What Is a Forensic RF Shield Box

A forensic RF shield box is a secure enclosure designed to block all wireless communication signals from reaching electronic devices placed inside it. In other words, it acts as a controlled Faraday cage that prevents signals such as cellular, WiFi, Bluetooth, and GPS from entering or leaving the enclosure.

As a result, investigators can safely handle and analyze devices like smartphones without the risk of outside interference or accidental data loss. Additionally, the isolated environment helps preserve evidence exactly as it was at the time of collection.

Why Is RF Isolation Important in Digital Forensics?

When a device is seized during an investigation, it often remains connected to wireless networks. Because of this, several serious risks can occur, including:

Remote wipe commands that can erase critical evidence
Unauthorized access to the device
Automatic syncing or deletion of data
Location tracking or signal interference

Therefore, a forensic RF shield box is essential because it creates a fully isolated environment. This isolation ensures the device remains protected and unchanged throughout the forensic process.

What Is a Forensic RF Shield Box Used For?

RF shield boxes are commonly used to secure smartphones, tablets, and other wireless-enabled devices immediately after they are collected as evidence. Furthermore, they support several critical forensic functions.

Preventing Remote Access and Data Tampering

By blocking all incoming and outgoing signals, investigators can ensure that no outside commands alter, erase, or compromise the data stored on the device.

Supporting Secure Data Extraction

In addition, devices can remain connected to forensic tools such as GrayKey or Cellebrite while still being fully isolated from wireless networks.

Enabling Hands-On Analysis

Many forensic RF shield boxes also include built-in RF shielded gloves. Consequently, investigators can interact with the device safely without removing it from the enclosure.

Maintaining Chain of Custody

Most importantly, using a controlled and secure environment helps preserve the integrity of evidence for both legal and investigative purposes.

Key Features of a Forensic RF Shield Box

Most forensic RF shield boxes include:

High RF shielding effectiveness across multiple frequencies
RF filtered interfaces such as USB, Ethernet, and power
Viewing windows for real-time monitoring
RF shielded gloves for safe interaction
Compatibility with multiple device types

STE3000 Series – Forensic RF Shield Boxes

Multiple Models Built for Different Forensic Needs

The STE3000 Series forensic RF shield boxes are specifically designed to support a wide range of digital forensic workflows. Because multiple models are available, investigators can select the configuration that best fits their operational requirements.

For example, the series includes models with USB 2.0 and USB 3.1 Gen 2 interfaces, as well as optional Ethernet connectivity for GrayKey integration and video or DVR recording capabilities. Additionally, each unit is engineered for real-world use by allowing safe, hands-on interaction through RF shielded gloves and a clear viewing window.

Consistent RF Isolation Across the Series

Every enclosure in the STE3000 Series is constructed using heavy-duty aluminum, GEN-2 RF gaskets, and RF absorbent foam. Together, these materials provide reliable and consistent RF shielding performance across all models.

As a result, the series is engineered to block:
