Proton Mail for Business serves organizations where data privacy, regulatory compliance, and end-to-end encryption are primary requirements. The platform prevents provider access to data through technical architecture.

Feature-by-Feature Comparison

Email Functionality

Google Workspace Gmail provides advanced filtering, powerful search functionality, and AI-powered features including Smart Compose and Smart Reply. Storage scales from 30GB to 5TB per user depending on tier. The service maintains 99.9% uptime through Google's global infrastructure.

Proton Mail implements end-to-end encryption by default, with all messages encrypted before leaving the sender's device. The platform supports 20 email addresses per user and up to 15 custom domains per user. Password-protected emails enable secure communication with recipients using any email provider. The Proton Scribe writing assistant provides AI-powered email composition while maintaining privacy standards.

Analysis: Google provides superior search and AI features. Proton offers stronger security through architecture preventing provider access to email content. Winner: Tie - depends on whether you prioritize features or privacy.

Calendar and Scheduling

Google Calendar integrates deeply with Gmail and Meet, enabling automatic event creation from emails and direct meeting link generation. The platform supports resource booking, multiple calendar management, and granular sharing permissions. Third-party applications integrate through Google's calendar API.

Proton Calendar encrypts all event details including titles, descriptions, and participant information. The service supports calendar sharing with team members and integrates with Proton Mail for meeting scheduling. Availability sharing enables meeting coordination without exposing detailed calendar information.

Analysis: Google offers more advanced scheduling features and broader integration. Proton provides unique encrypted calendar functionality protecting meeting details from provider access. Winner: Google Workspace for features.

File Storage and Document Collaboration

Google Drive forms the foundation of collaboration capabilities. Real-time co-editing in Docs, Sheets, and Slides enables simultaneous multi-user document work. Version history tracks changes with restoration capability. The platform supports offline access with automatic synchronization. File format compatibility covers common business document types with conversion capability for Microsoft Office formats.

Proton Drive provides 1TB of encrypted storage per user with end-to-end encryption protecting all uploaded files. The platform supports unlimited file sharing sizes. Version history extends to 365 days. Recent additions include an online document editor for basic document creation and editing. File sharing generates encrypted links with optional password protection and expiration dates.

Analysis: Google provides comprehensive collaboration functionality essential for teams requiring simultaneous document editing. Proton prioritizes file security through end-to-end encryption, suitable for sensitive document storage. Winner: Google Workspace for collaboration.

Video Conferencing

Google Meet integrates directly with Calendar and Gmail, enabling single-click meeting access. The Business Standard plan supports meetings up to 150 participants with recording capabilities. Features include screen sharing, breakout rooms, noise cancellation, and live captions. Meeting recordings save automatically to Google Drive.

Proton Meet (launched late 2025) now offers native, encrypted video conferencing. The platform supports screen sharing, chat, and waiting rooms with zero-access encryption. While it lacks the advanced webinar features and massive participant caps (500+) of Google Meet, it closes the video gap for privacy-conscious teams, eliminating the need for third-party solutions like Zoom.

Analysis: Google still wins on scale and advanced features (recording, noise cancellation, large meetings), but Proton now offers a viable native alternative for standard meetings. Winner: Google Workspace for scale and features, Proton for encrypted privacy.

Mobile Experience

Google Workspace apps maintain feature parity with desktop versions, providing full editing capability on mobile devices. Offline functionality enables work continuation without internet connectivity.

Proton apps provide secure email access with end-to-end encryption maintained on mobile devices. Push notifications alert users to new messages while maintaining privacy. Proton Bridge enables mobile email client integration while preserving encryption.

Analysis: Both platforms provide functional mobile experiences. Google's mobile apps offer more extensive collaboration features. Proton's mobile apps maintain security architecture consistency. Winner: Google Workspace - slight edge for features.

Privacy & Security Architecture

Encryption and Data Protection

The fundamental difference between these platforms lies in their encryption architecture.

Google Workspace encrypts data in transit using TLS and at rest using AES-256 encryption. However, Google maintains the capability to access user data, which the company utilizes for service improvements, spam filtering, and feature development. This access model, while standard for many cloud providers, means Google can technically read email contents and file data. The platform implements security controls including two-factor authentication, administrative security settings, and audit logging. Advanced plans include data loss prevention, security center monitoring, and endpoint management.

Proton Mail implements end-to-end encryption preventing the company from accessing user data. Messages encrypt on the sender's device and decrypt only on the recipient's device. This zero-access architecture means Proton cannot access data even under legal compulsion. Open-source code enables independent security audits, with the platform undergoing regular third-party security assessments. Proton Sentinel provides advanced account protection through AI-powered threat detection combined with human security specialists.

Key Difference: Data Access Capability

The critical distinction is not whether data is encrypted, but who can decrypt it:

  • Google Workspace: Google encrypts your data AND holds the keys to decrypt it
  • Proton Mail: Only you hold the keys; Proton cannot access your data even if compelled by law

This architectural difference determines privacy protection in scenarios involving government requests, data breaches, or internal access policies.

Data Jurisdiction and Legal Framework

Google Workspace operates as a United States company, subjecting it to U.S. law including the CLOUD Act, which enables law enforcement access to data stored globally by U.S. companies. Google publishes transparency reports detailing government data requests, which number in the thousands annually. The company's data centers span multiple countries, though data location may not determine legal jurisdiction. Google complies with various international regulations including GDPR, but fundamental jurisdiction remains in the United States.

Proton Mail operates under Swiss jurisdiction, providing strong legal privacy protections. Swiss law requires high legal thresholds for data access, typically requiring Swiss court orders. The country's privacy framework provides stronger protections than most jurisdictions. The company cannot access encrypted data even when legally compelled, limiting the scope of possible legal data access to metadata. Proton's transparency report details legal requests and the company's response framework.

Business Model and Incentive Alignment

Google Workspace generates revenue from Workspace subscriptions and from its broader advertising ecosystem. While Google states it does not use Gmail content for advertising in Workspace accounts, data contributes to improving Google's services across its product portfolio. This creates a business model where data utilization provides value to Google beyond subscription fees.

Proton Mail operates solely on subscription revenue without advertising or data monetization. The company's business model aligns with user privacy since data collection would contradict its core value proposition. This structure provides incentive alignment between user privacy interests and company business interests.

Privacy Consideration

Organizations should consider not just current privacy policies, but the underlying business incentives. A company whose revenue depends on data collection has different structural incentives than one whose revenue depends solely on subscriptions.

Pricing & Total Cost Analysis

Pricing appears straightforward, but total cost of ownership tells a different story when accounting for security tools.

Who Should Choose Which

The appropriate platform choice depends on honest assessment of organizational priorities.

Choose Google Workspace When:

Collaboration requirements dominate other considerations

You should select Google Workspace if your team requires real-time document co-editing, extensive third-party integrations, and familiar interfaces. The platform suits organizations where:

• Simultaneous multi-user document editing is essential for workflow
• Integrated video conferencing with Google Meet provides value
• Team members already use Gmail and Google tools
• Extensive third-party application integration is important
• Advanced AI features for email and productivity matter

• You primarily serve U.S. markets without stringent privacy requirements
• Lower entry cost is a priority and you'll add security tools separately

Choose Proton Mail When:

Privacy and security requirements are primary

You should select Proton Mail if data privacy, regulatory compliance, and end-to-end encryption are primary requirements. The platform suits organizations where:

• End-to-end encryption is required or strongly preferred
• You handle sensitive client, patient, or financial information
• You operate in regulated industries (healthcare, legal, financial services)
• You serve privacy-conscious markets or jurisdictions
• Swiss jurisdiction and data sovereignty provide meaningful advantages
• You need demonstrable privacy protections for compliance or brand
• GDPR or HIPAA compliance is a core operational requirement
• Privacy is part of your brand identity and customer promise
• The included VPN and password manager provide additional value
• You can integrate third-party tools for collaboration and video conferencing

Decision Framework

Ask yourself these questions:

  1. What matters more: Real-time collaboration features OR provider-blind encryption?
  2. Can Google access your data? Does your industry, customer base, or risk model permit this?
  3. What's your total security stack cost? Including VPN, password manager, and collaboration tools?
  4. Where are you on privacy regulations? Are you subject to GDPR, HIPAA, or similar frameworks?
  5. What's your team's technical comfort? Can they adapt to encrypted email workflows?

If collaboration and integration dominate your answers, choose Google Workspace. If privacy and data sovereignty dominate, choose Proton Mail.

Migration Considerations

Migration concerns often prevent platform changes despite clear benefits. Both platforms provide tools to simplify transitions.
