The definitive enterprise productivity suite comparison for security, compliance, and collaboration
After migrating 500+ organizations between productivity platforms and managing 100,000+ user deployments, EPC Group provides a data-driven comparison of Microsoft 365 and Google Workspace. While both platforms enable modern work, they serve fundamentally different enterprise needs -- especially around security, compliance, and advanced productivity capabilities.

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.
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.
Microsoft 365 E5 costs $57/user/month 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.
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.
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.
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.
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.
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.
