Ephemeral by default. Persistent by choice.

Choose the right file model

Not every file product is solving the same problem. Some are built for live delivery, some for persistent encrypted storage, and some for stored pickup later. PhotonFile includes both Relay and Vault, so the right choice depends on what you want to happen after the file is sent.

PhotonFile Relay

Ephemeral File Transfer

Best when both people are online and the goal is delivery, not retention. PhotonFile relays data live through encrypted memory and operates ephemerally by default.

  • Live sender-to-recipient relay
  • Memory-only handling during active transfer
  • Optional client-side encryption
  • Resumable behavior in supported environments
Photon Vault

Persistent encrypted storage

Best when files need to remain available after upload, when you need to receive files safely from outside users, or when the workflow is upload now and access later. Photon Vault is client-side encrypted storage built for long-term retention, collaboration, scoped sharing, versioning, and Secure Inbox.

  • Persistent encrypted storage
  • Vault-based security boundaries
  • Scoped sharing and Secure Inbox
  • Versioning, team access, and async handoff workflows
Stored delivery

Storage-based delivery

A common upload-now, download-later workflow. Photon Vault can handle this too, but traditional transfer tools usually stop at a hosted stored link instead of adding persistent encrypted storage.

  • Upload now and let the recipient download later
  • Hosted link pickup is the default pattern
  • Usually centered on time-limited retention
  • Vault can cover this workflow with stronger storage controls

Choose by intent

Need Best fit Why
Both users are online and the file should not remain stored by default PhotonFile Relay Live, in-memory relay designed for ephemeral delivery.
Files need to stay available after upload Photon Vault Persistent client-side encrypted storage with sharing, versioning, and secure inboxes.
Someone needs to upload now and the recipient or team can review or download later from an encrypted destination Photon Vault Vault supports async handoff without reducing the workflow to a generic stored transfer page.
Recipient will pick up a stored copy later from a hosted link or encrypted destination Photon Vault Vault fully supports upload-now, download-later workflows while adding persistent encrypted storage, sharing, and access control.
Need stronger privacy over who can decrypt stored files Photon Vault Encryption happens on the client before upload and authorized clients decrypt later.
Need to safely collect uploads from outside users Photon Vault Secure Inbox isolates inbound uploads from existing vault contents.

Compare by outcome

What matters most is what happens to the file after upload. Relay is built for live delivery when both sides are online. Vault is built for the broader platform job: secure intake, async handoff, controlled sharing, and long-term encrypted storage. Traditional stored-delivery tools are just one version of that workflow.

Choose the outcome you need: live delivery with Relay, or Vault for upload-now access-later, receiving files, sharing securely, and persistent encrypted storage in one system.

Encrypted-at-rest is not the same as client-side encrypted storage

In a stored-delivery model, the provider commonly manages the storage layer and retention policy. That may protect the storage media, but it does not automatically mean the provider lacks access to decrypted content.

  • Stored delivery implies a retained copy for some period
  • Client-side encryption keeps key control closer to the user
  • Vault and Relay solve different privacy problems
