Microsoft 365 is the better default for a small business that relies on desktop Word, Excel, or PowerPoint, uses Teams, or needs integrated identity and device management. Proton Workspace is a stronger fit when end-to-end encryption and a privacy-focused bundle are the priorities. The right choice depends on the work your team actually needs to do—not on treating the two suites as interchangeable.

Choose Microsoft 365 if your work depends on Office and Teams
Microsoft 365 is the more straightforward fit if staff exchange complex Word documents, Excel workbooks, or PowerPoint presentations with customers and partners, or if the business already runs meetings and shared work around Teams. The plan tier matters: Basic provides web and mobile Office apps, while Standard and Premium add desktop apps. If installed Office software is essential, Basic is not the equivalent choice.

Compare collaboration by workflow, not app names
Proton lists Docs and Sheets alongside Drive and Meet; Microsoft’s business suite centers on Word, Excel, PowerPoint, Teams, OneDrive, and SharePoint. Both bundles cover familiar business tasks, but the available plan descriptions do not establish feature-for-feature parity. Before switching, test the actual documents, spreadsheets, meeting patterns, and external sharing your team uses.

Compare the prices carefully
Microsoft’s US pricing page for plans with Teams showed yearly-billed rates of $7 per user/month for Business Basic, $14 for Standard, and $22 for Premium when accessed in 2026. These are a dated US snapshot, not a universal quote: Microsoft also presents plan variants with and without Teams, and regional pricing, billing cadence, and taxes can change the checkout total. Confirm the intended market, exact SKU, and billing term. Microsoft’s business plan comparison
A dependable per-user Proton Workspace price was not established here, so comparing subscription totals requires checking Proton’s live plan selector for your country, monthly or annual billing, taxes, and any current offer. Proton Workspace plans
For either provider, evaluate the cost against existing subscriptions and commitments as well as the services you would actually use. The plan descriptions alone cannot establish migration effort or the total cost for a particular business.

- List non-negotiables. Note whether you require desktop Office apps, Teams, a particular security or device-management control, encrypted collaboration, or a specific meeting capacity.
- Map the requirements to a tier. For Microsoft, distinguish Basic’s web/mobile apps from Standard’s and Premium’s desktop apps; for Proton, compare Standard and Premium’s published storage, domain, and meeting limits.
- Check your real workflows. Identify documents, spreadsheets, email, calendars, shared files, identities, and integrations that would be affected by a change.
- Verify the actual offer and terms. Check current regional pricing, billing cadence, plan variant, taxes, feature availability, trial conditions, and any local compliance requirements directly with the provider.
Verdict
For a small business built around installed Office apps, Teams, and Microsoft’s integrated administration tools, Microsoft 365 is the stronger default. For a team that puts privacy-first encryption ahead of Office compatibility and wants a bundle that also includes VPN and password management, Proton Workspace deserves closer consideration. Decide against your required workflows and exact plan terms, rather than assuming either suite is a universal substitute for the other.
