How Dutch industry is tackling secure IoT connectivity in 2025
In 2025, Dutch manufacturers are scaling their IoT infrastructure faster than ever, linking sensors, machines, and control systems into intelligent, data-driven factories. But as industrial systems connect more devices to the cloud, the surface for security threats grows too.
From device spoofing and data leaks to network downtime, secure connectivity is no longer just a compliance concern, it’s a competitive differentiator. So how are smart manufacturers in the Netherlands getting it right?
Let’s explore the latest best practices, tools, and strategies Dutch CTOs are using to secure industrial IoT deployments.
Why security is mission-critical for industrial IoT
Manufacturing and process automation environments rely on real-time data, low latency, and uninterrupted uptime. A single breach or outage could lead to:
-
Halted production
-
Compromised safety
-
Lost intellectual property
-
Regulatory fines (e.g. GDPR, NIS2)
According to TNO and the European Union Agency for Cybersecurity (ENISA), industrial IoT is one of the top five targets for cyberattacks in Europe.
Yet, many factories still rely on public mobile networks or outdated SIM setups that weren’t designed with security in mind.

What makes the Dutch market unique?
The Netherlands is a leading hub for industrial innovation—with advanced automation in sectors like:
-
Precision manufacturing
-
Chemical processing
-
Food & beverage
-
Maritime and logistics
But this openness and innovation also bring integration complexity:
-
Diverse vendor ecosystems (OT + IT)
-
Cross-border data traffic
-
Strict EU regulations around privacy and data flow
That’s why many Dutch manufacturers are moving toward secure, private-by-design IoT connectivity.
Private APNs, VPNs, and eSIMs – A quick guide for CTOs
Here’s how technical teams are isolating and protecting IoT traffic:
1. Private APNs (Access Point Names)
A private APN gives your IoT devices a dedicated network path, separate from the public internet. Think of it as your own highway. Safer, faster, and invisible to outsiders.
-
Ensures devices only connect via trusted gateways
-
Allows fire-walling and routing control
-
Reduces exposure to public traffic-based attacks
2. VPN Tunnels (IPSec or IP-VPN)
Establish encrypted tunnels from the SIM network directly to your data center or cloud instance (Azure, AWS, GCP). This enables:
-
End-to-end encryption
-
Geo-fencing of data paths
-
Zero-trust architecture for remote devices
3. eSIMs and iSIMs
eSIMs (embedded SIMs) or the up and coming iSIM allow remote provisioning and profile switching, giving manufacturers:
-
Faster onboarding and rollout
-
Encrypted bootstrapping
-
Vendor agility without spending time and resources physically switching SIMs

A practical checklist: securing industrial IoT deployments
Building security into your IoT infrastructure doesn’t require reinventing your entire network. It starts with a few core principles: isolate what’s critical, encrypt everything in motion, and maintain full visibility at all times. For Dutch manufacturers operating in highly regulated, high-uptime environments, these fundamentals can make the difference between safe scaling and operational risk.
Here’s a practical checklist every CTO and connectivity engineer should consider when planning or reviewing their industrial IoT rollout:
-
Use private APNs or dedicated DNNs: Keep device traffic off public networks by assigning a private access point. This reduces exposure and lets you apply your own security policies from the edge.
-
Route all IoT data through VPN tunnels: Secure your data in transit by encrypting it from the device to your cloud or data center. IPSec or IP-VPN tunnels are commonly used in enterprise environments for a reason.
-
Authenticate devices with SIM-level security: Leverage features like SIM authentication, IMEI locking, and tamper alerts to ensure only authorised hardware connects to your network.
-
Use a CMP with real-time alerting: A modern connectivity management platform can detect anomalies early, notify teams in real time, and allow remote shutdown or suspension of compromised SIMs.
-
Ensure SIMs support remote provisioning: Choose SIMs (eSIM/iSIM) that support OTA updates, credential changes, and vendor switching without physical access—critical for large or distributed deployments.
-
Limit data access with role-based controls: Segment network access to only what’s needed. Devices should only talk to authorised endpoints, and your connectivity stack should reflect this segmentation.
Why security is not a layer, it’s the foundation
CTOs across the Netherlands are rethinking connectivity not as a utility—but as infrastructure for trust.
When IoT deployments are secure-by-design:
-
Operations scale faster
-
Security audits become simpler
-
Your systems become future-proofed for AI, predictive analytics, and robotics
And as supply chains digitise, having secure, flexible control over every connected device becomes a strategic asset, not just an IT concern.
Securing IoT connectivity isn’t just about firewalls or antivirus—it’s about architecture. When security is embedded into every layer of your device connectivity stack, from the SIM to the cloud, your factory becomes resilient by design.
These practices aren’t just nice to have. In 2025’s fast-moving regulatory and threat landscape, they’re essential groundwork for innovation, reliability, and long-term growth.
