Microsoft 365 vs Google Workspace for Enterprise
The definitive enterprise productivity suite comparison for security, compliance, and collaboration
EPC Group — founded in 1997, headquartered in Houston, a Microsoft Solutions Partner holding all six solutions designations — publishes this guide.
Microsoft 365 typically wins for enterprises requiring deep desktop productivity, regulated-industry compliance (HIPAA, SOC 2, FedRAMP, CMMC), and integrated Microsoft platform pull (Teams, SharePoint, Power Platform, Defender, Sentinel, Purview). Google Workspace wins for browser-native, collaboration-first organizations with simpler compliance scopes and Chromebook fleets. EPC Group's Microsoft 365 consulting practice migrates and governs the regulated, desktop-heavy enterprises this comparison describes.
Microsoft 365 and Google Workspace are the two dominant enterprise productivity suites. Microsoft 365 leads in compliance (90+ certifications, HIPAA, FedRAMP, ITAR), security depth, and AI with Copilot. Google Workspace leads in browser-native collaboration and simplicity. This comparison covers pricing, security, AI, and which suite wins by use case.

When to Choose Each Platform
Choose Microsoft 365 When
- You operate in regulated industries requiring FedRAMP High, HIPAA BAA, HITRUST, CJIS, or ITAR compliance
- Advanced Excel is mission-critical -- financial modeling, Power Query ETL, or VBA automation
- Enterprise content management with metadata, retention, records management is required
- You need unified identity management through Entra ID with Conditional Access
- You already run Azure or Dynamics 365 -- native integration across the Microsoft stack lowers integration cost
- Power BI analytics and Power Platform low-code development are strategic initiatives
- Desktop Office applications are non-negotiable for your workforce
- Phone system consolidation through Teams Phone replaces existing PBX
- Advanced threat protection and insider risk management are security requirements
Choose Google Workspace When
- Your workforce is primarily browser-based and does not require desktop Office applications
- Real-time collaboration in Docs/Sheets is the primary productivity requirement
- You are a Google Cloud Platform (GCP) customer and want unified cloud billing
- Simplicity is valued over feature depth -- fewer admin controls means faster deployment
- Your organization is under 1,000 users with basic compliance needs (SOC 2, ISO 27001)
- Education or startup environments where cost-per-user is the primary decision factor
- Chromebook-heavy environments where Chrome OS integration is essential
- Basic email and file sharing meets your needs without advanced ECM or DLP

Frequently Asked Questions
Is Microsoft 365 or Google Workspace better for large enterprises?
Microsoft 365 is generally better for large enterprises (1,000+ users) due to its superior compliance capabilities (90+ certifications including FedRAMP High, HIPAA BAA, ITAR), advanced security through Microsoft Defender and Purview, and deeper integration with enterprise systems via Azure AD/Entra ID. Google Workspace Enterprise Plus has improved significantly but still lacks the depth of compliance certifications and advanced threat protection that regulated industries require.
How does Microsoft 365 Copilot compare to Google Workspace Gemini?
Microsoft 365 Copilot ($30/user/month) integrates across Word, Excel, PowerPoint, Outlook, and Teams with enterprise-grade data protection through Microsoft Graph. Google Workspace Gemini (included in Business and Enterprise plans) provides AI assistance in Gmail, Docs, Sheets, and Meet. Copilot excels at complex document generation, Excel data analysis, and PowerPoint creation. Gemini is strong at email drafting and meeting summaries. For enterprise data security, Copilot offers more granular controls through Purview sensitivity labels.
What is the pricing difference between Microsoft 365 E5 and Google Workspace Enterprise Plus?
Microsoft lists Microsoft 365 E5 at $60.00/user/month (annual commitment, with Teams; read 2026-10-21) and includes advanced security (Defender for Office 365 Plan 2), compliance (eDiscovery Premium, insider risk management), analytics (Power BI Pro), and phone system (Teams Phone). Google Workspace Enterprise Plus costs $25/user/month but requires add-ons for equivalent security ($6-12/user for BeyondCorp Enterprise, separate DLP tools, third-party SIEM). When factoring in equivalent feature parity, Google Workspace typically costs $40-50/user/month -- making the effective price difference smaller than list prices suggest.
Can we use both Microsoft 365 and Google Workspace together?
Yes, hybrid deployments are possible but introduce complexity. Common patterns include using Google Workspace for email/collaboration with Microsoft 365 for desktop apps and compliance, or using Microsoft 365 as the primary suite with Google Workspace for specific teams. However, dual licensing increases costs by 40-60%, creates identity management challenges, and fragments security policies. EPC Group typically recommends standardizing on one platform within 12 months of evaluation.
How does SharePoint compare to Google Drive for enterprise document management?
SharePoint offers enterprise content management with metadata taxonomies, retention policies, records management, custom workflows (Power Automate), and site-level governance. Google Drive provides simpler file storage with Google Docs collaboration but lacks built-in records management, granular retention policies, and custom metadata. For regulated industries requiring document lifecycle management, information barriers, or legal hold, SharePoint is significantly more capable. Google Drive wins on simplicity for basic file sharing.
What compliance certifications does each platform hold?
Microsoft 365 holds 90+ compliance certifications including FedRAMP High, DoD IL5, HIPAA BAA, HITRUST, SOC 1/2/3, ISO 27001/27017/27018, ITAR, CJIS, GxP, and PCI DSS. Google Workspace holds approximately 30 certifications including FedRAMP High (for Government), SOC 1/2/3, ISO 27001/27017/27018, and HIPAA BAA. Microsoft has a clear advantage in government (GCC High, DoD), healthcare (HITRUST), and financial services (regulatory compliance) verticals.
How long does it take to migrate from Google Workspace to Microsoft 365?
A typical Google Workspace to Microsoft 365 migration for 1,000 users takes 6-10 weeks including planning, pilot (50-100 users), phased migration, and post-migration optimization. Key challenges include converting Google Docs/Sheets formatting to Office formats, migrating Google Sites to SharePoint, reconfiguring SSO and conditional access, and retraining users on the Microsoft ecosystem. EPC Group has completed 100+ G Suite/Workspace to M365 migrations with 99.5% data fidelity.
Which platform has better mobile device management?
Microsoft 365 includes Microsoft Intune for enterprise mobility management (MDM + MAM) covering device enrollment, compliance policies, conditional access, app protection, and remote wipe -- all included in E3/E5. Google Workspace offers Endpoint Management with basic MDM capabilities but requires Chrome Enterprise Upgrade ($6/device/month) for advanced features. For organizations managing iOS, Android, Windows, and macOS devices, Intune provides significantly deeper cross-platform management.
Which suite do federal contractors handling CUI need for CMMC?
Federal contractors managing Controlled Unclassified Information (CUI) require Microsoft 365 GCC High. GCC High meets CMMC Level 2 (110 NIST 800-171 controls) and CMMC Level 3 (134 controls).
