Zivver launches Private Data Network: Sovereign control over sensitive data

Unique Kiteworks platform provides full autonomy for secure file sharing, collaboration and communication

The demand for true sovereign control over data is growing rapidly. Organizations want absolute certainty that only they - and no one else - can access their confidential information. This need is driven not only by geopolitical risks, but also by stricter regulations like NIS2 and growing dependence on non-European cloud providers. 

Whether it's sharing sensitive project files with external partners, receiving medical or legal information via web forms, sending confidential reports via email, or collaborating on documents with colleagues across locations - secure digital data exchange is now essential to day-to-day operations. 

While more and more organizations are moving toward private cloud infrastructure or self-hosted environments, they often lack the software needed to manage these processes securely, efficiently, and in a compliant way. Traditional solutions frequently fall short when it comes to access control, end-to-end encryption, zero-trust architecture, or user-friendly collaboration features and/or organizations need to use different point solutions for various use-cases resulting in high costs and lack of uniformity. 

That's why Zivver and Kiteworks are introducing the Private Data Network (PDN): the unique integrated platform that delivers complete data sovereignty, maximum security, and full compliance support, for all forms of sensitive data exchange, including file sharing, MFT, secure email, web forms, and real-time document collaboration. 

Data Sovereignty - Cloud, On-Premises, Hybrid or Airgapped Deployment

The Private Data Network offers a unique combination of functionality and sovereign management. All from an environment fully governed by the organization - regardless of whether it runs in the cloud, on-premises, or in a private cloud. 

Crucially, the PDN is designed so that organizations retain full sovereignty over their data - even in hosted deployments. Thanks to Bring Your Own Key (BYOK), encryption keys remain solely under the control of the customer. As a result, data cannot be accessed under the U.S. Cloud Act, even if the infrastructure is hosted in a public cloud. Please see this article that details the real risks of the US cloud - and how to mitigate them. 

For organizations that also want to mitigate risks related to service continuity or foreign legal exposure, the PDN can be fully deployed on-premises or within a private cloud located inside their own legal jurisdiction, ensuring that both the data and the infrastructure remain fully under national or organizational control. 

The PDN can also be deployed in a completely airgapped mode - fully disconnected from the internet - for the highest level of operational isolation, ideal for classified environments, critical infrastructure, or defense use cases. 

Only sovereign total solution for sensitive data exchange and communication 

While secure file sharing and email encryption solutions exist, the Private Data Network is the only solution that integrates all of these features into a single platform, including: 

✅ Secure File Sharing: with expiration, access control, DLP, encryption, logging 
✅ Document Collaboration: Real-time editing in the browser without files leaving the platform 
✅ MFT & SFTP: Automatically exchange large amounts of data and files of large size between systems via various protocols, including EDI/AS2. 
✅ Secure Forms: for sensitive data ingestion of clients or partners 
✅ Secure Email: Secure email storage and delivery with support for S-MIME and PGP

All within a hardened zero-trust architecture, with the highest international security standards. 

Why PDN is more secure than other solutions 

While many organizations use platforms such as Microsoft 365 (SharePoint/OneDrive), Google Drive,  or Nextcloud, they are not designed to handle strictly confidential information securely and compliantly.

In short: the Private Data Network is the only solution that integrates collaboration, file transfer and e-mail in a secure, sovereign and compliant platform. 

Proven technology with highest certifications 

The Private Data Network is built on hardened, enterprise-grade technology and enhanced with advanced security, compliance, and integration capabilities from Kiteworks. As a result, it helps organizations meet the strictest international compliance requirements, including: 

• CMMC 2.0

• FedRAMP High

• SOC 2 Type 2

• ISO 27001, 27017, 27018

• GDPR, NIS2 and DORA 

There's no more secure - that's why PDN is now used by more than 3,600 organisations worldwide, including: 

• Military and national defence organisations

• Intelligence and security services

• Large multinationals with a lot of business-sensitive information

• Government agencies and critical infrastructure

These organizations consciously choose a solution in which no third-party power, no supplier and no cloud provider can ever enforce access to their data. 

Fast and Flexible Deployment - in Weeks, Not Months

Migrating to the Private Data Network is far easier than many organizations expect. While some assume such secure, sovereign infrastructure takes 6 to 12 months to implement, the PDN is designed for rapid, phased deployment - often going live within a few weeks. 

Whether hosted, on-premises, or hybrid, PDN can be integrated seamlessly into your existing environment. It supports: 

• Out-of-the-box connectors for Microsoft 365, email gateways, and storage solutions

• Granular configuration options to match organizational policies

• Step-by-step adoption, allowing teams to start with one use case (e.g. secure file sharing) and expand as needed

• Full support from experienced engineers who’ve onboarded thousands of secure environments worldwide

In short: PDN is not a 12-month IT overhaul, but a fast-track path to sovereign security - with measurable value in weeks, not years. 

Who is this for?

The PDN is ideal for organizations that: 

• Working with sensitive or strictly confidential data

• Wanting to comply to GDPR, NIS2, DORA, CMMC and other regulations

• Wanting to protect themselves from cloud dependency

• Want to make sure that only they have access to their information
