In the scope of today’s digitized production, manufacturers face a growing threat that often flies under the radar – cyberattacks. From ransomware to internal vulnerabilities, the risks are real, and the stakes are high.
As an MSP that works closely with manufacturing clients, Temple IT understands the unique cybersecurity challenges in this industry. This post breaks down the hidden threats and shares how forward-thinking manufacturers can protect their operations, data, and revenue.
Why Manufacturers Are a Top Target for Cybercriminals
1. Legacy Systems in Operational Technology (OT)
Many production floors still rely on outdated operating systems, which are often no longer supported or patchable. These systems, like old Windows XP machines, control critical machinery but are highly vulnerable to exploitation.
2. IT/OT Network Integration Creates Attack Vectors
Manufacturers benefit from real-time data exchange between business and production systems. But this convergence of IT and OT widens the attack surface. Hackers who breach email or file servers can pivot into manufacturing operations.
3. Complex Vendor and Supply Chain Ecosystems
Every third-party integration, from inventory software to vendor portals, introduces new security risks. If one partner is compromised, attackers can use that access to exploit your environment.
Overlooked Cybersecurity Threats in Manufacturing
• Unmonitored Endpoints & Shadow IT
Employees often add networked equipment or USB devices without oversight, creating blind spots in your cybersecurity posture.
• Insider Risks and Human Error
Lack of employee training leads to password reuse, phishing success, and accidental data exposure. Insider threats, whether intentional or not, are a major risk vector.
• Poorly Configured Third-Party Tools
Tools and platforms integrated without security assessments can serve as backdoors for attackers to enter your systems.
Real-World Cyberattacks That Hit Manufacturing Hard
Schneider Electric – 2024
Hackers infiltrated Schneider’s Jira platform and stole over 40GB of sensitive data, including blueprints and emails. When the company refused to pay the ransom, the data was leaked, exposing sensitive intellectual property and harming brand trust.
Norsk Hydro – 2019
One of the world’s largest aluminum producers, Norsk Hydro, was attacked with ransomware that crippled global operations. They lost over $70 million and took weeks to fully recover, despite refusing to pay the ransom.
These examples show how even world-class companies are vulnerable without robust cybersecurity.
How Manufacturers Can Fix Cybersecurity Gaps
1. Conduct a Manufacturing-Specific Cybersecurity Assessment
At Temple IT, we start with a deep dive into your IT and OT infrastructure to identify vulnerabilities before attackers do.
2. Segment Your Network for Safety
Keep production networks separate from admin tools. This simple practice can contain breaches and limit damage.
3. Train Your Team to Recognize Threats
Human error is still the biggest weakness. Regular cybersecurity training reduces phishing success rates and improves password hygiene.
4. Upgrade Your Email and Endpoint Security
Enable DMARC, SPF, and multi-factor authentication (MFA). Deploy endpoint detection and response (EDR) to catch threats in real time.
5. Work With a Cybersecurity-Focused MSP
Managed IT providers like Temple IT offer continuous monitoring, compliance support, and tailored defenses for your environment.
Conclusion: Don’t Let Cyber Threats Shut Down Your Manufacturing Business
Downtime isn’t just inconvenient, it’s expensive. One cyberattack can stall production, trigger regulatory penalties, and damage your reputation.
