Devices With Expired Certificates Detection

Definition​

This feature checks device integrity by identifying devices with expired certificates. If such a device is detected, the application restricts or prevents execution to ensure a secure runtime environment.

Security Implications​

Devices with expired certificates cannot be fully trusted, as they may fail critical integrity checks. Such environments are vulnerable to tampering, rooting, or bypassing security controls. Allowing apps to run on these devices increases the risk of data breaches, unauthorized access, and runtime attacks.

How Certificate Expiry Happens:​

Certificate expiration on a device can occur due to several reasons:

  • The device is not connected to the internet for a long time, preventing certificate validation and updates.
  • Security keys or certificates are not rotated or refreshed as required due to unsupported versions.
  • The device is running outdated software or firmware.
  • System time/date is incorrect, affecting certificate validity checks.
  • Using an older device that doesn’t support remote key provisioning.
  • Device running on older Android version.

Recommendations:​

If your device is flagged due to an expired certificate, you can take the following steps to resolve the issue:

  • Update Device Software: Install the latest OS updates, as they often include updated certificates and security patches.
  • Check Date & Time Settings: Make sure your device’s date and time are set correctly (preferably in automatic mode).
  • Restart the Device: A simple restart can help refresh system services and certificate validation processes.
  • Avoid Modified Devices: If your device is rooted, jailbroken, or running unofficial firmware, restore it to a secure, official version.

If the issue persists, users should contact their device manufacturer or support team to ensure the device meets security requirements.
