Proton Launches Lumo for Business Bringing Privacy First AI to Secure Enterprises

Proton, known for their staunch commitment to privacy and digital security, is making big strides into the world of AI with the release of Lumo for Business. Expanding from its earlier version of the AI assistant Lumo, this new platform is specifically tailored for organizations that demand top-tier confidentiality, compliance, and efficiency within their operations.

With the unveiling of Lumo for Business, Proton is poised to bridge the gap between AI-driven productivity and enterprise-level data protection-a combination rarely found in today's AI-dominated landscape, which features so many data-hungry systems.

Built for Businesses That Value Confidentiality

Lumo for Business has been designed to meet the needs of vertical industries that rely on discretion and trust, including financial advisers, legal professionals, and technology companies with highly sensitive intellectual property or client data. With Proton's focus on privacy-first AI, these organizations can harness the power of artificial intelligence without sacrificing security.

Unlike most AI platforms, which retain or analyze the interactions for performance improvement, Lumo never retains any record of conversations. Further, all communications by team members are secured with zero-access encryption, meaning even Proton is unable to view or decrypt this information. This way, only the end-users control their data — not servers or developers behind the product.

Full Data Control and Open-Source Transparency

Proton's promise of privacy goes further than encryption. The company states that business data shared with Lumo, including sensitive information like intellectual property, confidential documents, and client discussions, remains completely within user control. This can be especially important for organizations operating under highly regulated frameworks or handling proprietary information which cannot afford to be exposed.

To further reinforce trust, Proton has made all versions of Lumo (web, iOS, and Android) fully open source. This allows independent security researchers and IT professionals to audit the code, ensuring transparency and accountability. Few AI providers offer this level of openness, making Proton’s approach a standout example in ethical AI development.

Designed for Security, Powered by Accessibility

While Lumo for Business focuses on robust privacy features, Proton has also placed an emphasis on usability and cross-platform accessibility. This AI assistant is fully accessible across devices, whether one is on a desktop at the office, a tablet during travel, or a smartphone on the go.

With Proton, teams stay not only connected but also efficient and secure, no matter where they work, because functionality remains consistent across platforms. That's exactly the point of the company's design philosophy: privacy should never come at the cost of convenience.

Pricing and Availability

Proton is proud to announce that Lumo for Business is now available to all organizations worldwide. Pricing is simple, clear, and adaptable to fit the needs of small and large enterprises alike. Business subscriptions are available at €23 a month with an annual plan, or at €28 month-to-month.

Considering Proton's standing and the increasing demand for privacy-compliant AI tools, this pricing is highly competitive, especially in view of the end-to-end encryption, open-source transparency, and enterprise-grade control of the platform.

With Lumo for Business, Proton is pushing the boundaries of what privacy will mean in the AI age. While more and more companies are embedding AI into their workflows every day, so are the risks of exposure, leakage, and misuse of data. Proton's move creates a new threshold for ethical and secure AI deployment: a guarantee that at no point will innovation compromise confidentiality.
