Koios

Ship devices. Not infrastructure.

Koios is the operations layer between your firmware and your fleet. PKI. OTA. Logs. Telemetry. One platform.

Certificate chain of trust iconDevice Identity

Device identity, hardware-rooted.

HSM-backed X.509 certificates. mTLS on every connection.

Bring your own CA or use ours. Your keys never leave the HSM. Every device gets a unique certificate from a chain of trust you control.

  • HSM-backed Key Encryption Keys
  • Bring Your Own CA support
  • mTLS on every connection
  • Automated certificate rotation
MCU firmware update iconFirmware Delivery

Push firmware like you push code.

Canary rings. Health gates. Automatic rollback.

Delta updates for constrained networks. API-driven, so it plugs into your CI. Progressive rollout from canary to production.

  • Staged rollout rings
  • Health-gated promotion
  • Automatic rollback
  • CI/CD pipeline integration
Device observability terminal iconObservability

Stop guessing. Start observing.

Memory, CPU, reboot reasons, and custom metrics.

Even from devices with 64KB of RAM. Fleet-wide trends. Per-device drill-down. Threshold-based alerting before issues become incidents.

  • Memory and CPU telemetry
  • Reboot reason classification
  • Fleet-wide aggregation
  • Threshold-based alerting
Wireless log streaming iconLogging

Every log line. Every device. Real time.

Structured logging from embedded devices that can barely afford a malloc.

Full-text search. Deployment correlation. No MQTT broker required. Stream logs directly from constrained devices to managed OpenObserve.

  • Real-time log streaming
  • Full-text search
  • Deployment correlation
  • No MQTT broker required
"We were three weeks into building our own OTA system when we found Koios. We had the entire thing running in an afternoon."

Security isn't a feature. It's the architecture.

Built on infrastructure you already trust. Every byte encrypted at rest and in transit. Keys stored in dedicated HSMs. We don't sell your data. Full stop.
