Is cross-border IoT tracking secure? What you need to know

TL;DR: Cross-border IoT tracking is only secure if you avoid public networks. Threats such as SIM hijacking, rogue base stations, and data sovereignty risks put global deployments at risk. The solution is private-by-default connectivity, SIM technologies like eSIM/iSIM, and real-time management.

What is cross-border IoT tracking?

Cross-border IoT tracking means monitoring assets, whether vehicles, cargo, or equipment—across multiple countries and networks. It’s critical in industries like logistics, EV charging, utilities, and industrial automation.

For many enterprises, cross-border visibility is the foundation of their business model. But seamless tracking comes with a hidden risk: every border crossing exposes your devices to new networks, jurisdictions, and threats.

 

 

Why security matters in cross-border deployments

 

As the IXT white paper warns:

 

“When it comes to IoT, public networks are public territory. Accessible to anyone, including threat actors. It’s time to treat every network connection as untrusted until proven otherwise.” — Henning Solberg, CEO & CTO, IXT

 

When devices roam internationally, security blind spots multiply:

  • Data may route through unknown third-party networks.

  • Devices may attach to weaker, less protected infrastructure.

  • Regulations like GDPR, NIS2, and permanent roaming laws create compliance risks.

 

For businesses, that translates to downtime, fines, reputational damage, and increased operational costs.

 

 

Key security threats in cross-border IoT tracking

 

When IoT devices move across borders, they don’t just cross physical boundaries, they cross network, regulatory, and security boundaries too. Each handoff to a new carrier or jurisdiction creates potential blind spots. Below are the most critical threats enterprises face when tracking assets internationally, and why addressing them at the connectivity layer is essential.

 

1. SIM hijacking & identity attacks

 

Attackers exploit over-the-air (OTA) systems or social engineering to clone SIMs and hijack device identities.

Impact: Unauthorized network access, stolen data flows, and fraudulent device activity.

 

2. Rogue base stations

 

Cheap “fake towers” can impersonate mobile networks. They intercept data, inject malware, or block devices from real networks.

Impact: Cargo or fleet trackers may go offline in transit.

 

3. Data exposure & interception

 

Public mobile networks encrypt only over the air. Once traffic enters the carrier’s core or internet, unencrypted IoT payloads may be harvested or rerouted.

Impact: Sensitive telemetry or payment data can leak.

 

4. Regulatory & data sovereignty risks

 

Cross-border data flows may breach laws. For example, permanent roaming is restricted in markets like Brazil, Turkey, and India.

Impact: Service disconnections, GDPR fines, or operational shutdowns.

 

5. Botnets & DDoS recruitment

 

Insecure IoT devices are prime targets for botnet recruitment.

Impact: Devices meant for tracking end up used in cyberattacks.

 

 

How to mitigate risks in cross-border deployments

Knowing the threats is only half the battle. To keep IoT fleets secure and compliant as they move across regions, enterprises need a connectivity model that doesn’t rely on trust in public networks. The right approach combines private-by-default architecture, advanced SIM technology, and continuous visibility, ensuring security follows the device wherever it goes.

 

  • Private-by-Default Networking

    • Use private APNs, dedicated tunnels, or cloud endpoints instead of shared public APNs.

    • IXT SecureNet routes traffic through isolated, observable infrastructure with direct cloud integration (AWS, Azure, GCP).

 

  • Advanced SIM Technologies

    • Deploy eSIM/iSIM for local profiles, compliance with roaming laws, and stronger identity protection.

    • Avoid static, legacy SIMs that lack OTA resilience.

 

  • Connectivity Management

    • Use a Connectivity Management Platform (CMP) for real-time visibility, anomaly alerts, and bulk SIM control.

    • Gain instant insight into fleet activity across borders.

 

  • Data Pooling Across Borders

    • Avoid per-SIM limits that risk disconnects.

    • IXT Global Data Pool shares usage across SIMs worldwide, keeping devices online and cost-efficient.

 

  • Zero Trust Security

    • Apply “never trust, always verify” principles. Each device and session is authenticated and segmented.

    • This prevents lateral movement and eliminates exposed endpoints.
