Industry 4.0 in plain language: Smarter production, but at what cost?

Machines that send data autonomously. Production lines that adjust themselves. And decisions made automatically based on real-time information. Industry 4.0 is no longer a vision of the future—it’s already a reality for manufacturing companies, including those in Belgium.

That’s why it’s important that you, as a business owner or manager in an SME, understand what Industry 4.0 really means, what benefits it offers, and where the potential pitfalls lie. Because smart production requires smart decisions—and above all: a smart IT partner.

Industry 4.0: What is it, exactly?

Industry 4.0, or the Fourth Industrial Revolution, is a collective term for the ongoing digitalisation and automation of production environments. Whereas machines used to operate independently, Industry 4.0 connects everything through technology: machines, software, people, and data.

Think of:

Internet of Things (IoT): Machines and sensors that continuously collect and share data
Cloud computing: Production data that’s centrally and live available
AI & machine learning: Systems that learn and optimise on their own
Smart automation: From planning to maintenance, without manual intervention

The result? Faster production, fewer errors, more insights, and lower costs.

What does this mean for SMEs?

In the past, this kind of technology seemed reserved for multinationals. Today, the tools are accessible and affordable—even for smaller manufacturers. Many SMEs are already using elements of Industry 4.0, often without explicitly calling it that.

In practical terms, Industry 4.0 delivers SMEs:

Greater efficiency: Processes become smarter and faster
Improved traceability: From raw material to finished product
Predictive maintenance: Less downtime, lower maintenance costs
More flexibility: Adjusting production based on customer demand

But all these benefits come with one major requirement: a secure, stable IT environment.

From smart machines to smart hackers

What’s the difference between IT and OT?

IT (Information Technology) concerns computer systems, networks, and databases that manage information. OT (Operational Technology) involves machines, production lines, and sensors that control physical processes. In traditional setups, the two were separated. But Industry 4.0 connects them. And it’s precisely that connection that makes your production environment vulnerable if security isn’t up to standard.

In a smart factory, everything is interconnected, and that connectivity introduces new risks. Where machines once ran completely offline, they’re now controlled via networks and linked to other systems. That opens the door to efficiency—but also to cyberattacks. The intersection of OT and IT is where vulnerabilities arise, especially when systems were never designed with security in mind.

Cybercriminals are increasingly targeting manufacturing companies. And it makes sense: they know that a single infection or outage can have a massive impact on production and the supply chain. Traditional security measures are no longer enough.

How should SMEs get started with Industry 4.0?

A digital transformation doesn’t have to be all or nothing. Start by mapping out your existing machines and systems. Look at where you’re already collecting data (or could be), automate repetitive tasks, and explore whether sensors or IoT solutions could improve your processes. Most importantly: involve your IT partner from the start so your infrastructure is ready for what’s coming.

Industry 4.0 requires IT partnership

You don’t need to be an IT expert to take steps toward Industry 4.0. But it is essential to have an IT partner who can future-proof your infrastructure, bridge the gap between IT and OT, think proactively about security and scalability, and provide insight into your production environment through monitoring and reporting.
