Security

Built for hospital IT

CoaguCare was designed with hospital IT requirements and patient data protection in mind from day one.

  • ✓
    Fully offline after setupNo data ever leaves your hospital network. No cloud. No third-party processors.
  • ✓
    bcrypt password hashing (cost 12)Industry-standard adaptive hashing at cost factor 12. Passwords are never stored in plain text.
  • ✓
    Randomised session secret per installationA unique 64-byte cryptographic secret is auto-generated on first boot and never hardcoded.
  • ✓
    Login rate limitingFive consecutive failed attempts locks the account for 15 minutes, preventing brute-force attacks.
  • ✓
    Server-side session managementSessions expire after 8 hours. httpOnly cookies only — no sensitive data in URLs or browser storage.
  • ✓
    Append-only audit logEvery action recorded with user, timestamp, and record affected. Cannot be deleted or modified.
  • ✓
    Crash-safe databaseSQLite WAL mode prevents data corruption even during unexpected power loss.
  • ✓
    HTTPS-readyBuilt-in TLS support. Provide a hospital CA certificate and the app switches to HTTPS automatically.
Data stays on your hardwareSingle SQLite file on your designated server PC — full IT control
Role-based access controlSenior Pharmacist · Pharmacist · Pharmacy Technician — enforced server-side
Full IT documentation includedSecurity overview and setup guide ready for IT and DPO review
Open source stackNode.js · Express · React · SQLite — fully auditable by your IT team

After sign-up, you'll receive a download link and a licence key by email — Windows .exe or Mac .dmg. No prerequisites required.

2

Double-click to install

Run the installer like any other app. CoaguCare installs in under a minute with no technical steps required.

3

Log in & explore

The app opens with demo patients pre-loaded so you can explore every feature straight away before going live.

4
