  • Expiring links — set duration from one hour to thirty days
  • Password protection — optional extra layer of security
  • No account needed — recipients open the link and download
  • Track downloads — see who accessed your files and when
  • Security
    Encrypted in transit

    Enterprise-grade protection with TLS 1.3 encryption for every file you share.

Shared Folders

Shared Folders

When you need an ongoing shared space — not just a one-off link — Shared Folders give your team a persistent home for files. Think Google Drive or Box, but built into your Fastio workspace with no per-user fees.

  • Persistent shared space — files stay organized and accessible long-term
  • Member permissions — control who can view, edit, or manage each folder
  • Desktop app sync — work offline and sync changes automatically when you reconnect
  • Invite externals — bring in clients or partners without exposing the rest of your workspace
Portals

Portals

When you need more than a link or a folder, Portals give your clients a branded, professional destination to access files, documents, and deliverables. Your logo, your colors, password protection, and audit trails built in.

  • Fully branded — your logo, colors, background, and custom domain
  • Password protected — control exactly who can access your portal
  • Audit trails — see who accessed what and when, every visit logged
  • No account needed — clients access via link, no sign-up required

Custom Domain

Custom Domain

Every share link and shared folder can live on your own domain. When clients receive a file or access a folder, the URL carries your brand, not ours. It looks like something you built yourself.

Branded Share Links

Quickshare links use your custom domain. Send a file via files.yourbrand.com instead of a generic URL.

Shared Folder Domains

Persistent shared folders live on your domain too. Clients bookmark and revisit a URL that reinforces your brand every time.

Automatic SSL

SSL certificates are provisioned automatically. Your custom domain is secure from the moment you connect it.

Access Control

Secure by Design

Sharing files shouldn't mean losing control. Set boundaries on who, when, and how your files can be accessed.

RESTRICTIONS

Passwords & Expirations

Lock down sensitive links with passwords, and set them to auto-expire after a certain date or number of downloads.

MODES

Send, Receive, Exchange

Choose exactly how guests interact with your share. Allow them to only download (Send), only upload (Receive), or both (Exchange).

HIERARCHY

Granular Permissions

Control access down to the specific file or folder. Give some users edit rights while restricting others to view-only.

COLLABORATION

Guest Access

Share securely with external collaborators. They can view, upload, or download based on your rules, without needing a Fastio account.

COMPLIANCE

Complete Audit Trails

Every view, download, and modification is permanently logged. Always know exactly who accessed your data and when.

GOVERNANCE

Ownership Transfer

Agents can build a workspace and cleanly transfer full ownership and billing responsibility to a human team member.
