Question about Invoxia GPS Tracker Mini

The device communicates via Bluetooth, LoRa and or Sigfox, did I understand that correctly? My question now is this, Sigfox has some security gaps which are also mentioned in an online article. https://eprint.iacr.org/2020/1575.pdf I am now wondering, how does it look with regard to the tracker, is it additionally protected? is the data additionally encrypted by Invoxia? unfortunately there is very little information on their website....
