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

IT Security Guideline

Protecting Your Business with Practical, Scalable Security

For many small and medium-sized businesses (SMBs), Google Workspace is the backbone of daily operations — powering email, collaboration, and cloud storage. But as your team grows, so does the risk of data breaches, phishing, and accidental data leaks.

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

Here’s a practical IT Security Guideline tailored for SMBs using Google Workspace.

  • Enable 2-Step Verification (MFA) for all accounts.
  • Use Admin Console → Security → Less Secure App Access = OFF.
  • Enforce strong password policies and consider Passkey sign-in for admins.
  • Assign roles properly – Admin rights only for IT or management.
  • Disable or suspend unused accounts immediately.

💡 Use Google Workspace Admin Reports to monitor suspicious logins or failed attempts.

  • Require all company devices to sign in with Google accounts under device management.
  • Enforce screen locks, encryption, and automatic OS updates.
  • Apply Basic Mobile Management (included in all Workspace editions) to remotely wipe lost devices.
  • Avoid public or shared computers for accessing Workspace.

💡 Business Standard and Business Plus plans offer advanced endpoint management — ideal for small teams.

  • Audit Drive sharing settings:
    • Default sharing = “Restricted
    • Disable “Anyone with the link” unless business-approved.

  • Enable Data Loss Prevention (DLP) in Drive and Gmail to prevent sensitive info leaks.
  • Use Google Vault for backup, archiving, and compliance.
  • Regularly review files shared externally (via “Drive → Shared with me”).

💡 Keep customer and financial data in shared drives with limited editor rights.

  • Enable Gmail’s advanced phishing & malware protection.
  • Set up DMARC, DKIM, and SPF records for your domain.
  • Disable automatic email forwarding rules from external senders.
  • Train users to recognize phishing attempts — even the smartest filters can’t block human curiosity.

💡 Use Google’s “Security Sandbox” to detect zero-day attachments.

  • Implement 3-2-1 Backup rule:
    • 3 copies of data
    • 2 different storage types
    • 1 offsite or third-party backup (e.g., SpinBackup, Acronis).

  • Schedule monthly restore tests.

Keep key admin credentials in an offline, encrypted vault.

  • Provide onboarding security awareness training for all employees.
  • Share short internal tips about phishing, password hygiene, and sharing rules.

Encourage quick reporting of suspicious activity — better safe than sorry.
