When Encryption Isn’t Enough: Why Human Behavior Still Decides Security
CISA’s latest spyware warning shows that attackers aren’t breaking encryption — they’re targeting the humans using it. Strong tools matter, but layered security and disciplined behavior matter even more. Here’s why off-grid systems like Shielded Signals reduce those risks.
FRS vs GMRS vs MURS vs PoC vs PRaaS™ — And When Each One Fails You
FRS vs GMRS vs MURS vs PoC — and why most “off-grid” radios fail when storms hit. Learn how PRaaS™ provides encrypted, reliable communication when every other system goes down.
Above the Clouds, Below the Radar: Why Satellite Comms Aren’t as Private as You Think
Satellite communication isn’t as private as people think — researchers have shown just how easily unencrypted signals can be intercepted from orbit. Shielded Signals explains why encryption, not altitude, defines real security.
When the Cloud Sneezes
Yesterday’s AWS outage showed how fragile our connected world really is. When the internet hiccups, most systems stall. But Shielded Signals radios keep working. Learn why off-grid, encrypted communication matters now more than ever.
Why PRaaS™ Beats GMRS, MANET, and Even HAM Radio for Local Off-Grid Communications
Preppers, radio operators, and emergency planners have more communication options than ever (GMRS, HAM, MANET). But only PRaaS™ combines encryption, simplicity, and legal authorization under a managed network. Here’s why it’s the smarter choice for true off-grid reliability.
