Trusted for good reasons.
VNClagoon serves organisations where data sovereignty isn't a feature — it's the baseline. Tens of thousands of secure conversations, millions of encrypted emails, every day.
DFB GmbH
Sports & Media“VNC and DFB GmbH have been working together intensively for many years. We want to continue and expand this. The DFBnet mailbox developed and implemented by VNC has enormously accelerated and simplified our internal communication. With this, we see ourselves well prepared for future requirements.”
50,000+ mailboxes. Encrypted internal communication for the German Football Association and all member clubs. Migrated to sovereign cloud with zero data leaving the VNC-controlled environment.
Intel
Silicon & AI“VNClagoon combined with Intel OpenVINO™ and Intel Confidential Computing is the perfect match to elevate your communication and collaboration efforts. Together, Intel and VNClagoon help you get the most out of your hardware infrastructure.”
High-speed GenAI processing with security by design. VNClagoon's sovereign AI stack runs on Intel Gaudi accelerators — local inference, no cloud dependency.
Lenovo
Enterprise Infrastructure“Achieving tangible improvements for regulated industries. By deploying VNClagoon on Lenovo infrastructure, organizations eliminate data silos and ensure responsible adoption in critical sectors. The joint solution from Lenovo, Intel®, and VNClagoon delivers a modular, secure, and open-source based enterprise suite for communication and collaboration, covering email, chat, video, files, tasks, and projects, with optional private AI.”

Fujitsu
Enterprise IT“The strategic IT partnership with VNC and VNClagoon as part of our eArchive4Future project has resulted in many benefits: cost savings, increased efficiency and access to the latest technologies. Through clear communication and a shared vision, a successful and productive partnership has emerged.”
Long-term archiving with AI-assisted prompting and low-code/no-code integration — running on sovereign VNClagoon infrastructure.
T-Systems Solutions for Research
Research IT“In a recent workshop, we were able to convince ourselves of the high professional competence of the VNC experts and the efficient methods of agile software development. We also determined how we can implement the integrated product stack combined with our competence in consulting our customers, implementing and operating tailor-made solutions for the scientific community. We see this as a great potential and strive to use these synergies for customer projects selectively in their infrastructure or as a hosted solution, for example from the Open Telecom Cloud (OTC).”
PR-COM
Communications“VNC challenges the software giants that are oppressing the market with their expensive, inflexible and uninventive proprietary solutions. It's time for open-source applications to finally replace them. We use VNC's collaboration tools ourselves, including VNCtalk and, most recently, VNCchannels. The tools have made the transition to working from home extremely easy. The comprehensive VNClagoon product suite is a real highlight in terms of functionality and operation.”

Vodafone Group
Telecommunications“My team and I are very thankful for being able to count on the professional and sophisticated VNC team. VNC has supported us with a series of important projects, always exceeding our high expectations.”
Professional-services partnership delivering hosted solutions for the telecommunications group.
THW
Public Sector“Working with data from the cloud has many advantages. Facilities to host that sort of information have to meet highest possible security requirements. VNCdatacenter, near Zurich, is located in a building that exceeds these requirements: antiseismic, redundant external power supply, redundant emergency power supply with a fuel reserve for 2 weeks, doubled battery power supply for 2 days, strict access controls, and internal access control for every single rack: here, important data is as safe as in Abraham's bosom.”
Vereign AG
Digital Trust“Building on our common beliefs in Open Source and privacy, we are truly excited about our new partnership with VNC bringing digital provenance to email and beyond – verifiable and sovereign.”
