Google Workspace vs Proton Workspace: Which Is Right for Your Business?

Google Workspace costs $7 to $22 per person per month. Proton Workspace costs $12.99 to $19.99. The price gap narrows — and in some configurations reverses — once you account for VPN, password management, and other security tools that Google doesn't bundle.

This guide covers pricing for a 10-seat team, feature differences, encryption boundaries, administration and compliance trade-offs, and a migration timeline to help you decide whether switching makes sense for your business.

What Are the Core Differences Between Google and Proton?

Google Workspace excels in real-time collaboration and integrations, whereas Proton Workspace prioritizes zero-access encryption and data privacy.

Before evaluating specific features, businesses must ensure they are comparing equivalent tiers. Google Workspace Business Starter ($7/user/month) is often mistakenly compared to Proton Workspace Standard ($12.99/user/month). This is an unequal baseline — Google's Starter plan limits storage to 30 GB pooled per user, restricts Gemini AI to Gmail only, and includes no business VPN or managed team password manager.

A tier-matched comparison puts Google Business Standard ($14/user/month) against Proton Workspace Standard ($12.99/user/month) — both on annual billing:

What Does Google Workspace or Proton Workspace Cost for a 10-Person Team?

A 10-seat Proton Workspace Standard setup costs $1,560 annually versus $1,680 for Google Business Standard. The gap widens if your organization separately purchases a VPN and password manager for Google users.

Base subscription cost

Proton Workspace Standard is $120/year cheaper than Google Business Standard on base subscription alone.

Optional security-tool scenario

Some organizations add a per-user commercial VPN and a managed password manager to Google Workspace. Under that configuration:

Under this example configuration, which adds a $9.99 VPN and $5 password manager to Google Workspace, Proton Standard costs approximately $1,920 less per year for 10 users. A managed password manager is a broadly defensible business control; a per-user commercial VPN is more dependent on your organization's network design and risk model — a consumer VPN does not replace zero-trust access, site-to-site VPN, endpoint management, DNS filtering, or EDR.

Potential replacement costs

Proton may introduce costs that the subscription price doesn't capture:

• Team chat: Proton has no equivalent to Google Chat — most teams add Slack or Microsoft Teams.
• MDM: Proton has no built-in endpoint management — organizations need Jamf, Intune, or similar.
• Presentations: No Slides equivalent — teams maintain PowerPoint, Canva, or a separate Google account.
• eDiscovery: Organizations with litigation-hold requirements may need specialized archiving tools.
• Migration labor: Plan for admin time, user training, and document-format remediation (see migration section below).

Teams auditing their annual software budgets can review Proton's bundled standard and premium tiers to see how this consolidation offsets existing SaaS costs.

Productivity, Collaboration, and Application Differences

Google Workspace offers superior real-time collaboration, a dedicated presentation app, seamless offline editing, and broader AI capabilities.

There are specific workflows where Google's mature ecosystem cannot be replaced. Google Slides has no direct equivalent in Proton Workspace — there is no beta version and no confirmed roadmap entry. If your team delivers client pitches, board decks, or investor presentations, migrating to Proton requires maintaining a secondary tool like PowerPoint, Canva, or a standalone Google account.

Google's offline editing in Chrome works across Gmail, Docs, Sheets, and Slides. Proton's offline capabilities for Docs and Sheets are more limited, especially outside the browser. Teams with staff who regularly work from planes or areas with unreliable connectivity will feel this gap.

Google Meet is woven into Gmail, Calendar, and Google Chat — one-click joins from any surface. Proton Meet is a full end-to-end encrypted conferencing tool (launched March 2026 using the MLS protocol), but its integration with Proton Calendar isn't yet as seamless as what Google provides.

Gemini AI operates inside Gmail, Docs, Sheets, Slides, Meet, Drive, and Chat on the Business Standard tier. Proton's Lumo was rebuilt as Lumo 2.0 in June 2026, adding Fast and Thinking reasoning modes, image generation, and encrypted memory/Projects. Lumo is included with Workspace Premium and available separately as Lumo Plus ($12.99/month) or Lumo Professional ($14.99/user/month for teams). A free Lumo tier exists for any Proton user, but it is not a Workspace Standard entitlement in the same sense as Mail, Drive, VPN, or Pass. Lumo's scope is also narrower than Gemini — primarily AI chat and the Proton Scribe email writing assistant — rather than being embedded across every productivity app.

Google Groups combined with Gmail's collaborative inbox handles support@, billing@, and info@ addresses where multiple people need to read and reply from a single address. Proton offers Email Groups for distribution, but these function as distribution lists rather than collaborative inboxes. There is no direct equivalent to Google Groups' shared reply workflow — teams typically work around this with a dedicated shared account, but the gap remains a functional limitation for organizations that rely heavily on shared mailboxes.

If your business runs on Google Ads, Google Analytics, Google Search Console, and Google Tag Manager, the single-identity integration saves real time. Proton has no equivalent — you'd still sign into all those Google services separately.

On mobile, Google Workspace integrates Meet, Chat, and Calendar directly into the Gmail app — a single download covers most daily workflows. Proton requires separate app downloads for Mail, Calendar, Drive, Pass, and VPN on iOS and Android. For employees accustomed to a unified mobile experience, managing five individual Proton apps is a common friction point that IT admins should address during onboarding.

Security, Privacy, and AI Data Handling

Proton Workspace prioritizes data privacy through zero-access encryption, Swiss legal process, and bundled cybersecurity tools. Google provides contractual data-handling commitments with mature administrative controls.

Zero-access encryption vs. provider-managed encryption

Proton's architectural foundation is zero-access encryption. Google encrypts data in transit and at rest, but Google holds the encryption keys and retains the ability to access your data. Google can and does comply with valid legal requests for content when required. Proton uses end-to-end and zero-access encryption for supported content. Private keys are generated client-side and stored on Proton's servers only in encrypted form, so Proton cannot decrypt protected content. This distinction matters for legal privilege, patient data, financial records, and any information where "encrypted" needs to mean "inaccessible to the provider."

For a deeper look at what's included and how each tool performs, see our full Proton Workspace review.

Jurisdiction and legal process

Proton is headquartered in Switzerland and is generally subject to Swiss legal process. Foreign data requests must typically pass through Swiss international-assistance procedures rather than direct compliance with US law like the CLOUD Act. Proton can disclose information available to it under valid Swiss orders, although it states that encrypted emails, files, and invitations cannot be decrypted by Proton. For businesses with EU clients under GDPR scrutiny, this can provide a clearer data-location and legal-jurisdiction explanation during vendor reviews. Proton is SOC 2 Type II certified (July 2025) and ISO 27001 certified (May 2024).

Bundled security tools

Proton Workspace Standard includes Proton Pass for Business (password manager with team vaults, breach detection, and Dark Web Monitoring) and Proton VPN (encrypted connections with ad-blocker and malware protection). Buying equivalent tools separately alongside Google Workspace costs $10–$15/user/month on top of your Google subscription.

For organizations evaluating these bundled security and compliance capabilities, Proton offers a 14-day free trial on all Workspace plans.

Proton's apps are open source. The encryption claims are verifiable by anyone who reads the code. The SOC 2 Type II audit (conducted by Schellman) and ISO 27001 certification add third-party validation on top of code transparency.

Gemini vs. Lumo: how each platform handles your AI data

Both platforms include AI assistants, but their data handling architectures are fundamentally different.

Google Gemini is governed by the Cloud Data Processing Addendum (CDPA). Google's enterprise terms explicitly state that workspace customer data — including prompts, generated responses, and uploaded files — is not used to train or fine-tune foundational AI models without permission. Gemini processes your queries on Google's servers in plaintext. Google has technical access to the content of your prompts while generating responses.

Proton Lumo takes a structurally different approach. Prompts are encrypted client-side using AES-256-GCM with a fresh per-request key, then wrapped with Proton's PGP public key. Only dedicated Lumo GPU servers can decrypt the content — Proton's general infrastructure never sees your queries in plaintext. However, the LLM server does decrypt the request to perform inference, meaning plaintext exists briefly during processing on Proton-controlled hardware. The Lumo 2.0 upgrade (June 2026) rebuilt the underlying model architecture — adding Fast and Thinking modes, image generation, and encrypted memory — without changing this encryption model. No data is sent to third-party AI providers, and stored chat history and memory use zero-access encryption that only you can read.

The practical distinction: Google makes a contractual commitment not to train on your data but retains technical access during processing. Proton adds encrypted user-to-Lumo processing with zero-access encrypted history, limiting its own access outside the moment of inference. For businesses where AI-assisted drafting involves privileged or regulated content, this architectural difference may determine which platform your compliance team will approve. Lumo is included with Workspace Premium, or available as its own subscription independent of Workspace — Lumo Plus and Lumo Professional pricing covers the standalone option.

Encryption boundaries in practice

Proton provides end-to-end encryption within its own apps, but this protection does not extend to data shared outside the Proton ecosystem. The privacy advantage is meaningful but conditional — it depends on how your team actually works.

Durable privacy:

• Email between two Proton addresses is end-to-end encrypted on both ends. Neither Proton nor any intermediary can read the content.
• Files in Proton Drive accessed only through Proton apps remain zero-access encrypted.
• Calendar events in Proton Calendar are encrypted. Meeting details, attendee lists, and notes stay private.
• Proton Meet calls use the MLS protocol for end-to-end encryption of audio, video, and in-call chat.

Meaningful but limited:

• Email from Proton to Gmail is encrypted in transit (TLS) but readable by Google on the recipient's end. The metadata — who you emailed, when, and how often — is visible to both providers.
• Password-protected emails sent to non-Proton addresses add a layer of encryption the recipient must unlock, but this adds friction and is impractical for routine correspondence.

When data leaves Proton's encrypted environment:

• If your team copies Proton Drive files to a third-party service — Dropbox, Slack file shares, or a cloud backup tool — those copies exist outside Proton's encryption. The original Proton copy remains encrypted, but the exported copy does not.
• Browser extensions that scrape inbox content can access decrypted data in memory.
• Auto-forwarding Proton Mail to a Gmail address for convenience means the forwarded copy is readable by Google.

Administration, Retention, eDiscovery, and Compliance

Google Vault offers built-in legal holds and eDiscovery. Proton Workspace Premium adds organization-wide retention rules, but lacks a Vault-equivalent eDiscovery platform.

This is a critical consideration for regulated industries that IT directors should evaluate before switching.

eDiscovery and legal holds

Google Workspace Business Plus ($22/user/month) and Enterprise tiers include Google Vault, which provides full eDiscovery capabilities: legal holds that preserve data indefinitely (even if users delete it), full-text content search across Gmail, Drive, and Chat, matter management, and export tools for litigation review. An admin can place a hold on an employee's inbox and search its contents without the employee's involvement.

Proton does not currently provide Vault-style centralized cross-account search, matter management, or formal legal holds. Its zero-access encryption model also makes provider-side full-text discovery more difficult to implement.

Retention policies (Workspace Premium)

Proton Workspace Premium now provides organization-wide retention rules. Admins can retain mail indefinitely, preserve messages that users delete, and access retained mail for non-private organization members. This is a meaningful improvement over the previous state — Proton can no longer be described as having no ability to retain content independently of users. However, the real limitation remains: there is no centralized Vault-style cross-account search, export, or formal legal-hold workflow.

Under Swiss law, Proton can provide account information and metadata available to it in response to valid orders but not encrypted message content. Organizations using Proton for compliance purposes should design retention workflows around Premium's admin retention rules and coordinate encrypted exports where needed.

Business administration and offboarding

Google Workspace provides mature admin capabilities: user provisioning and deprovisioning, admin access to departing employee data, account recovery, detailed audit and sign-in logs, directory synchronization, and SCIM-based automated provisioning on Enterprise tiers. SSO integration is available across all tiers via SAML.

Proton Workspace's admin console handles user management, custom domain administration, and organization-level settings. Proton distinguishes between organization-managed and private users — admins have different levels of access depending on membership type. For offboarding, admins can access non-private member data through retention policies on Premium, but the process is less automated than Google's admin transfer tools. Proton now supports SSO and SCIM in parts of its business product stack, including documented automated user provisioning via Okta and Microsoft Entra. Availability and administrative scope vary by plan and product, so organizations should confirm entitlement for the specific Workspace configuration they are considering.

For IT directors evaluating either platform, user lifecycle management — from provisioning through offboarding and data ownership transfer — is often as important as encryption architecture.

Compliance capability matrix

Migration and Compatibility

Migrating a 10-user team to Proton Workspace requires four to eight hours of admin work, with Drive file transfers needing the most manual effort.

Email, contacts, and calendar migration: Proton now offers an organization-level Easy Switch process that imports Google Workspace email, contacts, and calendar events. A Workspace super administrator authenticates the connection, and Proton handles the migration across all user accounts. This replaces the earlier per-user IMAP and ICS import workflow. For a 10-seat team with moderate email volume, expect 2–4 hours for the import to process, plus time to verify that everything landed correctly. Recurring events should be spot-checked after import.

Drive files: This is the most labor-intensive step. Drive files and native Google document formats (Docs, Sheets, Slides) are not covered by Easy Switch and still require a separate migration workflow. Download files from Google Takeout, then upload to Proton Drive. Google Docs and Sheets export as .docx and .xlsx files that Proton Docs and Sheets can open, although complex formatting and formulas may require correction. Google Slides exports as .pptx, but Proton has no presentation editor — those files require PowerPoint, LibreOffice, Canva, or another compatible application. Once migrated, Proton Drive's desktop apps for Windows (File Explorer integration with background sync) and macOS (Finder integration with on-demand sync, offline file access) provide a familiar local folder experience. There is no Linux desktop GUI — Linux users are limited to CLI/SDK tools or the web interface.

File-format and spreadsheet compatibility

Proton Docs and Sheets can open exported Microsoft Office files, but teams should expect limitations with:

• Complex spreadsheet formulas — advanced functions, named ranges, and cross-sheet references may not fully translate.
• Pivot tables and charts — limited support compared to Google Sheets or Excel.
• Macros and Apps Script — no equivalent automation layer exists in Proton Sheets.
• Comments and suggested edits — may not carry over from Google Docs exports.
• Presentations — Google Slides files export as .pptx, but Proton has no presentation app to open them. Teams need PowerPoint, Canva, or a separate Google account.

For teams considering a switch, testing three representative files before committing — a formatted document, a working spreadsheet with formulas, and a presentation — will surface compatibility issues early.

External collaboration

Teams should also evaluate how Proton users collaborate with external contacts on Google or Microsoft:

• External users can view and edit Proton Docs without creating a Proton account. Proton Sheets also supports public links with viewer or editor permissions, although collaborators invited directly by email currently need a Proton account. The larger limitation is cross-platform file compatibility and workflow maturity, not the inability to collaborate externally.
• Sharing permissions are managed through link-based access with optional passwords and expiration dates.
• Comment threads and version history do not carry across platforms when files are shared via exported documents rather than native Proton links.
• Proton Meet invitations can be sent to non-Proton recipients, and guests can join without creating a Proton account.

For businesses where most collaboration happens with external clients on Google or Microsoft, the gap is less about access and more about the maturity of cross-platform workflows compared to Google's deeply integrated sharing model.

Team chat: Proton has no equivalent to Google Chat or Slack. You'll need a separate messaging tool. Most teams migrating to Proton use Slack, Microsoft Teams, or Signal for team messaging alongside the Proton suite.

Domain verification and MX records: Updating your domain's MX records to point to Proton's mail servers is a 1–2 hour job for a technically capable admin. Proton provides step-by-step guides for all major domain registrars.

Mobile app setup: Each user needs to download and configure separate Proton apps for Mail, Calendar, Drive, Pass, and VPN. Budget an additional 15–20 minutes per user for mobile setup compared to Google's single-app onboarding.

Realistic total time for a 10-seat team: 4–8 hours of admin work, spread over 1–2 days. Individual users will need another 30–60 minutes each to set up their Proton apps and verify their email. The biggest friction point is retraining habits — muscle memory for Gmail keyboard shortcuts, Google Drive sharing patterns, and Meet links embedded in recurring calendar events.

Which Businesses Should Choose Each Platform?

Privacy-focused healthcare and legal organizations may favor Proton when confidentiality outweighs Vault-style discovery and broader workflow integration. Teams embedded in Google's ecosystem should stay with Google for collaboration and administrative depth.

The decision hinges on your industry requirements and daily workflow patterns. Here are the specific scenarios where the answer is clearest.

Switch to Proton If

You're a privacy-focused healthcare practice. Proton offers a HIPAA BAA on request — email legal@proton.me with the subject "HIPAA BAA." Proton states that it cannot decrypt end-to-end encrypted content for disclosure, although it may disclose account information and metadata available to it under valid Swiss orders. Google also offers a HIPAA BAA (accepted through the Admin console), but Google retains the technical ability to access your data. Neither platform makes an organization HIPAA compliant by itself — compliance depends on your policies, training, and controls — but for organizations that prioritize provider-inaccessible storage of clinical data, the architectural difference is meaningful. Note that encryption alone does not establish HIPAA compliance.

You're a law firm handling privileged communications. Attorney-client privilege combined with Swiss legal process can be a strong combination. Foreign data requests generally must follow Swiss international-assistance procedures. Note the eDiscovery and retention trade-offs above — build your retention workflow before migrating, and evaluate whether the lack of Vault-style discovery is acceptable for your practice.

You have EU clients who've asked about GDPR data residency. Proton's Swiss infrastructure can provide a clearer data-location and legal-jurisdiction explanation during vendor reviews. This may simplify GDPR compliance discussions, though it does not guarantee compliance on its own.

You're already paying separately for a VPN and password manager. If your current Google Workspace cost includes $10–$15/user/month in standalone security tools, switching to Proton Workspace Standard will likely cost less for more integrated coverage.

Stay with Google If

Your business runs on Google Ads, Analytics, and Search Console. The single-sign-on continuity across Google's advertising and analytics products has no equivalent on Proton. You'd still need a Google account for those tools, which defeats the consolidation benefit.

You deliver client-facing presentations regularly. No Slides equivalent means maintaining a second tool for presentations. If your team builds and delivers slide decks weekly, this gap is a daily friction point.

You rely on shared inboxes. If three or more people manage support@, billing@, or info@ using Google Groups + collaborative inbox, Proton's Email Groups (distribution lists) do not provide the same shared-reply workflow. Teams typically work around this with dedicated shared accounts, but the gap adds complexity.

You need eDiscovery or legal holds. If your compliance team requires admin-searchable archives and automated litigation holds, Google Vault (Business Plus or Enterprise) or Microsoft Purview provides capabilities that Proton's architecture cannot replicate.

You need built-in device management. Google Workspace includes endpoint management on all plans — basic MDM (password enforcement, remote account wipe, screen lock requirements) is enabled by default, with advanced controls (full device wipe, app distribution, Android work profiles) on Business Plus and Enterprise. Proton Workspace has no integrated MDM. Organizations using Proton will need a separate solution like Jamf, Microsoft Intune, or Workspace ONE to enforce device policies and remotely wipe a lost phone or tablet.

Your team works offline frequently. Google's offline mode is mature across all apps and devices. Proton's offline capabilities are more limited. Field teams, frequent travelers, or anyone regularly working without connectivity will feel the difference.

Consider a Hybrid Approach

Some teams run Google Workspace for collaboration and Proton Mail as the official email address for sensitive client communications. This isn't elegant — it requires discipline to route the right conversations through the right system — but it's a real pattern we see with law firms and financial advisors who want Proton's encryption for client-facing email without giving up Google's productivity tools.

If the privacy benefits outweigh the workflow adjustments for your industry, explore a Proton Workspace trial to test the full feature set before committing.
