Key Features
Key features
Hybrid physical and digital vault
HYBRID VAULT
Store seals, OTP tokens, bankbooks and confidential digital data in one security vault.
Dual encryption
AES-256 + RSA-2048
AES-256 and RSA-2048 encryption protect data if the device is lost or stolen.
PUF authentication
PUF
Authentication based on a unique semiconductor fingerprint prevents cloning.
Physical port control
SECURE PORT
USB-C ports and network drives are enabled only after PUF authentication.
Audio Recording & Storage
AUDIO STORAGE
Record and save audio.
Core Capabilities
Four core capabilities
Authentication and access management
- PUF USB hardware authentication controls server startup
- Register devices using administrator-issued QR codes and SSID/RSSI proximity checks
- Approve new devices with the six-digit code displayed on the vault
- Issue mTLS certificates and block unauthorised devices
- Request biometric authentication on the registered phone for desktop access
Local AI — offline document intelligence
- Local RAG and LLM use stored documents to answer questions and generate summaries
- Private-network local AI with an NPU rated at 6 TOPS
- Processing stays on the private network without external data transfers
- Document-based questions and answers using a Local Notebook LM approach
E2EE encrypted vault
- Encrypt passwords, contacts and other sensitive data on the client device
- End-to-end encryption prevents server administrators from viewing contents
- Dual encryption using AES-256 and RSA-2048
Integrity auditing and monitoring
- Record connection times and read, write and delete events in an immutable time-series database
- Real-time alerts for unusual access; automatic key erasure if compromised
- Monitor temperature, disks, memory and uptime in real time
- Synchronise files between devices to support business continuity

PUF · 3-Tier Access
PUF and three security tiers
Combine PUF, two-factor authentication and biometrics according to data sensitivity
Step 1 · Server startup
PUF
Hardware authentication (PUF USB)
Control startup through unclonable hardware authentication
- The vault cannot start without the key
- Removing the key locks the entire vault
- Automatic security key erasure if stolen or dismantled
Step 2 · Document access
Three security tiers
More sensitive documents require stronger authentication.
| Tier | Authentication | Document scope |
|---|---|---|
| CGeneral | ID and passwordEveryday business documents | Everyday business documents |
| DProtected | + Two-factor authenticationContracts, HR and finance | Contracts, HR and finance |
| EConfidential | + BiometricsCritical confidential data and intellectual property | Critical confidential data and intellectual property |
E Confidential Documents are displayed only after mobile biometric authentication (face or fingerprint) succeeds.
Every time you start the vault — Local AI without the internet
The vault’s startup sequence completes without external connections.
- KEY
1. Connect the hardware key
Insert the PUF USB key
Insert the registered PUF USB hardware key into the vault.
The vault cannot start without the key.
- BOOT
2. Authenticated startup
Security key authentication
Check the authentication result on the vault’s screen.
The vault starts only with an authenticated key. Removing the key locks the entire vault.
- AUTH
3. Security tier authentication
Verify C, D and E access rights
Three security tiers: C General (ID and password), D Protected (additional two-factor authentication), and E Confidential (smartphone biometrics).
More sensitive documents require stronger authentication.
- ACCESS
4. Access your assigned tier
View authorised C, D and E content
Access authorised documents and search or summarise them offline. Store physical items in the built-in A4 document drawer.
Local AI starts at the same time.
