Heavy transfers that just work.

No. Files travel directly between computers over an encrypted channel. ZettaSend coordination servers facilitate the initial handshake, but they never inspect, store, or process your file contents. If a direct peer-to-peer path is blocked, encrypted packets route through fallback relays without the relay ever holding the decryption keys.

Yes. Because files stream directly between machines without sitting on intermediary servers, both workstations must remain powered on. ZettaSend automatically prevents your computer from sleeping during active transfers, lets you throttle bandwidth to protect active work, and resumes seamlessly if an application is closed.

ZettaSend handles connection drops with automatic network recovery. Transfers pick up at the exact byte where they stopped without corrupting files or forcing you to restart the transfer from zero.

No. You can drop entire project directories, nested bins, and camera card structures straight into ZettaSend. The complete folder hierarchy is preserved byte for byte on the recipient storage drive.

Files stream directly to whatever target directory you select. You can write incoming media straight to high-speed NVMe scratch drives, RAIDs, or network-attached storage without filling up your system boot drive.

ZettaSend always attempts a direct peer-to-peer link first. If restrictive NAT or firewall rules block direct access, the transfer automatically falls back to our secure relay infrastructure. Packets remain fully encrypted end-to-end, and a clear status indicator informs you when a relay is active.

No. Torrenting is decentralized public distribution. ZettaSend is an enterprise-grade point-to-point pipeline. Your footage streams directly from your storage array to the recipient's machine inside an encrypted cryptographic wrapper, keeping your unreleased production assets completely isolated from public networks.

Browser tools are constrained by web sandboxes. Inactive tabs get throttled by the OS to save memory, tab memory limits cause crashes on heavy media batches, and accidentally closing the browser kills the entire session. ZettaSend is a native desktop application with direct disk streaming, persistent background transfers, automatic resume down to the exact byte, and zero file size caps.

When a transfer occurs on the Team plan, both the sender and recipient generate a cryptographic key pair and digitally sign a shared metadata contract directly on their devices. This records a unique transfer ID, timestamps, IP addresses, and a file manifest listing names and sizes. Because each party signs with their local private key, any post-transfer modification immediately invalidates the signature, providing workspace admins with tamper-evident proof for compliance and dispute resolution without ZettaSend ever seeing the contents of your files.

Yes. Team plan administrators can upload a custom logo and company name in settings. Your branding appears in session invite emails and inside the transfer interface for a consistent, professional client presentation.

Yes. On the Team plan, the workspace administrator can configure a webhook endpoint. The app calls it twice for every incoming transfer: once before it starts, where your code can approve or reject the delivery (enforcing naming conventions, file types, disk space, sender identity), and once after it completes, where you can trigger notifications, QC, transcoding, or asset database registration. When your endpoint rejects a transfer, the markdown message you return is rendered directly in the sender's app, so the person who sent the files sees exactly why the delivery was blocked and what to fix. File contents never leave the encrypted peer-to-peer channel.

No. ZettaSend is fully zero-config and runs natively on macOS, Windows, and Linux. It installs without administrator privileges, requires no port forwarding, and needs no local server management.

Yes. Recipients never need a subscription or account. You can share a web link that guides them through the quick setup step by step, or simply give them a connection code to start receiving files directly to their disk.
