In the digital age, factories no longer run solely on electricity, machinery, or people — they operate on data and connected systems. And that makes manufacturing one of the top targets for cyberattacks worldwide.
Manufacturing — the No.1 Target of Global Hackers
According to IBM’s “Cost of a Data Breach 2025” report, manufacturing has ranked as the most-targeted industry for three consecutive years. The average cost of a breach reached USD 4.76 million, with 15% originating from vulnerabilities in the supply chain.
Why has manufacturing become a prime target for cybercriminals?
-
Operational pressure: A few hours of downtime can cause hundreds of thousands of dollars in losses — prompting companies to pay ransom just to recover quickly.
-
Outdated infrastructure: Many factories still operate on legacy systems that lack regular security updates.
-
Complex supply chains: A single weak link among suppliers can spread across the entire network.
-
Thin margins and extreme sensitivity to disruptions: Management often chooses “pay to keep production running.”
For mid-sized manufacturers, the challenge is even greater: limited resources but very real risks.
When a Cyberattack Happens — It’s No Longer Just an IT Issue
In the past, cybersecurity was about protecting data. Today, it’s about protecting production lines and operational capability.
The cyberattack on Jaguar Land Rover (JLR) is a striking example: factories in the UK, Slovakia, China, India, and Brazil were forced offline, supply chains froze, and losses reached billions of dollars.
And JLR wasn’t alone:
-
Bridgestone, the world’s largest tire manufacturer, confirmed a major cyberattack in September 2025 that disrupted all North American operations.
-
Earlier this year, cyber-espionage campaigns originating from China targeted manufacturing and telecom infrastructure across Southeast Asia.
-
According to Bitsight, manufacturing accounted for 22% of all cyber incidents worldwide, the highest among all industries.
Today, IT and OT are deeply intertwined. When ERP, MES, or supplier portals go down, companies don’t just lose data — they lose production capability, customers, and reputation.
What Should Manufacturers Do Right Now?
1. Treat cybersecurity as a core operational capability
Don’t view security as a compliance checkbox.
It’s the foundation for uninterrupted operations.
When systems go down, production stops — along with revenue, customer trust, and brand credibility.
Build and regularly update an incident response plan, and test it frequently.
2. Start with your “front door” — people
People remain the weakest yet most critical link in cybersecurity. Most breaches stem from phishing, stolen credentials, or improper access control.
Simple but effective measures include:
-
Enabling multi-factor authentication (MFA)
-
Implementing role-based access control
-
Providing regular cybersecurity awareness training
3. Strengthen your core systems — protect the heart of the factory
ERP, MES, and supplier portals form the backbone of manufacturing. If compromised, the entire operation shuts down.
Key actions:
-
Prioritize cloud platforms with encryption and real-time monitoring
-
Select vendors offering 24/7 managed security services
-
Apply patches promptly and review access logs consistently
-
Encrypt and segment traffic across industrial protocols (Modbus, PROFINET, etc.)
4. Manage supply chain cybersecurity risks
A security failure at one supplier can immobilize your entire production network.
Assess and control:
-
Who can access your systems
-
Which third-party systems you rely on
-
Your contingency plan if a key partner goes offline
