Introducing Proton Workspace: An encrypted suite for team collaboration
Proton launches Proton Workspace, a privacy-first business suite that brings Mail, Calendar, Drive, Docs, Sheets, Meet, VPN, Pass and Lumo AI into one integrated offering. It adds new Standard and Premium plans and upgrades existing Business Suite customers.
When Proton was created in Switzerland in 2014, our mission was clear: restore digital agency to people who had lost control of their data to Big Tech. Over the past decade, more than 100 million people worldwide have trusted Proton to reclaim their privacy.
But we soon saw that this challenge extended far beyond individuals. In the same 10 years, over 100,000 businesses — from agile start ups to global enterprises — adopted Proton’s secure services. Today our encrypted email, password manager, VPN, cloud storage, and AI assistant (new window) AI assistant (new window) are used by organizations ranging from small teams and startups to United Nations agencies and Fortune 500 companies.
Recently, demand for Proton’s business solutions has surged, and companies have shifted from using individual services to adopting our entire, ever-growing ecosystem. That’s why, today, we’re launching Proton Workspace: a fully integrated suite that brings all of Proton’s privacy-first services into a single offering.
With Proton Workspace, businesses can finally break free from Big Tech dependency and take back complete control of their data.
What’s new in Proton Workspace
Proton Workspace combines Proton’s longstanding products with our new security-first services, including Proton Meet, Sheets, Docs and Lumo AI, across two new plans:
Workspace Standard
Everything you need for a secure collaborative workspace: Proton Mail, Calendar (now with appointment scheduling), Drive, Docs and Sheets, Meet, VPN, and Pass.
Annual price: $12.99 / €12.99 | Monthly price: $14.99 / €14.99
Workspace Premium
Includes all Workspace Standard features plus expanded storage, email data retention policies, higher participant limits per Meet call, and Lumo, our privacy‑first AI assistant.
Annual price: $19.99 / €19.99 | Monthly price: $24.99 / €24.99
Existing Proton Business Suite customers benefit from a free upgrade to Workspace Standard, including the addition of Proton Meet, at no additional cost.
Why Proton Workspace
With Proton Workspace, businesses finally have a trustworthy alternative to Big Tech that keeps sensitive business data secure.
Private (and encrypted) by default
Unlike Microsoft 365 and Google Workspace, which were created by companies that harvest user data as their business model, Proton has always-on end-to-end encryption and zero‑access encryption zero‑access encryption, meaning even we do not have access to your data.
Safer by design
Proton’s encryption makes our ecosystem safer by design. Because we do not have access to your encrypted data, an attacker that compromises Proton cannot access it either. Proton Workspace also includes advanced security tools to protect your organization from compromise, such as Proton Sentinel, which is successfully protecting some of the most highly targeted users in the world.
Open source and audited
Because our code is open source, anyone can independently verify that our encryption works as advertised and that there are no backdoors. All Proton apps are regularly independently audited and security tested.
Sovereign and shielded from US surveillance
Based in Europe, Proton ensures your data is protected by some of the world’s strongest privacy laws. Because Proton isn’t a US‑based company, we can’t be compelled by laws such as the US CLOUD Act (new window) US CLOUD Act (new window) to hand over your data to the US government or terminate your services. It is impossible for Proton to independently decrypt your data and share it with any third parties, including governments. Proton also operates our own infrastructure which is independent from Big Tech.
Protected from AI training
Proton’s encryption ensures we do not and cannot use your data for AI training, eliminating any chance that your private data gets publicly leaked through an AI output. Proton’s Lumo AI (new window) Lumo AI (new window) also uses zero-access encryption, meaning we do not have access to your saved chats, ensuring they’re never leaked or repurposed for AI model training. With Proton, there is no risk that your confidential business data becomes business intelligence for Big Tech, which is used later to compete with you.
Built with compliance in mind
Our advanced encryption shields your business from accidental leaks, data breaches, and state surveillance, while also helping you meet strict regulations. Proton Workspace simplifies compliance with regulations such as HIPAA, GDPR, and CCPA. It is also ISO 27001 and SOC2 certified, providing an additional layer of assurance for security conscious teams and clients.
Security beyond collaboration
Unlike other productivity suites, both Workspace Standard and Workspace Premium include Proton Pass and Proton VPN — two essential cybersecurity tools for your business. These tools feature breach detection alerts to notify you if a third-party tools you use suffers a data breach, and Dark Web Monitoring which automatically warns you if your data is being sold on the dark web.
Better value for money
Even though Proton Workspace includes additional valuable cybersecurity tools, it is less expensive than comparable Big Tech bundles and far cheaper than purchasing each service individually. Proton puts people ahead of profits, meaning we don’t do annual price increases. For over a decade, we have never raised prices on existing customers.
Make the switch to a privacy-first workspace
The need for privacy and security-centric business solutions is becoming increasingly urgent as geopolitical tensions rise and businesses face increasing resilience, surveillance, and cybersecurity risks.
Whether it’s your customers’ credit cards, your proprietary knowledge, or the trust of your partners, your most valuable assets are information. That’s why data breaches (new window) data breaches (new window) and ransomware attacks are at record highs, impacting both small and large organizations, and costing over $4 million per incident on average.
When you choose Workspace Standard or Workspace Premium, you’re not just protecting your business and saving money, you’re also supporting better independent technology that’s creating a more ethical and responsible digital ecosystem.
Proton has long stood for privacy, freedom, and democracy, principles which are safeguarded by our primary shareholder, the nonprofit Proton Foundation based in Switzerland. Our mission will continue to be providing the trusted, neutral foundation necessary to protect data in an unsecure world.
Switching to Proton Workspace is simple and seamless. Get in touch with our business team to get started today.
