Definition

What is a forensic Faraday bag?

A forensic Faraday bag is a signal-blocking container used in digital forensics to preserve seized electronic devices in their on-scene state. The moment a phone or laptop is placed inside, all wireless connections (cellular, WiFi, Bluetooth, GPS) are severed — preventing remote wipe, password reset, location signaling, and any over-the-air data modification. Federal and state law enforcement, defense contractors, and corporate-security incident-response teams use Faraday bags as standard digital-forensics equipment.

The procurement requirement is narrow but consistent. The bag must fully attenuate every consumer wireless protocol (cellular 2G–5G, WiFi 2.4/5/6 GHz, Bluetooth, GPS L1/L2/L5, NFC, RFID), be documentable in chain-of-custody paperwork (test-report on letterhead, identifiable manufacturing origin, agency-branded patch system), and scale across multi-device intakes without requiring a separate bag per device.

The REVIS-1 satisfies all three. Three independent chambers handle a typical multi-device intake (suspect's phone, secondary phone, laptop, tablet, USB drives, wallet, keys) in one bag. Test-report on letterhead. Made in the United States. Custom-branded Velcro patch with agency identifier (10+ unit orders, no setup or tooling fee). Standard 4–6 week lead time; expedited 2-week production available for active-investigation outfitting.

On-Scene to Lab

The four-step forensic workflow.

STEP 01

On-scene seizure

Device is removed from suspect or recovered from the location. Case officer places it directly into the appropriate REVIS-1 chamber (laptop / tablet+phone / smaller items). Chamber sealed with Velcro closure. No power-down required — Faraday isolation is sufficient to prevent network access.

STEP 02

Custody documentation

Bag is tagged with case-evidence marker. For agencies using custom-branded REVIS-1 units (10+ unit procurement), the agency identifier patch on the bag matches the case-management system. Date, time, seizing officer, and location logged per agency standard operating procedure.

STEP 03

Transport & storage

Bag is transported to the forensics lab in the sealed state. Storage in evidence locker maintains Faraday isolation throughout — the device is not on any network for the entire transport-and-storage period. Battery may drain naturally; chain of custody is preserved against remote wipe and remote access.

STEP 04

Lab examination

Forensic examiner opens the chamber under controlled conditions in a Faraday-isolated examination room. Forensic image is acquired before any network reconnection. Original device's pre-seizure state is preserved in the image; the device may then be examined further or returned to isolated storage as case requirements dictate.

FAQ

Procurement & forensic-workflow questions.

What is a forensic Faraday bag used for?
A forensic Faraday bag is a signal-blocking container used in digital forensics to preserve seized electronic devices in their on-scene state. The moment a phone or laptop is placed inside, all wireless connections (cellular, WiFi, Bluetooth, GPS) are severed — preventing remote wipe, password reset, location signaling, and any over-the-air data modification. The device's chain of custody is preserved from seizure through laboratory analysis. Federal and state law enforcement, defense contractors, and corporate-security incident-response teams all use Faraday bags as standard digital-forensics equipment.
Does the REVIS-1 meet U.S. law-enforcement procurement specifications?
The REVIS-1 is tested to 76–85 dB attenuation across 30 MHz – 10 GHz using IEEE-299 methodology, with reference to MIL-STD-188-125 for the relevant frequency bands. The shielding test report is provided on letterhead and meets the documentation requirements of most federal, state, and local LEA procurement standards. For agency-specific compliance audits, independent third-party verification (Keystone Compliance) is available on request. The product is fully U.S.-manufactured for buyers with country-of-origin procurement requirements.
What does the chain-of-custody workflow look like?
On scene, the device is removed from the suspect or recovered from the location; the case officer places it directly into one of the REVIS-1's three independent chambers. The chamber is sealed with the Velcro closure. The bag is tagged with the case-evidence marker (custom-branded Velcro patch with agency identifier available for 10+ unit orders). The bag is transported to the forensics lab in this state. The forensic examiner opens the chamber under controlled conditions in a faraday-isolated examination room — at no point in this workflow does the device reconnect to a network, GPS, or cellular tower.
Can I prevent remote wipe with this bag?
Yes — and this is the primary procurement justification for forensic Faraday bags. Modern smartphones (iOS, Android) support remote-wipe commands triggered from the manufacturer's cloud (Find My iPhone, Find My Device) or from MDM platforms (Jamf, Microsoft Intune). The wipe command requires a network connection. Inside the REVIS-1, the device has no cellular, no WiFi, and no GPS — so the wipe command cannot reach the device. The on-scene state is preserved until the examiner has a forensic image.
How many devices does one REVIS-1 hold?
Three independent shielded chambers. Chamber 1 holds a laptop up to 16-inch (MacBook Pro 16, ThinkPad equivalent). Chamber 2 holds a tablet (iPad Pro 13) and a phone (iPhone, Galaxy) simultaneously. Chamber 3 holds smaller items: secondary phone, key fobs, RFID credentials, USB drives, smaller media devices. For a single-suspect intake, this typically covers the on-scene electronic evidence in one bag. For multi-device intakes or large-scale operations, agency bulk orders (10+ units) at unit pricing are the standard procurement path.
Do you support GSA Schedule or federal contract vehicles?
Direct GSA Schedule listing is in process; pending listing, federal procurement is supported via bulk-order contracts at standard agency pricing (10+ units include custom-branded Velcro patches with agency identifier at no setup or tooling fee). For procurement officers requiring SAM.gov registration verification or specific solicitation responses, please contact our team at info@revis-1.com with the agency procurement request and a 24-hour response will be provided.
How does the REVIS-1 compare to EDEC OFFGRID or Mission Darkness for LEA procurement?
EDEC OFFGRID and Mission Darkness are both well-established forensic-bag suppliers with strong federal procurement track records. EDEC's strength is its ISOTech fabric and chain-of-custody-aware design. Mission Darkness's strength is its product range and Made-in-USA fabric program for select SKUs. The REVIS-1's positioning is different: a structured executive briefcase form factor with three independent chambers, designed for both forensic procurement and the executive-protection-detail use case. For agencies that need a procurement format that doubles as a discreet carry product (executive protection, principal-protection details, corporate-security teams), the REVIS-1 is operationally distinct from forensic-only products. For pure forensic procurement, EDEC or Mission Darkness may also be evaluated. See our Best Faraday Briefcases 2026 buyer's guide for the cross-brand comparison.
Are NDAs and confidentiality agreements available for sensitive procurement?
Yes. Standard NDA template is available immediately, or REVIS-1 will review and sign your agency's NDA template for any quote over $25,000. Discreet packaging without REVIS-1 branding on the outer box is included by default for orders 100+ and available on request for smaller orders. For sensitive procurement requiring discreet shipping addresses or third-party shipping coordination, contact info@revis-1.com.
What is the lead time for an agency bulk order?
Standard lead time is 4–6 weeks from approved patch design to delivery for orders of 10–500 units. Larger orders (500+) ship in production batches with a phased delivery schedule. Pre-production samples are provided free for orders of 100+ units before mass production. For time-critical procurement (active-investigation outfitting, post-incident response equipment), expedited 2-week production is available at additional cost — contact info@revis-1.com for specifics.
