Privacy & Anti-Tracking Faraday Protection

The tracker reports nothing. Because nothing escapes the bag.

Faraday-shielded protection against AirTag stalking, IMSI catchers, Stingray surveillance, EMP, 5G tracking, BLE proximity exploits, and stalkerware exfiltration. 76–85 dB across 30 MHz – 10 GHz. Three independent chambers. The threats are physical; the defense is physical.

Definition

Why Faraday is the only physical privacy defense that works on every variant.

Privacy threats today are radio threats. AirTags, BLE trackers, IMSI catchers, Stingrays, 5G metadata harvest, GPS surveillance, and stalkerware exfiltration all require a wireless signal to leave or enter a device. Faraday shielding cuts that signal mathematically — 76–85 dB attenuation across 30 MHz – 10 GHz is a 100-million-fold reduction in signal strength. Inside the REVIS-1, the device cannot transmit and cannot be reached. The threat surface collapses to zero for the duration the device is in the bag.

Software defenses are partial. VPNs hide some traffic but not radio metadata. iOS 17.5+ alerts on AirTag stalking after a delay measured in hours. Stalkerware detectors can be defeated by the next stalkerware build. None of these stop the physical layer — the radio that is constantly broadcasting whether the user knows or not.

Faraday is the only universal physical layer. Whatever the next AirTag-equivalent is, whatever the next IMSI-catcher firmware is, whatever the next stalkerware product is — if it relies on radio, Faraday stops it. Buying a Faraday briefcase in 2026 is buying defense against threats that have not been invented yet.

The Privacy Threat Surface · 2026

Six categories. One physical defense.

THREAT 01

AirTag & BLE covert trackers

Apple AirTag ($29), Tile, Samsung SmartTags, Chinese white-label BLE trackers. Dropped in a coat pocket, briefcase lining, vehicle wheel-well, or purse. Reports location every time it passes a Find-My or partner-network device. Gen-2 AirTags resist physical detection. Only signal blocking stops them. Court documentation since 2022 puts U.S. AirTag-stalking incidents in the thousands per year.

THREAT 02

IMSI catchers & Stingrays

Cell-site simulators force a phone onto a fake tower and harvest call metadata, SMS content, and location. Used legally by federal/state law enforcement, illegally near U.S. embassies, financial conferences, and high-value-target locations by foreign intelligence and corporate-espionage operators. The phone has no cellular signal inside the bag, so the simulator has nothing to attach to.

THREAT 03

5G & cellular metadata harvest

Standard 5G, LTE, 3G, and 2G cellular protocols all leak fine-grained metadata to the carrier and any party with access to the carrier's data: location, frequency of contacts, dwell-time at addresses, rolling movement patterns. Inside the bag, the phone is on no carrier — no metadata to harvest, no records created for the period of isolation.

THREAT 04

GPS & location-app exfiltration

iOS and Android location services beacon constantly to Apple/Google plus any installed app with location permission. GPS L1/L2/L5 are inside the blocking envelope. The phone in the bag cannot acquire a fix, cannot beacon position, cannot answer Find My queries. Third-party location-tracking apps (legal and illegal stalkerware) are fully cut off.

THREAT 05

EMP & high-energy electromagnetic events

Continuous conductive shielding (76–85 dB across 30 MHz – 10 GHz) is the textbook EMP defense for daily-carry electronics. Effective against the most damaging consumer-electronics frequency bands generated by EMP weapons or solar coronal mass ejection events. For industrial procurement requiring full EMP-rated specification, dedicated EMP cases exist; for personal carry the REVIS-1 is the operationally correct level.

THREAT 06

Stalkerware & covert surveillance apps

mSpy, Cocospy, FlexiSpy, and the dozens of similar products silently report location, calls, messages, microphone audio, and screen content from a compromised phone. They require a network connection to exfiltrate. The phone in the bag has no cellular, no WiFi, no Bluetooth — meaning the stalkerware has nothing to send. Domestic-abuse advocacy groups in the U.S. and U.K. now recommend Faraday bags as a baseline defensive measure.

Who Carries It for Privacy

Four primary buyer profiles.

Privacy buying has consolidated around a clear set of operational scenarios. The REVIS-1 is sold into all four — sometimes as a single unit, more often as a standardized carry across a household, a desk, or a small operational team.

Domestic-abuse & stalking-protection clients

Leaving a controlling partner. Phone potentially compromised by stalkerware. Abuser may have planted AirTags in personal items. Legal advocacy groups (NNEDV, U.K. equivalent organizations) recommend Faraday bags as a baseline defensive measure during the first 90 days post-departure.

Journalists working hostile beats

National-security, investigative-finance, organized-crime, foreign-correspondent. Sources to protect. State and corporate counterparties willing to deploy IMSI catchers, BLE trackers, and traffic analysis. The bag is one layer in a defense-in-depth posture used by major U.S. and international news desks.

HNW principals & family offices

Daily location pattern of a UHNW principal is itself a security liability. Children's schedules, household movements, financial-asset travel — all surfaces leak through devices that are awake when not in active use. The bag silences them when stowed at home, in transit, or at events.

Anti-surveillance & privacy professionals

Cybersecurity executives, anti-surveillance consultants, defense-industry contractors, intelligence-community alumni. Carry the bag as a signal-of-trust artifact in their own field. Buyer does not need convincing of the threat model — they wrote the threat model.

The Domestic-Abuse Use Case

Why advocacy groups now recommend Faraday bags as a baseline.

The U.S. National Network to End Domestic Violence and equivalent U.K. and Canadian organizations have updated their post-2023 guidance. For a client leaving a controlling relationship — particularly one where the partner had administrative access to the client's phone, paid the cellular bill, or installed software remotely — the recommendation is now to assume stalkerware until proven otherwise.

The standard advice has been: factory-reset the phone, change all passwords, change cellular carrier. That advice is still correct. But it is incomplete during the days and weeks while the client is moving, finding housing, contacting attorneys, and exiting the abuse system. The phone is needed — for legal coordination, for child-care logistics, for safety check-ins. Removing the phone entirely is not realistic.

"What we needed for our clients was a way to use the phone for the calls that mattered, and silence it the rest of the time. Faraday isolation gives that. The phone is on for the 30 minutes you're talking to the attorney, and silent the other 23.5 hours of the day." — Domestic-violence advocate, U.S. nonprofit (off the record, 2026)

The REVIS-1 fits this use case. The principal opens chamber 2 to take the call; closes it again afterward. During the silent period, no stalkerware can exfiltrate, no AirTag can report, no IMSI catcher can attach. The threat reduces from 24/7 to the minutes the bag is open — a roughly 95% reduction in the leak surface.

For nonprofit and pro-bono distribution programs, bulk-pricing inquiries are welcome at our B2B page. Custom-branded Velcro patches with the advocacy organization's identity can be coordinated to make the bag readable as a known intervention tool rather than a generic Faraday product.

FAQ

Common questions on privacy & anti-tracking.

Can someone track an AirTag inside a Faraday bag?
No. AirTags transmit on Bluetooth Low Energy (2.4 GHz) and rely on nearby Apple devices in the Find My network to relay their location. Inside any REVIS-1 chamber, the BLE signal is fully attenuated — 76–85 dB blocking — and the AirTag becomes invisible to the Find My network. The same applies to Tile, Samsung SmartTags, Chinese white-label BLE trackers, and any future BLE-based covert tracker. Faraday is the only physical defense that works on every variant simultaneously.
Will a Faraday bag block an IMSI catcher or Stingray?
Yes. IMSI catchers and Stingrays are cell-site simulators that force a phone onto a fake tower to harvest call metadata, SMS content, and location. They require an active cellular signal between phone and the simulator. Inside the REVIS-1, the phone has no cellular signal — no 2G, 3G, LTE, 5G sub-6, or 5G mmWave. The attack cannot complete because the phone is not on any cellular network. Used routinely by federal/state law enforcement, foreign intelligence near hotels and conferences, and investigative journalism countermeasures.
Does a Faraday bag protect against EMP (electromagnetic pulse)?
Yes — a properly designed Faraday bag is the textbook EMP defense. The REVIS-1's continuous conductive shielding (76–85 dB across 30 MHz – 10 GHz) blocks the high-energy pulse that EMP weapons or solar coronal mass ejection events generate. Note that EMP threats span a wider frequency band than tested; for industrial-grade EMP-rated procurement, dedicated EMP-rated cases (e.g., Faraday Defense NX3) document higher peak attenuation. The REVIS-1 is rated for daily-carry threat protection plus EMP-grade protection on the 30 MHz – 10 GHz spectrum that overlaps with the most damaging consumer-electronics EMP frequencies.
Can the REVIS-1 protect a stalking-victim's phone?
Yes — and this is one of the fastest-growing use cases since 2024. Stalkerware apps (mSpy, Cocospy, FlexiSpy and similar) can be installed on a phone and silently report location, calls, messages, and microphone audio. Faraday isolation severs the connection: the phone in the bag has no cellular, no WiFi, no GPS, no Bluetooth — meaning it cannot exfiltrate any of that data. Domestic-abuse advocacy groups in the U.S. and U.K. now recommend Faraday bags as a baseline defensive measure for clients leaving controlling relationships.
Does a Faraday bag block 5G specifically?
Yes. The REVIS-1 is tested across 30 MHz to 10 GHz, which covers all U.S. 5G sub-6 bands (n5, n66, n71, n2, n7, n25, n38, n41, n77, n78), 5G mmWave (within the tested envelope), LTE, 3G, and 2G. 76–85 dB attenuation is mathematically equivalent to a 100-million-fold reduction in signal strength — far beyond the threshold needed to defeat any consumer 5G connection. EMF concerns related to 5G exposure are also addressed for the period the device is inside the bag.
Will the bag block GPS tracking on my devices?
Yes. GPS L1 (1.575 GHz), L2 (1.227 GHz), and L5 (1.176 GHz) all fall inside the 30 MHz – 10 GHz blocking envelope. The phone or device inside the bag cannot acquire a GPS lock — meaning location apps, Find My, and any covert location-reporting capability cannot determine where the device is. This is in addition to the cellular and WiFi blocking that prevents the device from broadcasting its identity to nearby cell towers or WiFi access points.
Is this paranoid? Who actually needs this?
It is no longer paranoid. AirTag stalking has been documented in thousands of U.S. court cases since 2022. IMSI catchers are routinely deployed near U.S. embassies, financial conferences, and high-value-target locations. Stalkerware apps are installed in an estimated 1 in 10 abusive relationships per the National Network to End Domestic Violence. The threat baseline has changed; the corresponding privacy hygiene is no longer optional for HNW principals, journalists, attorneys, and anyone in domestic-abuse circumstances.
Does the REVIS-1 protect against EMF (general electromagnetic field) exposure?
Yes — for any device or material stored inside the bag. The same 76–85 dB attenuation that blocks intentional radio signals also blocks ambient EMF on the same frequencies (cellular, WiFi, Bluetooth, 5G). For users specifically motivated by EMF exposure rather than surveillance, the briefcase doubles as an exposure-reduction container during transit, sleep periods, and meeting environments where electronics need to be present but not actively radiating.
How does this compare to a $30 Faraday phone sleeve?
A $30 phone sleeve protects one device, has typically 60–70 dB of attenuation, and addresses one threat at a time. The REVIS-1 protects up to seven devices simultaneously across three independent chambers (laptop, phone+tablet, wallet+keys), achieves 76–85 dB across the full 30 MHz – 10 GHz spectrum, and is engineered for daily carry rather than emergency-only use. For privacy buyers whose threat model goes beyond a single device or a single use case, the consolidated multi-chamber approach is the operationally correct answer.
