How Faraday Bags Work: The Physics of RF Shielding

Faraday bags enclose a device in a conductive mesh that intercepts incoming electromagnetic waves, induces opposing surface currents, and dissipates the energy as heat. Cellular, GPS, WiFi, and Bluetooth never reach the device inside.

Faraday Bag Attenuation Ratings: What dB Numbers Actually Prove

A faraday bag's value lives in its attenuation rating. Look for tested performance of 60–100 dB across 10 MHz to 40 GHz, verified against MIL-STD-188-125 or IEEE 299. Anything else is marketing.

Range Rover Keyless Theft 2026 — Why Yours Is the Target

Range Rover is the most-stolen luxury vehicle in the United States. Insurance premiums up 60% in three years. The relay attack takes 60 seconds.

Hotel WiFi Attack Protection — How Executives Get Compromised on Business Travel

DarkHotel APT campaigns. Captive-portal MITM. Evil-twin SSIDs. The seven-step protocol corporate-security teams actually use.

Read Briefing

IMSI Catcher & Stingray Protection — The Faraday Defense Journalists Use

Cell-site simulators near conferences, protests, federal buildings. Your phone hands over its IMSI and gets logged. Apple's protections aren't enough.

Read Briefing

AirTag Faraday Bag — How to Block a Tracker You Found on Yourself

Someone slipped an AirTag into your bag, your child's coat, your car wheel-well. Apple's notifications come hours late. The Faraday isolation that silences it.

Best Faraday Bag for AirTag in 2026 — The Spec That Actually Silences It

Most "AirTag-blocking" pouches block weak cellular and leak the 2.4 GHz BLE band the AirTag actually uses. The five-test verification, and the spec floor that matters.

Read Briefing

Tesla Key Card & Phone Key — The Faraday Protocol Owners Are Missing

Tesla replaced the key fob with an NFC card and a Bluetooth phone key. Both are still relay-attackable. The four-step protocol Tesla owners use.

Read Briefing

RFID vs. Faraday — The Difference That Costs You Your Car

Your $40 RFID wallet blocks contactless skimming at 13.56 MHz. Your key fob broadcasts at 315 / 433 MHz. The relay attack walks through that wallet like it isn't there.

Concealed-Carry Briefcase 2026 — The EP-Grade Carrier Hip-Holster Can't Replace

Hip-holster prints under a suit. Sling packs read tactical. The boardroom-grade concealed-carry briefcase EP details and off-duty officers actually carry.

Read Briefing

Do Faraday Bags Really Work? Yes — When They're Built Right

The physics is settled. Quality bags hit 76–85 dB across 30 MHz – 10 GHz. Junk bags hit 30 dB at narrow cellular frequencies and call it "EMP protection."

Read Briefing

How to Test a Faraday Bag in 5 Minutes — The Protocol Used by Pros

Five tests anyone can run at home in five minutes — cellular, WiFi, Bluetooth, GPS, FM. The lab method (IEEE 299) for the spec sheet that matters.

Read Briefing

Does a Faraday Bag Block 5G? Yes — When Built for the Right Bands

5G isn't one frequency — it's three bands from 600 MHz to 39 GHz. Most "5G blocking" pouches cover the low band and leak the mid and mmWave entirely.

Read Briefing

EMP Protection Bag 2026 — What Actually Works (and What's Marketing Fluff)

Carrington-class solar storms. Tactical EMP devices. Most "EMP bags" on Amazon block your iPhone signal and nothing else. The MIL-STD-188-125 frame.

Read Briefing
Block Every Signal

The briefcase the briefings are written about.

Three independently shielded chambers. 76–85 dB attenuation across 30 MHz – 10 GHz. Designed for the principal who reads the threat brief once, then never thinks about the threat again.
