Healthcare is the most breached sector
Medical practices hold some of the most sensitive personal data in existence. Centralised storage and legacy tools make healthcare disproportionately attractive to attackers.
Patient trust, mathematically earned.
Shield Desk gives medical professionals a secure operating environment for every patient interaction, where no data is stored, no communication can be surveilled, and privacy is guaranteed by architecture, not policy.
The problem
The risks these teams face daily
Healthcare organisations handle the most sensitive personal data in existence, yet most still rely on communication infrastructure that was never designed for genuine medical privacy.
Privacy principles are non-negotiable
Data minimisation, purpose limitation, and patient rights are foundational expectations. Platforms that store and process patient data centrally create inherent exposure.
Phishing and social engineering
Medical staff are frequently targeted by phishing impersonating insurers, labs, or colleagues. Centralised identity and email workflows create exploitable attack surfaces.
Fragmented tools across the practice
Most practices operate across email, SMS, video, and file storage, none designed for sensitive medical communication. The gaps between tools are where breaches occur.
Patient data persists without control
Once shared via conventional tools, there is no reliable way to retract, expire, or verify confinement. Data lingers in systems well beyond its intended use.
The solution
A secure operating layer, built for the work
Shield Desk is not a messaging app with a privacy badge. It is a purpose-built secure work environment built on distributed blind computation, a cryptographic model in which patient data is never centralised, never stored in a recoverable form, and never accessible to anyone outside the explicitly authorised parties.
- No patient data persisted on centralised servers
- No backdoors, not even for the platform itself
- Quantum-resistant cryptographic architecture
- Closed network of verified organisations and employees only
How blind computation works
Data never leaves your device unencrypted
All patient content is encrypted locally before transmission. Plaintext never touches Shield Desk infrastructure.
Processing without exposure
Computations such as search, indexing, and AI summaries are performed on encrypted data. Results are returned without the platform ever seeing the content.
No central point of failure
There is no single server holding your patient content. Even in the event of a platform-level incident, there is nothing to expose.
Mathematically verifiable guarantees
Confidentiality is enforced by cryptographic proof, not contractual promises or access policies.
Key features
Built for these environments
Secure patient communication
Text, voice, and video consultations conducted within a mathematically encrypted environment. No content is processed or stored on external servers.
Time-limited secure file sharing
Request and receive records, lab results, or imaging via permission-controlled, expiring links. Access is logged with a cryptographic audit trail and revocable at any time.
Decentralised data protection
Patient data is never centralised. Distributed blind computation ensures that even in a platform-level incident, there is no recoverable patient information to expose.
AI-assisted clinical workflows
Privacy-first AI agents summarise consultations, track follow-ups, and flag anomalies, all without the underlying patient data leaving the encrypted environment.
External collaboration with labs & specialists
Collaborate securely with laboratories, imaging centres, insurers, and specialist referrals inside permission-controlled shared spaces, without exposing internal systems.
Mobile, desktop and web
Full feature parity across all devices. Physicians can review summaries and communicate securely from anywhere, with the same encryption guarantees everywhere.

- No persistent storage of their personal data
Use case scenarios
How these teams use Shield Desk
Doctor reviews lab results securely
A physician receives lab results while off-site and accesses them on mobile, fully encrypted with no cached data. A summary with flagged values is ready for immediate review.
Nurse requests documents from patient
A nurse needs insurance and referral documents before a procedure and sends a secure, time-limited upload link. The patient uploads; the link expires automatically. No email, no third-party cloud.
Patient attends a secure video consultation
A patient joins a telemedicine consultation via a secure Chamber. The call is end-to-end encrypted, transcribed internally, and summarised for the physician's records, never on an external platform.
Admin coordinates billing securely
An administrator shares billing records with an external accountant via a permission-controlled, time-limited shared space. Access is logged cryptographically and revoked automatically.
AI assistance
Intelligence that protects, not exposes
Clinical intelligence
Leia
Leia summarises patient consultations, extracts clinical action points, and drafts follow-up notes, all within your encrypted environment and never exposing patient data externally.
Workflow & follow-up tracker
Tegan
Tegan monitors pending follow-ups, outstanding lab requests, and unanswered messages, surfacing what needs attention without storing or exposing medical content.
Security & risk watchdog
Sarg
Sarg monitors file sharing, vault access, and user behaviour. If a record is shared outside authorised parameters or an unusual pattern appears, Sarg flags it immediately.
Integrations
Works with your existing workflow
Shield Desk is a security layer, not a forced replacement. It adds encryption and access controls to the tools your team already uses.
Google Drive
Securely access and share medical files without leaving the encrypted environment.
Google Calendar
Sync patient appointments, consultations, and staff schedules with full context.
Gmail
Bridge existing email workflows into a secure communication layer for the practice.
Slack
Migrate sensitive internal coordination from Slack into encrypted channels.
Zoom
Replace unencrypted video calls with Shield Desk's secure Chamber sessions.
Google Docs
Collaborate on clinical documentation and referral letters within a protected workspace.
Why it matters
Traditional tools vs Shield Desk
| Feature | Traditional tools | Shield Desk |
|---|---|---|
| Data storage | Centralised servers, persistent exposure risk | No data stored, mathematically eliminated |
| Encryption | Transit-only TLS, exposed at rest | End-to-end plus blind computation, always encrypted |
| Video consultations | Third-party platforms with their own data policies | Encrypted Chambers, no external data processing |
| File sharing | Email or cloud links, no expiry or control | Time-limited, permission-controlled, revocable |
| Access control | Application-layer policies, bypassable | Cryptographic enforcement, architecture-level |
| Breach risk | High, centralised data is a target | Structural, nothing centralised to breach |
Security & compliance
Designed for strict confidentiality
Shield Desk is built around principles aligned with modern data protection expectations, including data minimisation, purpose limitation, and patient rights. It does not claim certifications beyond what its architecture directly enforces.
Mathematically secure
Privacy is enforced by cryptographic proof, not policy. The architecture makes unauthorised access structurally impossible under known mathematical methods.
No data storage
No patient information is persisted in a recoverable form. There is nothing to breach, subpoena, or expose.
Decentralised, blind computation
Data is never centralised. Computation happens on encrypted data; the platform never sees the content it processes.
Quantum-resistant architecture
Cryptographic standards are selected to remain secure against quantum computational approaches, protecting patient data long term.
