Do You Really Understand Your Cybersecurity Risk?

Why Food & Beverage OT Is Uniquely Exposed

Food and beverage operations combine high throughput, just-in-time logistics, strict regulatory oversight, and narrow process tolerances. From raw material intake to pasteurization, blending, packaging, labeling, and cold storage, automation systems govern safety-critical parameters: temperature, pressure, flow rates, cleaning cycles, allergen segregation, and batch traceability.

Unlike some heavy industries, food production cannot simply “pause and recover later.” Many processes are continuous or semi-continuous. If a pasteurization line stops unexpectedly, product may be lost. If a CIP (clean-in-place) sequence is disrupted, hygiene integrity can be compromised. If labeling systems are altered, allergen information may be incorrect, creating an immediate consumer safety risk.

This is not theoretical. Cyber incidents in manufacturing have demonstrated that ransomware and unauthorized access can halt production for days, disrupt supply chains, and trigger costly recalls.

Risk Assessment: Moving Beyond IT Thinking

A meaningful OT cybersecurity risk assessment in food and beverage must start with consequences—not vulnerabilities.

Traditional IT assessments focus on data confidentiality. In food production, integrity and availability are often more critical. A modified setpoint in a thermal process can create an under-processed product. A manipulated batching system can alter ingredient ratios. A disabled refrigeration monitoring system can spoil inventory across multiple warehouses.

An effective OT risk assessment should:

• Map critical process functions – Identify safety, quality, environmental, and regulatory control points.
• Define worst-credible consequences – Foodborne illness, recall scale, regulatory action, brand damage, worker injury, environmental release, or prolonged downtime.
• Formulate response strategies – An effective and proven incident response plan is critical, and yet this is the most overlooked activity in operational environments.
• Identify mitigation controls – Implement layered safeguards designed to reduce the impact. This may include mechanical failsafes and manual procedures.

Having executed these steps, organizations should then design preventative controls to reduce the likelihood of a cyber incident. However, it is essential that the priority focuses on mitigation controls. Organizations cannot prevent every cyber incident, but they can make the consequences of any incident manageable.

Standards such as ISA/IEC 62443 provide structured guidance for defining security levels based on consequence and a rigorous methodology for risk assessment of operational systems.

In the European context, broader regulatory drivers such as NIS2 Directive and the Cyber Resilience Act are pushing operators and vendors to demonstrate systematic risk management across critical sectors, including food supply chains. Even outside Europe, these regulations are impacting the food and beverage sector.

Consequence Management: Designing for Resilience

Consequence management means assuming that some level of cyber compromise is possible—and engineering the operation to prevent catastrophic outcomes.

While much of the focus in cybersecurity is in preventative controls, the real focus needs to be on mitigation, such as:

• Hard boundaries around safety-critical systems – Protecting pasteurization, sterilization, refrigeration, and allergen segregation controls.
• Independent verification layers – Alarms, quality sampling, and procedural cross-checks that can detect anomalous behavior even if the control system is compromised.
• Manual fallback procedures – Operators trained to continue safe operations during network outages.
• Golden batch baselines and configuration backups – Enabling rapid recovery without guesswork.
• Incident response plans tailored to product safety – Not just system restoration, but recall decision trees and regulatory notification workflows.

Resilience in this sector is as much about people and process as technology. Line supervisors, maintenance technicians, and quality engineers are often the first to notice “something isn’t right.” Training them to recognize cyber-physical indicators such as unexpected setpoint changes, unexplained recipe edits, and abnormal HMI behavior turns the workforce into a detection layer.

Mitigation as a Business Strategy

For food and beverage companies, OT cybersecurity is not simply a compliance exercise. It is risk protection for brand, consumer trust, and operational continuity.

The sector’s increasing digitization, cloud-connected MES systems, remote equipment diagnostics, smart packaging, and energy optimization platforms expand both efficiency and exposure. Risk assessments must be iterative, revisited as digital initiatives evolve.

Ultimately, the goal is to understand where cyber events intersect with food safety, quality, and uptime and to engineer layered controls that prevent a cybersecurity incident from becoming a public health crisis or a brand-damaging recall.

In an industry built on trust and consistency, consequence-focused OT cybersecurity is not optional. It is foundational to resilience.
