What Does a Faraday Bag Do?

Faraday bags provide you the benefit of having the same electronic protection that government operatives have for their mobile devices.

Most countries’ intelligence agencies have a group that specializes in SIGINT (Signals Intelligence) collection.

For example, the National Security Agency (NSA) has a group known as Tailored Access Operations (TAO) which are the only on-network operators within the NSA that are permitted to engage in offensive operations on the internet.

Within the TAO there is a department known as the Remote Operations Center. If the US Government needs to gain access to computer systems, networks, or mobile devices, the request goes to the ROC.

To ensure your mobile devices such as cell phones and tablets are not being tracked or hacked by these types of groups while traveling, the best practice is to store them in a faraday bag.

Are Faraday Bags Effective?

Faraday bags are effective as radio frequency blocking bags that stop Bluetooth, RFID, GPS, and Wi-Fi exploits without ever raising anyone’s suspicion.

The fact that you can take this security device with you anywhere without raising suspicions is another advantage. People around you will think that you’re carrying a nylon travel wallet or some sort of common bag.

Easily blending in improves your privacy, and not exposing your devices to hackers in the first place is an excellent security practice.

Do Faraday Bags Block 5G?

As 5G continues to grow, RF hacking is projected to become a large cybersecurity issue, as it can go under the radar of firewalls and network-based detection systems.

Most faraday bags are manufactured to be able to block the 5GHz RF spectrum. To ensure that it is, check the manufacturer’s specs before buying. All 3 faraday bags mentioned above block 5G.
