The hidden risks of connecting IoT devices to the public internet
Many companies mistakenly believe that a standard SIM card is sufficient for industrial deployments. However, exposing devices directly to the public internet makes them vulnerable to unauthorized access and cyberattacks. For critical operations, a Private APN is essential to isolate your cellular traffic from the public web.
At iot.cards, we solve the security challenge by providing M2M connectivity that combines private network identifiers with encrypted tunnels. This ensures your data travels through a secure environment, managed via our centralized management portal, without the need for risky public IP addresses.
Enterprise-Grade Security Features
VPN Tunneling
Establish a secure IPsec or OpenVPN tunnel between our core network and your corporate infrastructure for end-to-end encrypted communication.
Isolated Private APN
Your devices operate within a dedicated network segment, invisible to external scanners and shielded from automated botnet attacks.
Multi-Operator Roaming
Maintain your secure connection across 180+ countries with automatic switching between the strongest available carriers (4G, LTE-M, NB-IoT).
Global Secure Connectivity for Critical Assets
From remote industrial controllers to security camera systems, the need for a private network is universal across sectors. By implementing a VPN-backed architecture, you can achieve bi-directional communication with your devices securely, bypassing the limitations and security flaws of standard consumer-grade SIM cards.
Our solution is designed for rapid deployment. Whether you are managing logistics fleets or distributed smart energy meters, you get full visibility and control over your data usage with no permanent contracts and 24-hour activation times.
Public Internet vs. Private APN + VPN
| Feature | Standard Public SIM | iot.cards Private APN |
|---|---|---|
| Network Isolation | None (Exposed) | Full (Isolated) |
| Data Encryption | Device-dependent | VPN Tunneling (IPsec/OpenVPN) |
| Remote Access | Requires Public IP (Insecure) | Secure Private IP over VPN |
| Cyberattack Protection | Low (Exposed to internet) | High (Invisible to hackers) |
Frequently Asked Questions
Do you offer public fixed IP addresses?
No, we do not provide public fixed or static IPs as they represent a significant security risk for IoT devices. Instead, we offer Private APN with VPN, which allows you to access your devices remotely through a secure, private, and encrypted tunnel.
Which VPN protocols are supported?
Our network architecture typically supports IPsec and OpenVPN tunnels. This allows your backend servers to communicate with your IoT devices as if they were on the same local network.
Can I use these SIMs globally?
Yes. Our multi-operator SIM cards provide coverage in over 180 countries, automatically connecting to the best available network while maintaining your private APN settings.
