# Sealed networks, big files and clinics.

Government networks with no outside connection, multi-gigabyte footage, and patient files between clinics.

Defense & government

## Sharing across a network with no outside connection, by design.

The challenge.Air-gapped and other network-restricted environments cannot use cloud storage or email attachments at all, but staff still need to move files between approved machines.

With Privatta.Run Privatta entirely on the LAN with no internet connection at all. Machines discover each other automatically, every transfer is TLS-encrypted, and an immutable local log records exactly who accessed what, satisfying review without any external dependency.

- Works on a LAN with no internet connection at all
- Choose which address ranges each machine will fetch from
- Local, tamper-evident access log covering LAN and internet sessions

Media & production

## Moving multi-gigabyte files without a cloud upload tax.

The challenge.Raw footage and project files are large, sensitive pre-release, and uploading to a shared drive for a single handoff wastes hours and bandwidth.

With Privatta.Producers and editors transfer directly, machine to machine, at local network or direct-internet speed — no upload-then-download round trip, and no copy sitting on a third party's storage while a cut is still unreleased.

- Direct transfer at full link speed
- No file size limits imposed by a cloud tier
- Files never touch a third-party server

Healthcare

## Sending patient files between clinics without a BAA.

The challenge.Sharing imaging or records between practices usually means a cloud service — and a Business Associate Agreement, a data-processor relationship, and a new attack surface.

With Privatta.Because transfers are direct and end-to-end encrypted with no relay, there is no third party in the data path at all. Per-user access control and a local audit log support compliance review without adding a vendor.

- No cloud intermediary, no BAA to negotiate
- Per-user file permissions
- Full local access log for compliance
