In today’s digital-first business world, sensitive emails, files, passwords, and calendars are constantly at risk — from hackers, accidental leaks, or even overreaching cloud providers. Traditional business tools leave critical data exposed, disrupt workflows, and make compliance complicated.
That’s where Proton for Business changes the game.
Proton for Business is a complete, end-to-end encrypted ecosystem that secures emails, calendars, cloud storage, passwords, and network traffic. With zero-access encryption and Swiss privacy law protection, your team’s data remains fully under your control — not even Proton can access it.
Why Traditional Business Tools Fall Short
Modern organizations need:
- End-to-end encrypted communication across email, files, and credentials
- Multi-device access with centralized control
- Privacy and regulatory compliance (GDPR, HIPAA, CCPA)
- Easy migration from existing tools
- Seamless collaboration without data exposure
Traditional solutions often lead to:
- Emails and files exposed to cloud providers
- Shared credentials and weak password practices
- Fragmented apps for mail, storage, and calendars
- Complex compliance management and audit challenges
Proton solves these problems by providing a unified, secure business ecosystem where data privacy and workflow efficiency coexist.
