Data security

Your data, protected at every step

Voltn (formerly NetExplorer) secures your files from end to end with isolated infrastructure, robust encryption, and real-time threat detection. A single team manages every link in the chain, from code to hosting.

Sovereign infrastructure, from code to hosting

Your files are hosted in two Tier 3+ and Tier 4 data centers located in the Paris region. This dual-site setup guarantees over 99.995% availability and real-time backup across two distinct locations. Voltn develops and operates its entire solution: no critical components are entrusted to third parties outside our control.

Resilience and availability

Our architecture is designed to withstand incidents. Nothing is left to chance.

Strict environment isolation

Each organization has an independent partition. If one service is compromised, the others remain protected: no attack can spread from one client platform to another.

Real-time replication and backup

Every file is replicated in real time across three storage clusters, one of which is located 30 km from the main site. In the event of a major incident at a data center, your data remains available at the second site.

30 days to roll back

Any deleted file remains recoverable for 30 days, even in the event of an accidental deletion of an entire directory tree.

Access protection: every connection is verified and tracked


Enhanced authentication

Whether using a username and password, SSO linked to your corporate directory, or two-factor authentication via OTP, SMS, or Yubikey, you choose the level of friction that suits your organization.

Intrusion attempt detection

An abnormal number of login attempts triggers an automatic ban for the associated ID and IP address.

Custom access policies

Restrict access by user group, IP address, or time slot. You decide who connects, from where, and when.

Protected sessions

CSP, HSTS, and CORS headers prevent session hijacking and identity theft. The result: a perfect 100/100 (A+) score on the Mozilla HTTP Observatory Report.

Encryption and anti-ransomware: your files are protected before, during, and after transfer

‍

1

End-to-end encryption

All data exchanged with Voltn is encrypted via TLS with a 2048-bit key. Our implementation receives an A+ rating from SSL Labs.
2

Antivirus and ransomware detection

Every file uploaded to the platform is scanned, including those received via an external upload link. Heuristic analysis detects ransomware attempts, automatically disables the source account, and alerts administrators.
3

Anonymized storage

Files are stored in binary format, independent of their actual directory structure. Names and extensions are hidden: even in the event of unauthorized access to the raw storage, the content remains unreadable.

Traceability, a complete history of every action

Logins, additions, modifications, deletions: every action is recorded in searchable and filterable event logs. In the event of an incident, you know exactly who did what, and when.

How does Voltn secure your data?

What happens if a file is accidentally deleted?

It remains restorable for 30 days thanks to real-time replication across multiple storage clusters.

Can I track who accesses my files, and when?

Yes. Every action (login, addition, modification, deletion) is recorded in event logs that can be filtered by user, date, or action type.

What is a siloed cloud and why does it enhance security?

A partitioned cloud isolates each organization within an independent compartment. If an application or service is compromised, other client platforms remain protected.

What encryption does Voltn use to secure my files?

All data exchanged with Voltn is encrypted via TLS using a 2048-bit key, an implementation rated A+ by SSL Labs.

How does Voltn protect my data against ransomware?

Every file uploaded to the platform is scanned, including through external upload links. Heuristic analysis detects ransomware attempts, automatically disables the source account concerned and alerts administrators.
