What this accessory does that alternatives don't.
Juice-jacking defence in hardware
The data lines are physically absent, so a hacked charging station or cable cannot negotiate a data connection with your device — not a software setting that can be bypassed.
Covers the sockets you actually meet
Public charging points, hire cars, and hotel desks are overwhelmingly USB-A. This is the direction our USB-C model does not fit.

Compliance framework mapping
Controls this product satisfies across 12 frameworks.
Hardware attack-surface reduction
Intel Management Engine disabled at the firmware level across every open-firmware machine we carry (NitroPad, NitroPC, PrivacyGuard, SecurityTitan); SecurityTitan models go further — camera and microphone physically removed, anti-tamper seals verified by Heads + Nitrokey attestation. Least functionality, enforced in hardware.
Compared to
Honest comparisons against the most likely alternatives.
vs. the USB-C data blocker
Same protection, opposite connector. Carry both if you travel — you cannot predict which socket you will be offered.
