IT Security Guideline for SMBs Using Google Workspace (Under 100 Users)

IT Security Guideline for SMBs Using Google Workspace (Under 100 Users)

For SMBs in Thailand, Google Workspace is one of the most well-known solutions for businesses, powering email, collaboration, and cloud storage in daily operations.

As your business expands, security risks increase. Even if your organization has fewer than 100 users, you can still achieve enterprise-level security with the right setup and discipline.

How can businesses improve IT security in the organization?

1. Strengthen Identity and Access Management

  • Enable 2-Step Verification (MFA) for all accounts.
  • Turn off Less Secure App Access in the Admin console.
  • Assign roles properly and clearly – Admin rights only for IT or management.
  • Always check Security Reports in the Admin console for suspicious logins or failed attempts.
  • Disable or suspend unused accounts immediately.

2. Protect Endpoints and Devices

  • Require all company devices to sign in with Google Workspace accounts and manage through Device Management.
  • Enforce screen locks, encryption, and automatic OS updates.
  • Use Basic Mobile Management to remove lost devices.

3. Secure Data and File Sharing

  • Use default sharing as ā€œRestrictedā€ for internal use only.
  • Enable Data Loss Prevention (DLP) in Drive and Gmail.
  • Use Google Vault for backup, archiving, and compliance.
  • Often review files shared externally (via ā€œShared with meā€ in Drive).

4. Strengthen Email and Communication Security

  • Enable Advanced phishing & malware protection in Gmail.
  • Set up DMARC, DKIM, and SPF records for your domain.
  • Regularly train users to be aware of phishing attempts.

5. Backup and Business Continuity

  • Implement 3-2-1 Backup rule:
    • 3 copies of data
    • 2 different storage types
    • 1 offsite or third-party backup (e.g., SpinBackup, Acronis).
  • Monthly restore tests.
  • Keep important files in an offline, encrypted vault.

6. Build a Security Culture

  • Provide Google Workspace Training about usage and security for all employees.
  • Regularly share cybersecurity insights and best practices.
  • Encourage quick and easy reporting of suspicious activity.
