Digital Trust: NetExplorer and Yousign Unify the Entire Document Chain in a Sovereign Cloud
In 2026, NetExplorer became Voltn.
Press release, February 2026 – NetExplorer, an expert in document management and sovereign cloud storage, and Yousign (soon to become Youtrust), Europe's leading digital trust platform, today announced a technology alliance aimed at simplifying and securing the management of organizations' sensitive documents. By bringing together document management, secure sharing and electronic signature within a single, unified and sovereign platform, the two companies enable CIOs to centralize the entire document lifecycle, reduce tool fragmentation and strengthen IT compliance.
Too many tools, tightening regulations: a challenge for CIOs
Between the proliferation of collaborative tools, the scattering of documents and increasingly strict regulatory requirements, IT departments must now balance risk control, ease of use and compliance. From creation to archiving, including electronic signature, document lifecycle management remains all too often fragmented — complicating IT governance and multiplying vulnerabilities.
A single platform to regain control of the document lifecycle
The solution jointly developed by NetExplorer and Yousign offers a concrete answer: bringing together, within a single sovereign platform, all the building blocks organizations need to manage their documents. It notably enables:
- Centralizing documents (sharing, storage, validation and signature) within a single environment
- Reducing the risk of file loss, duplication or non-compliance
- Simplifying the IT landscape by limiting reliance on a multitude of disparate tools
- Native compliance with current standards and regulations (eIDAS, ISO 27001, HDS)
"In the age of AI, digital trust can no longer rely on a patchwork of tools. Companies need platforms capable of securing the entire document chain, from identification to signature, while guaranteeing sovereignty, compliance and ease of adoption," says Alban Sayag, CEO of Yousign.
Native integration with existing IT systems, no disruption required
The integration is built on advanced interoperability between the NetExplorer and Yousign platforms. Documents are stored, shared, validated and signed without ever leaving a certified sovereign environment, guaranteeing the integrity of the entire chain. Thanks to an API-first approach, the solution integrates easily with existing business applications and adapts to organizations' internal processes, without requiring any changes to their IT architecture.
"For a CIO, the challenge is to have a reliable, secure platform that is simple to integrate, capable of protecting critical document flows without adding complexity. NetExplorer has always designed document management and sovereign cloud storage solutions tailored to sensitive environments. This partnership with Yousign takes things even further, natively embedding legal proof at the heart of the document," says Bertrand Servary, CEO of NetExplorer.
Signature, workflows, traceability: a solid functional foundation
A true document control tower, the platform supports even the most demanding processes thanks to:
- Three levels of eIDAS electronic signature (simple, advanced and qualified)
- Automated validation workflows, including approver management and reminders
- Complete traceability, pairing legal proof with the document to guarantee the authenticity and integrity of exchanges
