• Are you planning to buy a sleeve bag for your MacBook?
• Read on to find out whether a Faraday case sleeve could suit you more.

Originally, Faraday cage bags were used to block remote wiping of devices recovered in criminal investigations.

However, they are getting more and more popular among consumers as a way to protect against data theft or enhance privacy.

What is a Faraday cage?

▸ A Faraday cage blocks external electromagnetic fields and therefore protects content that’s placed inside.

▸ When an external electrical field is applied, it creates negative and positive charges within the cage’s conductive material. As a result, these induced charges cause the external field to be distributed withing the cage itself, cancelling its effect on the content.

What are the main features of Faraday cage sleeves and bags?

▸ Consumer Faraday bags offer a set of common features:

RF (Radio Frequency) protection – blocking WiFi, Bluetooth, cell signals including 5G networks, GPS, or RFID.
EMP (Electromagnetic Pulse) protection – blocking short bursts of electromagnetic energy, also caused by the human. An EMP can destroy any electronic that contains a microchip.
CME (Coronal Mass Ejection) protection – blocking magnetic field accompanying significant releases of plasma from the solar corona.

▸ Prices of Faraday bags designed for mobile devices – such as smartphones, tablets, or laptops – are higher than for standard sleeves. You can expect prices ranging from $15 to even $200.

▸ Some bags combine the features of Faraday cages with shock and scratch protection, as well as water and fire resistance.

Is a Faraday sleeve for MacBook worth buying?

▸ It’s worth buying a MacBook Faraday cage sleeve if you are concerned about the privacy and don’t want to lose the content of your laptop.

▸ A regular sleeve can protect only against mechanical damage to your MacBook, when you drop it or expose it to water or other liquids.

▸ A Faraday sleeve can also protect against the data loss being a result of a man-made EMP (Electromagnetic Pulse) attack. A short burst of electromagnetic energy can destroy any electronic equipment that contains a microchip.

▸ A Faraday sleeve that you get for your MacBook will be large enough also to put inside your iPhone, iPad, and other sensitive content.

▸ Some Faraday sleeves, besides EMP and CME protection, also offer RF blocking. It would be a way to save on buying a separate RFID blocking wallet. Simply, put RFID items (such as credit cards) inside the MacBook sleeve to prevent them from being penetrated by RFID scanners.

▸ Opposite to standard sleeves, many Faraday bags feature fire protection. Some bags can stand up the temperature up to 2000°F (1090°C).

▸ The biggest disadvantage of Faraday bags for MacBook is their high price. Some design cost between $100 and $200!

▸ When looking for a Faraday bag, make sure to read product details. Some items are described as Faraday bags, but don’t offer EMP and CME blocking.
