Valurian provides verifiable, secure file transfers with full integrity and auditability

Modern compliance standards demand more than “it was sent.” You need proof that files weren’t altered, that access was controlled, and that the whole process was logged.
Valurian gives you verifiable file transfers with cryptographic hashing, role-based access controls, and audit logs. All built in, no third-party tools required.

Compliance requires more than just “Sending a file”

Traditional file transfer tools move data but they don’t prove anything. If you’re responsible for security, compliance, or chain of custody, you need more than speed.

Let’s break it down:

  • No file integrity checks
    Most tools skip validation, so you don’t know if the file was altered, truncated, or corrupted in transit.
  • No audit trail
    There’s no record of who sent what, when, or whether the transfer followed policy.
  • No role-based access control
    Any user can send anything to anyone because there is no approval workflow, no escalation, no oversight.
  • No compliance alignment
    Frameworks like GDPR, ISO 27001, ANSSI expect traceability. FTP and even most “modern” tools don’t deliver.
Capability Cloud-dependent Tools Valurian
File integrity verification ❌ Often missing ✅ Built-in, tamper-evident hashes
Audit trail / Logging ❌ Rare or partial ✅ Logged transfers + access history
Role-based access control ❌ Not enforced ✅ Integrated permissions and roles
Approval workflows ❌ Manual / External ✅ Supervisor-based workflow options
GDPR/ANSSI alignment ⚠️ Not designed for it ✅ Compliance-ready architecture
Centralized server required ❌ Usually ✅ Decentralized, node-managed

Valurian is designed for verifiability and built for compliance

Valurian doesn’t just move files. It proves that they moved, securely and correctly. Whether you need to meet internal security standards, satisfy external auditors, or ensure zero-tamper integrity, Valurian gives you full control and traceability out of the box.

Here’s how:

  • Cryptographic hashing on both ends
    Files are verified using SHA-256 hashes before and after transfer to guarantee end-to-end integrity.
  • Automatic audit logs
    Every transfer is recorded with timestamps, source/destination metadata, and outcome exportable for compliance teams.
  • Role-based access control
    Define exactly who can send, receive, or approve files and restrict access by group, role, or node.
  • Supervisor approval workflows
    Require manual validation or sign-off before sensitive data can move.
  • Immutable event trail
    Optional tamper-proof logging mechanisms provide strong guarantees for chain of custody and legal admissibility.
  • Built to support GDPR, ISO 27001, and ANSSI
    Valurian aligns with key compliance frameworks without the complexity of layering on external tools.

"You control the access. You verify the integrity. You prove the chain of custody."

What compliance teams ask before they sign off on Valurian

These are the critical questions we get from teams under GDPR, ISO 27001, and ANSSI mandates.

What makes a file transfer “verifiable”?

A verifiable transfer means you can prove the file wasn’t altered, intercepted, or tampered with.

Valurian uses end-to-end hashing and logs every transaction from sender to recipient.

Does Valurian log who sent what and when?

Yes. Every transfer is automatically logged with timestamps, source/destination info, and transfer outcome.

You can export these logs for compliance reporting or audits.

Can I restrict who’s allowed to send or approve files?

Absolutely. Valurian includes native role-based access controls and supervisor approval workflows.

You decide who can move what and enforce approvals where needed.

Is Valurian compliant with GDPR or ISO 27001?

Yes. Valurian supports secure data handling practices aligned with GDPR, ISO 27001, and ANSSI recommendations.

It’s built for regulated and high-assurance environments.
