Zug, Switzerland, 20. September 2021 – Vereign SEAL is the world’s first blockchain application used to preserve an email’s digital provenance. It is now available as an add-on to the VNClagoon communication and collaboration platform.

Every day, more than 300 Milliarden E-Mails are sent worldwide, many of them to multiple recipients. Today, practically no company can function effectively without this channel of communication. This makes it all the more important to ensure digital provenance, i.e., the authentic, verified origin of an e-mail.

VNC, a leading developer of open-source enterprise applications, now uses Vereign SEAL (Secure Electronic Authentication Layer) on its communication and collaboration platform VNClagoon. Based on blockchain technology, a seal is attached to each email in the form of a QR code that can be verified by any mail client or server that supports Vereign SEAL.

Other functional modules of the collaboration stack, such as messaging or ticketing, will follow. VNC and Vereign are working together to successively integrate Vereign SEAL into all core VNClagoon applications, such as VNCchannel, VNCtalk or VNCgroupware, to make digital provenance widely available beyond email.

“The integration of Vereign SEAL into VNClagoon is an exciting project,” emphasizes Andrea Wörrlein, Managing Director of VNC in Berlin, Germany and Board Member of VNC AG in Zug, Switzerland. “It exemplifies how blockchain technology can help make the digital world a more comprehensively secure place and at minimal cost.”

“Digital provenance is becoming a critical factor for many companies,” explains Claus Bressmer, Managing Director at Vereign. “Security and compliance policies mandate it in an increasing number of countries, but it cannot be met with local platforms or proprietary, client-specific solutions. The solution is the Vereign SEAL.”
