Smart Home Security is Broken

Current IoT security solutions are expensive, complex, and lock you into proprietary ecosystems. There has to be a better way.

💰

Subscription Fatigue

Monthly fees for basic security features add up to hundreds per year

🏠

Hub Dependency

Expensive hubs that become single points of failure in your security system

🔒

Vendor Lock-in

Proprietary apps and protocols trap you in closed ecosystems

Power Hungry

Devices that drain batteries quickly, requiring constant maintenance

🛠

Complex Setup

Hours of configuration and technical knowledge just to get started

📱

App Overload

Another app cluttering your phone for each brand of smart device

💡

What if security was simple?

Imagine sensors that just work. No subscriptions, no hubs, no proprietary apps. Just stick them anywhere and get instant notifications when something moves.

How It Works

Hardware-signed events create an immutable chain of proof. No cloud trust required — verify directly from the cryptographic signature.

01

Deploy & Register

Register your ESP32-C6 device with a shared HMAC secret. Plug in, connect to Wi-Fi, done.

02

Events Get Signed

Sensor events are HMAC-SHA256 signed on-device before leaving the hardware. Tamper-proof by design.

03

Verify Anywhere

Every event gets a public proof URL. Tap the NFC tag or check the dashboard — cryptographic proof it happened.

Built for Trust

Hardware-Signed Events

HMAC-SHA256 signatures generated on the ESP32 chip. Events are authenticated before they leave the device.

NFC Proof of Presence

Physical NFC tap creates cryptographic proof someone was at a specific location at a specific time.

Public Verification

Every event has a shareable proof URL. Third parties can verify without needing an account or API access.
