First they shut down your ability to call for help. Then they come in.
A single jammer cuts off, all at once, the panic button, the alarm, the sensors and your staff's radios. JammerDefense makes that silence visible, so you know you are under attack while it is happening.

Illustrative image of the JammerDefense sensor installed on the wall of a bank lobby, with a spectrum monitor on top: the signals of the security systems, a jamming attack that covers them, and Tank's detection.
The problem
They are still on. And silent.
None of them warns you it is being jammed. And a jammer doesn't have just one shape. Looking won't help. Detecting the emission will.

Tank JammerDefense
They are still on. None of them warns you it is being jammed.
What changes with JammerDefense
- 01
You know you are under attack while it happens.
The silence of your systems becomes an alert, in time to act.
- 02
Your team goes to the right place.
With One you know the zone, with Sector the floor and with Hyperlocation an 8×8 m square.
- 03
You get a record that holds up.
Tank Mission Control records the dispatch, the closure and the validation.
In the field
8×8m
precision with Hyperlocation
Even in the worst case: an enclosed parking garage, where the signal bounces and gets absorbed.
53ha
coverage with one sensor
Up to 53 hectares with one sensor (about 131 acres), a radius of 410 m.
Protects the infrastructure your security takes for granted
JammerDefense doesn't protect an object. It protects the systems your site uses to call for help.
Configurations
From the whole zone to the exact spot.
What you know
That there is an attack, and in which zone
What your team does
Your team sweeps the zone
What you know
Which floor or sub-zone
What your team does
Your team goes to the right floor or sector
What you know
8×8 meters, even in the worst case
What your team does
Gets there almost on top of it
Hyperlocation is not a separate device: it is a way of configuring the same sensors. A more affordable deployment does not protect less, it protects more slowly.

Law 21.720
Since December 2024, Chile's Law 21.720 makes it a crime to sell, carry or use a signal jammer. Tank doesn't replace the security you already have; it makes it work again.
Frequently asked questions
How is it different from CarDefense?
CarDefense protects visitors and their vehicles. JammerDefense protects the building's security infrastructure, which is why it covers many more technologies than a car.
Does it include handheld detectors?
Not for now. In these scenarios the attack becomes evident on its own, and what matters is knowing in time.
I already have an electronic security provider.
Your provider depends on the layer that is being attacked. JammerDefense doesn't replace them; it protects what they already sold you.
Also in Tank Civil
Protects the visitors of a large venue and their vehicles.
