DefenderShield Faraday products use military-grade Ultra Armor™ shielding technology to block all wireless signals, including Wi-Fi, Bluetooth, GPS, and cellular. This creates what’s known as a Faraday cage - a protective barrier that stops signals from entering or leaving. Perfect for phones, tablets, laptops, and car keys, Faraday protection not only helps reduce EMF exposure but also adds an extra layer of security by preventing tracking, hacking, and digital theft. With DefenderShield, you get lab-tested, military-grade protection in practical everyday designs.
