Device Hardening
Close the doors attackers use on connected devices: locked debug ports, minimal services, least-privilege software, encrypted storage and secure defaults on embedded Linux and microcontrollers.
Readiness for devices already in the field
Recalls or hardware changes in field migration
Fleet monitoring and support
Secure OTA releases
The problem
Many devices ship with open debug ports, default passwords, unnecessary services and secrets stored in plain text.
Open debug access
JTAG, UART and shells left open on production units.
Too much running
Services, ports and tools the product does not need.
Exposed secrets
Keys and credentials stored unprotected on the device.
What we do
A hardening review of your device and the changes, built into your images and production process.
Debug port lockdown for production units
Minimal OS images and closed network ports
Least-privilege processes and sandboxing
Encrypted storage and protected keys
Secure defaults, no shared default passwords

A chain of trust from ROM to application, so devices only run software you signed. Ready for the EU Cyber Resilience Act.
Logs, metrics and crash reports from every device, so you find problems before customers do.
Give every device a unique, trusted identity from the factory to the cloud: keys, certificates and a PKI that handles provisioning, rotation and revocation across the whole fleet.
