Today’s cybercriminals are targeting manufacturers with ransomware, phishing attacks, and supply chain threats that can bring operations to a standstill. A single vulnerability can result in downtime, lost revenue, damaged customer relationships, and costly recovery efforts. As technology and production evolve over time, so does vulnerability for new threats to cybersecurity.
RCS helps manufacturers identify risks, strengthen defenses, and protect the technology that keeps their business moving.
What Do Cybersecurity Breaches Mean For Manufacturing?
Cybersecurity threats in manufacturing are more than technical issues—they are business risks that can stop production, delay shipments, and disrupt customer commitments. Ransomware, phishing, weak passwords, unsecured equipment, and vendor access can give attackers a way into critical systems. Historically, manufacturing machinery needed to be physically reliable and safe. Today’s threat landscape requires these systems to also withstand advanced cyber threats that aim to go beyond stealing data, but halt production all together.
For manufacturing companies, the impact can include downtime, lost revenue, safety concerns, stolen designs, compliance problems, confidential data leaks, and reputational damage. As manufacturing becomes more connected, every device, user, and partner can become part of the risk. Two threats that seem to be causing increased vulnerability in recent years are:
Machinery: Legacy OT equipment was not built with today’s cyber threat landscape in mind. Outdated equipment can leave gaps you may not even be aware of.
Complex Supply-Chain: Connectivity and third-party vendors are outside your control. You are only as safe as your weakest trusted partner.
With cybersecurity threats increasing with every technological advancement, having a strong system in place is even more important. Strong cybersecurity helps protect uptime, keep operations moving, and safeguard the business from costly interruptions.
What Do These Attacks Tell Us?
Noteworthy cybersecurity breaches within recent history include:
Nexperia Semiconductor (2024)
A Dutch semiconductor manufacturer for clients as large as Apple, SpaceX, and IBM fell victim to ransomware and hackers exfiltrated intellectual property as well as client data. Dutch chipmaker Nexperia hacked by cyber criminals | Reuters
Hoya Corporation (2024)
A Japanese optical products manufacturer suffered a ransomware attack that led to file theft and a complete halt on production/sales. Hoya Corporation (2024-03-28) Cyber-Attack Hack Breach – The Cyber Security Incident Database (CSIDB)
National Presto Industries (2025)
A U.S. kitchen appliances manufacturer faced a ransomware attack that resulted in a system shutdown and file theft. National Presto Industries (2025-03-01) Cyber-Attack Hack Breach – The Cyber Security Incident Database (CSIDB)
While these companies differ significantly in their specialties and in their countries of origin, they all have one thing in common… they all suffered a significant cybersecurity attack within the last two years. The cause of all three of these events? Ransomware was the culprit in each of these cybersecurity attacks.
Response Matters
It is important to note that National Presto Industries is the one entity out of the three aforementioned companies that did not suffer significant downtime in productions following the attack. They had a disaster recovery plan in place that included clean offline backups.
Conversely, both Hoya and Nexperia experienced full shutdowns and more extensive downtime, causing significant interruption in operations.
This contrast in recovery operations highlights the importance of a tailored cybersecurity approach. RCS delivers practical cybersecurity solutions designed specifically for your business, helping you reduce risk, protect critical systems, maintain productivity, and keep your operations running securely.
Filling in the Gaps
Manufacturing companies depend on technology for production, inventory management, customer communications, and supply chain operations. Unfortunately, many organizations have hidden security weaknesses they don’t know exist. Don’t wait for an attack to find out what your gaps in security are. RCS provides comprehensive cybersecurity assessments and protection strategies to help manufacturers:
- Reduce the risk of ransomware and business interruption
- Protect sensitive customer and company data
- Strengthen compliance and security controls
- Safeguard operational technology and critical business systems
- Improve cybersecurity readiness and resilience
Enforcing a Zero Trust Policy is the best safeguard against cybersecurity threats in the modern landscape. This policy assumes every connection is a threat until proven otherwise and can be achieved through:
MFA/Strict Authentication
Verifying every login prevents stolen passwords from becoming a potential gateway for a breach
Network Segmentation
Establishing digital walls between essential segments prevents a small issue from becoming a complete operations disaster
Continuous Monitoring/AI Enhanced Detection
Identifying a baseline of network activity and flagging unusual activity outside of established patterns can identify potential threats before they become a larger issue
Tighter Vendor Access
Access for vendors through VPN leaves a door wide open. Specific system access prevents vendors from having a wide-open door to all of operations
Identify vulnerabilities before attackers do.
Your Production Floor Is Only as Secure as Your Weakest System.
A cybersecurity breach doesn’t just affect IT. It can shut down manufacturing operations, delay shipments, impact customers, and damage your company’s reputation. RCS helps manufacturing leaders understand their risks and implement cost-effective security measures that protect revenue, productivity, and business continuity.
Schedule a cybersecurity assessment with RCS and gain confidence that your organization is protected.
