A small community of enthusiasts reverse-engineers the ST-5150 firmware for extended functionality:
Risks of custom firmware:

Only use builds from GitHub repositories with verified SHA256 checksums. Never run a custom bootloader. satlink st-5150 firmware
VSAT modems are rarely managed via local interfaces; they are designed for "zero-touch" deployment in remote locations. Risks of custom firmware:
Common firmware versions seen in the wild: If you choose to explore: Only use builds
Upon power cycling, the ST-5150 executes a sequential boot process:
Historically, satellite modems, including earlier iterations of Satlink firmware, relied on "security through obscurity." Authentication between the modem and the hub is often based on a MAC address or a hardcoded serial number, rather than mutual cryptographic authentication (e.g., TLS with client certificates). While the DVB-S2 stream itself may be encrypted at the application layer (e.g., via a VPN), the management plane between the ST-5150 and the hub is frequently transmitted in cleartext.
