SDKontrol · a Regulayer surface
SDKontrol is the runtime engine, licensed as infrastructure. It runs any model, yours or a third party's, sealed and local inside the buyer's own environment, architected to make no outbound call, and it signs a record for every decision. The model travels. The data stays.
For two decades the answer in regulated markets was the same. The vendor could not promise the data would not leave, so the buyer said no. Banking, pharma, defense, healthcare, legal, semiconductor. The dealbreaker was always the outbound call.
SDKontrol removes it. The vendor ships its model sealed inside the customer's environment, runs every inference through the gate, and produces a signed record for every decision. The customer gets the evidence. The vendor gets the customer it could not reach before.
The buyer of SDKontrol is the vendor. What the vendor buys is the customers it could not reach. Validation, procurement and model-risk review still apply; this removes the egress objection, not the others, and it is honest about that.
The kernel binds the loopback interface and refuses any client that is not local. The signing key is generated on your own machine on first run and never leaves it. In the default mode there is no outbound call of any kind. Where independent time is required, a single cryptographic digest goes to a public timestamp authority, never the file and never its contents. The source ships readable, so your own security function can satisfy itself line by line.
Every answer your security function will ask for, on one page you can forward
Describe the system, what it decides, and what it would cost you to be unable to prove it. A written scope follows before any call.
