Packet protection / live flow
Readable data goes in. Protected telemetry comes out.
Watch a sensor payload cross the link, pass through the Lightweight Cryptography gate, and arrive as ciphertext that an eavesdropper cannot read.

A novel, end-to-end VPN framework.
Engineered for IoT environments.
Built on standardized Lightweight Cryptography.
Delivering strong security guarantees.
Aligned with IoT system constraints.
Encrypted tunnel / scalable hub-and-spoke
Encrypted telemetry, built to scale.
Connected devices encrypt telemetry before sending it through authenticated tunnels to a central server, where it is verified, decrypted, and aggregated.

Products
Focused tools for secure, observable connected devices.
Meet the products building AspidIoT's security practice—from trusted device sessions to open tools that help the wider IoT community see the signal clearly.
Open source
BaudTide
Our open-source serial monitor for the greater IoT community—made for inspecting real devices, keeping raw capture local, and turning structured telemetry into a signal you can act on.
- Monitor multiple ESP32, Arduino, and USB/TTY devices.
- Visualize telemetry, filter noisy output, and export local logs.
- Share read-only terminal views over a trusted local network.
About
Research-led foundations presented with a product-first mindset.
Built as an FYP, AspidIoT explores how secure-by-design networking, authentication, and monitoring can be packaged into a practical platform for modern connected systems.
