- Proton expands its privacy ecosystem by offering secure and transparent AI tools
- Lumo for Business arrives three months after its debut with improved speed and performance
- Private AI assistant protects company data via zero-access encryption
Best known for its encrypted email and VPN services, Proton has launched Lumo for Business, a generative AI assistant to help businesses take advantage of the productivity benefits offered by AI without the risk of accidentally exposing confidential information.
Over the past few years, generative AI has disrupted the way employees do their daily work, from writing and coding to research and reporting.
However, popular AI tools like ChatGPT and Gemini have raised 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 doesn’t keep logs or share user information.
Built on the same foundation as Proton Mail and Proton VPN, Lumo for Business allows employees to write documents, analyze information, and collaborate securely.
It integrates with Proton Drive, so teams can add files directly into AI conversations for better context.
Hosted entirely in Europe and GDPR compliant, 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 U.S.-based AI platforms that could be forced to share user data under government orders.
“Generative AI has changed everything and is likely to create the biggest societal shift since the creation of the Internet itself. This is true for consumers, but perhaps even more so for businesses. AI assistants increase productivity and are already prevalent in the workplace. But they carry serious risks,” said 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 businesses don’t have the resources to build their own ChatGPT from scratch. That’s the void that Lumo fills. Companies shouldn’t have to choose between competitive advantage and data security. With Lumo, they get both: enterprise-grade AI that protects their sensitive data,” he added.
Three months after Lumo’s debut, Proton has enhanced the service with performance and speed updates and is now making it widely available through the Lumo website and apps for iPhone or Android.
