Now in public beta

The infrastructure layer your devices are missing.

Edge-native PKI. Staged OTA rollouts. Live log streaming. Fleet telemetry on constrained devices. Koios is the operations layer between your firmware and your fleet.

Edge-Native PKI

Issue, rotate, and revoke device certificates — backed by HSMs, not hope.

Every device in your fleet gets a real X.509 certificate, issued from a chain of trust you control, authenticated with mutual TLS, and backed by keys that live in hardware security modules.

  • HSM-backed Key Encryption Keys
  • Bring Your Own CA or Managed CA
  • mTLS device authentication
  • Automated certificate lifecycle
  • Bulk factory provisioning
  • CRL/OCSP revocation

OTA That Doesn't Brick Your Fleet

Canary → Staging → Production. Roll back in seconds if something breaks.

Define rollout rings and promote firmware through them as confidence builds. Health-check criteria gate every stage. If a canary device reports issues, the rollout pauses automatically.

  • Configurable rollout rings
  • Health-gated promotion
  • Automatic rollback
  • Encrypted firmware storage
  • Delta updates for bandwidth savings
  • CI/CD pipeline integration

See Inside Every Device

Memory usage, stack depth, heap fragmentation — from 5,000 miles away.

Real-time and historical telemetry from every device in your fleet, including constrained microcontrollers. Fleet-wide aggregation with per-device drill-down.

  • Memory and CPU telemetry
  • Reboot reason classification
  • Custom application metrics
  • Fleet-wide aggregation
  • Threshold-based alerting
  • Lightweight MCU agent

Stop Shipping USB Cables

Stream logs from devices with kilobytes of RAM. Search, filter, alert in real time.

Structured log delivery from every device — even the ones running on a few kilobytes of RAM. Full-text search, severity filtering, and deployment correlation across your entire fleet.

  • Real-time log tailing
  • Structured key-value logging
  • Full-text search via OpenObserve
  • Automatic device context tagging
  • Deployment correlation
  • Configurable retention policies

What you'd build yourself — if you had six months and an infrastructure team

Most IoT teams duct-tape five services together. Koios replaces the patchwork.

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.
