Listen First

Poke an old controller too hard and you can knock out the corner you came to protect.

ILLUSTRATIVE

The security team wants to scan the signal network to see what's on it. The signal operations manager asks one fair question.

"What happens if a controller doesn't like being scanned?"

Nobody in the room has a good answer.

She's right to ask. Many controllers in the field are ten or twenty years old. They were built to run lights, not to handle a flood of probes from a security tool. An aggressive scan can freeze one, or trip it into flash. The very act of checking for risk becomes the risk.

So Findavi starts by listening.

The Findavi appliance sits where your signal network comes together, often at the traffic center, and connects to a port that copies the network traffic you approve. It sends nothing to your controllers, radios or cameras. It hears what they already say to each other every day and builds a picture from that.

From listening alone, it can tell a lot. Which devices are on the network. What they are. Who each one talks to. Which ones still use default logins or send passwords in the clear. Which ones can be reached from places they shouldn't. Which ones are suddenly talking somewhere new.

The AI that does this runs on the appliance itself. No outside AI. The network data never leaves your agency.

The Findavi appliance can hear the radio too. Connected to an RF switch, it can watch wireless activity in range of that switch.

One honest limit. Findavi sees only the parts of the network it's connected to. A corridor whose traffic never passes the appliance is still invisible. Every assessment says plainly what it covered and what it didn't.

Coming next: a guard inside the box. We're building a small sensor that sits in the signal cabinet itself and watches the controller's traffic right at the corner. It only listens. It can't send commands, change settings or block anything, so it adds no new way in.

Ask your team: When did someone last check our list of controllers, radios and cameras against what's actually plugged in?
