Shielded Signals Mesh Appliance
private off-grid communications
encrypted text messaging — simplified.
Powered by Meshtastic. Secured by Shielded Signals.
When cell towers go down, storms hit, or the grid fails, you shouldn’t lose the ability to communicate with the people who matter most. The Shielded Signals Mesh Appliance brings private, encrypted texting to families, farms, teams, neighborhoods, CERT groups, and anyone who wants reliable communication — without depending on the Internet.
No tinkering.
No configuration rabbit holes.
No guesswork.
Just a secure appliance that works when everything else doesn’t.
Why Off-Grid communications matters during emergencies
Most of us take cell phones and Internet for granted — until they fail.
And they do fail.
Winter storms and blizzards
Tornado outbreaks
Power grid failures
Rural dead zones
Overloaded cell towers during emergencies
Infrastructure failures
When communication is critical, you shouldn’t be left in the dark. Our Mesh Appliance gives your family or group a completely independent way to exchange messages, even when every other system is down.
Why We Chose Meshtastic as Our radio Transport Layer
Shielded Signals evaluated multiple technologies before choosing the backbone for our mesh appliance. Meshtastic stood out because it is:
Proven and Stable
A large, active community constantly improves the software.
Efficient and long-range
LoRa radio technology makes it possible to send messages miles away using very little power.
Reliable in real-world conditions
It’s already used by hikers, ranchers, CERT teams, and off-grid communities.
Supported by a wide base of hardware
Availability matters! customers shouldn’t have to hunt for parts.
How Shielded Signals builds on, but is Not, Meshtastic
Meshtastic is an amazing open-source project.
But it was built for tinkerers, not for everyday families or for people who want a communications system, not a hobby.
The Shielded Signals Appliance is different by design:
No Apps to Install
Connect with your phone, tablet, or laptop using wi-fi and a broswer. done.
No confusing menus or settings
The appliance handles everything for you.
Always On Private channels
Each appliance is pre-configured to communicate only with other Shielded signal appliances, giving you a private network of your own.
A hardened, curated experience
We manage the firmware, the encryption keys, the channel logic, and the reliability — not the customer.
Purpose-built for normal people
Families. Neighborhood groups. CERT teams. Small businesses. Preparedness groups.
“Meshtastic provides the road to get you to your destination.
Shielded Signals is the vehicle that gets you to your destination safely, securely, and privately.”

Two Locks. One Message. Double encryption.
Most Meshtastic deployments use a single encryption key — which is widely known, often unchanged, and shared across entire regions. Shielded Signals adds a second layer of protection.
Meshtastic ChaCha20-Poly1305, 256-bit encryption (standard layer)
The encryption level available by default on all meshtastic traffic, and available to all nodes on the network.
Shielded Signals private key encryption (exclusive layer)
Your messages are:
Protected at the radio level
Protected again at the Shielded Signal Level
Isolated and private from anyone outside of your group
unreadable to anyone not part of your ecosystem
it’s like having two locks on every message you send. Your communication stays YOURS.
Introducing the Shielded Signals Mesh Appliance (coming early 2026)
A simple, secure device for off-grid text messaging, ready for families and teams who want communication — not configuration.
You don’t need to understand radios.
You don’t need to install special apps.
You don’t need to manage keys or channels.
Just plug it in, connect with your phone or laptop, and send encrypted messages to your group.
A First Look at the mesh appliance Interface - simple and secure
This is a pre-release version of the interface, and may change prior to final release.
The appliance provides a clean, simple dashboard, allowing the user to:
Send group or direct messages
see which devices are online
switch channels
monitor message activity
configure Wi-Fi settings
Reboot easily and cleanly
any user that can handle a basic website can handle this interface.
designed for real people - not just hobbyists
The world of DIY mesh radios is exciting! it is only because of the hobbyists that have built, and will continue to enhance, the meshtastic network that we can provide something like this appliance.
But for families or groups that just want a private communications system that works out of the box with minimal configuration, a standard meshtastic node should not be your first choice.
