- 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
- AI Private Assistant Protects Business Data Using Zero-Access Encryption
Proton, best known for its VPN and encrypted email services, launched Lumo for Business, a generative AI assistant to help businesses enjoy the productivity benefits that AI offers without the risk of accidentally exposing sensitive information.
In recent years, generative AI has changed the way employees complete 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 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 draft documents, analyze information, and collaborate securely.
It integrates with Proton Drive, so teams can add files directly to AI conversations for better context.
Hosted entirely in Europe and GDPR compliant, the service is built on 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 will create the biggest social change since the creation of the Internet. 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,” said Eamonn Maguire, Director of AI Engineering at Proton.
“Many companies have already banned ChatGPT and we are 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 gap that Lumo fills. Businesses shouldn’t have to choose between competitive advantage and data security. With Lumo, they get both: enterprise-grade AI that keeps their sensitive data safe,” he added.
Three months after Lumo’s initial debut, Proton improved the service with performance and speed updates and is now making it widely available through the Lumo website and apps for iPhone or Android.
