Yes, it is secure & risk free:
We use end-to-end, chip-level encryption to secure our devices. No security incidents have been reported from any of our hosts. In addition to this:
• Only authorized IoT devices can connect. (You can’t even connect to your own hotspot.)
• Hotspots don’t have any listening devices or cameras, so your privacy is always ensured. There is zero access to any of your data on your network.
• The encrypted data is secure on multiple layers of hardware and software, providing maximum security and complete protection from inbound port attacks.
Security of networks is our highest priority. Please refer to this Network Security Overview
for information on what we do to keep the Helium Network safe and protected.
