Tresorit provides an end-to-end encrypted productivity solution for collaboration, including managing, storing, syncing, and transferring files. Tresorit’s technology combines industry-leading end-to-end encryption, granular data control features, and seamless integration into workflows.

Founded in 2011, Tresorit cites that it's mission is to empower everyone to take back control of their digital valuables by protecting their privacy and confidential information. The company closed an €11.5M Series B financing round in 2018 and was featured on FT1000 by Financial Times 2020[1] as the fifth fastest-growing cybersecurity company in Europe.

he software is available for Windows, macOS, Android, iOS, and Linux, and the company has released plugins for Gmail and Outlook. As of 2022, Swiss Post owns a majority stake in the cloud storage service. Tresorit works as an independent entity under Swiss Post.[2] The company has offices in Zurich, Switzerland; Munich, Germany; and Budapest, Hungary, employing around 100 people.

History

Tresorit was founded in 2011 by Istvan Lam (CEO), Szilveszter Szebeni (CIO) and Gyorgy Szilagyi (CPO). In the coming years, Andrea Skaliczki joined as CFO, Istvan Hartung as CTO and Arno van Züren as CSO. The company officially launched its client-side encrypted cloud storage service after emerging from its stealth beta version in April 2014.

In August 2015, Wuala (owned by LaCie and Seagate), a pioneer of secure cloud storage, announced it was closing its service after 7 years and recommended its users choose Tresorit as their secure cloud alternative.[3]

In 2016, Tresorit launched a beta of the software development kit (SDK) ZeroKit.[4] In January 2017, Apple's SDK project CareKit announced the option for mobile app developers using CareKit to integrate ZeroKit, enabling zero-knowledge user authentication and encryption for medical and health apps.[5]

In 2017, Tresorit patented its shareable encryption technology in the US under no. US 9563783 B2, and LogMeIn co-founder Marton Anka joined Tresorit as an investor and advisor.

In 2018, Tresorit received the ISO 27001 certification,[6] further demonstrating its commitment to information security as well as raised €11.5M Series B funding.[7]

In 2019, Tresorit reached the number of 100 employees, and Tresorit improved its governance feature set with e-mail verification and detailed user reports.

In 2020, Tresorit was named the 2020 Gartner Peer Insights Customers’ Choice for Content Collaboration Tools,[8] and retained the title in 2021.[9]

In 2021 released a set of features for external collaboration called Tresorit Content Shield[10][11][12]. New features included Advanced Link Tracking, Dynamic Watermarking, and Link Activity Reports.

In July 2021, Tresorit was acquired by the Swiss Post[13] to further expand its presence in its core German-speaking markets, including Germany, Austria, and Switzerland.

Technology

Tresorit can improve a company's security[14] by protecting files with AES 256 encryption. With Tresorit’s end-to-end encryption, every file and relevant metadata on user devices are encrypted with unique, randomly generated encryption keys. These keys are never sent to Tresorit’s servers in an unencrypted format. Accessing files is only possible with a user's unique private decryption key.

Tresorit uses random keys for each file and random IVs for each version of a file. The company claims that two identical files look completely different after encryption, thus they cannot be compared or matched.

Due to its zero-knowledge system,[15] Tresorit does not store passwords, only the user can access his/her own password. Administrators of a business Tresorit account can reset passwords in exceptional cases but can never access those.

Hacking contest

In 2013 and 2014, Tresorit hosted a hacking contest offering $10,000 to anyone who hacked their data encryption methods to gain access to their servers.[16] After some months, the reward was increased to $25,000 and later to $50,000, challenging experts from institutions like Harvard, Stanford or MIT.[17][18][19] The contest ran for 468 days and according to the company, nobody was able to break the encryption.[20]

Awards

In 2017, Tresorit was named one of the Rising Stars at Deloitte’s Technology Fast 50 Central Europe Award.[21] In 2019, Tresorit was named as a Global Leader in Cloud Computing at the Stratus Awards.[22] In 2020, Tresorit was named a 2020 Gartner Peer Insights Customers’ Choice for Content Collaboration Tools[23] and was featured on FT1000 by Financial Times 2020 as the fifth fastest-growing cybersecurity company in Europe.[24]
