Would you move your company's data to a provider outside the US to ensure data sovereignty?
Proton has extended its Easy Switch for Business tool to support migrations from Microsoft 365, joining existing compatibility with Google Workspace. The tool is designed to move emails, contacts, and calendars while avoiding common pitfalls like data loss or system downtime.
Why it matters
Many security leaders are concerned about the risks of relying on US-based providers, particularly regarding potential foreign government pressure or access limitations. This migration tool provides an alternative for organizations seeking to adopt Swiss-based, encrypted communication infrastructure.
The tool uses dual-send periods to keep legacy systems and Proton in sync during the transition. Administrators connect the Proton platform directly to their existing Microsoft 365 or Google Workspace tenant to authorize the migration.
The players
Proton
A Swiss-based technology company known for developing encrypted email and privacy-focused communication services.
Microsoft 365
A productivity software suite from Microsoft that serves as a dominant platform for corporate email and calendar management.
The details
Proton, which is headquartered in Switzerland, applies end-to-end and zero-access encryption by default to all user data. More than 100,000 organizations currently utilize Proton products to manage secure corporate communications.
Timeline
June 2026: Easy Switch for Business launched for Google Workspace users.
September 29, 2026: The tool was officially extended to support Microsoft 365 migration.
The Tech Race
This move highlights the intensifying competition to offer secure, decentralized alternatives to legacy US productivity suites. It represents a broader effort to provide businesses with the technical capability to switch providers without risking operational continuity.
Business administrators can now execute platform transitions with reduced risk of inbox breakage or data loss. The integration allows companies to maintain communication sync via dual-send periods, ensuring staff do not lose access to critical messages during the switch.
The takeaway
Organizations prioritizing data sovereignty should evaluate whether their current providers offer adequate portability for future transitions. Adopting platforms with built-in migration tools can significantly lower the technical and operational barriers to changing email vendors.
