Koios exists because every hardware team shouldn't have to build their own certificate authority, firmware update server, and log pipeline from scratch.
Every IoT project starts the same way. You design the hardware. You write the firmware. You get the prototype working on your bench. And then you realize you need to figure out how devices will identify themselves in the field, how firmware gets to them after they ship, how you'll know when something goes wrong, and how you'll read a log line without asking someone to plug in a USB cable.
So you build it. A self-hosted MQTT broker for messaging. A custom OTA server with no rollback. Let's Encrypt for certificates — if you bother with certificates at all. CloudWatch or a self-managed ELK stack for logs. A spreadsheet for tracking which device is running which firmware version. It works. Until it doesn't.
We built that stack enough times to know that it's the wrong use of an embedded team's time. The plumbing is the same across every project. The certificate authority, the firmware pipeline, the log aggregation, the device telemetry. It's undifferentiated infrastructure. It should be a platform.
So we built the platform. Koios is the device operations infrastructure we wished existed when we were shipping hardware. PKI, OTA, logs, telemetry — one platform, one API, one bill. So you can stop building plumbing and start shipping product.
Three principles that shape every decision we make.
PKI isn't bolted on after the fact. It's foundational to every device interaction — firmware delivery, log upload, API call. If you treat security as a checkbox, your fleet is a liability. We treat it as the load-bearing wall.
Your devices need infrastructure that works at 3 AM when nobody is watching. Not infrastructure that's innovative. We optimize for predictability, not novelty. The best infrastructure is the kind you forget is there.
We assume you know what mTLS is. The docs are the product. The API is the interface. No sales calls required to evaluate. No demo requests to see a dashboard. Sign up, read the docs, deploy a device.
The engineering principles behind the platform. These aren't aspirational — they're the constraints we build within.
Every device gets a unique cryptographic identity. Not a shared secret. Not a fleet-wide token. A real X.509 certificate from a chain of trust you control. If you can't distinguish one device from another cryptographically, you don't have device management — you have a broadcast channel.
The devices with 64KB of RAM are the ones that need observability most — and get it least. Every feature we build has to work on a microcontroller, not just a Linux box. If your telemetry agent requires more memory than the application firmware, you've missed the point.
Hardware teams exist to build products, not to maintain certificate authorities, firmware update servers, log aggregation pipelines, and device provisioning scripts. Every hour spent on infrastructure is an hour not spent on the thing your customers actually bought.
Canary rings, health gates, automatic rollback. Firmware deployment should have the same rigor as cloud deployment. "Push to everyone and pray" is how you end up on Hacker News for the wrong reasons. Staged rollouts aren't a luxury — they're the baseline.
Key Encryption Keys live in HSMs. Not in environment variables, not in config files, not in source control. There is no configuration option to store keys in software. Some decisions shouldn't be configurable.
Per-device pricing. Not per-message, not per-API-call, not per-certificate. No hidden egress fees. No "contact sales for pricing" on features you need. The price is on the website. The math is simple. If you need a calculator to estimate your bill, the pricing model is the problem.
Your device telemetry, your logs, your certificate metadata — it's yours. We don't sell it to advertisers. We don't feed it to analytics companies. We don't train models on it. We store it, we help you query it, and we delete it when you tell us to. Read the privacy policy — it's short, and it says exactly that.
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.
