The Kontakt.io Secure Profile packet is one of the connectable packets, along with the Kontakt.io Telemetry and Kontakt.io Location packets, (ADV_IND), broadcasted by the broadcasting device, allowing iBeacon and Eddystone packets to remain non-connectable (ADV). For more details please refer to Packet broadcasting rules.
There are two variants of the Kontakt.io Secure Profile. And which one is broadcasted depends on if Secure Shuffling is enabled or not enabled.
Below are the packet structures for both variants.
