Linkbox + Security & Privacy Information

  • Oppdatert

(meets the user‑information requirements of EN 18031‑1:2024, Annex B - Cyber Security)

1. Authentication (B .2 .2 .1)

Linkbox + proves its identity to the Abra Cloud and Abra App with a factory‑installed X.509 device certificate that is unique for every unit.

  • There is no password or PIN login on the gateway itself.

  • If the certificate ever needs to be replaced (e.g. after repair) the process is performed automatically by the Abra Cloud and logged in the App.

2. Software & firmware updates (B .2 .2 .2)

Your gateway keeps itself up to date:

Channel What happens Your action
LTE / Wi‑Fi / Ethernet The device checks once per day for signed firmware released by Abra. None – downloads and installs are automatic.
During install The gateway verifies the cryptographic signature before activating new firmware. The device reboots once; internet data flow resumes automatically.
After install A push notification appears in the Abra App: “Security update <version> successfully installed.” Review the release notes if you wish.

If an update fails its integrity check the Linkbox + rolls back to the previous firmware without user intervention.

3. Personal‑data processing (B .2 .2 .3)

The gateway itself stores only two pieces of personal data:

  1. Wi‑Fi network name (SSID) and passphrase – kept locally in encrypted flash so the device can reconnect after power loss.

These data never leave the gateway and are erased instantly when you perform a factory reset.

For everything else (sensor readings routed through the Abra Cloud, account information, retention periods, your rights, etc.) please see our full Privacy Policy: https://support.abralife.com/hc/en-us/articles/Privacy‑Policy.

4. Notification of security‑relevant changes (B .2 .2 .4)

Whenever a change could affect the protection or privacy of your data the Abra App will notify you within seconds. Examples include:

  • A new firmware version has been installed.

  • The device certificate has been rotated.

  • Encryption features have been enabled or disabled.

  • A secure‑erase (factory reset) has been performed.

Each notification contains:

  • What changed (e.g. “Firmware 1.6.2 installed”)

  • Impact on your privacy (only if any)

The same information is logged in Settings ▸ Release Notes in the Abralife app.

5. Reporting security vulnerabilities (B .2 .2 .5)

We operate a coordinated vulnerability disclosure programme.

  • Email: security@felltech.no

  • Response target: acknowledgement within 5 business days, initial remediation plan in 15 business days.
