In the News: How to Protect Your Phone From Surveillance

As digital surveillance at protests makes headlines, Mission Darkness faraday bags are being recognized as a must-have for protecting your phone’s location, data, and privacy.

Read this timely article to learn how faraday bags block tracking signals and keep your personal information secure: How to Use a Faraday Bag to Protect Your Location and Privacy at a Protest.

KEEP CELL PHONES AND SMALL DEVICES SHIELDED

The Mission Darkness™ Non-window Faraday Bag for Phones completely blocks all wireless signals and keeps small electronic devices shielded to prevent hacking, tracking, spying, and chain of custody corruption. When a cell phone is properly enclosed in the bag, no apps or malicious code can be remotely triggered or wiped, no communication can penetrate, and no one can access the microphone, camera, GPS location, or data. Primary uses are for law enforcement and military forensic evidence collection, defense against data theft, personal security, EMP protection, EMF radiation reduction, and to enhance digital privacy.

In addition to law enforcement and military forensic evidence collection, defense against data theft, personal security, EMP protection, EMF radiation reduction, and enhancing digital privacy, the Non-window Faraday Bag offers a critical layer of protection for protesters, activists, journalists, and anyone attending high-risk events where digital surveillance is a concern. Enclosing your phone in the bag prevents real-time location tracking, cell tower pings, rogue IMSI catcher interception, and metadata harvesting—common tactics used by authorities and third parties to monitor and identify participants in public gatherings. The bag helps ensure anonymity, making it a vital tool for safeguarding personal freedom and privacy during protests and demonstrations.

The bag is built with a durable and water-resistant ballistic nylon outer material to ensure that devices and faraday fabric stay dry and protected. The interior includes two layers of high-shielding TitanRF™ Faraday Fabric on all sides with dual paired seam construction. The bag will block all wireless signals such as WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, NFC, and radio signals from low MHz to 40GHz. Additional product features include a double roll with Velcro closure, unique serial number, and transparent branding pocket.

The bag is typically used to shield cell phones, passports, GPS units, transponders, two-way radios, keyfobs, smart watches, and similar size electronics.

Protect your anonymity with our top-rated phone faraday bags—designed specifically for protesters, activists, and anyone serious about digital privacy. As WIRED recently detailed in “How to Protest Safely in the Age of Surveillance,” smartphones can broadcast your presence at rallies, and law enforcement often uses IMSI catchers, cell‑tower data, and facial recognition to track participants.

Our Stay Invisible Collection features faraday bags that block cellular, GPS, Wi‑Fi, Bluetooth, and NFC signals—meaning your phone stays truly off the grid even if it’s powered on. Faraday bags offer a reliable alternative to airplane mode, reducing the risk you’ll be geotagged by rogue towers or passive surveillance devices.

How faraday bags helps you stay safe:

  • Complete signal blackout — blocks cell signals, GPS tracking, WiFi, Bluetooth, RFID, and NFC

  • Burner phone compatible — prevent real-time location tracking and metadata leaks

  • Rugged, portable design — these durable designs built for frequent use and fast deployment in high-risk situations

Stay invisible to surveillance technology and maintain full control over your phone’s data, location, and wireless signals — even when powered on.

Real Good, Every once in a while my iPhone freezes, 30 seconds in this bag and my iPhone is ok. It may be some type of outside interference that the bag disrupts,
