Secure Workspaces & Data Rooms

A shared workspace for exactly the people you choose. And no one else.

An ongoing encrypted workspace where a verified group shares files and folders, every action logged, and access is yours to grant or revoke whenever you like.

This isn’t file sending. It’s the room the work lives in.

Files, Forms and Spaces solve three different problems. Here is where Spaces fits.

Files

Send a thing once

A one-off send to named recipients. A disclosure pack to opposing counsel, say.

This module

Spaces

An ongoing, shared workspace

A controlled space a verified group keeps working in. A legal matter, a client engagement, an M&A data room.

Forms

Collect a thing, one-way

Structured data gathered from many people. Know Your Customer (KYC) onboarding, or a GDPR subject access request (SAR).

Spaces is for when you need an encrypted, controlled place where files and folders move both ways, between you and a defined group of people, for as long as the work lasts.

How it works

Verified people, controlled access, a full record of everything

Built for sensitive, ongoing work between a defined group of people.

Features

Controlled, audited and encrypted, by default

End-to-end encryption for files & folders

Everything in a Space is encrypted on each person’s device. See how the encryption works →.

Admin-verified user access

An admin confirms who each person is before they get anywhere near the files.

Full audit trail

Every upload, download, permission change and login, recorded.

Folder structure support

Upload a folder tree and it arrives with its structure intact.

Expiry and retention controls

Decide how long a Space and its contents stick around.

Granular permissions

Read-only, contribute or admin, set per person.

Own branding & custom domain

Branded Spaces for client work on the Enterprise tier.

Bulk upload and download

Move whole folders in and out in one go.

Browser-based

Nothing to install. Any device, any operating system.

Use cases

Built for two kinds of ongoing, sensitive work

Persistent Workspaces

One Space per matter, client or project

Legal: a Space per matter

A persistent encrypted Space for each matter, where files and folders pass between firm, client and counsel under controlled access. Branded on Business. For external exchange around a matter, not a replacement for your document management system.

Legal solutions →

Wealth: a Space per client

An ongoing room for statements, reports, suitability documents and onboarding evidence, all under admin control and audit.

Wealth solutions →

Education: a Space per research project

An ongoing encrypted Space for a research collaboration, where data, drafts and findings move between institutions, partners and funders under controlled access. Built for sensitive and pre-publication work.

Education solutions →

Compliance and M&A

Regulated exchange and disclosure

M&A and capital-markets due diligence

A virtual data room with admin-controlled access and a full audit trail. The UK-sovereign, mid-market alternative to enterprise data rooms like Intralinks and Datasite, which tend to charge £20k to £30k a deal. Best suited to deals under £100 million.

Virtual data rooms →

Legal disclosure rooms

An encrypted disclosure room for litigation, regulatory submissions and exchange between counsel, with every access logged.

Virtual data rooms →

Inter-organisation regulated sharing

Government to contractor, public body to delivery partner, wealth firm to regulator. Audited, sovereign and controlled.

Government solutions →

Need to send one file, not run a whole Space?

Secure file sharing sends a single file with end-to-end encryption, and no account for the recipient.

Pricing

Start with a free Space. Upgrade when you need more.

Every module is on every tier. For Spaces, what changes is how many Spaces you get, plus files and how long they last.

FAQ

Secure spaces, answered.

What are Spaces?
Spaces are secure, encrypted folders for ongoing collaboration. Multiple people can upload and download files to the same space, with full audit logging and access control.
How many Spaces can I have on the free tier, and what are the caps?
One Space with a 14-day expiry. Team raises the caps, Business gives you three Spaces, and Enterprise is unlimited.
Are uploaded folders preserved with their structure?
Yes. Upload a folder tree and it keeps its full hierarchy.
What does the audit trail capture?
Every upload and download from a space is fully audited.
Can I brand a Space for client work?
Yes. Own-branding and a custom domain on the Enterprise tier.
How does this differ from SharePoint or Dropbox shared folders?
Admin-invited users, a full audit trail, UK sovereignty, and true end-to-end encryption.
Is this suitable for M&A or legal disclosure?
Yes. See the data-room and disclosure use cases above, and the compliance page.
Is our data stored in the UK?
Yes. UK-hosted by default, not as a paid extra. The compliance page has the specifics.
What encryption does Hexiosec Transfer use?
Hexiosec Transfer provides true end-to-end encryption. Files are encrypted on the sender’s device before upload and remain encrypted until they are decrypted by the intended recipient. This is implemented using well-established cryptographic algorithms including AES-256-GCM for encryption, ECDH P-384 for key exchange, and PBKDF2 and HKDF for key derivation. Communications with the service are additionally protected using TLS 1.3.
