Thanks to the rapid evolution of artificial intelligence and a growing, determined group of criminals, cyberattacks are evolving dramatically. The stakes are particularly high for manufacturers, facing unlimited threats with limited bandwidth. In fact, the question isn't if an attack will happen or even when it will occur; it’s how bad it will be. The answer isn’t good. A single security breach can cost a manufacturing company an average of $5.56 million. As production grinds to a halt, those losses can mount by the hour, putting manufacturers under intense pressure to contain the damage and restore operations.
That’s why a growing number of organizations have started implementing layered cybersecurity, also known as "defense-in-depth.” These organizations don’t just ward off more attacks. They also reduce the severity if a breach does occur. According to a study by IBM, organizations with layered security saved an average of $1.49 million per breach and resolved incidents 54 days faster compared to those without layered security. These savings stem from faster response times, better containment, and reduced legal exposure.
Breaking Down the Layers
1) Your People and Their Digital Identities
Cybersecurity begins with people, since employees represent the first line of defense and, unfortunately, one of the greatest vulnerabilities. Verizon’s 2026 Data Breach Investigations Report notes that 62% of breaches included in the study involved a human element. Phishing attacks, weak passwords, and accidental data sharing are common pitfalls. To make matters worse, cyber attackers are shifting toward using known credentials (available on the dark web) to gain access to trusted systems.
Regular training sessions tailored for personnel on the factory floor and in the corporate office can significantly reduce these risks by raising awareness and teaching practical skills. These should include ongoing training simulations, phishing tests, and behavior analytics to identify potential insider threats.
One key takeaway is that establishing a robust security culture is not a once-a-year webinar. It’s a mindset, reinforced with continuous education, tools, and accountability. Security solutions that specifically protect identities are gaining popularity as businesses realize that identities are the new target, before the threat reaches an endpoint.
Real-life incident: A phishing campaign linked to ShinyHunters targeted more than 100 organizations, including manufacturers, using fake domains and voice phishing to target single sign-on accounts. Specialized phishing kits were used to capture credentials and trick employees into bypassing multifactor authentication, potentially giving attackers access to corporate systems and sensitive data.
2) Endpoint Security
Every endpoint is a common point of entry for attackers. Security solutions such as endpoint detection and response (EDR) tools and mobile device management protect devices from compromise … if they’re properly configured and monitored. This becomes more difficult with the remote work and bring-your-own-device (BYOD) policies that continue today. A USB drive brought to the factory floor by a worker poses as much risk as unmonitored industrial machines, touchscreen panels, and handheld devices.
A provider that offers managed endpoint detection and response (MEDR) can continuously monitor behavior and isolate suspicious activity, enabling real-time remediation even when the device is offsite. Thus, MEDR is a must-have cybersecurity strategy.
Real-life incident: In May 2026, Foxconn, a world-renowned electronics contract manufacturer, faced a major ransomware attack by the Nitrogen group, which exfiltrated 8 TB of data and temporarily halted its North American operations, including factories in Mount Pleasant, Wisconsin and Houston, Texas. The incident compromised confidential instructions, schematics, and product details tied to major tech brands.
3) Network and Perimeter Security
Tools at this layer include firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS). They can all stop attacks before they even enter your network.
But to ensure thorough, layered coverage, the perimeter strategy should incorporate geo-blocking and threat intelligence to manage evolving risk profiles, especially for distributed workforces and production facilities. Further, if attackers breach the perimeter, network security measures help contain and limit damage. This can include network segmentation, regular monitoring of anomalous activity, and secure communication protocols like HTTPS and SSH. With these measures in place, threats can quickly be identified and isolated.
In addition, smart segmentation, i.e., separating finance, guest, and operations networks, limits lateral movement by attackers. Combined with zero-trust access principles, this can keep your internal environment controlled, visible, and safer.
Real-life incident: According to a report in the HIPAA Journal, the most common initial access vectors involved compromised perimeter security devices, such as virtual private networks or firewalls, which were prevalent in almost 6 out of 10 ransomware attacks.
4) Application Security
Software applications can present vulnerabilities if not adequately secured. This can include third-party SaaS platforms that teams use daily. Regular updates, vulnerability scanning, vulnerability remediation, penetration testing, and secure coding practices help protect against application-level exploits. However, without visibility into how those tools are configured, attackers may exploit them. One answer is a robust layered approach that helps manufacturers assess their application security posture, enforce strong integration, and maintain best practices.
Real-life incident: In March 2026, Stryker, a global medical manufacturer, suffered a widespread attack on its Microsoft environment, inflicted by a cyberterrorist group. The group carried out a destructive “wiper” attack rather than a conventional ransomware operation. The breach triggered simultaneous factory resets, wiping more than 200,000 corporate devices across 79 countries and severely disrupting the medical technology giant’s global manufacturing, order processing, and shipping operations.
5) Data Security
Data protection is paramount. Sensitive business and operational information requires encryption, rigorous access controls, data masking, and regular backups. A strong data security strategy ensures that even if attackers breach your defenses, critical information remains inaccessible and recoverable.
Thus, data classification, knowing what’s sensitive and where it lives, is step one. Encryption at rest and in transit, multi-factor authentication (MFA) on critical systems, and immutable imaged backups also form part of the modern data security playbook and ensure resilience in the face of ransomware attacks. The right layered-approach cybersecurity provider will support manufacturing companies in defining roles, automating encryption, and enforcing least-privilege access across environments (cloud, hybrid, and on-premises).
Real-life incident: In December 2024, the Holt Group, a leading heavy equipment manufacturer, experienced a large-scale data breach that compromised more than 868 GB of information. The exposed data included the names, Social Security numbers, addresses, and banking details of more than 12,000 individuals.
Defense-in-Depth Approach Is Essential for Trust and Compliance
When it comes to compliance, adherence to recognized security frameworks complements the trust manufacturers work hard to build. NIST CSF and CIS 18, for example, are both frameworks that help improve security posture by encouraging organizations to follow and monitor industry best practices. Layered defenses also align with most compliance frameworks, including the Health Insurance Portability and Accountability Act (HIPAA), the Financial Industry Regulatory Authority (FINRA), the National Institute of Standards and Technology (NIST), and the Cybersecurity Maturity Model Certification (CMMC). All organizations, including manufacturing companies, need to prove security maturity to clients, regulators, and partners, so a layered strategy and adherence to security frameworks must work hand in hand.
The Importance of Offense-Informed Defense
Combining the strengths of a layered cybersecurity approach with application and network penetration testing is also vital. Application penetration testing helps identify and address security flaws in software applications (e.g., web, mobile, APIs). Network penetration testing identifies vulnerabilities in an organization's internal and external networks by finding weaknesses like open ports, outdated software, or poor configurations that attackers could exploit to gain access.
