About us

Shannon Cyber Services

CIAN is a product of Shannon Cyber Services, LLC — a security engineering practice based in Washington, DC.

Why we built CIAN

Coding agents changed how fast software can be written. They did not change what it costs to ship a Critical vulnerability, or to put a change in front of customers that no human ever looked at.

Most attempts to control that risk put the rule in the prompt and hope the model holds the line. It usually does — until the context is full, the change is urgent, or the agent decides the finding is a false positive. We work in security operations, where "usually" is not a control.

So CIAN puts the two rules that matter somewhere an agent cannot reach: the state machine that owns transitions between pipeline stages. An unresolved Critical or High finding stops the work. Nothing reaches done without a recorded human approval for that exact revision. Neither is a request, and neither has an override flag.

How we work

The same standard applies to how we describe what we have built. This site distinguishes what is built and tested from what is in progress and what has not been started, in the same list and in the same words — and a claim here that overstates what exists is a defect we would like reported. Our status list is the honest version.

CIAN runs on infrastructure you control. Your source code stays in your repositories and your issues stay in your tracker; we do not host your work, and we never handle your model credentials.

Get in touch

The support form reaches us for access requests, product questions, privacy and data requests, and anything on this site that looks wrong. We reply within 24–48 business hours.

If you have found a security vulnerability, describe it there without exploit details and we will follow up on a private channel.
