PROVEN FRAMEWORK
Our Delivery Methodology
We deliver secure, verifiable firmware updates for embedded devices using a battle-tested process that ensures zero-downtime deployments and cryptographic integrity.
01
Cryptographic Identity Bootstrapping
We provision your devices with unique, hardware-backed cryptographic identities (using TPM, HSM, or secure enclave) at manufacturing. This establishes a root of trust for all future OTA updates.
FIPS 140-2
Compliance
Zero-trust

Secure Update Orchestration
Our system manages the complete update lifecycle: version control, dependency checks, staged rollouts (canary/blue-green), and automatic rollback on failure—all signed and verified on-chain.

OTA Firmware Identity Updates
Frequently Asked Questions
Get clear answers on how we secure and manage device identities through over-the-air updates for Web3 and IoT projects.
We implement a multi-layered security model. All firmware images are signed using hardware-backed keys (HSM/TEE) and verified on-device before installation. We use cryptographic attestation (e.g., Sigstore, Notary v2) and secure boot chains to prevent unauthorized code execution. Our process is based on frameworks like The Update Framework (TUF) and Uptane, with all code undergoing third-party audits.
