Secure File Delivery

Move large datasets between businesses, fast and audited.

Designed for studios, regulated industries and research grids — anywhere arbitrarily large files need to cross the internet without going through public cloud egress.

Resumable uploads

Multi-TB transfers survive flaky links, broken sessions and laptop lids. Resume from any chunk boundary.

Integrity by design

Every chunk is BLAKE3-hashed at the client and verified at every hop. No corrupt frames reach the recipient.

Audit-ready

Per-transfer signed manifests (HSM-backed Ed25519). Exportable as PDF or signed JSON for compliance.

How a transfer looks

Two endpoints, one delivery. Either side can be a person, an office, a build server or a storage cluster.

# Example: upload from a CI runner
$ isr-cli upload \
    --to acme-frankfurt \
    --tenant acme-eu \
    --key ~/.isr/tenant.key \
    --resume \
    ./rushes/Day14_*.r3d

All prices ex. VAT. Onboarding requires a short due-diligence call and KYC. We do not accept anonymous accounts.

Access to the delivery endpoints is restricted to authenticated tenants. The public web does not host an upload form — please use the Client Portal or the isr-cli tool with your tenant key.
