regularly check Apps pending review to approve or deny user access requests for third-party tools.
5. Audit Inactive Access: Periodically review the Accessed apps list and revoke OAuth tokens for applications that have been inactive for over 90 days.

Integrate using Microsoft security tools

Many organizations run mixed environments with both Google Workspace and Microsoft technologies. BitLocker encryption protects local device storage even when users access cloud-based Google services. Using PowerShell commands helps you quickly verify the encryption status of Windows devices across the organization. Using a hybrid approach enables you to maintain your existing Windows infrastructure while securely leveraging Google’s cloud productivity tools.

Use BitLocker for device encryption

BitLocker encryption protects data stored locally on Windows devices that access your Google Workspace environment. Full disk encryption prevents unauthorized access to cached files and offline data. A best practice is to enable BitLocker on all Windows devices that connect to Google Workspace services. The encryption works seamlessly with Google’s cloud services while providing additional protection for locally stored business information and cached authentication tokens.

Get-BitLockerVolume with PowerShell

You can use PowerShell commands to automatically check the BitLocker status across multiple devices in the organization. The Get-BitLockerVolume cmdlet returns encryption status and protection methods for each drive.

Consider these steps to verify your BitLocker deployment:

1. Open PowerShell as Administrator on the target Windows device.
2. Run Get-BitLockerVolume to display encryption status for all drives.
3. Check that the “VolumeStatus” shows “FullyEncrypted” for the system drive.
4. Verify that “KeyProtector” includes TPM or TPM+PIN for automatic unlocking.
5. Document any drives showing “FullyDecrypted” status for remediation.
6. Create scripts to run these checks across multiple devices remotely.
7. Generate compliance reports that track encryption status across the entire device fleet.

Align Windows Server policies

Group Policy settings on Windows Server can enforce security requirements for devices accessing Google Workspace. By applying password complexity rules and screen lock policies, you can extend Google’s authentication controls to endpoints, creating a consistent layer of protection. When these policies are coordinated, you maintain uniform security standards across both cloud and on-premises resources. With Active Directory integrated into Google Workspace, you also gain centralized user management and unified policy enforcement across your hybrid environment.

Maintain ongoing Google Workspace security

Security requires continuous attention rather than a one-time setup to remain effective against evolving threats. Keeping your policy up to date can help you adapt your security posture to changing business needs and threat landscapes. Ongoing maintenance also helps secure your Google Workspace environment as business requirements and security threats continue to evolve.

Policy updates should reflect changes in business processes, compliance requirements and emerging security threats that could impact the organization. Change management processes help track policy modifications and their impact on user productivity and security effectiveness.
