Faraday & signal blocking · Mission Darkness
When the device must go silent, hope is not a shield.
Faraday bags physically cut every radio — cellular and 5G, WiFi, Bluetooth, GPS, RFID, NFC — so a phone can't be tracked, remotely wiped, or made to phone home. We curate Mission Darkness by MOS Equipment: US-assembled, tested to MIL-STD 188-125 and IEEE 299-2006, with lab reports to prove it. Sold through Amazon — same price as going there yourself.
Why this brand — the knockoff filter
How to spot a fake: Require published MIL-STD 188-125 or IEEE 299-2006 test data, a stated dB attenuation figure, and US assembly. "Military grade" claims with no test report, single-layer fabric, or stitched (leak-prone) seams fail the filter.
The lineup
Phone — see the screen Window Faraday Bag for Phones
Executive travel & digital forensics — confirm signal cutoff through the RF-FilterVu window
The transparent shielded window is the trick: you can watch the phone lose signal when the bag seals, and check the screen without breaking shielding. The forensics-standard way to transport a phone that must not phone home.
Keyfobs — anti relay attack Faraday Bag for Keyfobs (2-Pack)
Anyone with keyless-entry vehicles — relay/amplification attacks copy your fob signal from inside your house
Keyless car theft works by amplifying the fob signal sitting by your front door. Two pouches, one per driver, and the relay attack has nothing to amplify. The cheapest physical-security win in the collection.
Phone — full blackout Non-Window Faraday Bag for Phones
Maximum shielding for travel, protests, sensitive meetings — or devices going into evidence or a safe
The solid version of the phone bag — full TitanRF coverage, no window. Pairs with a fire-rated safe for phones and drives in storage: the safe stops fire and theft, the bag stops tracking and remote wipe.

Where this fits your program
Compliance mapping
Emanations and signal isolation map to NIST PE-19 (information leakage), MP-5 (media transport — the forensics chain-of-custody use), and SC-42 (sensor capability) — cross-framework detail in the compliance library.
Pairs with a safe
Phones and drives going into storage want both layers: the fire-rated safe stops fire and theft, the bag inside it stops tracking and remote wipe. Evidence handling 101, applied at home.
The travel kit
Keyfob pouches at home, phone bag in the carry-on, our own Nitrokey Faraday sleeve ($55) for everyday carry, and a data blocker for the airport — the whole kit costs less than one hour of incident response.
