A direct, post-quantum encrypted channel between two devices — or between you and a colleague. Files of any size and any kind. Nothing uploaded, nothing stored, nothing passing through anyone you have to trust.
Data captured today can be stored and decrypted years later, once quantum computers mature. Anything that must stay secret for years needs protection that holds up against machines that do not exist yet.
An adversary records encrypted traffic now and simply keeps it.
A mature quantum computer breaks the old encryption and reads what was saved.
Post-quantum encryption keeps the same data protected against those future machines.
PQVault is a platform of eight modules that share the same post-quantum foundation. Every module is available — a selection is shown here.
One click, one bridge — send anything between devices.
Encrypted messaging, calls and files for your team.
Zero-trust data rooms with workflows, resolutions and e-signatures.
Publish an encrypted item behind a link.
Encrypt files locally, share them and revoke access.
Post-quantum transfer in your own product.
Policy, audit and monitoring across the platform.
Local drives, stored encrypted in SharePoint, OneDrive or Dropbox.
No account on the other device, no cable, no app store detour. Connect with one click, drop your files, watch them arrive on the other side.
One click opens a fresh bridge to the other device. It closes on its own.
Files or a whole folder, any type, any size. Progress and speed show live.
The other device receives each item directly. Nothing waits on a server in between.
Take either on its own, or both together. Both rest on the same post-quantum foundation and the same principle: your data never sits on our infrastructure.
One click on each device and a direct channel opens between them. Phone to laptop, laptop to tablet, your device to someone else’s.
Encrypted messaging, calls and file exchange between colleagues, with a record of what happened that belongs to you alone.
No hidden hop, no silent copy. Here is the whole path your data takes in each product.
One click opens one span between your devices. The data crosses it and the span closes behind you.
Messages, voice and video run straight between the people in the room. Our servers help them find each other and then stay out of it.
Share confidential documents with buyers, partners and auditors, and keep every decision inside the room. Every request is verified, every document post-quantum encrypted, every step on record.
Watermark, expiry date, password and download lock. Set per link, revocable at any time.
Members, guests and auditors with rights per room and folder. Access ends when the role ends.
Multi-stage sign-off with deadlines, and a record of who approved what and when.
Circular resolutions with quorum, voting and minutes. Decided and archived in one place.
Sign inside the room and see each signer's status, without sending a single attachment.
Question rounds with assignment, deadlines and released answers, instead of email threads.
Exchange and version Industry 4.0 digital twins, sealed between supplier and customer.
Automatic validation against EN 16931 (XRechnung, ZUGFeRD) before an invoice moves on.
Define the path a document takes once, and the room runs it. Checks, approvals, resolutions and signatures follow in order; a rejection sends the document back on its own.
This is the path of a supplier invoice through a project room. Each step is a rule you set once.
Each link carries its own rules. The recipient sees a view watermarked with their name, until the date you set or until you revoke it.
Connect your ERP, DMS or machine data. Documents are encrypted before they leave your system and arrive in the room sealed.
Wherever several parties need the same documents but must not see everything.
Due diligence with separated bidders, Q&A rounds and signing at closing.
Plans, change requests and acceptance with external partners, on deadline.
Property files, valuers and banks with time-limited access, owner resolutions in circulation.
Drawings, material certificates, AAS and e-invoices along the supply chain.
Studies, cooperation contracts and findings on a need-to-know basis, every access logged.
Credit files, syndicates and audits with documents that must stay confidential for years.
Client files, contract drafts and signatures without email attachments.
Board packs, circular resolutions and minutes for supervisory and advisory boards.
Two products for the files you already have. One keeps your cloud storage blind, the other lets you take back what you sent.
Create local drives that are stored encrypted in SharePoint, OneDrive or Dropbox automatically. You work in your file manager as usual; the provider only ever holds ciphertext.
Encrypt files on your computer and share them with rules attached. Revoke access, and even a copy sent long ago can no longer be decrypted.
Your cloud provider sees blocks it cannot read. A recipient you revoked sees a file that no longer opens.
Files are encrypted on your device. What lands in the cloud has neither a readable name nor readable content.
Opening a file needs a key that is checked against your rules. Revoke a recipient and the key is no longer issued, wherever the copy is.
If it would be a problem in a leak, it should not travel through a messenger or sit in someone else’s cloud.
Move a full backup between machines at local speed, without staging it in a cloud you would then have to purge.
Hand over a vault export, a recovery kit or an access file without it ever landing in a chat history.
Whole shoots and long recordings straight from camera to laptop — no compression, no upload wait, no quota.
Designs, source, formulas and research that must not exist as a second copy anywhere outside your control.
Signed originals and due-diligence packs delivered directly, with the other side confirmed before they move.
Scans and patient files between devices without creating a duplicate that must then be tracked and deleted.
Multi-gigabyte models, drone captures and site data handed over on location, without waiting on a connection.
Sometimes it is simply the fastest way to move forty gigabytes from one device to another without a cable.
The channel exists only while you need it, then closes and leaves nothing behind on either side.
Open a bridge with one click on each device, or invite a colleague. Any modern browser is enough.
Both sides see the same confirmation before anything moves, so you always know who is on the other end.
Move a file of any size, or message and call. Close the session and the channel is gone with it.
Encrypted traffic captured today can be stored and broken later. Anything meant to stay confidential for years needs post-quantum protection now.
Built on post-quantum cryptography, so material stays protected against the computing power that is coming, not just today’s.
Data travels straight between the two ends over your own connection. No upload step, no throttling, no third hop.
No copy on our servers, ever. There is nothing to be requested, breached or forgotten about later.
Works in the browser both people already have. Nothing to install, no setup menus, no platform lock-in.
Every channel is confirmed by both sides before data moves, so a transfer is never handed to the wrong person.
Because content never crosses our infrastructure, it cannot leave your region by accident. On-premise is available.
Most confidential files still travel by messenger or cloud link. Both leave a copy somewhere you do not control.
| PQVault | Messenger | Cloud link | Bluetooth / AirDrop | |
|---|---|---|---|---|
| Copy left on a third-party server | Never | Yes | Yes | No |
| Post-quantum protected | Yes | No | No | No |
| App required on both sides | Browser only | Yes | Account needed | Same platform |
| You know who received it | Confirmed | Rarely | Anyone with the link | Device name only |
| Practical size limit | Your disk | ~100 MB | Plan quota | Slow above 1 GB |
| Runs inside your own perimeter | Yes, on-premise | No | No | Local only |
| Nothing waits on a server between you | Live session only | Queued on server | Held until fetched | Live only |
By design, the transfer runs only while both sides are connected. Close the window and the channel is gone — nothing is queued, cached or left waiting anywhere.
Create a free account, then choose a plan whenever you are ready. No card to start, nothing to install, and your data never leaves your devices.
