What is Proton Workspace?

Proton Workspace is a privacy-first office suite that bundles encrypted email, calendar, cloud storage, document editing, spreadsheets, video conferencing, VPN, password manager, and private AI into a single subscription for teams. It sits squarely in the secure productivity and collaboration category, designed to replace traditional office suites and cloud-content-collaboration platforms for organizations that cannot afford to compromise on data protection. Proton, the company behind Proton Workspace, reports over 100 million accounts and more than 100,000 business customers worldwide, including UN agencies and large enterprises, which signals real scale and maturity in production environments.

Originally launched as Proton Business Suite, the product evolved as Proton added Drive, Docs, Sheets, Meet, Pass, and AI capabilities on top of its core encrypted email and VPN offerings. In March 2026 it was rebranded as Proton Workspace to reflect that it had grown from a secure email solution into a full business productivity suite governed by Swiss privacy law. Today, Proton Workspace is the umbrella for Proton’s integrated business tools, all coexisting in one encrypted ecosystem rather than separate point solutions.
