- Proton expands its privacy ecosystem with secure and transparent AI tools
- Lumo for Business arrives three months after debut with improved speed and performance
- Private AI assistant protects business data via zero-access encryption
Proton, best known for its encrypted email and VPN services, has launched Lumo for Business, a generative AI assistant to help businesses enjoy the productivity benefits offered by AI without the risk of inadvertently revealing confidential information.
In the past few years, Generative AI has improved how employees do day-to-day work, from writing and coding to research and reporting.
But popular AI tools like ChatGPT and Gemini have sparked understandable privacy concerns because they operate as closed systems with limited visibility into how data is stored or shared.
Zero access encryption
Lumo’s solution to this problem is zero-access encryption, meaning only users can decrypt their conversations. Proton says it does not keep logs or share user information.
Built on the same foundation as Proton Mail and Proton VPN, Lumo for Business allows employees to create documents, analyze information and collaborate securely.
It integrates with Proton Drive so teams can add files directly to AI conversations for better context.
Hosted exclusively in Europe and compliant with GDPR, the service is built around privacy and data protection.
Proton’s AI models and codebase are open source, allowing anyone to verify their security.
This transparency sets it apart from US-based AI platforms that could be forced to share user data under government orders.
“Generative AI has changed everything and is poised to create the biggest societal shift since the creation of the internet itself. This is true for consumers, but possibly even more so for businesses. AI assistants increase productivity and are already widespread in the workplace. But they come with serious risks,” says Eamonn Maguire, Director of Engineering for AI at Proton.
“Many companies have already banned ChatGPT, and we’re seeing reports of multinational companies building their own in-house AI because they can’t risk their data disappearing into a black box. But small companies don’t have the resources to build their own ChatGPT from scratch. That’s the gap Lumo fills. Companies shouldn’t have to choose between both Lumo business and data security. sensitive data safe,” he added.
Three months after Lumo’s first debut, Proton has improved the service with performance and speed updates and is now making it widely available via the Lumo website and apps for iPhone or Android.
