UK Sovereign, Secure File Transfer with End-to-End Encryption

Your files are encrypted before they leave your device. We never see the keys—only the recipient can read them. No one else. Not even us

Hexiosec Transfer is built, maintained and hosted in the UK, for a sovereign capability.

For Enterprise

Our fully white-labelled version extends the trust your customers have in your brand to the way they receive important data from you.

We can add your logo, domain, and colour scheme to your own version of Hexiosec Transfer, to provide a seamless experience.

Show your customers that you are serious about data protection.

For Individuals

Ensure privacy and security for your personal files too. If you need to send sensitive data such as passport details or bank statements, you don't have to trust email attachments that sit in other people's inboxes.

Trebuchet is our branded version of Hexiosec Transfer for individuals. It's the same secure service, and you can use it for free by signing up today.

How it works

When you send files, they are encrypted in your browser before being uploaded to our servers. With Hexiosec Transfer your files never leave your computer unencrypted, and are not copied or stored unencrypted at any point.

Once uploaded you can share the files with just a link, making it simple for the recipient to get your files.

Crucially, no-one, including us, can download and decrypt the files without this second part of the link. This decryption key is never sent to us.

Only if someone has the full link can they download and decrypt the file, and only before the link expires. You can also add a password, or restrict downloads to only verified recipients for additional protection.
