The GoDark® Faraday Sleeve for Laptops (M) is a purpose-built shielding pouch designed to completely block all wireless signals to and from your laptop, including Wi-Fi, Bluetooth, cellular, GPS, and RFID. Constructed with GoDark’s proven multi-layer Faraday fabric, it prevents remote access, tracking, data exfiltration, and unauthorized activation of your device’s microphone or camera the moment it’s inserted.
Trusted by security researchers, investigators, attorneys, executives, and privacy-conscious professionals, this sleeve is an essential tool for evidence preservation, sensitive document handling, and secure transport of devices in hostile or high-risk environments.
- Blocks all wireless signals including Wi-Fi, Bluetooth, GPS, cellular, and RFID
- Prevents remote triggering, tracking, and unauthorized data access
- Supports forensic integrity and chain-of-custody best practices
- Lightweight and portable for everyday carry and field use
Why a laptop needs its own shielded enclosure
People think about phones and forget laptops, which is backwards for anyone handling sensitive work. A laptop carries orders of magnitude more data, maintains its own cellular or Wi-Fi connections, runs management software capable of remote wipe, and in many corporate configurations can be located, locked or erased by an administrator at any moment.
A Faraday sleeve sized for a laptop removes all of that with a conductive barrier rather than a software setting. Sealed inside, the machine cannot reach a network and no network can reach it — regardless of what is installed on it, what policy applies to it, or whether it has been compromised.
The uses that justify it
Evidence preservation. A machine seized or surrendered in an investigation, an employment dispute or litigation must be isolated from networks immediately. A connected laptop can be wiped remotely, can sync deletions from a cloud account, and can accumulate new data that alters the state being preserved. Isolation is standard forensic practice and a shielded sleeve is how it is done between collection and examination.
Transport through uncontrolled environments. Travel, hotel stays, shared offices, conferences and border crossings all involve periods where a machine is out of your direct control. A sealed sleeve means the device is not reachable during those periods and is not reporting location.
Sensitive meetings. A laptop with a microphone and camera in the room is an exposure whether or not anyone intends it. Sleeving devices before a privileged discussion removes the question.
Working for clients with real adversaries. For investigators, attorneys handling contentious matters, executives and anyone whose movements or communications are of interest to an opposing party, controlling when a device can be reached is a basic operational discipline rather than an exotic one.
Sizing: measure the machine, not the marketing size
Screen size is a poor guide to physical dimensions. A thirteen-inch machine from one manufacturer and a fourteen-inch from another can have nearly identical footprints, and a thick gaming or mobile-workstation laptop of a nominally smaller class may not fit a sleeve cut for a slim ultrabook.
Measure your laptop’s length, width and thickness, add any case or sleeve you keep it in, and compare against the internal dimensions listed in the specification above. Allow room to close the seal properly — a device that fills the enclosure to its limit makes a proper roll and fold difficult, and a hurried closure is where shielding fails.
Closing and verifying
The seal is the product. Roll the closure the specified number of turns and press firmly across the full width; a partial fold or a lifted corner leaves a gap, and a gap is a path.
Verify rather than assume. The simplest field test is to leave the machine connected to a network, seal it, and confirm from another device that it has dropped off — or, on a machine with cellular, call or message it and see nothing arrive. Repeat the test every few months. Conductive fabric degrades with repeated creasing along the same lines, and a sleeve that has been folded and unfolded hundreds of times is not the sleeve you tested when it was new.
Two behaviours to expect. A device that cannot find a network searches harder and drains battery faster, so a long shield costs charge. And the machine will reconnect and report the moment it comes out, so where you open the sleeve is part of the plan.
Forensic handling, if that is why you are buying
If the device is evidence, the sleeve is one step in a process. Document who collected it, when, from where, and who has held it since — chain of custody is what makes the examination usable later. Do not browse the machine “just to check”; every interaction changes state and can be challenged. Do not power it down or up outside a controlled process, because both actions can trigger encryption states, scheduled tasks or logging that complicate examination.
Seal it, document it, and hand it to someone who does this properly. Our digital forensics and incident response team handles acquisition, analysis and reporting to a standard that holds up.
Care
Store the sleeve loosely rather than folded flat under weight. Keep sharp objects, charger bricks with exposed pins and anything abrasive out of it. Avoid leaving it in a hot vehicle. Inspect the closure surfaces for wear and retest periodically — these are long-lived consumables, not permanent equipment, and the failure mode is silent.
What it does not do
It shields the machine while it is sealed inside and at no other time. It does not remove malware, undo a compromise, protect a cloud account reachable by anyone with the password, or substitute for full-disk encryption and a strong passphrase. It controls reachability — which is a specific, valuable thing, and only that thing.
