Frequently Asked Questions

When does it ship?

We're targeting Q4 2026 for the first production run. Pre-order customers ship first. Your $49 deposit is fully refundable at any time before shipment.

How does it work?

BlueGuard plugs into any USB-A port. It begins scanning for Bluetooth threats within 500ms — before your operating system even starts loading. It uses the same nRF52840 BLE chip used in professional security tools, combined with a dedicated ARM Cortex-M4 processor and ATECC608A secure element for cryptographic boot verification.

What attacks does it detect?

BlueGuard detects 6+ known BLE attack families including BlueBorne (remote code execution), KNOB (key negotiation), BLUFFS (session hijacking), BrakTooth (DoS), BlueFrag (Android RCE), and SweynTooth (IoT exploitation). The firmware signature database is updatable.

Do I need the iOS app?

No. BlueGuard works standalone — the USB device protects you automatically. The iOS companion app adds real-time monitoring, threat alerts, and device whitelisting for enhanced visibility.

Is my deposit refundable?

Yes, 100%. Your $49 deposit is fully refundable at any time before your device ships. The remaining $100 is charged at shipment.

Who's behind BlueGuard?

BlueGuard is built by Philip S. Wright, founder of BlueGuard Security LLC (California). Philip is a cybersecurity engineer with expertise in Bluetooth security, embedded systems, and privacy-focused infrastructure. Patent prosecution is handled by Traverse Legal, a registered patent law firm.
