The Update Problem Nobody Talks About

A single insecure update can brick thousands of devices—or worse, leak your IP. Building it in-house costs months, risks outages, and rarely passes modern CRA/ISO security requirements.

  • Connectivity edge cases & bricked devices
  • Lack of rollback logic & audit trails
  • Exposed signing keys & weak identity management

Security Risks

Tampering, replay attacks, and downgrade exploits are common in home-grown solutions.

Time Sink

6-9 months of engineering time wasted reinventing the wheel instead of shipping features.

Reliability

Handling partial downloads and delta updates on NB-IoT/LoRaWAN is mathematically hard.

Compliance

New EU CRA regulations require strict SBOMs and update capabilities.

Two Deployment Models

Built by embedded engineers for embedded engineers. Choose the level of sovereignty your industry demands.

Full-Hosted OTA

SIMPLICITY FIRST

Upload your firmware to our secure cloud. We handle storage, CDNs, manifests, and delivery. Perfect for fast-moving teams.

  • Encrypted Object Storage (S3/R2)
  • Auto-Manifest Generation
  • CDN-backed Global Delivery

Zero-Trust OTA

ENTERPRISE & DEFENSE

Your binary. Your server. Your sovereignty. Our backend signs the metadata, but your firmware binary never touches our infrastructure.

  • You host binaries (MinIO/S3/On-Prem)
  • We sync metadata only (Hashes/Rules)
  • Even if we are hacked, your IP is safe

The IO-SEC Trust Model

Most platforms just push files. We push trust. Every update is cryptographically verifiable and resistant to tampering, replay, or downgrade attacks.

Secure Bootloader SDK

Verified boot using Ed25519/ECC/RSA. SHA-256 integrity checks. Anti-rollback monotonic counters. Drop-in support for Zephyr & FreeRTOS.

Per-Device Identity

Each device carries a long-term cryptographic identity (X.509 or Ed25519 keypair), bound to hardware model and allowed version policies.

AI-Driven Rollouts

Orchestration engine predicts failure probability. Canary stages auto-pause on anomalies. Real-time SSE metrics for fleet health.
