Proton launches Workspace with Lumo

Work software is the category here. The stakes are simple — where your company’s email, files, meetings, and now AI prompts live. That has become a (proton.me)r data, they also feed AI features with it. Proton’s move on March 31 was to bundle its whole business stack into Proton Workspace, with Lumo as the privacy-first AI layer on top. (proton.me) ### What is Proton actually launching? Proton Workspace is basically Proton’s answer to Google Worksp(proton.me)oton Mail, Calendar, Drive, Docs, Sheets, Meet, VPN, and Pass, instead of making companies stitch those together one by one. Proton says existing Business Suite customers were upgraded to Workspace Standard at no extra cost, which makes this feel less like a brand-new product and more like a formal packaging of tools Proton had been building toward for a while. (proton.me)the hook because it turns Workspace from a secure office suite into a secure office suite with AI. Proton puts Lumo only in Workspace Premium, and the pitch is very specific: teams can use AI for drafting, summarizing, planning, and file-based work without handing over chats for model training or broad logging. That matters because AI is now the feature buyers expect, but it is also the feature that makes privacy promises easiest to break. (proton.me) ### What makes (proton.me)rchitecture and jurisdiction. Proton says Workspace uses end-to-end or zero-access encryption across its services, says it cannot read stored customer data, and leans hard on being based in Switzerland and hosted in Europe for stronger privacy protections. Lumo gets the same treatment in Proton’s telling — no logs, zero-access-encrypted history, and no use of chat data for training. (proton.me) ### Is this just email and docs(proton.me)is part of both Workspace tiers, and Proton’s business pages say calls can scale up to 250 participants on the higher-end plans. Proton also added appointment scheduling in Calendar and has been expanding Docs and Sheets, which is important because the old knock on Proton was that it had secure point products but not a complete work environment. (proton.me) ### What are the actual plans? Workspace Standard s(proton.me) month to month. Workspace Premium starts at $19.99 annually, or $24.99 monthly. Premium adds more storage, email data retention policies, higher Meet limits, and Lumo. That pricing tells you who Proton wants first — small and midsize teams that already pay for a patchwork of email, password, storage, and meeting tools. (proton.me) ### Why is retention policy a big detail? Because this is(proton.me) starts sounding like software for actual companies. Data retention controls are boring, but they are load-bearing for regulated teams — legal, finance, healthcare, compliance-heavy shops. Proton is trying to say you do not have to choose between strong privacy and the admin controls businesses need to run audits, preserve records, and manage risk. (proton.me) ### What changed versu(proton.me)e full bundle. Since then it has added private AI, encrypted spreadsheets, video calling, and more business-oriented workflow features, then wrapped them into a single Workspace plan. So the real news is not one app. It is that Proton now thinks its ecosystem is complete enough to be sold as a serious replacement, not just a safer add-on. (proton.me) ### Bottom line? Proton is betting that the next workplace software(proton.me) If Google and Microsoft sell convenience plus AI context, Proton wants to sell a different promise — your company’s email, meetings, files, and AI chats stay yours.
