Why firms move off email

Confidential documents deserve better than an attachment

Email was never designed to carry privileged material. Vaultline replaces the attachment with a controlled exchange that you can govern, evidence and revoke.

Encrypted exchange

Files are encrypted with AES-256 at rest and travel over TLS 1.3. Keys are managed in an EU-resident HSM-backed store and rotated on a fixed schedule — not by hand.

Granular permissions

Decide per person, per folder and per file: view, download, print or nothing at all. Change your mind at any point and the access disappears — including on files already delivered.

Complete audit trail

Every upload, view, download, permission change and expiry is written to an append-only log with actor, timestamp and IP. Export it as evidence whenever a regulator, client or court asks.

No attachment size limits

Send a single file up to 100 GB, or a 4,000-document bundle, without touching anyone's mailbox quota. Recipients get a link, not a payload.

How it works

Three steps, no software for your counterparties

Step 1

Create a room

Spin up a secure room from a template — due diligence, disclosure, audit request, tender. Folder structure, permission tiers and retention rules come pre-set.

Step 2

Invite the right people

Add counterparties by email address or domain. Assign a role, set an expiry date, and choose whether documents can leave the room at all.

Step 3

Watch, evidence, close

See who read what and for how long. When the matter closes, archive the room to a sealed record or let the retention policy dispose of it automatically.

Built for regulated work

Evidence, not assurances

When a client asks who saw a document, "we think only the deal team" is not an answer. Vaultline is designed so the answer is a timestamped record you can hand over.

  • Append-only activity log covering every object in the account
  • Per-recipient dynamic watermarking on view and print
  • Retention schedules that dispose on time, with a disposal certificate
  • Legal hold that overrides deletion until a matter closes
  • SAML SSO, SCIM provisioning and enforced MFA on Enterprise

Read our security and compliance posture

“We used to run disclosure through a shared mailbox and a courier for anything over 20 megabytes. Now the bundle sits in one room, the other side's access expires when the deadline passes, and I can produce the access log without asking IT for anything.”
