Proton Workspace Debuts as Secure Alternative to Microsoft 365 and Google Workspace

As Microsoft faces increasing scrutiny from the UK’s Competition and Markets Authority (CMA) over its dominance in business software, Proton is stepping in with a privacy-first alternative aimed at organizations looking to move away from Big Tech ecosystems.

Proton has officially launched Proton Workspace, a bundled office suite that combines its existing services into a single subscription. The offering directly targets businesses that rely on Microsoft 365 or Google Workspace, but want stronger privacy guarantees and more control over their data.

Proton Workspace combines email, storage, docs, and more

Proton Workspace brings together a full range of productivity tools under one platform, positioning itself as a complete replacement for traditional office ecosystems.

The Workspace Standard plan includes Proton Mail, Calendar with scheduling tools, Drive for storage, Docs and Sheets for collaboration, Meet for video calls, VPN for secure browsing, and Pass as a password manager.

For businesses with more advanced needs, Workspace Premium adds increased storage, email retention policies, higher participant limits for meetings, and access to Proton’s Lumo AI assistant.

Proton also confirmed that existing Business Suite customers will automatically receive the Standard plan at no additional cost, making the transition seamless for current users.

Privacy and independence are at the core

Proton is heavily emphasizing privacy as its main differentiator. All services in Proton Workspace use end-to-end encryption by default, ensuring that only users can access their data.

The company also highlights its open-source components and strict policy of not using user data for AI training. This stands in contrast to concerns around how larger tech companies handle enterprise data, especially as AI becomes more deeply integrated into productivity tools.

Operating under the Switzerland-based Proton Foundation, the company positions itself outside US jurisdiction, which it claims offers stronger data protection and compliance guarantees for businesses worldwide.

Pricing aims to stay competitive

Proton Workspace is priced to compete directly with established platforms.

Workspace Standard starts at $12.99 per month with annual billing or $14.99 monthly, while Workspace Premium costs $19.99 per month annually or $24.99 monthly.

Proton says the bundled approach delivers better overall value by combining multiple services into a single subscription, reducing the need for third-party tools.

Growing demand for alternatives to Big Tech

The launch comes at a time when the enterprise software market is seeing increased fragmentation and competition. Regulatory pressure on companies like Microsoft, along with ongoing debates around cloud licensing and AI integration, is pushing businesses to explore alternatives.

Tensions in the European market have also intensified following the recent Euro-Office initiative, which sparked a public dispute between ONLYOFFICE and Nextcloud over licensing and open-source compliance.

Proton appears to be capitalizing on this shift, offering a unified, privacy-first platform designed to appeal to organizations concerned about vendor lock-in, data sovereignty, and long-term compliance.

While competition heats up, Microsoft is still pushing forward with improvements to its own ecosystem. The company is reportedly working on faster file search capabilities in its Office apps, alongside deeper AI integration across Microsoft 365.

With regulators watching closely and new challengers entering the space, the battle for business productivity platforms is clearly entering a new phase.
