Bottom Line
Proton Business Suite offers a genuine alternative to mainstream productivity platforms for organizations that value privacy over convenience, providing enterprise-grade security features at accessible pricing while maintaining ease of use. The platform succeeds in delivering genuine privacy protection without sacrificing essential business productivity, representing a meaningful choice for businesses seeking to balance productivity with privacy, particularly as data protection regulations become more stringent and privacy awareness increases among customers and partners.
What Is Proton Business Suite?
Proton Business Suite is a comprehensive encrypted productivity platform that protects all business data within a single ecosystem, including mail, calendar, cloud storage, password manager, and VPN services. Unlike traditional business platforms that monetize user data or provide limited encryption, Proton's approach ensures that only your organization can access your business information—not even Proton itself can decrypt your data.
The platform addresses a fundamental challenge facing modern businesses: maintaining productivity while ensuring genuine privacy protection. Built by the Swiss company Proton AG, the suite emerged from growing awareness that businesses need alternatives to platforms where data privacy takes a secondary role to advertising revenue.
Core Platform Components
Proton Mail for Business
Secure email with 20 addresses per user and support for 15 custom email domains
Proton Calendar
Encrypted calendar with meeting scheduling and availability sharing
Proton Drive
1 TB of secure cloud storage per user with unlimited file sharing sizes
Proton VPN Business

Unified Ecosystem Approach
The unified ecosystem approach eliminates the complexity of managing multiple vendors while ensuring consistent privacy protection across all business functions. This integration provides significant advantages over traditional solutions that require piecing together services from different providers.

Security Analysis
Proton Business Suite implements comprehensive security measures that go beyond traditional productivity platforms, providing genuine privacy protection through zero-access encryption, advanced threat detection, and Swiss privacy law compliance.
