Manufacturing is the single most targeted industry for cyberattacks, accounting for 26% of all attacks in 2025. Manufacturers are attractive targets because they operate legacy equipment that is difficult to patch, face enormous pressure to avoid production downtime, and are often the weakest link in larger supply chains. A successful ransomware attack can halt production entirely, compromise customer data, and damage relationships with partners who depend on your reliability.

A cybersecurity risk assessment systematically identifies vulnerabilities in your IT and operational technology systems, evaluates the likelihood and impact of potential threats, and prioritizes remediation actions. Tennessee MEP conducts assessments aligned to the NIST Cybersecurity Framework, giving you a structured, objective view of your current security posture and a clear roadmap for improvement. Without an assessment, most manufacturers do not know where their real exposures are until after an incident occurs.

The Tennessee MEP support process follows three phases. In phase one, Tennessee MEP consultants conduct a gap assessment against the NIST Cybersecurity Framework to establish your current security posture and identify priority vulnerabilities. In phase two, consultants work with your team to implement targeted improvements including employee awareness training, incident response planning, and OT and IT security controls. In phase three, ongoing monitoring and advisory support helps you sustain improvements and adapt as the threat landscape evolves.

IT security covers the computers, networks, and software your business uses for data and communications. OT security covers the operational technology on your shop floor — PLCs, SCADA systems, CNC machines, and other industrial control systems. Many manufacturers have connected these two environments as part of Industry 4.0 initiatives, which creates significant new attack surface. OT systems were not designed with cybersecurity in mind and are often running outdated software that cannot be easily patched, making them a primary target for attackers seeking to disrupt production.

Yes. Cybersecurity risk applies to every manufacturer regardless of customer base. Ransomware, phishing, and supply chain attacks do not discriminate by industry segment or contract type. Any manufacturer with networked systems, connected equipment, or digital business processes is a potential target. If your facility holds customer data, proprietary designs, financial records, or relies on uninterrupted production, you have assets worth protecting.
