Security
Your data stays home.
Henselian is installed where your data already lives. We never see it, nothing needs the internet, and every decision leaves a receipt.
Seven promises, each one checked against the code.
It runs on your servers
The engines run on servers you control, reached over SSH. Nothing is exposed beyond the access you already have, and we have no way in unless you invite us.
It works without the internet
Everything Henselian needs, including the assistant, is installed on your machines. It works on a network cut off from the internet.
Every decision has a receipt
A decision goes on a record that cannot be changed without it showing: the data, the assumptions, the steps and who approved it. An auditor can run it again and get the same answer.
A person confirms before the record
Approving a decision asks the person at the machine first, with Touch ID or the machine's password. Cancel, and nothing is recorded.
On macOS today.Keys stay in the system's store
The keys that reach your engines and your trading venue live in the Keychain, never in a config file.
On macOS today.Servers are checked before they are trusted
A server the app has never met shows its host key first, to be checked once with its administrator. A key that changes is refused, with no button to override it.
Updates are signed, and yours to time
The app verifies a new version against its signing key before installing it, and installs it when you choose. Past results stay exactly as they were.
What security teams ask first
Ask us anything else. A person who builds the engine will answer.
Talk to usDo you ever see our data?
No. Henselian runs on your servers, so your data stays with you. We have no way in unless you invite us, and then only for the time and the task you agree to.
Do we have to replace the models we have?
No. We start from a question you already answer today and run it beside your current model, so you can compare the two, number by number, before anything changes.
Can it run without internet access?
Yes. Everything it needs, including the assistant, is installed on your machines, and it works fully on a network cut off from the internet.
How do auditors check a result?
They open its receipt: the data, the assumptions, the steps and who approved it. They can run it again and get the same answer.
What does a first project look like?
One question that takes too long today. We model it on a synthetic book shaped like yours, run it with you at full size, and you decide what happens next.
We cannot prevent every storm. We can help you prepare before it arrives.
Bring us the simulation your organisation wishes it could run faster. We will show you what is possible, on a book shaped like yours.
