The Swiss-engineered platform that’s proving you don’t need a computer science degree to achieve zero-knowledge security, transforming complex encryption into surprisingly intuitive file sharing with European privacy standards and bulletproof protection
Executive Summary
Product Name & Vendor:
Tresorit by Tresorit AG, founded in 2011 by István Lám, Szilveszter Szebeni, and György Szilágyi in Budapest, Hungary. The company emerged from the founders’ recognition that existing cloud storage solutions didn’t provide adequate security for sensitive business and personal files. Founded by experienced computer science graduates who understood both the technical challenges of encryption and the user experience needs of modern businesses, Tresorit pioneered client-side zero-knowledge encryption technology. In 2021, Swiss Post Communications Services acquired the company to expand its digital portfolio, with Tresorit now operating as an independent entity under Swiss ownership. The platform has grown to serve over 11,000 organizations worldwide across offices in Zurich, Switzerland; Munich, Germany; and Budapest, Hungary, focusing on providing enterprise-grade security that remains accessible to non-technical users.
Quick Overview:
Tresorit is a comprehensive, end-to-end encrypted cloud storage and collaboration platform designed for businesses and individuals who need complete security for sensitive files without sacrificing usability. Unlike traditional cloud storage that only encrypts files during transfer or storage, Tresorit works as an intelligent zero-knowledge platform that encrypts files directly on user devices before they ever leave, ensuring that only authorized recipients can decrypt them. The platform combines secure file storage, encrypted collaboration, electronic signatures, and data room functionality through intuitive web and mobile applications that provide enterprise-level security with consumer-friendly simplicity.

Fun Fact
Tresorit’s founders were so confident in their zero-knowledge encryption that in 2013 they launched a public hacking contest offering $50,000 to anyone who could break their security. This was essentially putting a bounty on their own heads while challenging cybersecurity experts from Harvard, Stanford, and MIT to prove them wrong.
The contest ran for 468 days straight – over 15 months of continuous public challenge. During this time, the founders likely monitored their systems closely, wondering if each day would bring someone who could claim their $50,000 and potentially damage their business model.
After more than a year of inviting the world’s best hackers to attempt breaking their encryption, nobody succeeded. This public challenge proved that their security claims weren’t just marketing statements but had been tested under real pressure from motivated experts.
Today, Tresorit remains one of the few major cloud storage companies to have survived such a prolonged public security challenge. Their approach of literally paying people to try to disprove their security claims may have been an expensive way to demonstrate their encryption strength, but it provided convincing evidence that their zero-knowledge architecture could withstand serious attack attempts.
This strategy transformed their “unhackable” marketing claims into verifiable statements backed by an extended public testing period where financial incentives attracted genuine attempts to break their system.
