If you have sensitive information on a portable electronic device or heavily rely on the use of an electronic device for communication, navigation, and information gathering- then a Faraday bag is a sound investment.

Signal disruption events are improbable but not uncommon.

Nuclear events, such as attack detonations and EMPs are wide-scale disaster situations that cause electromagnetic interference. Space weather, such as CMEs, can also cause widespread damage to electronics.

Localized events, such as RFID hacking and signal tampering, can be more probable for high-risk individuals. Military, law enforcement, and high-profile businesspersons can be targets for these attacks given the sensitive nature of their work. GPS tracking can also be blocked with a bag.

The combination of the importance of portable electronic equipment to both our security and survival makes a Faraday bag a good opportunity to strengthen your preparedness against these threats.
