About
Combotto.io helps engineering teams design and scale secure IoT data infrastructure — from STM32 edge devices and MQTT layers to cloud analytics and observability.
Built on Rust, Scala, and Python with Linux automation at the core, Combotto.io delivers reliability, security, and long-term maintainability — turning complex IoT networks into resilient, production-ready systems
Core Technologies
Avoid telemetry loss — local WAL buffering and MQTT QoS keep your data consistent even during outages.
Deploy on AWS, Azure, or self-managed Kubernetes. No vendor lock-in — integrate with Kafka or NATS seamlessly.
Built-in zero-trust identity, mutual TLS, and audit-ready traceability across your IoT pipeline.
Process
20-minute strategy call to confirm scope, devices, data rates, and SLAs.
Structured infrastructure audit with prioritized action plan.
Reliability sprint: secure MQTT gateway, observability, dashboards.
Demo
End-to-end telemetry pipeline with local WAL buffering, zero-trust device authentication, and OpenTelemetry tracing to Grafana Tempo. Vendor-neutral IoT observability from device to dashboard.
Traces and dashboards are shown in the visual gallery.
